316. Rhypholophus geniculatus, sp. nov. 



3 . Head : vertex and frons very broad, covered with short 

 golden yellow hairs ; eyes deeply emarginate ; palpi dark brown, 

 cousiderably pubescent. Antennal scape pale yellow; flagellar 

 joints elongate oval, rather thickly pubescent, with pale brownish 

 yellow hairs, brown, tips pale yellowish white, the joints becoming 

 longer and narrower towards the tips of the antennae. Thorax 

 yellowish, indistinctly darker along the micldle, and where the 

 usual shorter dorsal stripes occur ; darker also behind the suture ; 

 a small shining elongate black spot in a small depression on each 

 side of the middle, a little before half-way between the anterior 

 margin and the suture. Thorax pubescent, with short yellow 

 hairs, and a dorse-central stripe of irregularly placed longer 

 thicker yellow hairs along each side of the middle, well separated. 

 Scutellum with yellowish hairs. Abdomen black, with compara- 

 tively thick yellow pubescence. Genitalia large, black, the 

 1st joint of the claspers oval, the remaining appendages 

 apparently small. Legs : anterior legs dark brown or black, 

 with short pubescence, which in certain lights appears golden 

 yellow ; a moderately broad band of very short golden yellow 

 hair at tips of femora, extending in some cases to the base 

 of the tibiae ; tips of tibiae with a very narrow similar band ; 

 the hind tibiae changing rapidly before the middle to yellowish, 

 with short distinct yellow pubescence, and the whole of the hind 

 tarsi yellowish, with concolorous pubescence. Wings very pale 

 yellowish grey, rather thickly covered with short black hairs, 

 with whicli are intermixed, in places, short golden yellow ones, 

 there being no distinct stigma, but the yellow hairs are especially 

 prominent in that part of the wing. The black hairs are arranged 

 so that they form four more or less distinct, though not well- 

 defined, bands of about equal width, with a rather narrow interval 

 between each ; the first band basal, the fourth apical, the second 

 ending distinctly before the cross-veins, at which latter spot the 

 third begins ; the yellow hairs more numerous between the bands 

 of black hairs, llalteres yellow.
