first posterior cell closed and the proboscis nearly three times the 

 length of the body. 



Macquart in Ann. Soc. Entom. France, vi, p. 429, onl}' refers 

 to the species in a general article on the genus Pangonia. 



Roder, after some remarks on the descriptions given by other 

 authors, more especially by Wiedemann who probably did not 

 know this species, adds, from a specimen he had from Allahabad, 

 the following particulars : — 



The two first antennal joints are brownish black the third 

 quite black. The two first furnished on the upper and lower sides 

 with long black hairs. The long face is coverecl with yellow tomen 

 tum. Palpi yellow. Ocelli absent. The very long proboscis black, 

 but not two and a half inches long as Wiedemann gives, but only 

 I inch 7 lines ; my specimen is only 9 lines long. The beard on 

 cheeks and chin is long, yellow, but the forehead clothed with short 

 black hairs. The thorax has a brown ground colour, covered with 

 longer pale brown hairs, which are quite pale yellow on the lateral 

 borders and breast sides, so that two paler stripes thus appear on 

 the side borders. The scutellum is brown like the thorax and 

 with the same pubescence. The abdomen is reddish at the sides, 

 dark brown in the middle, the pubescence is more golden 3^ellow. 

 Under side of abdomen yellow, becoming brownish towards the 

 apex. The legs are wholty yellow. The first two joints of fore 

 tarsi are wider in a peculiar form, the tarsal joints of the fore legs 

 increasing in length. 



On the two hind pair the metatarsus is longer than the other 

 tarsal joints together, the legs have only very sparse yellow 

 pubescence. Wings tinged yellowish, the upper fork of the third 

 vein with an appendix. The first posterior cell is rather narrower 

 at its apex. Wings longer than the body. Halteres not so short 

 as Wiedemann gives, with a pale stalk and browner head. Roder, 

 vStett. Entom. Zeitg., xlii, p. 384. 



The males have the prolongation on fore tarsi as in some 

 African species. Roder mentions it. One or two of the females 

 have long bristles on these joints. The first posterior cell is closed 

 in some of the females with a short petiole. Two males, one of 

 which was wrongly labelled " amhoinensis, Fabr.," seem a variety 

 of this species, having no prolongation on the fore tarsi; the 

 third joint of antennae is bright red, not black. The yellow 

 colour on the abdomen is more prominent ; the face is shining and 

 dark, with hardly any greyish pubescence,

This species is easily recognized by the very long proboscis, 

 the first posterior cell of wing is usually open, though it varies 

 in degree, often being so very narrow that it appears closed at the 

 border, but is never pedunculated. The males mentioned above 

 as differing slightly from the typical form will belong to the sub- 

 species given below.
