Apis picta, Kirby, Mon. Ap. Angl. vol. ii. 204. 22 (fem.). 
Apis rufo-picta, Kirby, ditto 207.) ditto: 
The colouring of the male of this species is very constant, whilst 
that of the female varies greatly ; on the abdomen the colour ranging 
from black to pale red. These varieties embrace the picta and rufo- 
picta of Kirby.

Apis Schefferella, Kirby, Mon. Ap. Angl. vol. i. 199. 18 (fem.). 
This is the largest species of the genus found in England ; it is 
very local, being parasitic upon Eucera longicornis, from the cells of 
which I have extracted both sexes. 
Sp. 25. Marshamella, Kirby. 
Nomada Marshamella, Schiffer, Germ. Zeits. vol. ii. pt. 1. 285. 25 ; 
Smith, Zool. vol. ii, 590. 3; Nylander, Mon. Ap. Boreali, 177.5. 
Apis Marshamella, Kirby, Mon. Ap. Angl. vol. ii. 188. 10. 
Apis alternata, Kirby, Mon. Ap. Angl. vol. ii. 182. 5 (var. male). 
Schaffer supposes the A. cornigera and subcornuta to be varieties 
of this species, but in this he is quite mistaken ; subcornuta is a va- 
riety of cornuta, but the latter is a good and distinct species, having 
a different male to Marshamella, and much more rare or local, and 
not appearing so early in the season. ‘The A. alternata of Kirby is 
merely a variety of the male in which the spots on the scutellum are 
obsolete. 
Sp. 26. affinis, Schaffer. 
Nomada affinis, Schaffer, Germ. Zeits. vol. i. pt. 2. 286. 16. 
I think this is undoubtedly a variety of the foregoing ; the slight 
differences pointed out come within the range of variation to which 
this species is subject. 
Sp. 27. Jacobee, Panzer. 
Nomada Jacobee, Panz. Faun. Germ. 70. fig. 20 (male) ; Schéffer,

Apis Jacobee, Kirby, Mon. Ap. Angl. vol. ii. 201. 20 (male). 
Apis flavo-picta, Kirby, Mon. Ap. Angl. vol. ii. 202. 21 (fem.). 
The Apis flavo-picta of Kirby is undoubtedly the female of Jacobea,
