Mesonotal praescutum shiiiy with faint metallic reflexions, the 

 median area back to the suture pale; lateral stripes dark brown, 

 confluent with the dark- brown remainder of the mesonotum; the 

 pale colour of the anterior part of the praescutum may be abnormal 

 as this region of the thorax appears to be quite hollowed out inside. 

 Pleura yeUow with a very broad and conspicuous dark- brown 

 longitudinal stripe, beginning dorsad of the fore coxa, passing 

 caudad to the abdomen; mesosternum abruptly yellow, Halteres 

 yellow, the knobs conspicuously dark browTi. Legs with the 

 coxae and trochanters yellow; femora greenish yellow, the tips 

 indistmctly darkened; tibiae pale brown; tarsi pale brown, the 

 terminal tarsal segments conspicuously paler, on the posterior legs 

 beyond the metatarsi light cream-colour; posterior metatarsi very 

 broad and flattened ; claws small, each with five basal teeth which 

 decrease in size basad. Wings broad, subspathulate, the base 

 strongly petiolate; membrane strongly infumed, conspicuously 

 variegated with dark brown and subhyaline; the subhyaline areas 

 include most of ceUs C, Sc, Scl, R and 1st Rl ; small brown clouds 

 at arculus, at the supernumerary cross- vein in cell Sc, at origin of 

 Rs and at the stigma, the latter small, oval; the second brown 

 area is confluent behind with the ground-colour; the third area 

 is connected with the ground-colour by a narrow seam along Rs; 

 the subhyaline areas thus appear as conspicuous blotches in cells 

 Scl, R, and 1st Rl; base of wing pale; veins dark brown, yellow 

 in the subhyaline areas. Venation : Sc rather short, ending about 

 opposite one-fourth the length of Rs, Sc2 not far removed from tip 

 of aS'cI ; Rs of moderate length, almost straight but very oblique 

 in position so cell 1st Rl is greatly widened at its proximal end; 

 r at tip of Rl ; r—m short, about one-half m; cell 1st M2 elongate- 

 rectangular, gently widened distally, the vems beyond it short, 

 Cul beyond it being about equal to the basal deflection of Cul, 

 the latter at the fork of M. 



Abdominal tergites dark brown; sternites light yellow, the 

 caudal margins of the segments narrowly darkened.
