the black ; the black spot in front of the thorax is sometimes 

 wanting. 



I have specimens from the Philippines (Prof. C. Semper), 

 which differ in having the brown stigma separated from the 

 subapical brown cloud, by a broad hyaline interval ; the inter- 

 mediate pair of spines on the scutellum is comparatively smal- 

 ler; but I do not perceive any other differences. M."^ Bigot's 

 description applies to these specimens. M.^ Walker recognized his 

 R. hahilis in them ; they may nevertheless be a difi'erent species. 



NB. Rosapha is easily distinguished from Tinda : 



The antennae are comparatively longer ; the elongated last 

 joint has a distinct, although very short, fringe of microscopic 

 hairs on both sides (as in Hermetid) ; in Tinda a similar , but 

 much less distinct fringe is perceptible on one side only. 



The thorax is a little more narrowed anteriorly ; in Tinda, 

 its sides are nearly parallel. 



The four scutellar spines are much longer and stouter here 

 and the intermediate pair is much larger than the lateral ones. 

 In the specimen from Celebes the intermediate pair , in conse- 

 quence of its size, overshadows entirely the much smaller late- 

 ral pair ; it is not quite so large , however , in the specimens 

 from the Philippines. In Tinda , the four spines are short , of 

 about egual length and the hind margin of the scutellum is 

 marked off by a distinct groove. 



The anterior crossvein is quite distinct , and hence , the pro- 

 ximal end of the first basal cell square ; in Tinda it forms a 

 point, in consequence of the absence of the small crossvein ; in 

 other respects the venation shows but little difference. 



The c/ has the eyes contiguous for a considerable space above 

 the antennae ; in the 9 they are separated by a moderately 

 broad front (broader above than below).

 Nine c/", one 9 ; Kandari, Celebes, April 1874 (Beccari). 

 The description agrees quite well.
