Mi\ J. \\'alton on the (jenus Apiou. 335 



1 liavc found this insect very abundant near Low Harrowgatc, 

 Scarborough, and at other ])laces in Yorkshire, invariably on Vicia 

 Cracca in the month of Aujz:u.st ; and also at Lyndluu'st. Taken 

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

IMr. Kirby suspected that Ajt. marchicum was but a sexual va- 

 riety of Ap. vircns ; the male has the rostrum distinctly shorter 

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

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



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

 south of Eng-land on hedge-banks and amongst grass in the 

 spring and autumn.

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

 beautiful insect ; they were taken by him near Northampton iu 

 June ; it inhabits Astragalus ghjcyphyllus, 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 api)ears 

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

 sought for it year after year^ Astragalus ghjcyphyllus 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 Ap. angustatum; and specimens previously forwarded 

 to Schonherr by jNJr. Waterhouse were returned ^^^th the same 

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

 them is as follows : " Ap. Loti of Kirby [S) 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 cited 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 Yorkshii-e, at
