450 Mr. J. Walton on the Genus Apion. 



der that name to M. Schonherr, has given rise to an error in the 

 work of that author, M. Schonherr having in fact drawn up his 

 description under the head ''Ap. pubescens, Kirby*/^ from Mr. 

 Waterhouse's specimens ; and these I find upon examination were 

 the Apion seniculus of Kirby, a nearly allied but certainly distinct 

 species. The Apion elongatum of Germar is quoted by Schonherr 

 as synonymous with the Ap. seniculus of Kirby. I have now in 

 my possession a specimen of the Ap. elongatum from Germar, and 

 am quite satisfied that it is a distinct species. I have found Apion 

 seniculus very plentifully near Knaresborough, in Yorkshire, by 

 sweeping in fields of grass dming the months of May and June ; 

 it is less common near London. 



12. A. pubescens, Kirb., Steph. 



— civicum, Germ. 



— Salicis (Chevr. in Litt.), Schonh. 



The description given under the name of Ap. pubescens by 

 Schonherr t was taken from specimens forwarded to that author 

 by Mr. Waterhouse, which, unfortunately, were not the jmbes- 

 cens of the original describer of the species ; they were undoubt- 

 edly the Apion seniculus of Kirby : of the true Apion pubescens I 

 sent six examples, including the sexes, to Schonherr, who observed 

 that they were new to his collection, but were the species he had 

 described as Ap. pubescens of Kirby ! 



I likewise forwarded several examples of Ap. pubescens to Dr. 

 Germar, who stated that they are without doubt specifically 

 identical with his Ap. civicum. I possess an insect sent me by 

 Chevrolat of Paris, under the name of Apion Salicis of Chevi'olat 

 and Schonherr, which is, very distinctly, a true Ap. pubescens of 

 Kirby. 



I captured Ap. pubescens in great numbers on the east side of 

 Hastings on the 4th of August, upon willows growing in hedges, 

 and also in Yorkshire amongst grass. Mr. S. Stevens has taken 

 it at Birch Wood, Ai-undel, and Hammersmith, in the months 

 of August and September. 



13. A. Curtisii (Kirb. MSS.), CurtisJ. 



Specimens of the true Ap. Curtisii which I sent to Schonherr 

 were regarded by that author as the Ap. civicum of his work and 

 of Gyllenhal. The insect described under the last-mentioned 

 name by Gyllenhal had been received from Schuppel as the Ap. 

 civicum of Germar, and judging from the description in the 

 ' Insecta Suecica ' (vol. iv. p. 544), I am inclined to believe 

 that Ap. civicum of Gyllenhal is synonymous with the Ap, pu-
