12 PIPUSCULID^. 



length of the antenna, the absence of any shuiing bhxck segment 

 in the abdomen, and the almost bare thorax are tlie only differences. 



The frons is about one-tenth the width of the head (measured 

 immediately above the antennae), as is shown in Verrall's figure*, and 

 as is the case in the European specimens before me. Mr. Verrall, 

 however, says in the text that the frons is only one-twentietli the 

 width of the head. 



This species iu typically marked specimens is easily distinguished 

 from biroi by the black apical half of the tibiae, and from my 

 cinereo-ceneAis by its black antennae and halteres, and the mainly 

 black legs. However, three specin)ens in the Indian Museum 

 appear to show an intermediate form which may possibly be a 

 third species. The antennae are white-tipped, the body colour 

 dark grey, the abdomen quite similar to that of biroi, but the 

 tibiae show the black apical half in two specimens and distinct 

 traces of them in tlie third, which would associate the form with 

 the variety Jiimalayensis. The greyish thorax and abdomen and 

 distinctly whitish-tipped antennae seem to prevent them being any 

 form of campestris. Moreover, in one of the two males (the third, 

 the Sahelwa specimen, is a $ ) the tip of the antennae is produced 

 into a long bristle as in my filicornis- Thev show the following 

 data: Simla, 9. v. 1909; Theog, Simla Hi'lls, 13. v. 1909 (both 

 Annandale) ; Sahelwa, Bahraich District, United Provinces,
