440 Mr. F. Smith on the Synonymy of the genus Nomada. 



Syst. Piez. 392. 7 (male); Schaffer, Germ. Zeits. vol. i. pt. 2. 



284. 23 (male and fern.) ; St. Farg. Hist. Nat. Ins. vol. ii. 472. 8 



(male and fern.) ; Smith, Zool. vol. ii. 595. 8 (male and fern.) ; 



Nylander, Mon. Ap. Boreali, p. 176. 3 (male and fern.). 

 Apis solidaginis, Kirby, Mon. Ap. Angl. vol. ii. 204. 22 (male and 



fern.). 

 Apis picta, Kirby, Mon. Ap. Angl. vol. ii. 204. 22 (fern.). 

 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. 



Sp. 24. sexfasciata, Jurine. 



Nomada sexfasciata, Jurine, Panzer, Faun. Germ. 68. 18 (male) ; Illi- 



ger, no. 37 ; Schaffer, Germ. Zeits. vol. i. pt. 2. 285. 24 ; St. Farg. 



Hist. Nat. Ins. vol. ii. p. 471. 7 ; Smith, Zool. vol. ii. 258. 18. 

 Apis connexa, Kirby, Mon. Ap. Angl. vol. ii. 199. 19 (male) ; Schaff. 



Icon. 81. 7. 

 Apis Schcefferella, Kirby, Mon. Ap. Angl. vol. ii. 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, Schaffer, 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 altemata, 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. altemata 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. Jacobace, Panzer. 



Nomada Jacobaa, Panz. Faun. Germ. 70. fig. 20 (male) ; Schaffer, 



Germ. Zeits. vol. i. pt. 2. 286. 27 ; St. Farg. Hist. Nat. Ins. vol. ii. 



479. 15; Smith, Zool. vol. ii. 594. 7 ; Nylander, Mon. Ap. Boreali, 



176. 3. 

 Apis Jacobcete, 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 Jacobaa,
