Mr. J. Walton on the genus Apion. 333 



carhonarium of Germar, which he has sunk in his ' Manual ' as a 

 variety oi Ap, Sorbi, but with a note of interrogation; and the 

 error has not been corrected, as the name still stands in Curtis^s 

 ' Guide^ and in Stephens's ^ Nomenclature/ 



Gyllenhal has erroneously referred the male to Cure, aterrimus 

 of Linnaeus : see notes on Ap. marchicum. 



This fine species appears to be rare in the south of England. 

 Mr. S. Stevens captured a few specimens of both sexes at Bury- 

 hill near Arundel ; Mr. Wollaston found the female abundantly 

 amongst moss and dead leaves near Cambridge, and what is re- 

 markable, without a single male occurring ; I have also met with 

 the female very plentifully under the same circumstances in woods 

 and hedges near Knaresborough in Yorkshire in June, and both 

 sexes in company in the same neighbourhood on the black thorn 

 {Prunus spinosa) in September. According to my experience, the 

 males oi Ap. subulatum are very rarely found with the female, and 

 when they occur together, the number of females is much greater 

 in proportion than the males. It is difficult to assign a cause for 

 these anomalies. 



40. A. Ervij Kirb., Gyll., Germ., Steph., Schonh. 



— {^) Lathyri, Kirb., Steph. 



Mr. Kirby confounded the sexes of this insect, and recorded 

 Ap. Lathyri as a distinct species ; Gyllenhal afterwards defined 

 the sexual characters, and cited Ap. Lathyri of Kirby as the male 

 of Ap. Ervi ; British writers have subsequently, upon the author- 

 ity of the latter author, upheld the name ; I have however pub- 

 lished* evidence of their identity which I need not repeat here. 



This is a common species, widely distributed, and occurs al- 

 most everywhere on the Lathyru^ pratensis from June to October. 



41. A. punctigerum, Germ., Gyll., Steph., Schonh. 



— sulcifrons, Kirb., Staph., not Herbst. 



— punctiger, Payk., Gyll. vol. iii. 



I have seen a foreign specimen of Ap. sulcifrons of Herbst in 

 the possession of Mr. Waterhouse, which is undoubtedly distinct 

 from the present species, and has not yet been discovered in 

 Britain. 



I found this insect abundantly in the north, and also near 

 Dover on Vicia sepium, in company with Bj^uchus seminar ius, in 

 June last. 



42. A. Spencii, Kirb., Germ., Steph., Schonh. 



— (var. /3, y.^foveolatum, Kirb., Steph. 



— intrusum, Gyll., Steph. 



— columbinum, Steph., not Germ. 



The description of Ap. foveolatum by Kirby is taken from a 

 * Ent. Mag. v. p. 13.
