Mr. J. Walton on the Genus Apion. 4S1 



bescens of Kirby, and therefore distinct from the present species. 

 That the two are distinct I have further evidence, for Dr. Germar, 

 to whom I sent specimens of Ap. Curtisii, and whose attention 

 I particularly directed to the points of difficulty^ informed me 

 that it was a new species and not in his collection. The Apion 

 seniculus, Curtisii and pubescens are nearly allied. Ap. pubescens 

 is distinguished from Ap. Curtisii by its broad convex form, its 

 more pubescent body, and in being less glossy; the head is broader, 

 and has a concavity between the eyes ; the rostrum is less glossy, 

 and is slightly pubescent ; the antenna has the third and fourth 

 joints longer. 



Ap. seniculus differs from Ap. Curtisii in being larger and pro- 

 portionably longer, in having the body distinctly clothed with 

 whitish hairs, the head narrower in proportion, and the rostrum, 

 in both sexes, much longer, but more strikingly so in the female : 

 the elytra are oblong-ovate. 



Ap). Curtisii has been taken on the sea-coast near Little Hamp- 

 ton amongst grass, in the month of August, by Mr. S. Stevens; 

 and also by myself, in profusion^ near Arundel, in the same month. 



14. A. violaceum, Kirb., Gyll., Steph., Schonh. 



This species, which is widely distributed, is found upon the 

 common dock {Rumex obtusifolius) in many parts of England 

 dm'ing the spring and autumnal months. 



15. A. Hijdrolapathi, Marsh., Kirb., Gyll., Genn., Steph., Schonh. 



This species is closely allied to the preceding, and is rather diffi- 

 cult to distinguish ; but the head is evidently broader ; the rostrum 

 shorter, and thicker at the base ; the thorax instead of an impressed 

 point has a longitudinal furrow. 



This, like the last species, is found in various parts of England. 

 I have taken it both on the common dock and the great water- 

 dock {Rumex Hydrolapathum) in the months of June and Sep- 

 tember. 



16. A. frumentarium, Linn., Payk. (1792), Gyll., Schonh. 

 — heematodes, Kirb., Germ., Steph. 



In the nomenclature of this species I have followed the Swedish 

 entomologists, because that species which we call the Ap. frumen- 

 tarium of Linnaeus is not a native of Sweden ; there is no speci- 

 men in the Linnrean cabinet, and the description is too short in 

 the ' Fauna Suecica ' to decide the question ; the term " longi- 

 rostris " is also used by Linneeus to define Cure. Pruni, placed by 

 him in the same section ; the Cure, frumentarium of Fabricius, the 

 next oldest w^'iter, is equally if not more difficult to determine ; 

 according to Gyllenhal (who had better opportunities of judging
