Abdomen. — The ist segment brownish-yellow, hinder part at 

 sides dark chocolate-brown, with a large irregular oval white spot 

 on each side, nearly or quite reaching the upper side ; 2nd segment 

 very narrow, barely wider at tip, pale yellowish, an irregular, lighter 

 brown dorsal stripe, and at each side towards tip, a short dark brown 

 stripe ; tip of 2nd segment more or less white both on dorsum and 

 at sides; 3rd and 4th segments dark chocolate-brown, with two 

 slightly curved, narrow elongate spots (convex side inwards), from 

 towards the sides at the base of the segment, and extending to 

 the hind margin, where they are still widely separated. These 

 spots are yellowish on the 3rd and chalk-white on the 4th and 

 remaining segments but the colour may be a little variable. A 

 couple of small whitish spots towards each hind corner of the seg- 

 ments The 3rd and 4th segments are both very considerably 

 wider at tip than base, the 5th and 6th are replicas of the 3rd and 

 4th, but the brown colour is lighter. The 7th segment is light 

 brown with two nearlj^ parallel white stripes. 



Belly brownish-yellow at base, lighter chocolate-brown from 

 3rd segment (inclusive) to tip, with two well separated white 

 stripes extending over the segments, the surface on the outer side 

 of these stripes black. There is a distinct 8th sternite, lighter 

 brown, well curved. The whole abdomen is practically bare. 



Genitalia comparatively very small, mainly concealed, brown, 

 an upper bifid oblong dorsal plate, and a pair of claspers with one 

 or two appendages. 



Legs. — Coxae white dusted, with a blackish spot on front side ; 

 remainder of legs brownish-yellow ; femora at tip, tibiae at base 

 and tip, and metatarsi at base, all with broad dark brown rings, 

 but not well delimited. 



Wingi: clear, ver^- shining, absolutely bare, the whole surface 

 transversely ribbed. The wing roots blackish, the stem of the 

 wing considerably elongated, a distance of 9 mm. before the wing 

 definitely widens. The ist posterior cell extremely narrow 

 throughout Its length, the petiole of the 2nd posterior cell almost 

 as long as the cell, and about as long as the discal cell ; the 6th vein 

 remarkably close to the 5th and taking a sudden bend at its 

 middle. 



Costal cell pale yellowish except for the clear tip ; the stigma- 

 tic portion and the region around the discal cell dark brown, 

 the colour extending uninterruptedly to hind margin of wing, 

 embracing tip of 5th vein. This brown colour encroaches narrowly 

 but distinctly on the apices of both basal cells, on the basal half 

 of the submarginal cell, extending very narrowly along its upper 

 (costal) side. The colour also fills wholly the ist posterior cell 

 (though here it becomes ^^ellowish) , and it borders narrowly the 

 upper side of the 2nd posterior cell, and the basal parts more 

 broadly of the 3rd, 4th and 5th. There is, in the brown colour 

 filling the discal cell, a triangular clear space of moderate size and 

 a small pale streak at tip of ist basal cell and also just above the 

 praefurca. The 5th longitudinal vein is rather broadly brown,
