520 Mr. C. O. Watcrhouse on new 



elytra brown. I have seen this species bearing the name 

 C. malaccensis, but believe it to be undescribcd. 



Copris sijnatus, Walker. 



This appears to be a common Ceylonese species, easily 

 recognized by the two erect horns on the margin of the head 

 and by the T-formed horn on the vertex. 



It is redescribed by Harold under the name of CaiharsiUB 

 coronatus (MT. Mimchen ent. Verein, i. p. 98). It is 

 allied to Copris punctulatus, Wiedem.

I lab. Malabar, Nilgiris (W. Davison, Esq.). 



Very near to C. signalus, Walker, but a little narrower. 



The male is at once distinguished by the singular arma- 

 ture of the head. The thorax is not quite so coarsely punc- 

 tured as in C. signatus, and in the larger male the punctures 

 have a tendency to run together in a longitudinal direction. 

 In the large male there is a slight indication of a double 

 swelling at the anterior part of the dink. The elytra have 

 the stria; very distinct, the punctures moderately strong and 

 somewhat separated ; in the larger males they encroach more 

 on the interstices and appear like pairs of punctures (one <m 

 each side of the stria) united on the stria ; the interstices are 



moderately convex, very distinctly punctured, the punctures 

 separated from each other by about two diameters of a 

 puncture. 



The female differs from the female, of 0. BtffnattU in being 

 a trifle narrower, with rather more finely punctured thorax ; 

 the head with the two anterior teeth a little narrower and 

 separated by a narrower triangular space ; the frontal tubercle 

 having a tendency to be binodose at the apex. 



1 have seen this species bearing tin; manuscript name C. 

 rhinocerus.
