Horn.] 1*-K) [Feb. 21, 



Elytra black and shining, with large smooth spaces between which the 

 finely punctured portions are covered with cinereous pubescence forming 

 anastomosing lines. Body beneath black, shining, sparsely pubes- 

 cent and sparsely punctulate. Length .36-.S4 inch ; 9-14 mm. 



Male. Anterior tibi;e unicalcarate, last joint of maxillary palpi elongate 

 oval, truncate at apex. 



Closely allied to the next species, and differs in the smoother surface 

 and the form of the last joint of the maxillary palpi. It is probable 

 that the surface character may change in localities and that the pubes- 

 cence may cover as much of the surface as in the next species. Should 

 this occur the form of the last joint of the maxillary palpi of the male 

 affords the only means of distinguishing the two species. 



Occurs in Arizona.

Black, opaque, cinereo-pubescent. Head densely and finely punctured. 

 Thorax as broad as long, anterior angles broadly rounded, median line 

 finely impressed, surface finely punctulate. Elytra opaque, cinereo- 

 pubescent. with round denuded spots, distinct from each other, and which 

 are opaque and finely scabrous. Body beneath black, moderately densely 

 punctulate and sparsely pubescent. Length .30-. 70 inch ; 8-18 mm. 



Malt . Last joint of maxillary palpi as broad as long, rounded and flat- 

 tened, penultimate joint broadly triangular. Anterior-tibiae unicalcarate. 



The females are always larger than the males, and with the denuded 

 spots more numerous and of greater size. The males are sometimes very 

 minutely maculate and superficially resemble E. sericans. 



Abundant from New Mexico northward to Dakota and thence westward 

 to California and Oregon.

This species is too well known to need description here. Length .50- 

 .80 inch ; 13-20 mm. 



Occurs abundantly in early summer on the vines of potato and tomato, 

 in the Middle States.

Closely resembles the preceding species; differs as follows : Elytra with 

 three black vittse, legs pale rufo-testaceous, body beneath never entirely 

 black. More slender than E. vittata. Length .70-.80 inch ; 15-20 mm. 



Occurs in the Southern States where it replaces the preceding species 



E. nigritarsis, Lee. Pro. Acad. 1853, p. 340. 



Head piceous, densely punctulate, sparsely cinereo-pubescent. Thorax 

 as wide as long, rufo-piceous, median line finely impressed, disc densely 

 punctulate, sides slightly divergent behind, in front broadly arcuate to 

 apex. Elytra rufous inclining to pale brownish, finely scabrous, and
