INSECTA. 145 



Europe and the adjacent islands, and also in North Africa, there are here 

 enumerated 16 species : A, clypeus slightly or not at all emarginate : 



1. E. Bedeaui, Er., frequent in the Bay of Cadiz, in the sand dunes, iu Fe- 

 bruary; as is the case with Cebrio, sexual congress takes place only during a 

 shower of rain, at other times the insects conceal themselves in the sand ; 



2. E. mauritanica, R., from Algiers ; 3. E. inalaceensis, from Malaga ; 

 4. E. numidica, from Algiers ; 5. E. longitarsis, 111., Er. ; 6. E. hiemalis, Er. ; 

 7. E. obscura, Gene, Er. ; 8. E. dilatata, Er. B, clypeus anteriorly more or 

 less deeply emargiuate : 9. E. granatensis, from Granada ; 10. E. barbara, 

 from Algiers; 11. E. sardoa, from Sardinia; 12. E. hispalensis, from Seville; 

 13. E. byzantina, from Turkey in Europe; 14. E. clmrianensis, from Malaga; 

 15. E. carteiensis, from the shore opposite Gibraltar (San Roque) ; 16. E. gra- 

 cilis, Waltl., Er. The latter coincides with the E. byzantina of the author. 



With reference to the position of Elaphocera, the author thinks that the 

 group of Pachypodes, instituted by me in the ' Entomograph.' is not a natural 

 one, and he considers the more imperfect condition of the mouth, only as a 

 secondary character ; he says, " that for the same reason Sesia apiformis must 

 also be separated from Sesia, and made into a distinct genus." This has 

 been long done ! and when the author states that Elaphocera, with Leoc&ta,, 

 Lagosterna, Dasysterna, &c. forms a natural group, it is all in pettu, for he 

 assigns no characters to the group, nor even its boundaries. 



In a note, Rambur (1. c.) describes two supposed new genera, which in his 

 opinion come next to Elaphocera. The one, however, Dasysterna, Dej., 

 has been already instituted by me (in Mor. Wagner's Reisen in Algier) 

 as Phlexis, and is probably also identical with Tanyproctus, Eald. ; at least 

 (although Faldermaun's description is altogether useless, owing to the omis- 

 sion iu it of the most essential points, number of lamellae of antennae, &c.) the 

 species described by me (1. c.) as Phi. Ecersmanni, has been sent us from St. 

 Petersburgh, as Tan. scarabtfoides, Eald. Of the three proposed species I re- 

 gard, 1. D. barbara, Dej., from Barbary, as Melol- hirticollis, Fab. ; 2. D. 

 canariensis, Ramb., is probably one of the three Canary species described by 

 Bridle, which I have noticed in the Report for 1840, p. 174, as species of 

 Plilexis ; 3. D. ReicJiii, from Athens, is, however, new. The second genus, 

 Art la, differs from the former only in all the tarsi in the female being simple, 

 whilst in the former the anterior tarsi of the female are dilated. Of this 

 genus there is a new species, A. cartliag'mensis, from Tunis, 



A new genus, Metascelis, allied to Pachypiis, has been instituted by West- 

 wood (Proceed. Ent. Soc. p. 68) ; apterous, elytra gaping at the apex, 

 clypeus entirely covering the mouth, antenna? short, 9-jointed, the fourth 

 joint short, dilated inwards, the fifth and sixth joints with shorter, the seventh 

 to ninth with longer lamellee ; blade of maxillae stunted ; sides of prothorax 

 rounded, hind legs rather short and very thick. M. JlextUs, locality un- 

 known. 10
