Fig. 26. — Baccha amjjhithoe. Walk., wing. 



The above is the amalgamation of my description of Jiavo- 

 jnuictata (built up on a single $ in the Indian Museum from 

 Dibrugarh, Assam, 17-19. xi. 1911 (Kemp)) with Austen's descrip- 

 tion of Walker's amphithoe, with which species my species is, as 

 proved by examination, identical. Walker described the species 

 from a single headless specimen in the British Museum from Moul- 

 mein; whereas Austen's re-description is from several of both sexes. 

 Sibpur, Bengal, 4. iv. 1913 (Gravely); Calcutta (Graveli/); 8ukna, 

 Rungpo, Sikkim, 6. ix. 1909; Cherrapunji, Assam, 440U ft., 

 2-8 X. 1914 (Kemj)); Moulmein (Terburi/) • Kanthalai, 8. iii. 1892; 

 Kottawa, 2-1. iv. 1892 ; Trincomalee ; Galle (all Ceylon, Yerhuri/). 

 I surmise that pedkellata, Dol., vcsjxeformis, Dol., and yraliosa, 

 Big., are closely allied to amphWwe. 



Genus RHINOBACCHA, de Mevj. 



Rhinobaccha, de Meijere, Tijd. v. Eut. li, p. 315 1908). 



GEyoTYPE, R, r/racilis, de Meij. ; t. c. p. 316, d" ? , pi. viii, 

 fig. 38, head (profile). 



Body narrow. Eyes bare ; in c? not conspicuous, a little 

 wider apart in $ ; antenna) short, 3rd joint rather longer tiian 

 broad, arista bare. Epistome produced downward into a long 

 snout as in Ilhingia ; proboscis long, about IJ times height of 

 head in the type-species. Ahdomen narrow, only a little broader 

 at tip. Jlind femora not thickened, not spinose. Whtijs narrow, 

 alulse rudimentary ; cross-veins bent towards the wing-tip, nearly 

 parallel to the wing-border. 



This genus possesses some of the characters of liJiingia, Baccha 

 and Spher/ina : the epistome of the first, the venation of the second 

 and the rudimentary alulae of the third, and it has the basally 

 narrowed abdomen common to the two latter. From Ociip>la)nvs, 

 Sp<tthio(/asti'r and JJoros it is distinctly differentiated by the 

 prominent epistoma.
