Atlantic States, not rare. I have no hesitation in placing these two 

 II iraes as synonyms. The form of the prothorax is quite characteristic, 

 obloiij; anil not oval. The differences in the descriptions are easily 

 accounted for by the fact that Newman described the elytra as having 

 six grooves, but did not observe that the interval between the two outer 

 ones was abbreviated in front, about one fourth from the base. Germar 

 on the contrary, regarding the costae as more conspicuous than the 

 intervening grooves, and omitting the sutural one, described the elytra 

 as four-costate, with the outer costa, (corresponding with the region 

 from the fourth to the sixth grooves of Newman), as double for a 

 part of its course. For the purpose therefore of distinguishing more 

 easily the present one from allied species I would offer the following 

 diagnosis. 



C SCUlptile. — Head obliquely narrowed behind the eyes, base nearly 

 truncate; eyes narrow, confined to the upper surface of the head. Prothorax 

 nearly twice as long as wide, oblong, sides broadly rounded, base and ai)ex also 

 broadly rounded. Elytra with the costae narrower than the deep intervening 

 grooves, subtnarginal costa abbreviated in front at the anterior fourth or rarely 

 the fifth, and usually confluent with the next one at the 

 posterior fourth. Length 5.5 — 7.5 mm. ; .21 — .30 inch. 



'J,. — Front thighs distinctly toothed; front tibiae rather 

 suddenly dilated on the inner side, above the oblique 

 groove: then sinuate; middle and hind tibiae subsinuate 

 on the inner side, produced inwards at tip into a sharp process. Prosternuin 

 with a broad stripe of velvety surface; ventral segments with spots of similar 

 velvety lustre. 



9. — Front thighs not toothed; front tibiae with only the usual arrangft- 

 nient of hooks and teeth; middle and hind tibite simple, with two small 

 apiciil spurs. 



Slight variations occur in the arrangement of the outer costae of the 

 e'ytra, which I have indicated in the diagnosis. 



C calC'Jiraliiin. — Piceous, shining, elongate. Head obliquely narrowed 

 lichind the eyes, base subtruncate; eyes narrow, rather prominent, confined to 

 the upper surface of the head. Prothorax nearly twice as long as wide, regu- 

 larly elongate-oval, (not oblong); angles not apparent. ' Elytra with the costae 

 towards the base wider than the intervening furrows, submarginal costa and the 

 next entirely confluent, with only a line of punctures in- 

 dicating the separation. Length 7.5 mm. ; .30 inch. 



'J,. — Front thighs not toothed; front tibiae very feebly 

 ■ lilated on the inner side; middle and hind tibite with 

 a large pointed apical process cm the inner side, one-half 

 the length of the tibiae, apical spurs two, small straight; under surface without 

 velvety spots. 



5. — Middle and hind tibiae simple.
