Var. ponderosa Thorns., 1859, Arc. Nat., p. 89. 

 Length 14-15.5 mm.=.56-.62 inch. 



Habitat—Kan., N. Mex,, Mex. 



Differs from the typical hirtieollis in the larger size, heavier 

 markings, and more brilliant coppery or greenish color. 



We have on the Atlantic seacoast specimens in which the mark- 

 ings disappear more or less. In the specimens before me a dis- 

 cal dot representing the end of the middle band, an apical luuule 

 and some portions of the marginal band remain. I am doubtful 

 whether this is even a race, and I assign no name to it, altliough it 

 is quite generally separated in collections. I cannot discover that it 

 differs in any respect from hirtieollis, except in the disappearance of 

 the elytral markings. 



LiMBATA group. 



Thorax slightly convex, not niargined, suhquadrate ; palpi male pale at hase ; 

 elytral markings broad or confluent making nearly white elytra ; last 

 ventral male asymetrically emarginate. 

 Front hairy, elytra serrulate at tip. 



Markings confluent, elytra white liiiibiita. 



Markings very broad var. hy perborea. 



V. limbata Say, 1823, Jour. Ac. Phil., iii, 142; Schaupp, I. c, p. 93, pi. 3, fig. 

 55 ; Umhigera G. and H. Cat., p. 20. 

 Length 12 mm. ^.48 inch. 



Habitat. Sand hills of Nebraska and Manitoba. Head and 

 thorax green or cupreous ; elytra white ; suture, oblique line and 

 dot or dots green or cupreous; beneath bluish green. Head striate 

 between the eyes, granulate punctate in front and very hairy, the 

 hair in well preserved specimens covering even the top of the head ; 

 thorax slightly convex, quadrate, very hairy, the hair in some speci- 

 mens covering the thorax above entirely ; elytra subparallel in male, 

 broader in female, punctate only in the colored portion, serrulate at 

 apex. Beneath very hairy, almost the entire body being thickly 

 clothed with long white hair. 



Box Butte, Nebraska, May and September ; Imperial, Alliance, 

 Frenchman's River, Neb. ; Prof. Bruner found this species in "blow- 

 outs " where there was little or no vegetation. Sand hills at Doug- 

 las, Manitoba. Aweme, Manitoba, Mr. Norman Griddle. This 

 species seems to be confined to two widely separated localities, and 

 I find no differences in the specimens.
