520 CASEY 



the humeri exposed basally, the calkis rather strong ; surface 

 impressed near the suture apically, the convex intervals there 

 becoming stronger, having throughout even, slightly impressed 

 series of moderately coarse and widely spaced punctures, which 

 are but little coarser lateralh' but becoming asperate toward tip ; 

 the intervals feebly rugulose, slightly convex, minutely, sparsely 

 and confusedly punctulate ; abdomen finely but strongly, sparsely 

 punctate and somewhat pubescent. Length 10.7-12.3 mm.; 

 width^. 3-5.0 mm. Ecuador (Guayaquil), — Rolle. 



solieri n. sp. 



The four examples sent me vary a good deal in size, the 

 smaller probably being males but without any distinct sexual 

 characters. 



The genus Etmotiodes has for its type a species which may 

 be described as follows : — 



Body stout, oval, convex, somewhat alutaceous, blackish-castaneous, 

 virtually glabrous ; head very coarsely, not closely punctured 

 medially, less coarsely and more closely laterally and anteriorly, 

 the last antennal joint elongate, pyriform, with the apex com- 

 pressed and truncate ; prothorax twice as wide as long, the apex 

 scarcely narrower than the base, the sides very evenly and rather 

 strongly arcuate throughout, the basal angles obtuse and blunt ; 

 surface evenly and moderately convex, the pronounced apical bead 

 ending abruptly inwardly at lateral fourth, the punctures moderately 

 coarse and sparse, deep and without median smooth line medially, 

 becoming coarse and closer but not dense laterally ; scutellum 

 ogival, wider than long; elytra two-thirds longer than wide, 

 nearly one-half wider than the prothorax and more than four 

 times as long, rapidly narrowed and acutely ogival in about pos- 

 terior third, the sides parallel, feebly arcuate to the rectangular 

 but rounded humeri, which are widely exposed at base, the surface 

 even, with the punctures perforate, coarse and sparse, still coarser 

 but only a little closer laterally ; abdomen finely but strongly, 

 sparsely punctured medially. Length 11.7 mm. ; width 5.3 mm. 

 Argentina (Mendoza), — Rolle brevicoUis n. sp. 



The sex of the single specimen before me is not evident. The 

 large rounded epistomal lobe is finely pectinate about its contour. 

 The type of Omofheres may be thus described : — 



Form very stout, convex, oval, polished, subglabrous, castaneous in 

 color ; head moderately coarsely but not very closely punctate, 

 more closely on the flattened trapezoidal epistoma ; prothorax 

 relatively small, nearly one-half wider than long, the sides evenly 

 and moderately converging and evidently arcuate from base to 

 apex, subparallel in about basal third, the basal angles obtuse 

 and somewhat blunt, the apical^acute and not at^all blunt ; surface
