Sei/chelies and Rangoon. 13 



Proslernnm formed rather as in S'lciutn picanltiannm^ very 

 sliort, forminor only a very narrow bridge in trout o£ each 

 coxa, and sloping steeply upwards («'. e., dorsalwards) in the 

 middle in front^ not forming a median keel. The balsam- 

 preparation of the mouth-parts shows that ih^meidum (fig. 9) 

 is broader than long (contrast S. picanUianum) . 



No species which I have seen is closely like this. The 

 Hawaiian S. anffiislirolle, Scott (1908, p. ilG), resembles it 

 in its minute size and general colour-scheme — red thorax and 

 black elytra. But S. angusticolle is distinctly though finely 

 punctured and pubescent above, and is proportionately longer 

 and narrower, less oval in outline, and with elytra less 

 broadened about the middle. 



Loc, Heychelles : Siliiouette, 1908. 



Fifteen examples, all from the high endemic forest above 

 Mare aux CJochons, well over 1000 feet. 



Named after the Abbe Rochon, a member of du Roslan's 

 expedition in 1769; he left a written record, and his name 

 has been given to a river in Mahe. 



Arthrolips, Wollaston. 



The material includes three species — A . flavicolUs, Matth., 

 hitherto known from Java, an example of which is now 

 recorded from Rangoon; A. insiilce-longce, sp. n., from the 

 Seychelles ; and an undetermined species from the Seychelles. 

 Since the appearance of Matthews's Monograph, Fauvel 

 (1903) has described three new species from New Caledonia, 

 and Reitter (1908) two new species from East Africa. But 

 those before me do not appear to be identical with any of 

 these.

 Loc. Rangoon; from nest of Mania striata, 9. x. 1911
