Palpi and face dark-brown, with some black pile; head ($) flattened 

 from above; the division between tbe large and the small facets very 

 distinct, Antennae dark brown or reddish-brown; third Joint long and 

 narrow; its upper angle projecting squarely; the excision of its upper

Stratiomyidae. 



Rosapha hicolor (Calochaetis bicolor Bigot, Ann. S. Ent. 

 Fr. 1879, 189, Manilla). I have already said about the specimens 

 (Enumeration etc. p. 26) from the Philippines that they differ from 

 R. habilis Walker (Celebes) in having the brown stigma separated 

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

 mediate pair of spines of the scutellum is comparatively smaller. They 

 may be a different species. 



Negritomyia maculipennis (Ephippium maculip, Macq. 

 D. E. IV. 54, Manilla). A dozen ( $ Q ) specimens. Seems to be 

 a common and wide-spread species; the abdomen is more distinctly 

 bluish than it was in the specimens from Ternate and New- Guinea 

 mentioned by me in the Enumeration etc. p. 23. 



Acanthina azurea (Gerstaecker, Linn. Ent. XI, 334; Ceylon)? 

 I am very doubtful about the determination of this species, as the 

 description disagrees in several points. The Vertex is black, not reddish; 

 the front and bind tarsi are black or dark brown; the description of 

 the pattern of the thorax disagrees etc. Three specimens. 



Sarg US spec. One specimen. Closely related to, if not iden- 

 tical with the species from Celebes which, in the Enumeration (p. 28) 

 I called remeans Walk, with a doubt. Frontal triangle, face and 

 antennae are more reddish; the front tibiae paler, the scutellum more 

 bluish etc.
