suture, nearly to the posterior margin. Scutelkim pale yellowish, 

 metanotum brownish. Abdomen brownish yellow, sides narrowly 

 black. Belly similar. Genitalia brownish yellow, of moderate 

 size, pubescent, consisting of a large fleshy subconical 1st joint 

 and'a 2nd much shorter, slender, hook-like joint with long stiff 

 black hairs on its underside. Leffs: coxce pale yellowish, re- 

 mainder o£ legs brown. Winxjs clear, very delicately iridescent. 

 Auxiliary vein ending just beyond half the distance between the 

 orio-in of the 2nd vein and the marginal cross-vein ; the 2nd vein 

 bemnning just before the middle of the wing, the praefurca being 

 two-fifths of the length of the vein ; marginal cross-vein exactly 

 ill middle of marginal cell, half-way between the tips of the 

 auxiliary and 1st veins ; the 3rd vein originating a little before 

 the marginal cross-vein, the basal portion distinctly elbowed ; 

 anterior w-oss-vein opposite marginal cross-vein, equal in length 

 to the basal side of the discal cell, which is open, coalescing with 

 the 2nd posterior cell ; posterior branch of the 4th vein forked 

 much before half its length, making the 3rd posterior cell nearly 

 elongate triangular ; posterior cross-vein in middle of wing, just 

 beyond origin of 2ud vein, thus making the 4th posterior cell 

 extraordinarily long. Halteres dirty white. 



Length 4 millim. . 



Described from a single male taken at Kurseong, Darpling 

 district, 29. vi. 10 {Annandale).

Genotype. According to Coquillett (1910) the species selected 

 as type is saxicola, Os. Sac, one of the original two ; but according 

 to Kertesz/s Catalogue of Diptera the name of the species should 

 be op(dizans, Os. Sac, with saxicola as a synonym. 



Head: eyes separated above by a narrow frons, below almost 

 contiguous. Proboscis cylindrical, moderately projecting; palpi 

 slender, rather prolonged, 1st joint elongate, 2nd and 3rd shorter, 

 3rd somewhat elongate. Antennae if bent backwards would not 

 reach the root of the wing; sixteen-jointed ; 1st scapal joint 

 short • flagellar joints subglobular, apical joint rather elongate, 

 the fliwellum bearing moderately short haii-s on the upperside and 

 somewhat close pubescence on the underside ; no distinct verticels.
