The top may be very large; labrum outstanding and crescent-shaped; ocelli three, not positioned at the base of the ridge between the antennæ, (as described by Mr. Grey,) the anterior one being considerably in front of it, and the posterior pair at its hinder half: mandibles very lengthy and toothed on the extremity; palpi very lengthy and slender, composed of lengthy joints, the maxillary pair terminated by a fleshy wart, (not an acute spine, as acknowledged by Mr. Grey;) legs lengthy, particularly the hinder ones, the thighs of that are a lot thickened; tibiæ strongly spined; tarsi 4-jointed, however having a fleshy lobe at the base of the radical joint on the below side, by which character it is related to the present family, and not with that of which we’re next to speak. H, the pinnacle; a, a, the eyes; b, the ocelli; c, one of many antennæ; T 1, upperside of the prothorax; l′ one of many prothoracic legs; T 2, upperside of the mesothorax; S c, scutellum greatly developed and extending over the metathorax and a part of the abdomen; h one of the hemelytra; hc, the leathery basal portion of the hemelytra; hm, the membranous or apical portion; l″ one of many mesothoracic legs; T 3, higher facet of the metathorax, drastically reduced in size, supporting the wings (one in every of which is prolonged, W 2), and the metathoracic or third pair of legs l′′′-A, abdomen.- Fig. 7. The head and prothorax of the identical insect seen from beneath; a, the attention; c, base of antennæ; lr, labrum or higher-lip, long, and transversely striated; lb, the four-jointed lower-lip remodeled into an elongated canal for the reception of 4 slender setæ, gg, hh, which signify the mandibles and maxillæ; s, raised portion of the underside of the top, forming a gutter, in which the bottom of the labrum rests; T 1, underside of the prothorax; l′ base of one of many prothoracic legs; Z, the cavity of the prothorax, into which the anterior narrowed part of the mesothorax (marked in fig. 6 by the letter z) is obtained.-Fig.
3) is a really lovely one and bears considerable resemblance to that of a sphinx each in type and markings. A spokesman of the masculine inverts said the bisexual theory in its crudest type in the following words: “It’s a feminine mind in a male physique.” But we have no idea the traits of a “feminine brain.” The substitution of the anatomical for the psychological is as frivolous as it is unjustified. Sometimes they are distant from each other, (Scutellera, Edessa, &c.) at other occasions with their edges nearly touching (Reduvius, &c.) In shape additionally they provide some differences, the usual spherical type being exchanged, in Fulgora serrata, for an oblong with a longitudinal impression; in another instance of the same genus, (Fulgora diadema,) the depression is circular. The males are and not using a circular spot at the base of the tegmina, and their stridulent observe is therefore totally produced by the friction of the thighs in opposition to the tegmina and wings. Some have the wings and tegmina good, others are apterous; in some the males have an ocellus at the base of the tegmina, in others it’s wanting; the mandibles of sure species are short, trigonate, and nearly entire on the inside edge, whereas others have them lengthy, acute, and dentate; lastly, the ovipositor is typically curved and generally straight.
This handsome and not unusual species, is nearly an inch and a half in length, the overall colour inexperienced, with dark brown spots on the tegmina, and a few smaller ones on different parts of the body; the ovipositor of the female curved. The sphere of the sexual must be thought to be a fraction merely of the overall academic subject. The true “black-beetles” or “churchyard beetles” (Blaps) (fig. 22) belong to this family; like members of several allied genera they’re sooty in colour, and somewhat resemble ground beetles (Carabi) in general appearance. Savigny appears to regard the basal section alone as representing the true lip. In most cases, it occupies about a third a part of the floor, generally the half, (as in Lygaeus,) at different instances two-thirds, (in Alydus,) and three-fourths in sure Reduvii. Occasionally, it’s so extensive as to cut back the membranous portion to a slim band at the tip, and in a quite a few race it may be said to occupy the entire floor, rendering the hemelytra very much like the tegmina of Orthoptera. The thorax and tegmina are brownish yellow, the latter with a crenated white ray along each; abdomen marked with yellow and black spots; legs brown.
One of the largest migratory locusts recognized; the tegmina often measuring eight or nine inches from one extremity to the other. There is cause to imagine that a number of the ingenious observers, who have turned their attention to this topic, have carried their views quite too far, from a wish to show a sure uniformity of organisation amongst totally different tribes-an fascinating inquiry, but one which requires to be pursued with nice caution, as the fancy is so apt to guide us astray. Governor Phillip appears to have each requisite to ensure the success of the endeavor intrusted to him, as far because the qualities of one man can ensure it. Monopterus albus is native to a lot of East and Southeast Asia, ranging west so far as India. M. tersa is a local both of North and South America, in addition to of the West Indian Islands. This is the case with the Fulgoræ, and in a well known species of that tribe, it’s inflated into a large mitre-shaped appendage of a very exceptional appearance. The wings are pale brown and clear, with transverse undulating dusky streaks, each having a big ocellated spot at the extremity, consisting of a black ground with two white crescents, the exterior edge reddish and surmounted by a black streak.
