(5 2 . Head : frons and back of head lighter or darker grej. 

 Proboscis robust at base, pointed, moderately long, pubescent, 

 brownish yellow : palpi dark brown. Antennae: 1st joint large, 

 globular, yellowish brown ; flagellum apparently of twelve joints, 

 brownish yellow, closely pubescent, filamentous towards the tip, 

 making it difficult to discover the exact number of joints. Thorax : 

 dorsum grey, sometimes a little jellowish, sometimes almost 

 whitisb. Three dark brown stripes, the median one, which is 

 very narrowly divided more or less b}^ a longitudinal pale stripe, 

 runs from tbe anterior margin to beyond the middle, posterior to 

 which it continues, much narrowed. The two outer stripes which 

 are separated from the median one by a narrow space, begin some 

 distance behind the shoulder and continue to the posterior margin 

 of the dorsum ; the space between them, posterior to the broad 

 part of the median dark stripe, being light grey, traversed longi- 

 tudinally by the attenuated continuation of the median stripe. 

 A more or less indistinct transverse streak, or darker space, on 

 the shoulders, brown or grey, of a lighter or darker shade, some- 

 times with traces of a thin line connecting them. Scutellum 

 yellow ; metanotum brownish. Sides of thorax brownish or 

 brownish grey, iri'egularly tinted. Abdomen dark brown, with 

 very sparse pale hairs. Genitalia of male very small, yellowish, 

 mainly concealed ; the tips of (presumably) a pair of small 

 claspers are visible. Ovipositor of female small, with a reddish- 

 brown tip. Legs pale brownish yellow ; tips of femora and tibiae, 

 and the tarsi towards the tips, blackish ; the hind tibiae being very 

 distinctly though not greatly incrassated. Wings pale grey, with 

 three moderately small pale brown spots. The first embraces the 

 end of the prsefurca, the base of the fork of the 2nd vein, and the 

 anterior cross-vein ; the second spot is in the middle of the basal 

 cell ; the third is placed across the middle of the 5th vein, thus 

 falling across both the 2nd basal and the anal cells. A very pale 

 grey, irregular, narrow, but distinctly perceptible streak joins 

 the fork of the 2nd vein to the fork of the 4th. In addition there 

 are some indistinct pale grey spots placed apparently irregularly 

 in the basal half of the wing. Halteres yellowish. 



Length 2-3 millim. 



Described from three males and two females in the Indian 

 Museum collection, all captured by Dr. Annandale in the Simla 

 district, with the following data :— Simla, 7000 ft., 10. v. 09 [type 

 male); Barogh, 5000 ft., 10. v. 10 ; Phagu, 9000 ft., 11. v. 09 

 {type female). 



This species must bear some resemblance to the common 

 European B. maculata, Mg. Of the descriptions available to me 

 that of this species is the only one in which the slight but very 

 distinct incrassation of the hind tibiae is mentioned. Tet this
