Coleojjlerous Genus Oniticellus. 181 



The protliorax is transverse, rather strongly punctured and 

 lightly channelled along tlie middle. The elytra are sulcate, 

 with the interstices convex and finely irregularly punctured. 

 The pygidium and lower surface of the abdomen are opaque. 

 J . The head is armed with a transverse carina occupying 

 the whole width between the eyes, produced a little upwards 

 and outwards at each end and very obtusely toothed in the 

 middle. The protliorax is elevated into a broad hump, 

 nearly straight in front, but forming a blunt tubercle on each 

 side and with the anterior declivity smooth and nearly 

 perpendicular. There is a large rounded depression in each 

 front angle. 



? . The clypeus is more strongly and closely punctured, 

 there is a curved anterior carina and a nearly straight 

 posterior one. The prothorax has a slight blunt carina a 

 little behind the front margin. 



This species is allied to O.femoratus, Illig., but larger and 

 relatively broader, with the elytra less broadly and deeply 

 sulcate and the intervals broader and more opaque. In the 

 male the angles of the cephalic carina are much more pointed.

This species is black and moderately shining, with the 

 head and anterior part of the prothorax slightly metallic, and 

 the antenna?, the femora, the anterior angles of the pronotum, 

 the apical margins of the elytra, the pygidium and lower 

 surface of the body testaceous. The clypeus is very finely 

 punctured, the prothorax strongly and closely punctured and 

 longitudinally sulcate at the middle. The elytra are sub- 

 opaque and sulcate, with the interstices minutely and incon- 

 spicuously punctured and the alternate ones a little more 

 convex. 



<J . The head is armed with a broad carina, which is pro- 

 duced ^outwards at the angles, but nearly straight at the
