1668 Insects. 



much more delicately pale, in its more slender legs and paler tarsi. 

 Of this beautiful species I captured two specimens of each sex at 

 Birch Wood, Kent, in 1842, since which, I have not met with it. I 

 expect it is extremely local and rare. 



Sp. 5. Andrena cingulata, St. Fargeau. 

 Nomada cingulata, Fab. male. Andrena labiata, Fab. female. 

 Melitta cingulata, Kirby. Apis albilabris, Panzer, male. 



Female. — (Length 4j lines). Black, shining, the pubescence cine- 

 reous, a line of short white hair along the inner margin of the eyes ; 

 the antennae rufo-piceous beneath. Thorax, the tegulae rufo-piceous ; 

 the wings subhyaline, their apex slightly fuscous ; the nervures nigro- 

 piceous; the floccus white, as well as the scopa beneath, above it is 

 fulvous. Abdomen ovate, finely punctured, the second and third seg- 

 ments red, the second has on each side a small black dot, the anal fim- 

 bria fulvous ; beneath, the second, third, and base of the fourth seg- 

 ments red. 



Male. — (Length 4 lines). Black, with a white pubescence ; the 

 clypeus white, with two black dots ; the antennae fulvous beneath. 

 Thorax, the tegulae piceous ; the wings as in the female. Abdomen 

 oblong-ovate, very convex, the second, third, and base of the fourth 

 segments laterally red, the second has a minute black dot on each 

 side. 



This species does not appear to be subject to much variation. I 

 have frequently captured it in the neighbourhood of London, in May 

 and June ; but it is rather a local species.

 litta Schrankella, Kirby.

 the wings subhyaline, their apex slightly clouded ; the legs have a 

 cinereous pubescence, which is also the colour of the floccus, and of 

 the scopa beneath, the latter is of a brownish-black above. Abdomen
