258 JOURNAL, BOMBAY NATURAL HLST. SOCIETY, Vol. XXVII. 



Prothorax with a very small posterior lobe, the free border of which is 

 slightly fissured. 



Thorax robust, deep and long. Legs robust, long, hind femora with a row 

 of widely set, gradually lengthening spines, mid femora with a similar row 

 of rather longer spines, tibial hairs fine and numerous, claw-hooks robust, 

 situated about the middle of claws. Armature of the female very similar. 



Abdomen short but very robust, flattened from side to side and strongly, 

 dorso-ventrally dilated at the base tapering gradually to the anal end. 



Wings long and broad, mainnervures very massive, reticulation very close, 

 due largely to a development of secondary neuration, trigone in the fore- 

 wing about 2 cells breadth distal to the line of the trigone in the hind, its 

 costal side lengthened ; traversed many times, its relation to the hyper- 

 trigone about a right angle, trigone in the hindwing traversed several 

 times, its distal side strongly concave, situated at the arc, hypertrigone in 

 the forewing traversed several times ; in the hind, usually only once, sub- 

 trigone in the forewing prolonged proximally, traversed many times, 

 sectors of the arc separated, but running close together for a considerable 

 distance, arc between the 1st and 2nd antenodal nervures, 8th nervure in 

 the hindwing at the anal angle of trigone, antenodal nervures very 

 numerous, from 24 to 30, final antenodal, complete or incomplete, 4th 

 nervure undulated more or less, the end steeply curved towards the termen, 

 1 to 4 rows of cells between 5 and 5a, 2 cubital nervures in the hindwing, 

 1 to 6 in fore, numerous supplementary nervures to the bridge, 8th nervure 

 in the forewing variable, either flat or moderately curved, discoidal field vari- 

 able, commencing with 2 or 3 up to many cells, either contracted or dilated 

 at the termen, anal field very broad, loop long and narrow, the middle 

 nervure very obtusely angled, nearly straight, filled with a close a reticula- 

 tion, the anal field filled with a close reticulation of secondary nervures, 

 the cells rrangedin transverse rows. Stigma large, membrane large. 



Sexual organs of male very small, tentaculse with internal and external 

 tentaculse. For details, see under species. Of the female, border of 8th 

 segment not dilated, vulvar scale very small.
