496 JOVRNAL, BOMBAY NATURAL HIST. SOCIETY, Vol. XXVII. 



Genitalia, Secondary ; lamina flat and depressed : hamules very tiny, the 

 external a slim, black pointed hook, the inner separated from it by a cm-ved 

 fissure, depressed and nearly quadrate; lobe higher than the hamules, projecting 

 and somewhat rightangled, coated with long black hairs. 



The female with a robust projecting scale ; border of segment not dilated ; 

 end of ventral plate broadly rounded, projecting and reaching nearly to the 

 end of the 9th ventral plate. 



Wings short, the hind with a broad anal field ; reticulation very open, so 

 much so that the trigone is apt to be lost in the general reticulation ; trigones 

 of the forewJng in line with that of the hind ; sectors of arc fused for a long dis- 

 tance in the forewing, the separation abrupt and widely divergent ; arc between 

 the 1st and 2nd antenodals ; 5 to 6 antenodals in the forewing, the final com- 

 plete ; trigone in the hindwing at the arc or a little distal ; 8th nervure (Cul) 

 in the hindwing and forewing widely separated from the anal angle of the trigone; 

 1 cubital nervure in the forewing, 1 or 2 in the hind ; the costal side of the 

 trigone in the forewing broken, the parts on either side of the fracture appro- 

 ximately equal or the proximal part the longer (the bend is usually about the 

 centre or a little distal to it) ; costal side of trigone in the hind straight or 

 bent, the bend then being ftirther distal ; all trigones, hypertrigones and sub- 

 trigones in the forewing free ; no accessory nervures to the bridge ; 1 row of 

 cells between 5 and 5a (Rs and Rspl), the latter, imperfectly developed ; 

 8th (Cul) ner\Tare in the forewing moderately curved ; the discoidal field with 

 I row of cells at the beginning, dilated at the termen ; no distinctly formed 

 loop in the hindwing ; stigma small and the membrane very small. 



This genus should have been included in the fourth group, following imme- 

 diately after Palpopleura and before Bmcliydiplax and is easily distinguished 

 by the broken costal side of the trigone in the forewing and by the separation of 

 the 8th nervure from the anal angle of the trigone, only 5 to 6 antenodals and 

 the discoidal field with but a single row of cells at its commencement. The 

 small size and the very open reticulation of the wings is another guide.

 cJ Bright carmine red ; the labium, labrum (which has yeUow spots at its mid- 

 dle), a narrow basal line to the forehead, the prothorax, the dorsum of the 

 thorax, the underside of the thorax in its fore half and a moderately broad band 

 on the sides black. 



Specimens in the British Museum have the face yellow, the eyes with a red 

 cap to their summit, the vesicle and occiput oHvaceous and the sides of the 

 thorax yellow. • 



Abdomen bright red in the adult or ochreous in teneral specimens, with a 

 small comma-hke mark on each segment. The 8th segment black on tha dorsum. 

 Anal appendages red or yellow, the superior short and shm, the inferior mode- 

 rately broad and of the same length as the superior. Legs entirely black.
