Coleopterological Notices, V. 483 



Inopia Csy., is the same as litoralia Brendel ; this is one of the 

 species coDfounded with puncticollis by LeConte. I agree with 

 Dr. Brendel that the true pimcticollis is, when mature, dark with 

 reddish elytra, the pronotura being- very strongly and closely punc- 

 tate especially in the male. It is abundant in the swamps near 

 New York and Washington. The prothorax in inopia is feebly 

 punctate, especially anteriorly, and not impunctate, as originally 

 stated. 



The few remaining specimens of nevadensis in my cabinet are 

 females, and it is quite certain that the male has never been taken. 

 The head is without a true frontal fovea, but has a short distinct 

 transverse linear and pubescent impression between the antennae ; 

 otherwise it is so similar to the female o( fundata and deformata 

 that I have no hesitation in putting it near them for the present ; 

 in the females of those species there is no trace of the transverse 

 frontal impression.^ 



The species described by me as franciscana is identical with 

 compar as surmised by Dr. Brendel. The name polita given by 

 Brendel to one of our species is preoccupied by King for an Aus- 

 tralian species — possibly belonging to the genus Rybaxis however. 

 Minula Brend. (Froc. Ent. Soc, Phila., 1865, p. 30) cannot be 

 identified, and is not referred to by Dr. Brendel in his recent mono- 

 graph. 



The following species seem to have been overlooked: — 



R. flirtiva n. sp. — Stont, convex, polished, black or piceous-black with 

 paler and more rufous elytra ; legs and antennse pale ferruginous ; integu- 

 ments sparsely and not distinctly punctulate ; pubescence very short but stiff, 

 almost recumbent, rather sparse. Head much narrower but only slightly 

 shorter than the prothorax, deeply trifoveate ; eyes moderate, very convex 

 and prominent, at very nearly their own length from the base ; antennse 

 slender, one-half as long as the body, the club very gradual, joints elongate, 

 fifth twice as long as wide, eighth as long as wide. Prothorax nearly one-half 

 wider than long, widest and evenly, strongly rounded at about the middle ; 

 apex scarcely two-thirds as wide as the base; median fovea small but distinct, 

 lateral large, visible from above. Elytra large, nearly twice as long as the 

 prothorax and fully twice as wide, not quite as long as wide; humeri narrow 

 at base but distinct ; discal stria evanescent at apical fifth. Abdomen, from 

 above, much shorter than the elytra, equally wide, the first dorsal nearly 



1 The small circular fovea in the transverse frontal impression, mentioned 

 in the original description of necadensis, seems to be the result of slight injury 

 to the type, which was the only specimen examined in this connection.
