 more than one-third longer than wide, the sides nearly straight and gradually 

 divergent from the base, at apical third about two-lifths wider than the pro- 

 thorax ; apex very obtuse ; disk with very large, perforate and close-set fovea;, 

 the bottoms of which are smooth, thin and perfectly transparent. Under sur- 

 face shining and scarcely at all pubescent, tlie legs rather short. Lengtb 1.75- 

 1.8 mm.; width 0.85-0.9 mm. 



Florida (Key West). Mr. Schwnrz. 



The male, serving as the type, has the fifth ventral ver}- short, 

 notdeflexed and broadly truncate at apex, with a rounded shallow 

 siuuation at the middle, the genital segment large and wide, feebly 

 arcuato-truneate throughout at apex and with a transverse ab- 

 rupt and flat-topped elevation on the surface at apex, the anterior 

 margin of which is arcuate and coincident in size and curvature 

 with the median sinus of the fifth segment, these characters be- 

 ing quite different from those of the two preceding species. In 

 the female the bod^' is still more strongly cuneiform, the elytra 

 longer, paler and more oval, the head and prothorax smaller, and 

 the fifth ventral short, fiat and broadly rounded. Two specimens. 



ErRELYHIS n. gen. 



The representatives of this genus differ very radically from 

 Alymeris in several particulars. The epipleuraj are very narrow 

 and graduall}'' become extinct far before the apex of the elytra; 

 the tarsi are long, filiform and very slender, with the basal joint 

 onl^- slightly shorter than the second and the latter fully as long 

 as the fifth. The antennte are better developed and are strongly' 

 serrate toward apex, and, finally, the fourth joint of the maxillary 

 palpi isobliquel}' truncate at apex, thus leading feebly toward the 

 next subfamily. The e^'es are lai'ge, prominent and basal , rounded 

 and with a small feeble anterior sinuation, but are glal)rous and 

 not distincth' less finely faceted than usual. The sculj)ture of the 

 bod^' is much finer and sparser than in the preceding genus, but 

 the lateral edges of the prothorax are quite as distinctly serrulate, 

 the edges of the elytra, however, being almost perfectly even 

 throughout. In one of the sexes there is, in all the 8j)ecies,an el-
