These females belong to this species I believe, though Wiede- 

 mann's description is wanting in particulars, but the face with the 

 deep black spots on each side and the similar spot between the 

 antennae, the ochre-brown frontal callus, the yellowish red an- 

 tennae, the whitish or greyish markings on base of thorax and on 

 scutellum besides the usual stripes, and the pale reddish femora 

 white haired, brown at apex, serve to distinguish the species with 

 the help of the figure of wing given by v. d. Wulp, to which the 

 above specimens correspond. The wing appears to the naked eye 

 distinctly marked with brown and white, the brown colouring 

 being so disposed as to appear a dark square blotch surrounding 

 the stigma with another similar one above, separated from it by a 

 pale interval ; the apical band is double, its lower larger half united 

 to a pale blotch in the first posterior cell in Wulp's figure, but in 

 these specimens it is usually disconnected. Length of specimens 

 9-I — 10 mm. 



2 . Face greyish w ith silvery white pubescence ; the large deep 

 black spots very distinct between the eyes and the antennae, the 

 centre of face just below antennae is also blackish. Palpi pale 

 yellow with short black pubescence and some longer white hairs at 

 base and on upper side. Antennae yellowish red, the first joint a 

 little incrassate after the base, but not broader than the basal 

 annulation of third joint, which it about equals in length ; it has 

 dense black pubescence, as has also the second joint which is ex- 

 tremely small, the third joint devoid of pubescence, the basal 

 annulation large, with the three apical annulations very small and 

 narrow. Forehead brownish grey, the two black paired spots large, 

 not touching the frontal callus which is shining yellowish brown, 

 barely reaching the eyes, its upper border straight but produced 

 in the middle, its lower border concave, receiving the black spot 

 between the antennae ; no unpaired spot present or only represented 

 by a small brown spot. Thorax brownish grey with short pale 

 fulvous pubescence on its dorsum, the three grey stripes distinct, 

 narrow, the lateral ones ending in a grey spot at median suture of
