Mr. J. Walton on the genus Apion. 



Kirby and Stephens appear to have described the female, and 

 to have ascribed the remarkable subflexuose appearance in the 

 form of the anterior tibise to that sex, but it is a character pecu- 

 liar to the male. It is a very active insect and runs with great 

 rapidity. Small varieties of the female occur which have a great 

 resemblance to the same sex of Ap. pavidum. 



Plentiful near Knaresborough in Yorkshire, in woods and 

 hedges upon various plants, in June and July ; it also occurs not 

 uncommonly in the south, I believe generally in woods.

Frequently taken in many localities in the north and south of 

 England, and found abundantly in the chalky districts of Kent 

 and Surrey upon Trifolium procumbens and Hedysarum Onohrychis 

 in June.

The sculpture of this very distinct species is subject to varia- 

 tion. Kirby and Stephens describe the head rugulose between 

 the eyes ; the thorax deeply punctured, with a very obsolete dorsal 

 channel', the elytra subsulcate: Gyllenhal describes the frons as 

 obsoletely striated; the thorax closely but obsoletely punctured, 

 with a small obsolete fovea before the scutellum ; the elytra deeply 

 punctate- striate. 



Kirby has cited the following as varieties : — 



Var. 13. the elytra sulcate with the interstices convex. 



Var. y. the thorax without a fossulet or a line. 



Var. 8. the head with three sulci between the eyes. 



" Var. /3. may be distinct, but it differs in nothing but the 

 convexity of the interstices of the elytra. 



" I took 8. upon the bean ; it may be distinct, but it differs in 

 scarcely any point except the furrows between the eyes.'^ 



In my series of seventy specimens, the principal part have 

 between the eyes three or four very distinct sulci; some of 

 them are faintly or less deeply carved than in others, but with a 

 lens of a quarter of an inch focus, all have them more or less di- 

 stinct ; the thorax rather closely and deeply punctured, the punc- 

 tures varying in magnitude and depth, but always very distinct, 

 with a striolet or a large puncture before the scutellum, some- 

 times obsolete or wanting ; the elytra elegantly engraved, very 

 deeply and distinctly punctate-sulcate, the sulci catenulate-punc-
