This species is near R. Argus, Paso. Compai-ed with that insect 

 it is of somewhat broader and more robust build with the elytra 

 quite strongly emarginate at the apex, the extremities of the 

 emargination of each elytron distinctly pointed, — almost spiniform. 

 The eyes are less approximate than in Argtis, and the pubescence 

 of the upper surface is considerably different ; taking the whitish 

 pubescence as the ground the fulvous pubescence is laid on in 

 such fashion as to form a sharply defined pattern which on the 

 elytra has a sinuous and mostly transverse linear arrangement ; 

 while the black granulations and spots are much like those of 

 Argus, except that the black patches are much larger about the 

 middle part of the elytra than elsewhere, where some of them are 

 transversely elongate, and they are so placed on a wide space 

 extending across both elytra as to look like a conspicuous band of 

 spots. The underside, legs, and antennae are much like those of 

 R. Argus. The elytra present no indication whatever of costse. 

 The shoulders are black as in Argus.

NiSOTRA SUBMETALLICA, Sp.nOV. 



Ovata ; convexa ; nitida ; subtus (prosterno testaceo excepto) 



nigra ; supra testacea, elytris paliide viridi-micantibus, 



antenuis nigris (articulis basalibus 4 testaceis), pedibus 



testaceis (femoribus posticis antice nigricantibus) ; subtiliter 



(in elytris vix seriatim) punctulatis. [Long. 1|^, lat. 1 line. 



The prothorax is (by measurement) just twice as wide as long; 



its puncturation is very lightly impressed and by no means close ; 



its .sides are gently and somewhat sinuately arched, its front 



angles decidedly its hind angles scarcely directed outwards; its 



anterior discal furrows are elongate and extremely deep, and it 



has two basal foveae on either side, the outer ones much feebler
