Mr. J. Walton on the Germs Apion. 449 



scription. I possess foreign specimens of the true Apion brevi- 

 rostre of Herbst sent me by Dr. Germar, and these are very di- 

 stinct from the present species. 



8. A. minimum^ Herbst, GylL, Germ., Schonh., Steph. Man. 



— velox, Kirb., Germ., Staph. 111. 

 — foraminosum, Schonh. 



Dr. Germar has sent me German specimens under the last of 

 the above names, with a remark that they do not differ from Apion 

 minimum : in this opinion I perfectly agree. 



Mr. Smith found this rare species in Turner^s Wood, Hamp- 

 stead, upon the willows in the month of May. Mr. S. Stevens 

 and myself have also taken it somewhat plentifully in the same 

 locality. 



9. A. simile, Kirb., Germ., Steph., Schonh. 



— super ciliosum, Gyll. (vol. iv,), Schonh. 



Specimens of both sexes of the Apion simile were sent by me 

 to Schonherr, and returned by that author with the name simile 

 but with a note of doubt. The insect from which Schonherr drew 

 up his description of Apion simile was sent to him by Mr. Water- 

 house, and was correctly referred to the Ap. simile of Kirby. An 

 opportunity of examining the original typical specimens from 

 which both Schonherr and Kirby made their descriptions has 

 quite satisfied me on this point ; according to Germar, Ap. simile 

 of Kirby is identical with the Ap. superciliosum of Gyllenhal and 

 the Ap. triste of Germar*. 



This species has been found at Birch and Coombe Woods, at 

 Shirley Common near Croydon, Yorkshire, and in other places, 

 the latter end of June and the beginning of July, always on the 

 birch-tree [Betula alba). 



10. A. tenue, Kirb., Germ., Steph., Schonh. 



I found this insect plentifully in the Charlton sand-pits on 

 the Trifolium officinale in the months of June and July; Mr. S. 

 Stevens has taken it by sweeping, at Mickleham, Gravesend, 

 Arundel, and other places, in the months of April, May, June, 

 August and September. " 



11. A. seniculuSj Kirb., Germ., Gyll., Steph., Schonh. 



— tenuis, Gyll. (vol. iii.). Germ. 



— (?) pusillum, Mus. Steph. not Germ. 



— ( cT ? ) pubescens, Schonh. 



Not having had an opportunity of examining the Kirbian col- 

 lection, Mr. Waterhouse formerly supposed the present species 

 was the true Apion pubescens of Kirby, and in forwarding it un-
