Legs. — Black, with microscopic whitish pubescence, all the 

 tarsi wholly yellowish except the extreme tips. 



Wings. — Clear, veins and the region of the stigma yellowish ; 

 halteres apple green.

Tinda indica, Walk. 



One cf, Dibrugarh, 17 — 19-xiii. A not unconnnon and 

 rather widely distributed species, occurring in India, Assam, 

 Celebes and Manila. 



TAB AN I DAE. 



Chrysops ? designata, Ricardo. 



Two 9 2 of a species of this genus agree fairly closely with 

 Miss Ricardo's designata, and may be a varietal form of it. It 

 was described from specimens from Naini Tal, Nepal and Yunnan. 



ASIUDAE. 



Of this family only four specimens are present. Two are not 

 in sufficiently good condition for identification, one belonging 

 to the Dasypogoninae , the other to the Asilinae : both from 

 Sadiya, taken respectively 23-xi-ii and 28-xi-ii. The remaining 

 two specimens are in good condition, representing Asilns (sensu 

 lato), coming respectively from Kalek (3200 ft) (i9-iii-i2), and 

 Dibrugarh, 17 — 19-xi-ii. In view of the large number of species of 

 this group described from the East and the extreme difficulty of 

 differentiating the species, any attempt at identification would be 

 little better than conjecture. 



DOLICHOPIDAE. 



Six specimens are present belonging to this family, but identi- 

 fication is practically impossible, from the indifferent condition of 

 most of them, and the fact that they are mostly females. More- 

 over, until the Oriental species already described are placed upon a 

 firm foundation, it would be hazardous in the extreme to encum- 

 ber the catalogue with further names. One is a Psilopns,' of 

 which over seventy species have been described from the East, 

 mostly from single specimens, the types of which are now probably 

 in greater part unrecognizable or completely lost. 



SYRPHIDAE. 



Paragus rufiventris, mihi, sp. nov. 



cr* Assam, Western Himalayas, Ceylon. Long. 3 mm. 



Head. — Frons shining black, almost bare. Eyes subcontiguous 



only, and for a very short distance ; posterior orbit of eyes with a 



1 Aldiich, the leading expert in North America in this family, has shewn that 

 the use of this name by Poda previously was not in a zoological sense, and there 

 tore its abandonment in favour of Agonosoma is unjustifiable.
