2. Ceracupes ArsTENi, n. sp. 



This species possesses all the characteristics of the genus, as given by 

 Kaup. Total length 22 m.m., width of head 4'8, of prothorax 6"6, of wings 

 at the shoulders 6*8, length of elytra 12*3 m.m. 



In general structure it is very like C. fronticornis, but the clypeus-horn 

 is obtusely rounded at the end, not emarginated, the upper concave edge is 

 punctated, longer and narrower than in that species. The processes on the 

 jaws are posteriorly flattened and rugosely striated, anteriorly convex and 

 smooth. The lateral scar of the prothorax forms a punctated S. Scutellum 

 smooth, waist at the sides densely punctated. 



The furrows of the wings are coarsely punctated, without any percepti- 

 ble hair. The metasternum is convex, generally smooth, only along lateral 

 margins finely punctated. The median tibise have externally two spines, the 

 posterior ones only an indication of a small point. 



Hah. — Naga hills. North Eastern districts of Bengal. Major H. H. 

 Godwin- Austen found a couple of specimens at an elevation of 6000 feet. 



I have never received G. fronticornis from any of these districts. It 

 must come from the Chinese portion of eastern Tibet, for western Tibet has 

 no forests, 



3. CoMACFPES CTLiNDBACErs, Perty. 



Hah. Johore, at the southern end of the Malay Peninsula. One specimen 

 measures : total length 26*4 m.m., width of clypeus 5*5, (Kaup gives 7 m.m.) 

 width of prothorax 8, (Kaup gives 9), length of elytra 14*9 m.m., (Kaup 

 gives 25^, which is clearly a mistake for 15*5 m.m.). 



Kaup's specimens from Malacca appear to have had a much broader 

 clypeus and prothorax, but the two Johore specimens which I examined 

 agree with the description of the species in every other detail. 



4. CoMACUPES Masoni, n. sp. 



Total length 30.5 m.m., width of clypeus 6*4<, of prothorax, or 

 shoulders, 9*1, length of elytra 16.75 m.m. 



Kesembles G. hasalis, but is much more slender ; upper lip with the 

 front surface sloping, but scarcely indented at the edge ; densely hairy. 

 Clypeus densely punctated and shortly hairy, except in front of the horn, 

 which is large, compressed, strongly projecting in front and very slightly 

 elevated, with an obtuse end sharpened from below, its posterior end is almost 

 vertical without a free point, the upper ridge is obtusely rounded, except 

 for a short distance along the middle which is concave and rugose. 

 Prothorax with the lateral scar small, smooth, with a little dot in front of 

 it, as in G. cylindraceus, but in the present species the marginal furrow is 

 in front near the corner almost angularly bent in. The furrows on the 

 wings are slightly more coarsely punctated, than in the last species.
