23 Onthophagus triceratops, sp. nov. 



Niger, vel aeneoniger, ore antennisque ferrugineis, nitidus, sat 

 laevis, clypeo pronotoque minute et modice crebre punctatis, vertice 

 fere impunctato ; elytris fortiter punctato-striatis, interstitiis convexis, 

 parce et minutissime pundulatis ; pygidio distincte sat crebre punc- 

 tata : 



& , vertice late retrorsum produoto in laminam horizontalem 

 cujus margo postica medio paiilo, uirinque longe producta est, cornu- 

 bus duobus gracilibiis intus curvatis facientibus ; clypeo paulo producto, 

 reflexo, medio truiicato ; pronoto antice retuso handdentato. 



Long. 8 — 8'5 mm. Lat. max. 4'5 — 5 mm. 



Hab. N. E. Assam: Sadiya, 23-xi-i9ii. 



A male specimen of this species has long existed in the British 

 Museum and another was taken by Mr. Kemp with the two species 

 just previously mentioned. It is exceedingly like 0. luzonicus, 

 Lansb., but the elytral striae are rather coarsely punctured and the 

 interstices very finely, whereas in the Philippine form the scattered 

 punctures are more evident than those in the striae, which are 

 very fine. In the male of the Indian species the cephalic lamina 

 is a little produced in the middle between the horns, but in the 

 other it is straight or slightly emarginate there, and on the other 

 hand the prothorax is slightly prominent in the middle in the 

 Malayan, but not in the Indian form. 



24. Onthophagus sp. 



Kobo, 400 ft., 30-iii-i9i2. A single specimen of a minute 

 unknown species of this enormous genus. 



APHODIINAE. 

 25. Aphodius elcgans, All. 

 Yembung, iioo ft., 8 — 9-ii-i9i2. One specimen. 



26. Aphodius urostigma, Har. 



Sadiya, N, E. Assam, 23-xi-i9ii. 



This is an extremely common and widely distributed insect, 

 ranging from the Himalayas to Ceylon and also to China, Japan, 

 the Malayan Region and as far as east and south-east Africa. 



27. Aphodius chinensis, Har. 



Rotung, 1400 ft., 25-xii-i9ii. A single specimen was taken at 

 Hght. 



The species is common at Hong-Kong, but it is surprising to 

 find it ranging so far westward.
