While there are these essential differences it will be observed that 

 Fabricius describes it in association with species with inflated claw 

 joint, the two species immediately preceding belonging to Lithononia 

 and (lEdionychis, the two following to Q^dionychis and Asphtera. 

 It is probable that the name should be used rathei- for some of the 

 larger ffidionyches from one of the West India islands or Cayenne. 

 The error in the interpretation of Fabricius' species is due to Illiger. 

 It seems to me that I am justified in rejecting the name from our 

 fauna. 



The remarks by Suffrian (Wiegm. Archiv. 1868, i, p. 180) are so 

 unsatisfactory that it is impossible to say whether he had the true 

 Fabrician species before him or not. It is more than likely that he 

 did not see either the present species or collata. 



Occurs from the New England States to Kansas and Texas and 

 Florida. 



14. D. cervicalis Lee— Closely resembling xanthomelsenn., and diflerinj; 

 ouly as follows: Anteuufe entirely piceous Legs entirely black, the coxa; yel- 

 low, underside of body entirely yellow. Abdomen coarsely, moderately closely 

 punctate, pubescence feeble. Length .20 inch. ; 5 mm. 



Of this species I have seen but one specimen from Georgia. Le- 



Conte says (Ins. Kans. p. 25) that it occurs also in Kansas. This is 



the only species with blue elytra with the underside entirely pale, 



and, with the exception of trkuigalarls, the only one with entirely 



black legs. 



15. D. varicornis n. sp. — Oval, slightly oblong, moderately convex; head, 

 thorax and entire underside yellow, elytra brilliant violaceous blue. Anteiiuai 

 nearly half half as long as the body, piceous, the four basal and one or two ter- 

 minal yellow. Head entirely yellow, smooth, except a fovea of coarse punctures 

 near each eye, frontal carina broad and obtuse, tubercles small. Thorax twice 

 as wide as long, sides feebly arcuately narrowed to the front, anterior angles very 

 obtuse in front, a slight sinuatiou of the margin behind them, surface smooth, 

 entirely yellow. Scutellum black. Elytra a little wider at base than the thorax, 

 humeri rounded, umbone distinct, smooth, disc finely sparsely punctate at base, 

 smooth at apex. Body beneath entirely yellow. Abdomen smooth, sparsely 

 punctate. Anterior and middle femora yellow, the posterior tipped with piceous, 

 tibise and tarsi all black. Length .24 inch. ; 6 mm. 



This insect bears such a close resemblance to Asphcei-a Imtrans as 

 to be readily mixed, except by careful examination. The generic 

 characters which separate them are also quite feeble, the claw joint 

 not being very different in the two. There is, however, a distinct 

 sinuatiou of the apex of the hind tibia aiiove the tarsus in Aspha'ni 

 not seen in the jiresent genus.
