luteipennis Horn, Csy. nee Lee., olim] ellipsis n. sp. 



5 Body nearly as in binotata but not quite so inflated posteriorly, the 

 pale elytra with less of the suffused blackish coloration, the suture 

 and side margin usually pale, the only distinct discal maculation 

 being a black spot before the middle near inner third; head nearly 

 as in binotata but rufescent and with the sides of the clypeus more 

 parallel basally; prothorax similar in form but with the punctures 

 notably larger throughout, well separated, decidedly coarse and 

 denser laterally; basal bead narrowly subinterrupted medially; 

 elytra a little longer than wide, with similar unimpressed series of 

 irregularly spaced punctures, the latter, however, very much coarser 

 and distinctly umbilicated. Male with the outer ramus of the larger 

 anterior claw much coarser and longer than in binotata though 

 distinctly shorter than the lower lobe; female as usual, having this 

 claw more equally split. Length (cf 9) 9.7-10.4 mm.; width 6.0 



mm. Mexico *irrorata Blanch. 



Body (cT) nearly as in binotata but larger and much stouter, the pale 

 elytra more suffused with black, this extending nearly through apical 

 half, except a medial prolongation of the anterior pale area posteriorly 

 on each elytron ; lateral of the two spots united with the large humeral 

 black area; legs black, with feeble violaceous lustre; head, clypeus and 

 antennae nearly similar, the prothorax similar in general form, lustre 

 and sculpture but larger and with the basal bead narrowly subin- 

 terrupted medially; elytra similar in sculpture but much more in- 

 flated; abundant hairs of the sterna still longer and coarser. Male 

 with the outer ramus of the larger anterior claw longer, not so thin 

 and extending further toward the end of the lower than in binotata; 

 hind tibiae not only much stouter but more strongly sculptured, the 

 tarsi stouter. Length (cf) 10.8 mm.; width 6.7 mm. Louisiana. 



compacta n. sp. 

 6 Body very stout and convex in form, evidently inflated posteriorly; 



scutellum very broadly margined 7 



Body more oblong-suboval, less convex and barely at all inflated poste- 

 riorly, the flat sculptureless margin of the scutellum much narrower 



and less definite 8 



7 Form oblong-suboval, widest behind, very shining, piceous-black, the 

 abdomen in great part paler, the legs blackish; head rather small, 

 not quite half as wide as the prothorax, densely punctato-rugulose, 

 the occiput extending forward broadly at the sides finely, sparsely 

 punctate; clypeus flat, with rather strongly reflexed edges, not quite 

 twice as wide as long, with rounded angles, the sides but feebly 

 diverging toward base; eyes very moderate; antennal club (cf) 

 longer, or ( 9 ) shorter, than the stem; prothorax widest at base, the 

 sides feebly converging to about the middle, then more strongly to 

 the apex, which is sinuate, with the angles about right; base lobed 

 medially, with slightly obtuse and narrowly rounded angles; surface 

 convex, not very finely, somewhat irregularly and sparsely punctate, 

 not differently toward the sides; scutellum sparsely punctate; elytra 

 in great part piceous-black, becoming nubilously pallid medially
