JJo, 5,] Parasitic Muscidce from British India. 11 



foot-claws and pulvilll on the contrary that it should be a female, I 

 know another species from Java {Crossocosmia curvipalpis) which I intend 

 to describe in Volume XXXVI of the Dutch " Tijdschrip voor Entomo- 

 logie/^ and which shows the same combination of sexual characters. It 

 stands in the nearest relation with the above described 6V. biseriata, 

 but this latter differs from it in having a more prominent front^ in the 

 frontal bristles being more regularly arranged in a double row on each 

 side, in narrower black hind borders of the abdominal segments, and in 

 the apical cross-vein which is more concave. 



3. Tricholyga tombycisy Becher. 

 Becher, Indian Museum Notes, I, p. 77, pi. V, fig. ]. 

 Of this Tachiuid fly the Trustees of the Indian Museum at Calcutta 

 have sent to me for examination two typical specimens, a male bred from 

 Attactis ricini, Boisd., and a female, bred from the mulberry silkworm. 

 Two other specimens (both females) in the same collection from 

 Calcutta were not determinated, but proved to belong to the same 

 species; they were indicated to be parasitic, the one on Olene mendosa, 

 Hbn., the other on DasycMra thwaitesii, Moore. 



Tr. hombycis seems to be a not uncommon insect in British India, as 

 Becher has had several specimens of it. It also results from the fore- 

 going remarks, that it attacks very different species of Bombycid 

 Lepidoptera. 



A species, which is said to be related to Tr. hombycis, deposits its 

 eggs upon locusts [Acridium peregrinum, Oliv.) : see Indian Museum 

 JSotes, IV, p. 33.
