1893.] FROM ST. VINCENT, WEST INDIES. 717 



Length to end of abdomen 1-g millim., to tip of wing-covers 

 3 millim. ; width across lobes of pronotum 2 millim. 



The less matiu'e 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 Corythuca, StSl. 

 Examples of a species of this genus, approaching C. gossyjiii, 

 Fabr., were taken on the island by Mr. Smith, but the few specimens 

 are either immature or not in condition for accurate identification.

Body and members more robust than in E. longipes, De Gr., 

 and the other normal species. Obscure fulvo-testaceous, un- 

 polished, 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. Eostrum 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 tibiae ; 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 con- 

 tracted, 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, 

 thej posterior end being obliqiiely truncated in the femah^, but
