Coelostoma stultum, Walker. 



One specimen (No. 4145/19) measuring 4IX2J mm. from 

 Dibrugarb, N.-K. A«sam, I7-I9'xi'i9ii {Kemp), differs from the 

 normal C. stultum from India, Indo-China, Java and Borneo, in the 

 punctuation of the upper surface being finer and less dense and in 

 the femora and epipleura being rather black and not as usual 

 of a verj' obscure red. The ventral segments are conspicuousl}'' 

 red-spotted on the sides. Otherwise it has the narrow scutellum 

 and long tarsi of C. stultum and the first joint of the intermediate 

 tarsi is also much more elongate than the second. It is perhaps 

 a slight variety of that wide-spread species. 



Coelostoma horni, Regimbart. 



Under stones on the bank of the Dihang River, Janakmukh, 

 i7-xii'i9ii (600 feet), one specimen was found (No. 4152/19) 

 with the sides of the elytra more coarsely punctured than is 

 usually the case in individuals examined from Ceylon. 



I have ascertained myself by comparison with the type in the 

 Paris Museum that the species is a good one, at least not the same 

 as C. orbiculare F. It belongs to an aberrant and hitherto un- 

 noticed series, of which there are more, with the intermediate 

 femora very densely and closely clothed beneath with silky hairs 

 (not disjoined setae and brilliant interspaces as in C. orbiculare), Qrst 

 ventral segment carinate and prosternai process toothed anteriorly. 

 The claws of the tarsi have a tooth-like process on the base. Nei- 

 ther of ihes^ important characters were noted in the original 

 description, the specimen having apparently not been examined 

 from the ventral side, as it was glued to cardboard. Otherwise, 

 and superficially, C. horni is very Uke C. stultum, but smaller, 

 having also the maxillary palpi of a clear yellow colour. 



Dactylosternum hydrophiloides, MacLeay. 



Dr. Kemp has obtained a good series of this pretty common 

 Indo-Malayan species at Rotung (1400 feet), 28-xii-i9ii, under 

 bark (Nos. 2592-2605/19), and one example (No. 2606/19) at vSadiya, 

 N.-E. Assam, 27*xi-i9ii, under a dead plantain tree.
