appears to be the slender filiform antennae, a differential character 

 corresponding with that made use of by Mr. Champion for the 

 separation of Allecula and Hymenorus. 



Our species are found on foliage of low plants and are moderately 

 abundant. They are easily differentiated as follows: — 



Elytra without distinct series of punctures. 



Fourth joint of the maxillary palpi long and slender. 



Antennae with the third joint distinctly shorter than the fourth, at least 

 in the male. 

 Eyes very large, the front broadly, deeply impressed ; color pale 



throughout ioweiisis 



Eyes small or moderate ; front not impressed. 



Color black, the prothorax rufo-ferruginous ; elytral punctuation 



sparse discolor 



Color piceous-black throughout ; elytral punctuation extremely dense. 



tenebrosa 

 Antennae with the third and fourth joints equal or subequal, elongate. 

 Eyes moderate ; elytral punctuation and pubescence exceedingly dense ; 



color pale ochreous-flavate throughout sericea 



Eyes small, not prominent ; punctuation of the head and pronotum 

 fine, very dense ; elytral punctures sparser ; color variable. 



variabilis 

 Eyes very small, convex and prominent ; head and pronotum rather 



coarsely punctate ; size smaller lllSCltiosa 



Fourth joint much shorter and more dilated, but with the outer side dis- 

 tinctly longer than the apex ; punctuation very dense throughout ; color 



piceous-black pillla 



Fourth joint robust, the outer side but slightly longer than the apex. 



Elytral punctuation sparse ; eyes small, the elytra without impressed 

 lines except the two sutural toward apex. 

 Third and fourth antennal joints equal in both sexes ; prothorax small, 



much narrower than the elytra quadristriata 



Third joint shorter than the fourth ; prothorax larger, subequal in 



width to the elytra Itionticola 



Elytral punctuation dense ; eyes large ; third antennal joint shorter than 

 the fourth ; elytra with fine but distinct impressed lines throughout 



the width oblongula 



Elytra with series, more or less complete and sometimes feebly impressed, of 

 small punctures ; maxillary palpi with the terminal joint but slightly 

 shorter and more robust than in sericea; eyes large. 

 Eyes in the male separated by scarcely two-thirds their own width. 



valida 



Eyes in the male separated by fully their own width ; form more oblong 



and parallel ; elytral series feebly impressed texana
