fine and not dense but distinct, the median stria fine; elytra about 

 a third longer than wide, gradually and distinctly inflated behind, 

 barely twice as wide as the prothorax, the striae rather fine but 

 evidently punctate, impressed, the intervals broadly convex; dorsal 

 punctures a little behind basal, and before apical, fourth. Length 

 6.2 mm.; width 2.7 mm. Illinois fuscata Dej. 



Body not quite so large, relatively broader, rather convex, shining; 

 head rufo-testaceous, the pronotum a little paler; elytra black, 

 each with a large oval spot extending from behind the middle to 

 basal sixth or seventh, internally to the first stria and, externally, 

 separated from the pale margin by a vitta of about two intervals, 

 extending to the apical fascia, which is broad, emarginate on the 

 suture and narrowly but clearly separated from the anterior spots; 

 under surface and legs pale; head five-sixths as wide as the pro- 

 thorax, with large and very prominent eyes; surface nearly smooth, 

 usually with two small approximate fovese on a transverse line 

 through the anterior part of the eyes; antennae not very slender, 

 shorter than in the preceding, less than half as long as the body and 

 pale flavo-testaceous in color; prothorax fully twice as wide as 

 long, the rounded and well reflexed sides very converging apically, 

 the hind angles rather blunt at tip; rugulosity rather fine, not 

 dense; median stria fine but deep, entire; elytra only about a fifth 

 longer than wide, gradually and distinctly inflated behind, evidently 

 less than twice as wide as the prothorax, the striae impressed, nearly 

 smooth, the intervals somewhat strongly convex; dorsal punctures 

 very small, at basal third and apical fourth. Length 5.0-5.5 mm.; 

 width 2.5-2.65 mm. Texas (Brownsville), — Wickham.

14 — Apical pale areas of the elytra separated narrowly from the anterior 

 pale areas, or else joining by a very narrow isthmus; body smaller 

 in size. Shining, black, the pronotum piceous to black, with the 

 moderately reflexed margins abruptly pale; elytra pale, with a 

 narrow scutellar area connected along the suture with a large oval 

 posterior sutural spot, and also with a frequently isolated smaller 

 external spot just behind the middle, black, the apices behind the 

 posterior pale area infuscate; under surface piceous, the legs and 

 epipleura pale flavate, the tarsi not darker; head not quite as wide 

 as the prothorax, shorter than wide, with moderate though very 

 prominent eyes; surface feebly rugulose laterally, especially at 

 base; antennae slender, half as long as the body, pale flavo-testa- 

 ceous; prothorax twice as wide as long to a little less, the moderately 

 rounded sides very feebly sinuate just before the sharp basal angles; 

 surface nearly smooth, the faint rugulosity scarcely discoverable; 

 median stria fine, entire between the basal transverse sulcus and 

 the apical margin; elytra a fourth longer than wide, slightly dilated 

 behind the middle, twice as wide as the prothorax or less; striae 

 fine, barely at all impressed, feebly and irregularly punctulate, the 

 intervals not quite flat; dorsal punctures small, at basal third and 

 apical fourth. Length 3.3-3.6 mm.; width i. 4-1. 65 mm. Cali- 

 fornia (the locality unrecorded) metuens n. sp.
