Seychelles and Rangoon. 13 



Proslernnm formed rather as in Sncvim picaultiannm^ very 

 short, forming only a very narrow bridge in front of each 

 coxa, and sloping steeply upwards {i. e., dorsalwards) in the 

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

 preparation of the mouth-parts shows that ilia mentiim (fig. 9) 

 is broader than long (contrast S. picaulttanum) . 



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

 Hawaiian S. anguslicolle, Scott (1908, p. 416), resembles it 

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

 black elytra. But 8. angusticolle is distinctly though finely 

 punctnred and pubescent above, and is proportionately longer 

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

 broadened about the middle. 



Log. Seychelles : Silhouette, 1908. 



Fifteen examples, all from the high endemic forest above 

 Mare aux Cochons, 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 mateiial includes three species — A . flavicolUs, Matth., 

 hitherto known from Java, an example of which is now 

 recorded from Rangoon ; A. insulce-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 mc do not appear to be identical with any of 

 these. 



5. Arthroh'ps Jlavicolh's, Matthews. 



Arthrolips Jlavicollis, Matthews, Ann. & Mag. Nat. Hist. (5) vol. xis. 

 1887, p. 107 ; Mon. CoryiophidEe, p, 92. 



One example, agreeing closely with the type. 

 Lac. Rangoon; from nest of Miinia striata, 9. x. 1911 

 (Dr. H. II. MarshalV). Previously recorded from Java. 



6. Arthrolips insulce-longcej sp. n. 

 (PI. I. figs. 10, 11.) 



Sat breviter ovalis, convexus, nitidiis, castaneus, fere unicolor, sed 

 elytris ad latera et antice ad sutiiram indisbincte infuscatis, pedi- 

 bua antenuisque castaneis, harum clavis baud nigricantibus ; 

 corpore supra subtusqiie dense punctate, pallide pubesceute. 



Long. Corp. 1-15-1-25 mm.
