Group Rhamphidiini. 



Rhamphidia nigriceps, sp. n. (Fig. 3, p. 356.) 



Head velvety blackish-brown, frons rather narrow, with a 

 small grey spot above the antennae. Antennae, proboscis, 

 and palpi brown. Proboscis a little longer than the head. 

 Antennae not much longer than the proboscis ; first five 

 flagellar joints roundish, remainder oval ; hairs about twice 

 as long as each joint. Thorax dark brown above, lighter 

 brown on the pleurae, without markings. Abdomen uni- 

 formly dark brown ; ovipositor lighter. Hypopygium, fig. 3. 

 Legs dark brown, the tarsi lighter apically. Wings nearly 

 hyaline, stigma rather faint. Venation : Sci continued far 

 beyond base of Rs, its tip much less distinct than Sc2 ; Rs 

 arising exactly in middle of wing-length ; cell R^ narrow in 

 apical third ; R^ and R2+3 ending in costa rather close 

 together ; R-M cross-vein present, situate about its own 

 length beyond the fork of Rs ; cell 1st Mj pentagonal, its 

 apical side shortest ; Cui meeting M just before or at the 

 base of the cell. Halteres brown. 



Length of body 4-5 mm. ; wing 5-6 mm. 



SiAM : Bukit Besar, 3 ($ (incl. type), 1 ? ; Talura, 

 18. i. 1901, 2 (J , 1 ? (Robinson Sf Annandale). 



Differs from R. kambangani in the blackish head and the 

 position of Cuj. 



Rhamphidia rufescens, sp. n. 



Head light grey ; proboscis, palpi, and scape of antennae 

 light reddish brown ; flagellum brownish, the basal joints 

 round, the rest oval, last three or four a little more elongate, 

 and with longer hairs, the hairs on the rest of the flagellum 

 being very short. Thorax and abdomen slightly shining, 

 uniformly light reddish-brown. Legs light brownish. Wings 

 transparent ; venation as in R. nigriceps. Halteres pale. 



Length of body 5 mm. ; wing 5-5 mm. 



Selangor : Bukit Kutu, Feb. 1903 [Dr. H. E. Durham), 



Evidently closely related to the preceding, but seems 

 distinct on account of its grey head, lighter colour^ and 

 slightly difi'erent antennae. It should be noted that the 

 specimen is somewhat immature. 



Gymnastes pictipennis, sp. n. (Fig. 4, p. 356.) 



Head yellowish, darker in the middle, rather thickly 

 covered with black hair ; frons very broad. Scape of
