margin of the eyes. Thorax, a little pale fulvous pubescence on 

 the disk ; the wings splendidly iridescent, sub-fuscous, with their 

 tegulae piceous ; the legs have a pale fulvous pubescence, which is 

 also the colour of the scopa above, but it is silvery beneath, changing 

 colour in different lights ; the floccus white. Abdomen ovate, nearly 

 naked ; the apical fimbria pale fulvous. 



Male. — (Length 3 lines). Black ; the face clothed with black pu- 

 bescence ; the tegulae piceous ; the wings splendidly iridescent, sub- 

 fuscous; the legs have a hoary pubescence ; the claws ferruginous. 

 Abdomen sub-ovate, nearly naked, the extreme apex piceous. 



Mr. Kirby has remarked that A. minutula, nana and parvula, are li- 

 able to be confounded, although distinct species : the female of minu- 

 tula has the underside of the antennae more or less red towards the 

 apex, its wings are brown, and its abdomen is impunctate : A. nana 

 has the abdomen punctulate, and lateral marginal fascia : A. parvula 

 has an ovate abdomen, and its antennae are wholly black. The male 

 of A. parvula is at once known by its black face : the male of nana 

 has a longer abdomen and also longer antennae than the male of mi- 

 nutula, and its wings are paler.

 the wings slightly fuscous ; the legs nigro-piceous, their pubescence 

 nearly white ; the floccus white ; the scopa fuscous above, silvery- 

 white beneath ; the posterior tarsi fulvous within ; the apical joints 

 of all the tarsi piceous. Abdomen oblong-ovate, shining, punctate ;

This is a scarce little bee. I have taken it in the autumn at Graves- 

 end : I have also seen specimens captured at Southend in August. I 

 do not know the male.
