NEW SPECIES OF INDIAN HYMENOPTERA. 565 



forms somewhat broad bands on the apical margins of segments ; wings 

 clear hyaline, tegulae shining testaceous, nervures testaccoi s, stigma paler. 



$ Similar, smaller, apices of abdominal segments depressed ; the 

 whole of the pubescence grey, but not so dense ; clypeus and a large 

 spot on each side of it, reaching the inner orbits of the eyes, pale yel- 

 lowish ; antennae below paler red, tarsi pale testaceous ; the apices 

 of the abdominal segments narrowly testaceous, but this is frequently 

 not apparent owing to the pubescence. 



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



Habitat — Peshin ; common in April. 



I cannot find that the 9 is very near to any other species. The 



$ is allied to A. satelliia, described below, but may be distinguished 



from it by the flagellum being pale red below, not piceous. It may 



be distinguished from the same sex of A. flavo-faeies by the mandibles 



being wholly black. 



Andbena flagella, n. sp. 



9 Clypeus minutely aciculate, with a few very shallow punctures ; 

 head and thorax minutely punctured, the enclosed space at base of 

 median segment narrow, with fine lateral striae at base ; abdomen minute- 

 ly and closely punctured ; lamina at base of labrum broadly rounded 

 at apex, a small tubercle near the base of mandibles ; antennae with 

 the scape very long and narrow, 2nd joint of flagellum as long as the 

 three following, very narrow at base, gradually widening towards apex ; 

 a carina from between bases of antennae to anterior ocellus ; sides of 

 front along inner orbits of eyes depressed, with fine depressed pubes- 

 cence, this being particularly noticeable from above, vertex sharply 

 narrowed above, and very convex ; abdomen scarcely as long as head 

 and thorax united, its apical segment incised. Black ; the flagellum 

 rufo-piceous, calcaria testaceous, claws rufescent ; pubescence greyish- 

 white, clypeus in type specimen without pubescence, probably owing to 

 abrasion, mesonotum with sparse pubescence ; on the sides of the median 

 segment it is long, silky and snow-white ; on the apical margins of 

 abdominal segments 1 — 4 it forms somewhat broad, uninterrupted, 

 snow-white bands ; anal fimbria brownish on 5th, black on Gth 

 segment ; pubescence on legs and scopa short and greyish-white, 

 except on the tarsi, where it has a pale golden tinge, especially en the 

 inside ; wings hyaline, nervures and tegnlae testaceous.
