Mr. J. Walton on the genus Apion. 335 



I have found this insect very abundant near Low Harrowgate, 

 Scarborough, and at other places in Yorkshire, invariably on Vicia 

 Cracca in the month of August ; and also at Lyndhurst. Taken 

 by Mr. S. Stevens near Edgeware, and at Hampstead in July.

Mr. Kirby suspected that Ap. marchicum was but a sexual va- 

 riety oi Ap. virens; the male has the rostrum distinctly shorter 

 and stouter, with the antennse inserted at the middle ; I have no 

 doubt whatever that the former is the male of the latter. 



It is rather a common species, and found in the north and 

 south of England on hedge-banks and amongst grass in the 

 spring and autumn. 



44. A. Astragali, Payk., Kirb., Gyll., Germ., Steph., Schonh. 



I am indebted to R. N. Greville, Esq., for specimens of this 

 beautiful insect ; they were taken by him near Northampton in 

 June ; it inhabits Astragalus glycyphyllus, and is found in June 

 and July. I have frequently examined that plant in the north 

 and south of England, but I never met with the insect ; it appears 

 to be extremely local and periodical in its appearance : Mr. Kirby 

 sought for it year after year. Astragalus glycyphyllus being abun- 

 dant near his residence, but never found it more than once.

Ap. angustatum was described by Kirby from a Swedish in- 

 sect which is certainly a narrow female variety of Ap. Loti ; ex- 

 amples of the latter, which I sent to Schonherr, were named by 

 that author ^jo. angustatum; and specimens previously forwarded 

 to Schonherr by Mr. Waterhouse were returned with the same 

 name. I likewise sent specimens to Germar ; his note relative to 

 them is as follows : '^ Ap. Loti of Kirby (c^) and Ap. angusta- 

 tum ( ? ) are no doubt the same species ; until the present time 

 I possessed only one injured specimen, presented to me by Mr. 

 Spence ; my Ap. modestum is identical with Ap. angustatum.^^ It 

 is upon Mr. Kirby^s authority that I have citGd Ap. glabratum as 

 a synonym, from the following note in his manuscript book : '' gla- 

 bratum of Spence, var. Apion Loti, K.^^ This I communicated to 

 Germar in a note under Ap. Loti, but he made no observation 

 upon it. 



I have found this species rather abundant in Yorkshire, at
