Mr. J. Walton on the genus Apion. 337 



which is now in the collection of Mr. Kirby, and the other in that 

 of Mr. Stephens ; these are the only specimens known. 



49. A.flavipes, Fab. (1781), Herbst, Kirb., GylL, Germ., Steph., 



Schonh. 

 Common on the white or Dutch clover {Trifolium re'pens)^ 

 Mr. Kirby. 



50. A. nigritarse, Kirb., Germ., Steph., Schonh. 



— Waterhousei, Schonh. 



The typical example of the last-named insect being in the ca- 

 binet of Mr. Waterhouse, I have had ample opportunity of exami- 

 ning it ; it is doubtless a female variety of the present species, 

 having the tibise obscure testaceous. 



Found rather abundantly on various plants j which renders its 

 habitat uncertain. 



h\, A. assimile, Kirb., Germ., Gyll., Steph., Schonh. 



— (var. b.) flavipes, Gyll. vol. iii. 



Taken occasionally in profusion from April to October in red 

 clover fields, pastures, meadows, and on hedge-banks, frequently 

 in company with the two following species {Ap. Fagi and Ap. 

 Trifolii). 



52. A. Fagi, Linn., Kirb. 

 Cure. Fagi, Mus. Linn. 

 A. apricans, Herbst, Germ., Gyll., Steph., Schonh. 



— Fagi, Mus. Kirb. 



— fiavifemoratum, Kirb., not Herbst. 



The law of priority requires that the name given by the illus- 

 trious naturalist should be restored to this species. 



Mr. Kirby has demonstrated* that the original specimens now 

 preserved in the Linnsean museum are "beyond all question'^ 

 the true Cure. Fagi of Linnseus. I have recently rigorously re- 

 examined and compared these specimens with all the yellow- 

 legged Apions that are liable to be confounded with them, and I 

 can now affirm, without the least hesitation or doubt, that they 

 are two immature males of Ap. aprieans of Herbst : the form of 

 the rostrum being nearly straight; the pale yellow basal joints of 

 the antennse, their shallow subremote punctures on the disc of 

 the thorax, the pallid or pale yellow trochanters and femora, 

 distinguish them from all the other allied species. 



Ap. Fagi of Kirby is described by him from the above-named 

 Linnsean examples. There is an insect in the Kirbian collection 

 of Apions with the name " Fagi " ; it is fastened upon a piece of 

 paper with gum, and compressed to imitate the Linnsean speci-
