In the " Catalogus Coleopterorum " of Dr. Gemminger and 

 B. von Harold, I find that the species described by me some 

 years ago under the name of 0. rubrimacutatus, is put down as a 

 synonym of this species. This is incorrect, I have both species, 

 there is a marked distinction between them as regards both size 

 and sculpture. 



I may here mention two other errors in that publication. 

 My Onthophagus furcatus which is put down in the Catalogue 

 alluded to as a synonym of 0. auritus Erich., is as widely different 

 from that insect as one species of Onthophagus can possibly be 

 from another, and my 0. laviinatus, put down as a synonym of 

 0. capella Kirby, is very distinct from that species.

 Soc. N. 8. Wales, 1864, I., page 123. 



In my description of this species, I made the mistake of 

 describing as the male a female with the thoracic tubercles more 

 than usually large. The male has the thorax more retuse in 

 front than the female, and has a strong triangular horn in place 

 of the two tubercles of the female. 



342. — Onthophagus divaricatus. n. sp. 

 Length 4 lines. 

 Black, subopaque. Head, in the male with a transverse 

 raised line between the eyes, and two long rather slender and 

 slightly carved horns emanating from each extremity of that 

 line, extending in a direction upwards and outwards, and 

 obtusely pointed at their apex ; in the female with the frontal 

 transverse raised line rising* on each side from the upper angle of 

 the eye, and without horn or tubercle ; in both sexes, with the 

 clypeus rugosely and transversely punctured, with its suture raised 

 and semicirculai% and with the space behind the frontal trans- 

 verse ridge smooth and nitid. Thorax transverse, convex, opaque, 

 densely panctate, and presenting a granulated appearance, with, 

 the sides bulged out behind the middle, with a fovea near the 

 bulge, with the posterior angles emarginate, and without any trace 

 of the median line. The thorax of the male is less coarsely punctate
