"Body robust; wings of the males generally with a splendid piirplish gloss, the anterior emar- 
ginate in the middle of the apical margin. 
" Head of moderate size, larger in tho males than in the females, hairy, slightly tufted in front. 
" Eyes prominent, naked. 
"Anteninv about equal to three fifths of tho length of tho fore wing, nearly straight; 
terminated by a rather strong elongate-ovate club, compressed and delicately keeled along 
the inside. 
"■ Ma.viU(v long and spiral. 
" Labial iialpi porrected obliquely, the tip rising nearly to the level of the top of the eyes. 
Inner surfaces parallel, nearly united together, so as to form a conical beak nearly as long 
as the head, thickly clothed with short scales ; the base beneath, the inner surface of the 
middle joint, and the terminal half of the iipper surface furnished with elongated hairs 
the basal joint very short ; second joint very long, slender, and curved ; the third not 
longer than the basal joint, elongate-conic, pointed at the tip. 
" Thoeax robust, subovate, very woolly in front and behind. 
" Fore xi'inrjs elongate-trigonate ; anterior margin moderately arched ; apical angle subtruncate ; 
apical margin more than two thirds of the length of the anterior, slightly scalloped, and 
more or less emarginate in the middle ; inner margin nearly straight, a little longer than 
the apical one. Veins very strong ; the costal one extending to tho length of two thirds 
of the costa from the base : postcostal vein with the first branch arising a little before the 
anterior extremity of the discoidal cell ; second branch arising at one third of the 
length of the wing, just before or exactly at the extremity of the cell ; third branch 
arising just beyond the middle of the wing, and extending to the apical angle ; fourth branch 
arising at four fifths of the length of the wing. Upper discocellular vein obsolete ; middle 
discocellular arising at the anterior extremity of the discoidal cell, at the distance of one- 
tbird of the length of the wing from the base, very short, and forming the curved branch 
of the lower discoidal vein ; lower discocellular vein obsolete, so that the discoidal cell is 
open. 
" Hind wiwjs triangular-ovate; the apical angle more or less elongated; outer margin scalloped. 
Inner margin deeply grooved to receive the abdomen, with a deep sinus between the body 
and the anal angle. Precostal vein strongly curved, its extremity directed outwards from 
the body. Postcostal vein branched at a short distance from its base. Discoidal cell not 
closed, the outer discocellular vein being obsolete. 
" Fore legs of the male very short and slender, clothed with delicate white hairs. Tibia shorter 
than the femur. Tarsus about two thirds of the length of the tibia, very slender, and, 
•when denuded of its hairs, four-jointed ; the joints not indicated by short spines, and the 
apical joint very minute, simple, and destitute of apical claws. Fore legs of the female 
very slender and scaly. Femur within clothed with short white flossy hairs. Tarsus two 
thirds of the length of tho tibia, nearly cylindrical, siiboblique at the tip, and articulated, 
with short spines beneath indicating the joints.
