272 DIPTERA NEMATOCERA. 



brown, trochanters ochreouR, femorn and tibiae brownish with 

 the tips slightly darkened, tarsi wholly pale ochreons. Wings 

 with a beantifnl pattei-n of dark and light bi-own. with narrow 

 lines, as shown in the figure. Halteres ochreons, knob some- 

 what darkened. 



Length of body 10 mm. ; wing 11 mm. 



Mt. Murud, head camp, November — 1 (j* (type) ; October — 

 1 cT. 



Nesopeza gracilis (de Meij.). 



Mt. Murud, head camp, October — 1 Q . 



Agrees with de Meijere's description and figure in most 

 respects but is rather larger (body and wing length 11 mm.). 



Nesopeza gracilis var. major vr. n. 



Differs from typical N. gracilis as follows : — ^Femora with 

 the tips only very indistinctly darkened. No trace of a dark 

 cloud over C7l^a. Size larger; body and wing-length about 14 

 mm . 



In the cf the cell M, is very long, with an extremely short 

 stalk. Hypopygium small ; ninth tergite with a pair of blunt 

 sub-lateral blackened processes, and a small sharp median black 

 tooth. Outer claspers very small and thumb-like, pale in 

 colour. 



Mt. Murud, 550O-ri3OO feet, November— 1 d*, 19 in cop. 



Nesopeza costalis var. horneensis sp. n. 



Differs from typical N. rostalif; Brun. (from S. India) as 

 follows : — Proboscis blackish. Wings without any trace of 

 darkening over Ctl^a or at the tips of anv of the veins on the 

 posterior margin of the wing. Length of body 10 mm. ; wing 

 9 mm. 



Mt. Penrissen, 4500 feet— 1 9 . 



Although much resembling A^ gracilis, N. costalis is cer- 

 tainly quite distinct on account of the much shorter cell M■^ 

 and the absence of dark markings on the pleurae. It is possible 

 that the Bornean form is really specifically distinct from the 

 Indian. 



DOLICHOPEZA PALLIDITHORAX de Meij . ? 



Mt. Penrissen, 3000 feet — 1 cT (immature). 



Alexander w^ould place this and allied species in Nesopeza, 

 on account of the rather long Rs, but it would seem to me better 

 confine Nesopeza to the species with ornate wings.
