Thorax small, cubical, coated with long hairs on the front and dorsal surface. 

 Legs long and slim, hind femora mth 2 rows of short, closely set spines on the 

 flexor surface, each ending in a single, long, distal spine, and a row of moderately 

 lone, fine hairs on each side of the distal end of the limb; mid femora with a row 

 of short, closely-set spines extending the Avhole length of the limb, fine spines 

 on the outer, extensor surfaces ; tibial spines long and numerous and an addi- 

 tional row on the flexor surface of the two anterior tibife ; claws bifid at the extre- 

 mities, the hooks being as long as the claws. 



Abdomen very similar in shape to that of EpojjJitkalmia, tumid at the base, 

 with auricles on the sides of the 2nd segment, 3rd to 6th segments well constricted 

 in the male, segments 7 to 10 dilated laterally and dorso-ventrally, the 10th 

 segment usually flexed strongly on the 9tli and bearing a strong dorsal spine 

 with, in some cases, 2 small, lateral spines. In the female the abdomen is of 

 more even width and markedly compressed laterally from the 3rd to the 10th 

 segments, the base of the abdomen is tumid and there is a strong carina to the 

 dorsum which is not well marked in the male. 



Anal appendages : superior short, diverging, pointed and bearing an external 

 spine on the outer border ; inferior triangular, very slightljr bifid at the extremity, 

 curving up to meet the superior. Superior appendages in the female very short, 

 conical and tapering. 



Genitalia : male orga^ns on the 2nd abdominal segment large and projecting 

 markedly from the ventral surface ; lamina usually depressed, elongated and 

 bifid at the free border ; hamules long, tapering, foliate processes, prolonged 

 into a long straight hook vv^hich is closel}^ ajjplied to the lobe ; lobe straight and 

 tapering to a point. 



Female : 8th abdominal segment not dilated ; Sth ventral plate prolonged into 

 tv/o oval or leaf -shaped processes which overlap the 9th ventral plate, the latter 

 being convex at its free border and not overlapping the 10th. 10th very short. 



Wings long and moderately narrow ; trigone of the forewing in Une with that 

 of the hind, broad, its costal and proximal sides subequal, the distal side being 

 the longest, its long axis in the breadth of the mng, entire ; trigone of the hind- 

 wing with its long axis in the length of the wing, entire, situated well distal to 

 the arc, its costal and distal sides subequal, the proximal much shorter than 

 either ; hypertrigone of the foremng usually traversed 3 times, that of the hind 

 only twice ; subtrigone in the forewing entire, its posterior angle projecting a 

 little posterior to the trigone ; arc between the 1st and 2nd antenodals, Avhich 

 number 13 to 16, the final being complete ; 4th nervure mth a single convex 

 curve ; multiple supplementary nervures to the bridge ; supplementary cubital 

 nervures to both wings, 4 or 5 in number ; 5a (Rspl) well formed, very long, run- 

 ning in some cases as far as the termen ; only 1 rov^' of cells between 5 and 5a 

 (Rs. and Rspl.) ; 7a (Mspl.) obsolete ; Sth nervure in the fore^Aing short and 

 stroiigly convex ; discoidal field widely dilated, 2 rows of cells as far as or beyond 

 the inner end of the bridge ; Sth nervure in the hindwing from the anal angle of 

 the trigone ; 9th nervure in the h'nd'ndng strongly angulated at about 2 or 3 cells 

 posterior to the trigone and gi^dng off a branch which forms the outer border of 

 the loop ; loop broad and short, usually 3 but sometimes 4 cells wide usually 

 made up of more cells in the female than in the male ; 3 rows of cells between 

 the loop and the membrane in the female, only 1 or 2 rows in the male ; tornus 

 markedlj^ angulated in the male, rounded in the female ; basal border of wing 

 markedly indented in the male, rounded or straight in the female. Membrane 

 large ; stigma of moderate dimensions, rather short.
