forming apical bands on segments 2 — 4, with a trace of a band on apical 

 margin of 1st segment ; scopa and anal fimbria grey ; wings hyaline, 

 nervures and tegnlse testaceous. 



$ Only distinguishable from the same sex of A. bi-emarghiata, de- 

 scribed below, by the mandibles being yellow at base, and red in the 

 middle, instead of wholly black. 



Long. 9 7-8 mm. $ 6-7 mm. 



Habitat — Qnetta ; Peshin ; four specimens. 



This species is, I believe, the only one hitherto described in which 

 the 9 has the clypeus and front yellow. 



(c) Abdomen entirely black. 

 Andkena marmoka, n. sp. 

 9 Head and thorax very closely and finely punctured under the 



pubescence, which usually hides the sculpturing, triangular space at base 

 of median segment finely rugose, abdomen minutely, closely, and 

 shallowly punctured, except the apices of the segments, which are 

 depressed and impunctate ; eyes reaching the base of the mandibles, the 

 latter dentate at apex, the tooth small. Black ; the calcaria and claws 

 rufo-testaceous ; pubescence as follows : on head and thorax above 

 greyish white, snow-white on front and sides of median segment, 

 a black band across the thorax between the tegulae ; abdomen smooth 

 and shining, without pubescence above, but with lateral spots of snow- 

 white pubescence on segments 1 — 4, the spot on 1st segment small ; 

 5th segment with long, silky white pubescence, below which the anal 

 fimbria is black ; head, thorax and abdomen below with black pubes- 

 cence, except some greyish white hairs below the eyes, and sparse greyish 

 apical bands on the apical one or two segments ; legs with entirely black 

 pubescence, except the femora of the anterior and intermediate legs, 

 where it is long, silky and white ; forewing with the basal half hyaline, 

 apical half fuscescent, with some lightor patches ; hindwing hyaline, 

 its extreme apex infuscated ; nervures and tegula) blackish. 



Long. 12-13 mm. 



Habitat — Quetta ; Peshin ; not uncommon, but I did not secure a male. 



This species seems to be nearest to A. fuseo-calcarata (Mor.) from the 

 Caucasus, of which only the $ is known. It differs, however, in several 

 respects from the description of that species, of which I scarcely think it 

 is the other sex.
