from the PlnUppine Islands. 99 



Tahanus Iscion n. sp. $. Dark brown, abdomen and legs 

 black; wings broivn; the tip and a part of the discal cell, hyaline. 

 Length: 15 — 15 mm. 



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

 from above; the division between the 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 

 side very shallow. Thorax dark brown, with black pile, especially on 

 the pleurae; abdomen black, shining; legs black; halteres with a yellow 

 knob. Wings brown, axillary angle paler; apex hyaline within the 

 second submarginal cell, the proximal half of which is brown, a hyaline 

 spot in the middle of the discal cell, both ends of which are brown; 

 on both sides of that hyaline spot the brown ground color of the wing 

 is somewhat yellowish; first posterior cell open, although somewhat 

 coarctate towards the tip; no stump of a vein. — Two males. 



Stratiorayidae. 



Mosapha bicolor (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. 



NegritoTYiyia maculipennis (Ephippium maculip, Macq. 

 D. E. IV, 54, Manilla). A dozen (g 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 hind tarsi are black or dark brown; the description of 

 the pattern of the thorax disagrees etc. Three specimens. 



Sargus 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.
