■streak on either side of the fiont, broad above, tapering anteriorly. Laterally 
two broad stripes of the same colour, the first a little interrupted above at its 
npper comer, the second covering the whole of the metepimeron and just 
separated from a small spot of green at the base of the hindwing. 
Legs blackish brown, the coxae yellow, long and rather slim. 
Wings hyaline, rather broad ; stigma black, moderately short and usually 
braced, that of fore-ning distinctly larger than that of the hind ; trigones very 
variable, that of forewing with 3 to 5 cells, that of the hind with 3 or 4 cells ; 
loop with 5 cells ; 2 rows of cells between the forking of i?s ; 7 to 8 cubital nervures 
in the forewing, 6 in the hind ; hvpertrigones traversed 3 times in all rvings ; re -

ticulation rather close ; nodal index : — 
anal triangle with 3 cells.

membrane small, white. 
Abdomen long and slim, tumid at the base, constricted at the third segment, 
dark brown marked with green and yellow as follows : — 1st segment broadly 
greenish j^ellow on the sides, a doraal, green triangle at the base and an apical, 
oval spot of the same colour ; 2nd segment with the sides broadly yellowish green 
and the dorsum with 2 transverse, wedge-shaped spots about the middle, separat- 
ed by the dorsal crest, a basal irregular spot of green and an apical streak of the 
same colour on the dorsal carina w'hich is united wdth an apical, yellow annule ; 
3rd segment with the basal half of the dorsal carina yellow and a lateral, basal 
triangle of yellow at its centre, 2 transverse, yellow spots ; 4th to 7th segments 
with the same central, yellow, transverse spots and apical annules of yellow ; 
8th and 9th segments with only the apical annules ; 10th segment with only a 
lateral, yellow spot. 
Anal appendages dark brown, the superior with a prominent mid-rib, narrow 
at the base, broadening spatulatewise after the first third, the apex bevelled, 
pointed as seen in profile, the upper surface near the apical end furnished with 
long, stiff hairs, the inferior about two -thirds the length of the superior, trian- 
gular, curling upwards. 
Female. Length of abdomen 47-49 mm., hindwing 40-42 mm. 
Head : Labrum bright ochreous, rest of face, labium and frons olivaceous 
as in the male ; occiput black. Face as in the male, is fringed with a margin of 
long, stiff, black hairs. 
Rest of thorax and abdomen very much as for the male, the sides of the 2nd 
segment are less broadly yellow, the sides of the 3rd are more extensively so, 
reaching as far as the apex, this colour also extends along the sides of the 4th 
and 5th segments and there is a trace of it on the 6th and 7th, the sides of the 
8th to 10th being broadly yellow. 
The other markings are as in the male but more pronounced and distinct. 
Wings hyaline tinted at the extreme base with pale amber or saffron. Trigone 
of forem'ngs with 4 to 5 cells, 5 in the hind ; loop with 4 to 5 cells ; hypertrigones 
traversed 3 times in all wings ; 5 to 6 cells in the anal triangle ; nodal index : —

Membrane ashy, small. 
Legs yellow, the joints black as also are the spines on femora and tibiae. 
Anal appendages extremely short, filiform, pointed at the apex, brown. 
Dentigerous plate rounded and subdenticulate. 
Hob. Bengal. Darjiling District. I am indebted to Mr. H. Stevens for 
the chance of examining a number of these insects. The male as far as I know 
has not yet been described. The co-type male is in my own collection. I find 
as a result of my examination that the venation of this species varies very 
widely and to a less extent, the same applies to the markings. From this I 
deduce that the number of species described by Martin will probably resolve
