than the median ; recurrent nervures received very near the 

 middle of the second and third cubital cells; cubitus of the 

 hind wing interstitial. Fore tarsi and hind tibiae almost 

 entirely unarmed; inner spur of the hind tibiae fully half as 

 long as the hind metatarsus ; tarsal ungues strongly bifid.

 Long. 18-20 mm. 



?. Very similar in structural details to contristans; the 

 antennae stout, more or less covered with very delicate silver 

 pubescence, which is also visible on the abdomen ; the dorsal 

 surface of the thorax rather less minutely punctured, giving 

 the appearance of very fine granulation ; mesopleuraa rugose. 

 Median segment, abdomen, and legs as in contristans. 

 Second abscissa of the radius almost twice as long as the 

 third. The first fuscous fascia of the fore wing runs along 

 the basal nervure, broadening rapidly from thecosta; the 

 second is very broad, filling the whole of the second and 

 third cubital cells, the radial cell except the extreme apex, 

 the apex of the first cubital cell, the apex of the first discoidal 

 cell, the second discoidal cell except the base, and the base 

 of the third discoidal cell.

Except in the very different colouring of the wings the 

 differences between this and contristans are very small.

? . Very similar in structure to the two last species, 

 differing in the following points: — Eyes nearer together on 

 the vertex, the posterior ocelli being half as far again from 

 each other as from the eyes; pronotutn fully as long as the 

 mesonotum, the sculpture of the thorax fine as in contristans; 

 pleurae sparsely punctured, the punctures large ; sides of the 

 median segment delicately striated, with sparse punctures ; 

 scutellum without a carina. The second fascia of the fore 

 wing is much narrower than in indocilis, occupying the radial
