The less mature individuals of this species are paler and almost translucent in the meshes of the wing-covers, while the fully mature ones are tinged with yellow and more opaque. About one dozen specimens were collected by Mr. Herbert H. Smith. Genus C O R Y T H U C A , Stal. Examples of a species of this genus, approaching C. gossypii, Fabr., were taken on the island by Mr. Smith, but the few specimens are either immature or not in condition for accurate identification. Fam. EMESIDJE. Genus EMESA, Fabr. EMESA ANGULATA, sp. nov. Body and members more robust than in E. longipes, De G., and the other normal species. Obscure fulvo-testaceous, unpolished, with the sides of the head and thorax broadly blackish piceous. Head stout and deep, remotely punctate in patches, obsoletely scabrous, minutely pubescent, the division behind the stricture longer than the one before it, base of tylus armed with a short curved spur. Rostrum reaching the anterior coxae, the basal joint stout; the second a little longer and thicker, tapering towards the tip; the third pale testaceous, tapering at base, swollen, growing quite slender, longer than the first and second united. Antennae slender, filiform, of medium length, fuscous, pale at base, and sometimes with an obscure band on this paler portion, the basal joint equal to the thorax in length, the second much shorter. Middle and posterior legs filiform ; the tibiae more slender than the femora, black at base and banded with black, in four spots upon the femora and three upon the tibise; anterior femora thick, subcylindric, compressed, obscurely banded with fuscous, set with two sizes of teeth from before the middle to the tip, the inner tooth much longer than the others; the tibiae fuscous with a pale band, the tarsal nail not quite reaching to the inner tooth. Pronotum obsoletely scabrous and almost flat above, faintly marked with a longitudinal impressed line, the anterior half a little swollen, back of this the lobe is a little contracted, while the posterior lobe is quite small, and elevated into two transverse toothed callosities, anterior angles tubercular. Mesonotum taperingly contracted from the middle forwards, so as to be much narrower than the pronotum, while the basal portion swells to nearly the width of the pronotum, the middle line has a slender carina which runs back through the grooved metanotum ; the metanotum is much shorter than the mesonotum and has carinated sides. The underside, including the venter, is smooth, somewhat glossy on the sternum, with the venter dusky and dull. The abdomen is thick and gradually widens posteriorly, the,, posterior end being obliquely truncated in the female, but |
