but not produced at middle. The female has the two carinae distinct 

 as usual, and a less convex prothorax than the male without declivity 

 in front. The intervals of the elytra are distinctly biseriately punc- 

 tate. The anterior tibiae are alike in both sexes. Less developed 

 males are hardly distinguishable from the females, except by the 

 different form of the last abdominal segment.

This is a good species and not a variety of janus. It is more 

 closely related in form, sculpture and armature of prothorax to Jiccatc 

 than to any other of our North American species. The color is 

 metallic green, base and apex of elytra and sometimes the pygidium 

 more or less yellowish. The head has the clypeus with a similar 

 process as hecate; in the male the upper carina is weak at middle, 

 but produced on each side into a more or less prominent, acute tu- 

 bercle, or small horn, the prothorax is granulate, produced at middle 

 nearly as in hccatc, but the process is generally broader at apex and 

 without any bidentate process within the apical emargination. 



The female has the prothorax anteriorly produced into a very 

 short, broad protuberance. 



Onthophagus velutinus Horn. 



Horn, Trans. Am. Ent. Sci., Vol. V, p. 140. 



This is a smaller and slightly more elongate species than hccatc of 

 uniform black or brownish black color, the prothorax rather sparsely 

 and more finely granulate than in hecate, the clypeus emarginate and 

 the posterior carina of the head of the male small and produced into 

 two moderately long slender horns. The female is unknown to me. 

 It occurs in Lower California and Arizona.
