Mr. F. Smith on the Synonymy of the genus Nomada. 441 



as I can assert, having frequently examined the original specimens 

 in the Kirbyan cabinet. With us it appears in the autumn, as do also 

 solidaginis and Roberjeoliana. 



Sp. 28. interrupta, Panzer. 



I am unacquainted with this species. 



Sp. 29. nobilis, Schaffer. 



Nomada nobilis, Schaffer, Germ. Zeits. vol. i. pt. 2. 278. 29. 



I have seen specimens of this species from Albania ; it has not 

 hitherto occurred in England. 



Sp. 30. succincta, Panzer. 



Nomada succincta, Panzer, Faun. Ins. Germ. 55. tab. 21. 



Very nearly allied to the Apis Goodeniana, Kirby, but I think 

 distinct, as the male of Kirby's insect has neither yellow legs nor a 

 black spot on the posterior tibia, both strong specific characters. 



Sp. 31. cincta, Schaffer. 



Nomada cincta, Schaffer, Germ. Zeits. vol. i. pt. 2. 288. 32. 

 This is a species that is unknown to me. 



Sp. 32. alternata, Kirby. 



Apis alternata, Mon. Ap. Angl. vol. ii. 182. 5. 



This is a variety of the male of Marshamella, in which the usual 

 yellow spots on the scutellum are obsolete. 



Of the species which were unknown to Herrich- Schaffer, it may 

 be probably useful to offer a few observations, although the syno- 

 nymy will point out their true position. 



First, the Apis caprce of Kirby is only a small variety of A. cor- 

 nuta — the rufous fascia on the first abdominal segment reduced to 

 two minute rufous spots, the two yellow spots on the scutellum 

 obsolete, and the horn on the lip nearly so ; the abdomen beneath 

 rufo-piceous, and not marked with yellow. The Apis lineola of 

 Panzer and Kirby is also a variety of A. cornuta ; or rather I should 

 say, A. cornuta is the variety, Panzer's name being the oldest. 



Apis Lathburina : the A. rufiventris is the female of this species. 

 It is parasitic upon Andrena labialis. 



Apis picta and rufo-picta are both varieties of the N. solidaginis of 

 Panzer, which varies so greatly in colouring, as I have already ob- 

 served. 



Apis sexcincta, Kirby, is the male of N. lineola ; it is very much 

 like the male of N. Marshamella, but is quite a distinct species ; the 

 most obvious differences are, that it has bright yellow tegulse, the 

 legs mottled more or less with yellow, and the abdomen more con- 

 vex ; it is also usually a larger insect, and is of much rarer occurrence.
