<$ J . Head : frons in 6 six times, in $ tliree times as wide at 

 level of antennae (where it forms nearly one-third the width of the 

 head) as at vertex, black, and, as is also the face, covered thickly with 

 dense erect stiff black pubescence, amidst which numerous small 

 bright yellow depressed scales are visible, more numerous on the 

 face, where they are intermixed with yellow hairs; antennae black, 

 3rd joint moderately elongate, with rather long style ; mouth- 

 parts reddish brown or blackish ; hind margin of eyes with a narrow 

 fringe of small white impressed scales, which perhaps may extend 

 over most of the occiput. Thorax black, dorsum covered with 

 minute bright yellow impressed scales, either placed on top of 

 (forming an upper layer) or intermixed with similar dull black 

 scales;* fine long black hairs are scattered irregularly over the 

 dorsum ; margins of dorsum with thick bright yellow scaly 

 pubescence, a few black bristles at sides in front of wings and 

 three or four brownish-yellow spines on posterior corners, directed 

 backwards. Scutellum like thoracic dorsum ; hind margin with a 

 row of long yellow hairs and (apparently) some yellow bristles 

 and some elongate black scales. Abdomen : integument between 

 thorax and abdomen whitish grey ; dorsum of abdomen black, 

 mainly (or entirely ?) covered with very small impressed black 

 scales, and apparently the greater part covered in good specimens 

 with small yellow scales ; margins of dorsum and sides of abdomen 

 with dense long fine scaly pubescence, the dorsum covered more 

 thinly, though, when viewed at a low angle from behind that part, 

 it appears almost as thickly covered as the sides ; this pubescence is 

 rather darker yellow in the 2 ; on hinder part of dorsum in $ 

 the pubescence is black. Hind margin of 6th segment narrowly, 

 and basal three-fourths of 7th, with yellow scales ; remainder of 

 7th with black scales ; sides of 5th and 6th segments with thick 

 bristly black pubescence ; ground-colour of side margins of first 

 three segments in c? yellowish ; venter black, with minute black 

 and yellow impressed scales and some fine yellow pubescence. 

 Legs black ; femora with closely-placed small black scales, which 

 in certain lights have a greyish tinge ; small yellow scales also 

 present; tibiae and tarsi with small black scales and bristles. 

 Wings practically clear; costal and subcostal cells dark brown, 

 the colour extending irregularly over praefurca and also at extreme 

 base proximadto basal cells; anterior cross-vein just before middle 

 i( J ) or at first 3rd ( 2 ) of the discal cell ; halteres pale yellow. 



Length, lOg-llmm. 



Redescribed from a S from Majkhali, Western Himalayas, 



* The dorsum of the c? specimen is mainly denuded, that of the 2 partly 

 so, but probably a double covering of scales is present in perfect specimens.
