Mr. J. Walton on the genus Rhynchites. 85 



6. R. conicus, Illig. (1801 — 1806), Germ., Sclionh. 



— AUiaricB, Steph. 

 Cure. AUiaritB, Marsh. 



Att. Alliariee and nanus, Mus. Kirb. 



I have tlie authority of Schonherr and Germar for applying 

 the name of conicus to this species. To both of these authors I 

 have sent specimens. I have found this species in white-thorn 

 hedges in the months of June and October. 



7. R. pauxillus, Germ. (1824), Schonh., Steph. Man. 



— airocieruleus, Steph. 111. 



Of R. pauxillus of Germar I possess five specimens sent me by 

 that author. 



" This species (No. 7) is distinguished fromi?. minutus of Steph." 

 (Dr. Germar observes in his letter to me) " by the thorax being 

 more deeply punctm-ed, its dorsal channel distinct, and by the 

 hairs covering the body being longer and more erect." To these 

 characters maybe added a difference in the rostrum, \\z. this or- 

 gan is more cm*ved in the present species than in the minutus. I 

 have found the R. pauxillus on the white-thorn hedges at Swans- 

 combe near Gravesend, in the months of May and June. 



8. R. germanicus, Herbst, 1797. Mus. Herbst. 



— minutus, Gyl. (1813), Steph., Schonh. 

 Cure, nanus, Marsh? 1802. 



Att. ceneovirens, Mus. Kirb.* 



Of this species (No. 8) I have foreign specimens sent me by 

 Schonherr and Germar under the name minutus. I have also two 

 English specimens which I forwarded to Germar, returned to me 

 mth the same name. From this latter author I have the follow- 

 ing note regarding the present insect : "R. minutus, Schonh. ; 

 according to the cabinet of Herbst, it is the true germanicus." 



This is a very common species : its time of appearance is in the 

 month of June. 



9. R. Alliari(B, Payk. 1792, Gyl. 1813. 



— interpunctatus (Wilkin MSS.), Steph. 1831. 



— megacephalus, Schonh. 



I sent this species both to Schonherr and Germar : the former 

 informs me it is his R. megacephalus ; from Germar I have the fol- 

 lowing note : '^R. interpunctatus, Steph. — this name would be re- 



* In Sclionherr's 'Syn. Ins.' vol. i. p. 233, 1833, Cure, esneovirens of 

 Marsham is cited as a S3'iionyni to No. 33, R. Fraijarice (" Teste Dom. 

 Kirby";. It is evident from this that Kirby sent Gyllenlial a true Marsliamian 

 type (a blue variety) of the (Envovirena, and judging: from the only two ex- 

 amples of No. 8 now in Mr. Kirby's cabinet, which are blue-green varieties, 

 he seems to have considered this species the same as the ceneovirens. 



Gyllenhal (which is very singular) made precisely the saine error : see 

 ' Ins. Suec' iii. p. 27, 1813, which he corrected in Schoiiherr's ' Syn. Ins.,' 

 as above, twenty years afterwards.
