396 Mr. J, Walton on the genus Apion. 



faintly impressed line terminating just before the fovea, with the 

 latter very distinct ; these agree typically with Ap. eheninum of 

 Gyllenhal ; the elytra are black and shining, the furrows very 

 deep, the interstices narrow and convex, finely coriaceous or 

 nearly smooth, with a tendency in some individuals to become 

 rather broader and less convex. 



I have no doubt this insect inhabits Lotus major ^ having many 

 times taken it plentifully from that plant in June and July, in 

 several places in the north and south of England.

— Grieshachii, Steph. 



Gyllenhal furnished PaykuU and Kirby with specimens of this 

 very distinct insect ; the characters which distinguish the sexes 

 are analogous to those of Ap. Ervi. Ap. Griesbachii, described 

 by Stephens in his ' Illustrations,' appears to have been sunk in 

 his ' Manual,' on my authority, but with a note of interrogation ; 

 specimens were submitted by Mr. Waterhouse to the inspection 

 of Schonherr, who remarked that they were scarcely sufficiently 

 distinct from Ap. Vicice ; I think there cannot be any doubt of its 

 being a variety of that species. 



I found this elegant insect very common in Yorkshire on the 

 Vicia Cracca ; but it appears to be rather local in the south ; I 

 once found it extremely abundant on the 19th of June at Birch 

 Wood, on the same plant, but never upon any other. 



62. A. Ononis, Kirb., Steph. 



— mecopsy Schonh. 



This species has a considerable affinity in form and sculpture 

 to Ap. pavidum, but it differs in being more thickly clothed with 

 hair, and in having the head distinctly longer ; the vertex punctu- 

 lated ; the rostrum thickly covered with hairs to the apex ; the 

 antennae inserted before the middle of the rostrum, the basal 

 joints black or piceous, the clava ovate ; the thorax suhcylindrical ; 

 and the elytra black (never blue, obscure green or greenish black). 

 The female differs in having the rostrum sparingly covered with 

 hairs to the tip, and the antennse inserted nearer the middle of 

 the rostrum. 



Specimens of this insect were sent by Mr. Waterhouse and 

 myself to M. Schonherr, which were named Ap. mecops by that 

 author. 



This species is very abundant in the south of England, and is 

 found upon the rest-harrow {Ononis arvensis) from June to Oc- 

 tober. It is extremely local in Yorkshire, but very plentiful when 

 found.
