$ . Elongate, greenish-grey, clothed with pale hairs ; head slightly longer tlian 

 the prothorax, greenish ; antennte brownish -grey, 2nd joint not quite so long as the 

 3rd and 4tli together, slightly iiicrassated, 3rd about three-fourths as long as the 

 2nd, 4th not quite half so long as the 3rd ; prothorax nearly twice as wide at the 

 base as long, anterior margin about two-thirds the length of the base, sides nearly 

 straight, their margins acute ; colour greenish-grey on the disc, inclining to green

 surface of whole insect rather more densely pubescent than in the (J , and of a

The ^ is easily known by its narrow form ; the ? is very like 

 that sex of qfflnis, but may be distinguished by its rather smaller size 

 and the absence of the black bristly hairs observable in that species. 

 E-euter only records this species from Corsica, South France, and 

 Landes (Ferris). It is interesting that the two species of Amhlytylus 

 recently introduced from Woking, viz., delicatus, Ferr., and hrevicollis, 

 Fieb., should both be South European in their hitherto known 

 distribution.

NOTE ON ANDRENA TRIMMERANA, KIRBY, AND A. ROS^, PANZ. 

 BY R. C. L. PERKINS. 



In his recently published Catalogue of our Aculeate Hymenoptera 

 Mr. Edward Saunders queries Andrena rosie, Fz., as a variety of A. 

 Trimmerana^ Kirby. I have for some time been convinced that the 

 former has no right to rank as a species, being merely (as suggested 

 in the " Synopsis ") the second brood of A. Trimmerana. The struc- 

 tural characters whereby the two have been distinguished are (1) the 

 entire ventral valve of the 8th segment in $ rosoe, whereas in ,^ Trim- 

 mermia it is deeply emarginate ; and (2) the simple impunctate (at
