Expanse of wings 0-100 x 0-030 ... 2-54x0-76 



Size of body 0-080 x 0015 ... 2-02x0-38 



Antennae rather slender, black, with a minute, very dense, pale 

 pubescence ; joints of the scapus sparsely haired ; flagellar joints 

 sub-sessile, 2 to 2^ times as long as broad. Palpi black or deep 

 brown. Eyes contiguous above. Head black, sub-nitidous. 

 Thorax black, sub-nitidous, with three longitudinal double 

 rows of short pale hairs, the intermediate one indistinct, 

 reaching to the middle of the thorax, the lateral ones run-

 the scutellum and the humeri ; scutellum with some long 

 hairs. Halteres deep brown, the stem paler brown, with appar-

 with a short pale pubescence ; lamellae of the ovipositor black, 

 oval. Legs obscure pitch-brown, the coxse almost black. In the

 mediate-legs the tibiae and tarsi are of almost equal length ; and 

 in the hind-legs the tibise are a very little longer than the tarsi. 

 Spurs as long as the fifth tarsal joint. First joint of the tarsi 

 about 2^ times the length of the second ; second joint almost J

 greyish-brown tint, the veins light umber-brown ; brilliant rosy 

 and blue margaritaceous reflections when viewed at a certain 

 obliquity. First longitudinal vein reaching the costa a short 

 distance before the base of the fork and a little beyond the tip of 

 the posterior branch of the fourth longitudinal vein ; petiole 

 considerably paler than the fork, and about equal in length to 

 the anterior branch ; branches running almost parallel, veiy 

 slightly divergent at their tips ; posterior branch very little 

 arcuated at the base, fg rather more than 2J times the length 

 of g?i ; M about ^ the length of Im.
