Antennfe Sjointed, those of the male produced into projecting 

 horns on the outer extremity in the middle of 4th-7th joints. 

 Head narrow, eyes large, ocelli in centre of the forehead. Legs 

 long and slender, all bearing spines, those on the hind tibia? large 

 and straight; claws bifid. Wings: forewings with thick costal 

 nervure and large rounded stigma, the costal nervure extending 

 bej'-ond the tip of the radial cell, but not forming an appendicular 

 cell ; marginal nervure turning upward ; the first of the four 

 cubital cells small, second and third angular, longer than broad, 

 with the transverse cubital nervures marked with foveas in the 

 middle; third discordal cell petiolate; no lanceolate cell: hind- 

 wings with costal nervure straight; radial cell petiolate at the tip, 

 median cell large, transverse, cubital nervures showing fovese in 

 centre; first cubital cell small, cubital and discoidal nervure not 

 reaching the outer margin of the wing. Body long and slender, 

 the saw of the female projecting beyond the abdomen. LarA'a 

 flattened, slendei', with six thoracic legs. 



This genus belongs to the Sub-family Pteryijophorince, " the 

 members of which have no lanceolate cell in the forewings, and 

 the accessory nervure of the hindwings is wanting, the latter 

 have only one middle cellule, and the anterior are appendiculated" 

 ( Ashmead). The genus Pterygophorus is typical of the group, and 

 to it the genus now proposed is allied in the general form of 

 the wings, but the latter has the scutellum postei'iorly rounded. 

 The larva, both in form and habits, is very different from any 

 member of the group known to me.
