Eyes slightly contiguous ; occiput small ; frons narrow as viewed from above ; 
■face narrow, subglobular, fringed around with long hairs. 
Abdomen slender, tumid at the base, constricted markedly at the 3rd segment 
and from thence cylindrical till the end. Anal superior appendages long and 
slender, much longer than the 10th segment, inferior narrow and truncate, 
triangular. The dorsum of the 10th segment with a prominent carina. Oreillets 
robust. 
Wings moderately narrow, reticulation rather close ; trigones short, of ? to 4 
cells ; prearcuiar space entire ; cubital space and hypertrigones traversed ; /?•< 
bifurcated well before the stigma ; only a smgle row of cells between Rs and 
Rspl and between Miv and Mspl ; anal border markedly notched ; anal triangle 
of 3 cells ; membrane short and slender, not quite the length of the anal border. 
Superior appendages long and slender, longer than the 10th segment ; inferior 
short, truncate, triangular. Dentigerous plate of female subrounded, finely

Rec. Ind. Mus., Vol. xxii, p. 79, (1921). 
Male. Abdomen 40 mm. Hindwing 37 mm. 
Head. Eyes green, moderately contiguous ; labium olivaceous ; labrum, face 
and frons bright yellow, the latter which is raised into a fine point at its centre, 
smoky brown along the crest. The crest and borders of the face fringed with 
a ruff of long, black hairs. 
Prothorax brown. 
Thorax maroon brown marked with bright yellow as follows : — 2 antehumeral 
stripes on the front of dorsum, separated by the dorsal carina and lying parallel 
to one another, the interalar sinus, tergum and some small spots at the bases of 
the wings. Laterally two broad stripes, one of which lies between the humeral 
and first lateral suture and the other covers the whole of the metepimeron. 
Wings hyaline, stigma black, 3 cells in trigone of forewing, 4 in the hind, loop 
very small, of 4 cells, 4 cubital cells in forewing, 4 to 5 in the hind; nodal index: — 
^ ^ between Rs and Rspl ; 2 rows of cells between the 
bifurcation of Rs. 
Abdomen brownish black marked with yellow as follows : — 1st segment with 
a quadrate spot low down on the sides and a middorsal streak, 2nd segment 
with an apical, subtriangular spot low down on the sides and a middorsal streak 
Avhich gradually tapers apicaUy, the oreillets are also yellow, 3rd to 10th segments 
with a continuation of the fine, middorsal yellow line which broadens into a 
small triangle on either side the dorsal carina about the middle of the segments. 
In addition, there are on segments 3 to 9 lateral, subapical spots. 
Legs dark brown, the coxae and trochanters yellow and at the base of the mid 
pair this yellow is prolonged into the thorax for a short distance. 
Anal appendages long, sinuous and narrow, blackish brown. The inferior 
long, not quite half the length of the superior, narrow and triangular. 
Female very similar to the male, the abdomen being stouter at the base, not cons- 
tricted at the 3rd segment, the markings rather more pronounced. Anal 
appendages small, lanceolate, pointed. 
Dentigerous plate simple, prolonged into a spout-like structure, armed with 
about 8 small spines.
