Cylindical, very smooth and shining. The head is smooth, 

 the median liorn abru])tly elevated at the vertex, compressed, 

 produced forward ancl ui)\vard, rugose ami feebly grooved on 

 the posterior surface, transversely wrinkled on the anterior 

 face, dilated a little towards the end and forked. Canthus 

 produced laterally and more or less pointed, and the supra- 

 orbital ridge produced to a point in front. The erect mandi- 

 bular process is as long as the frontal horn, triangular in section, 

 and very bluntly pointed. The pronotum is a little shorter 

 than its width and very smooth, without punctures except in 

 the deep marginal grooves and the oblitjue lateral scar. The 

 elytra are very deeply sulcate, with conspicuous ])unctures in 

 the grooves and the intervals strongly convex. The meta- 

 sternum is very smooth, but the anterior angles are evenly 

 punctured and there is a narrow rugose lateral band.

Type in the Hope Dept., Oxford University Museum. 



Although the following form is usually distinguished easily 

 by the narrow uncleft frontal horn, eertam specimens from 

 Assam seem to form a complete transition, and I therefore 

 regard it as a variety of C. fronticornis. 



142. Ceracupes fronticornis, var. austeni. 



Ceracupes austeni Stoliczka, Journ. Asiat. Soc. Bengal, xlii, 2, 1873, 

 p. 151 ; Gravely, Mem. Ind. Mus. iii, 1914, p. 212, pi. 11, fig. 11. 



This variety is like the typical form, but the cephalic horn is 

 narrow, tapering anteriorly and bluntly pointed at the end 

 instead of being bifurcated. The pronotum, in addition to the 

 punctures in the marginal grooves and lateral scars, has a few 

 scattered punctures on each side near the scars, and the 

 punctures in the elytral grooves are generally a little larger 

 than those of typical specimens. 



Length, 21 to 27 mm. ; breadth, 7-5 to 9 mm.
