d'Orbigny says of this species, which I have not seen, that it is 

 closely allied to 0. hycena, the latter differing from it by having the 

 intervals of the elytra plane, with an equal surface, and with the 

 greatest part rilled with very fine granules very little closely set, and 

 disposed in two series ; the punctuation of the prothorax is less deep 

 and more spread. It is also closely allied to 0. crctus, Pering., which 

 dit't'crs by the prothorax being much more closely punctate with the 

 intervals between the punctures wrinkled, and the sides plainly 

 sinuate near the basal angle.

I had most probably seen a wrongly named co-type of Fahraeus 

 when I placed this species on synonymy with 0. piceus and 0. lugens 

 of the same author. Harold, however, has united with this species 

 0. scahrosus and 0. pedcstris, Fahr. I have done the same for the 

 two latter (Catal. i., p. 199). According to d'Orbigny my 0. cretus 

 is the 3 of 0. setosus, the type of which is a ? •

"Opaque, black, very briefly pubescent on the upper side, but 

 with the pubescence longer on the head. Head strongly punctate, 

 clypeus more or less rugose, hardly sinuate at apex, irons arcuately 

 carinate, vertex in the $ with a short conical tooth, or a tubercle 

 situated nearly in the middle of the space between the eyes, in 

 the $ with a straight, somewhat long carina situated between the 

 eyes near their posterior margin ; prothorax strongly but not densely 

 punctate and more minutely and sparingly so in the median part of 

 the base, briefly transversely callose or indistinctly bi-tuberculate 

 in the middle of the anterior part; sides hardly sinuate laterally, 

 base marginate ; elytra broadly striate, with the intervals plane, and 

 with simple, moderately deep, dense punctures set without order; 

 pygidium simply and moderately strongly punctate." 



d'Orbigny compares this species, which 1 have not seen, to 

 0. minutus, Hausm., which differs by the prothorax being very 

 closely punctate, and having no projection in the anterior part, 

 while in the J the carina of the vertex is much shorter and occu- 

 pies only half the width of the area between the eyes." 



1 am fain to think, however, that this species is merely a
