Stylonotus obscurus, Westw. 



McLaclilan refers to this (Trans. Ent. Sac. London for 

 1891, p. 513) as a lost species. It is represented in the collection 

 before me by one male and four female specimens. Evidently 

 Westwood knew only the female, for he could not have missed 

 describing the extraordinary process that arises from the back of 

 the male abdomen. The females agree well with his description, 

 not all of them, however, showing clearly the velvety black lines 

 on sides of the basal abdominal segments; but some of them 

 show these lines finely. The male may be described as follows : — 



Length 26 mm. Antennae 16 mm. Expanse of wings 55 mm. 

 Length of fore wing 23 mm., of hind wing 19 mm. Brownish.

more or less hairy about the face, the sides of the thorax and the 

 base and apex of the abdomen a vertical line of shining yellowish 

 brown on the cheeks next the e3'es; vertex tipped with long 

 erect yellowish hairs. Rear of head smooth, shining, black on its 

 lower half, yellow on the upper, with a transverse black line 

 each side traversing the yellow area. Legs yellowish. Wings 

 hyaline with clear reddish-brown veins and a reddish stigma that 

 covers about four cells. Abdomen brown, paler at base, where 

 encircled with long whitish hairs ; the third segment bears a long 

 apical stylus twice as long as the segment, clothed beneath its 

 obtuse tip with short dense black pubescence. Terminal abdom- 

 inal appendages short and concealed by the apical hairs. The 

 single male specimen is from Kulu, W. Himalayas (Reg. No. "V*). 

 There are two females from the same locality and two 

 from Mundi, Kangra district, W. Himalayas (3,200 ft.) (Reg. 

 Nos. -'•-V-, "¥-).
