Ty[)e deposited in the Forest Research Institute, Dehra Dun. 
Abdomen with appendages 56 mm. Hindwing 53 mm. 
Head. Eyes dark olivaceous brown, probably greenish in the living state . 
labium and labrum bright ochreous, the latter bordered narrowly Avith dark 
brown ; face greenish yellow, upper surface of frons sky blue, the base narrowly 
black with a small, triangular projection m the middle line ; vesicle greenish ; 
occiput yellow, the surface wrinkled, posterior border slightly concave, simple. 
Thorax mriform grass green, beneath violaceous brown. 
Legs black, the femora dark reddish brown, hind femora with a row of small 
closely-set, evenly sized spines and 2 to 3 larger ones at the distal end. 
Abdomen very tumid at the base, cylindrical and tapering thereafter, 7, 8 and 
9 somewhat dilated. Segments 1 and 2 grass green except at the apical half of 
the dorsum of the 2nd which is blue, 3rd segment with a small patch of blue 
at the sides, basad, rest of abdomen dark blackish bro\vn, each segment marked 
w'ith 3 lateral, dark yellow spots, one basal, one apical and the third subbasal ; 
segment 7 has only 2 of these spots and 8 and 9 only one which is situated 
apical-ward. 
Anal appendages very short, spatulate, rounded at the tips, shaped very much 
like thbse of A. petalura. 
Dentigerous plate rounded, coated with minute, black spines, very similar to 
the plate of A. guttatus. 
Wings very broad and hyaline, the bases of the hind enfumed in the subcostal 
space and anal triangle ; stigma pale brown, very long and slender ; trigones of 
fore-^vings mth 6 cells, 4 in the hind ; nodal index

black, its extreme base white, very long ; 12 cells in the loop ; hypertrigones 
traversed 3 times in the forewing, 2 in the hind ; 5 cubital nervurcs in the 
forewing, 4 in the hind ; costa yellow. 
The species which belongs to the guttatus group is very similar to the female of 
.4. guttatus but is easily distinguished from all other .species by the distinctive 
character of its anal appendages.
