520 Mr. C. 0. Waterhouse on new 



elytra brown. I have seen this species bearing the name 

 C. maJaccensisj but believe it to be undescribed. 



Copris signatus, 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 Catharsius 

 coronatus (j\lT. Miinchen ent. Verein, i. p. 98). It is 

 allied to Copris punctulatus, Wiedem.

Statura C. punctulati, piceus, subojiacus ; capita Iscxi, vertice angn- 



lisque posticis pnnctulatis ; thorace creberrime punctato ; elytris

distiucte punctatis. 

 (5' . Capite antice sicut tnincato, margine medio cornu erecto, acu- 



minato, ad apieem paullo curvato, froute medio cornu erecto 



parallelo ad apieem binodoso. 

 <J , var. minor. Capitis cornu anteriori minori ad basin antice 



utriuque dente porrecto instructo.

apieem subbinodoso. 

 Long. 6-6| lin. 



Hah. Malabar, Nilgiris ( W. Davison, Esq.). 



Very near to C. signatus^ 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 disk. The elytra have 

 the striae 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 on 

 each side of the stria) united on the stria ; tlie 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 C. signafus 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. 



I have seen this species bearing the manuscript name C. 

 rhinocerns.
