18 FREDEPaCK BLANCHARD. 



stout and strongly serrate, iu the % the joints 3-6 one-half lunger than wide; 

 punctuation of the head and tliorax variable, but usually distinct, with the larger 

 punctures quite evident, sometimes the thorax is only faintly puuctulate and 

 very smooth and shining. The thorax is very convex, with the sides strongly 

 rounded and feebly to strongly sinuate behind, rather longer than broad, basal 

 striie moderate, base tridentate at middle, a feeble impression in front of the 

 base. Elytra somewhat variable iu form, sometimes subparallel or again nar- 

 rowed and rounded from the humeri, punctate striate, intervals convex and 

 puuctulate. Body beneath closely puuctulate, sometimes strongly, with punc- 

 tures feebly evident on the prosternum, more distinct behind; protliorax with 

 the submarginal lines impressed, usually reaching the middle or beyond, pro- 

 sternal process margined somewhat elevated behind ; hind coxal plates somewhat 

 transverse behiud, the free angles not broadly rounded. Legs black or varied 

 with rufous, tarsi shorter than the tibiaj, the first and last joints about equal iu 

 length. Length .20-30 inch ; 5-8 mm.

The largest females are sometimes confounded in collections with 

 convexulas, which is a more elongate insect with the thorax longitu- 

 dinally distinctly more convex, and the prosternal process not mar- 

 gined behind. It is said by Candeze (iii, p. 165) that several exam- 

 ples of the variety with the feet rufous bear the name Icevieollis in 

 the Dejean collection, and that as Erichson based his description on 

 specimens sent by Dejean it is probable that his kevlcoUis is identical 

 with the present species. 



19. C". togatilS Horn. — Size small, not robust, convex, shining, black, with 

 elytra wholly or partly red, clothed with short and fine pubescence and bristles. 

 Antennffi slender, serrate, longer than the head and thorax in the % , shorter in 

 the 9' the joints more than twice as long as wide. Head and thorax strongly, 

 closely puuctulate with coarser punctures intermixed ; thorax narrowed in front, 

 sides strongly rounded, narrowed and feebly sinuate behiud, hind angles scarcely 

 divergent, median tooth at base obsolete, the lateral ones not very prominent, 

 basal fissures vei'y short. Elytra elongate, subparallel, a little wider than the 

 thorax, at posterior half narrowed and rounded to tip, punctate striate, intervals 

 convex, moderately puuctulate, entirely red, or with apical one third or one-half 

 black or piceous. Body beneath rather closely puuctulate, coarser putictures not 

 evident on the prosternum, except on the lobe, nor on the .sides of the prothorax. 

 distinct behind, submarginal lines of prothorax reaching to anterior third, pro- 

 sterual process feebly elevated, margined behind the c«xse ; hind coxie strongly 

 narrowed externally, the angles broadly rounded. Legs slender, black, varied 

 with I'ufous: tarsi slender, pale, the middle and hind ones with the first joint 

 equal to or slightly longer than the last. Length .27 inch ; 6.5 mm. 



Texas. LeConte collection, Horn, Ulke. 



The single specimen with red elytra is a female, the others are of 

 both sexes apparently. Somewhat resembles the last in size and foi'm, 

 but besides the color, the nuich more slender antennse and narrower 

 hind coxai easily distinguish it.
