XI. DIPTERA. 



By E. Brunetti. 



(Plate vi). 



In view of the comparatively small number of species and 

 the insufficiency of our knowledge of Oriental Diptera, any attempt 

 to gauge the nature of the fauna of the Abor district must be little 

 more than surmise. 



Of eighty-five named species, including all the new ones (of 

 which several are known to occur outside the region collected over 

 by the expedition), 4 are found also in the Palaearctic Region, 16 

 in the Himalayan, 13 in Assam, 23 in the Indian plains, 7 in 

 Ceylon and 14 in the Malay Peninsula or East Indian Islands. 



Grouping them roughly into ''Temperate" species (Palae- 

 arctic and Himalayan together) as against ''Tropical" species 

 (all the remainder), there are 16 species which occur at least in 

 Himalayan localities (four occurring also in Palaearctic latitudes) 

 whilst about 30 species occur in one or more of the tropical 

 localities. 



MYCETOPHILIDAE. 



Leia arcuata, Brun. 



One specimen from Korasing, i-iii-12. 



In the Indian Museum from Darjiling, Kurseong and Naini 

 Tal. 



Allactoneura cincta, Meij. 



One specimen under bark in rotting wood, Kobo, 2-xii-ii. 

 A widely distributed species, occurring in Nepal, Sylhet, various 

 parts of India, Ceylon and Java. 



Sciara orientalis, Brun. 



Three specimens; Rotung, 24 and 25-xii-ir, and Dibrugarh, 

 17 — 19-xi-ii. 



Also a widely distributed species, in India, Ceylon, the 

 Himala3^as and Assam. 



Sciara, sp. 



Two specimens, too damaged to identify. The species falls in 

 the group with the ist longitudinal vein ending much before the 

 fork of the 4th vein, and with blackish thorax. One is from 

 Yembung (i3-i-i2), "in camp," the other from below Dosing 

 (1400 ft.), 29-i-i2, " under bark."
