446 Mr. J. Walton on the Genus Apion. 



1. Apion Cracc(Bt Linn., Herbst, Kirb., Gyll., Germ., Steph., 



Sclionh. 

 Cure. Craccce, Mus. Linn., Marsh. 

 Ap. ((^) ruficorne, Herbst, Kirb., Germ., Steph. 



About the middle of October last I met with this species at 

 Shirley Common near Croydon, in great abundance upon the 

 oak and ash trees, but I have never found it upon the Vicia 

 Cracca. Mr. Waterhouse however informs me that he has reared 

 several specimens from the pods of that plant. 



2. A. Pomona, Fab., Gyll., Germ., Steph., Schonh. 

 Cure, ccerulescens. Marsh. 



— (|S. var.) glaber, Marsh. 

 Ap. ccerulescens, Kirb. 



In the first week of August last I collected a number of seed- 

 pods of the Vicia sepium near Hyde in the Isle of Wight, and 

 some time after, upon opening the paper in which they were in- 

 closed, I found several specimens of Apion Pomonce had made 

 their escape from them ; in other pods there were small perfora- 

 tions, as if made with a pin, and in these I found the living in- 

 sect. Mr. Waterhouse and myself have beaten the present species 

 out of the juniper bushes at Birch Wood in considerable abundance 

 in the month of May. 



3. A. subulatum, Kirb., Germ., Gyll., Steph., Schonh. 



— ( ^ var. /3.), Kirb. MSS. et Mus. 



— Marshami ( $ ), Steph. (cJ), Schonh. 



— ( c? ) I'^a^ft^ew, Curt, not Germ. 



I have again examined the two insects in the cabinet of Mr. 

 Stephens imder the name of Apion Marshami ; they have the 

 rostrum attenuated before the antennse, neither filifoi^m, nor gib- 

 bous beneath : they are certainly two female varieties of this spe- 

 cies. The description of Apion Marshami by Schonherr was 

 drawn from a specimen sent to that author by Mr. Waterhouse, 

 which being now in the last-mentioned entomologist's possession, 

 I have had an opportunity of examining and comparing it with 

 others : it is undoubtedly the male of Apion subulatum. I may 

 here mention that I have in my possession a species of Apion (the 

 Ap. opeticum of Markel) sent me by Dr. Germar, which he had 

 supposed was the Ap. Marshami of Schonherr ; it is certainly very 

 nearly related to Ap. subulatum, but is however readily distin- 

 guished by the form of the rostrum, which is stouter at the base, 

 distinctly gibbous beneath, and filiform in front of the antennse. 

 I possess specimens of Apion jjlatalea sent me by Dr. Germar, 

 which I find have no affinity to oui* Ap. subulatum, and are of a 

 species not hitherto found in this country. 



I have never met with Ap. subulatum in abundance, but have
