258 DIPTERA NEMATOCERA. 



almost as in E. fuscomarginata End., but Rs rather shorter 

 and more bent, and the tip oi An much further from the tip 

 of Cu^. Halteres pale; base of knob dark. 



Length of body 7 mm. ; 6.5 mm. 



Mt. DuUt, 3000 feet, January— 1 o*. 



An immature female Mt. Murud, 5500—6300 feet is probably 

 referable to this species, but differs in the absence of the 

 yellow bands on the abdomen, and the distinctly separated 

 eyes. The new form is close to E. aurantia (Brun.) and E. 

 fuscomarginata End., differing from the former in the colour of 

 the abdomen, from the latter in the venation, and from both 

 in the black instead of yellow head. In E. aurantia the front 

 is distinctly broader than it is in the supposed female of E. nig- 

 riceps. 



Another female in the collection of the Malay States Museum 

 from Peninsular Siam is certainly the same species, although 

 the dorsum of tlie thorax is somewhat darkened.
