arcuate and convergent to the apex from just before the middle, convergent 

 and strongly sinuate in basal half; base and apex equal; disk convex, even, 

 finely densely evenly and very distinctly punctate. Elytra more than twice 

 as long as the prothorax and three-fourths wider, longer than wide ; humeri 

 rounded and exposed ; sides just visibly divergent throughout ; disk strongly 

 densely punctate. Abdomen short behind the elytra, feebly, sparsely punctu- 

 late. Legs short but slender ; hind tarsi short, scarcely one-half as long as 

 the tibise. Length 2.7 mm. ; width 1.0 mm. 



Penosylvaiiia. 



The single speeinien is a male, having the sixth ventral feebly 

 sinuato-truncate at apex. The maxillary palpi are as in Lesteva 

 pubescens, the second joint stouter than the third and fourth, the 

 third small, not quite as long as wide and scarcely more than one- 

 sixth as long as the fourth. In Lesteva the head is constricted at 

 a much greater distance behind the eyes, the ocelli being notably 

 more basal, and the second antennal joint is rather shorter than the 

 third. In Pseudolesteva the second antennal joint is much shorter 

 than the third, and the fourth palpal joint is shorter and more gradu- 

 ally pointed toward apex. 



IJiVAMIS n. gen. 



The species previously described as Lesteva truncata (Bull. Cal. 

 Acad. Sci., I, p. 322) demands without any doubt a special genus 

 for its reception. It is most closely allied to Artochia, resembling 

 that genus in the basal position of the eyes and obsolete tempera, 

 but differs in palpal structure and in the tarsi. In Unamis the 

 hind tarsi are long and slender, with the basal joint equal to the 

 next two together. 



ARTOCHIA n. gen. 



Body small, rather narrow, the head small, triangular, with the 

 front somewhat prolonged ; eyes basal, densely setose, the head 

 transversely constricted immediately behind them ; ocelli widely 

 distant and on the edge of the transverse constriction. Antennae 

 incrassate, much shorter than in any other genus of this group. 

 Maxillae with the inner lobe elongate, arcuate aud feebly ungulate 

 at apex, with an inner fringe of very minute setae ; outer lobe as 

 long as the inner, very slender, gradually thicker near the base, 

 arcuate at apex, the latter with a terminal tuft of minute setae; 

 cardo very large, elongate, densely pubescent. Labial palpi with
