INSECTA. 141 



never found N. germanicus in carrion, but always in the neighbourhood of ex- 

 crement. 



New species are, Necrophorus niffrita, M., from California ; N. maritimns, 

 Eseh., from Sitka ; Silpha cervaria, californica, Esch., from California ; Necro- 

 pMlus Jiydrophiloldes, Esch., Catops cadaverimis, Esch., from Sitka; by Man- 

 nerheim. (Bull. Mosc. p. 251.) 



Necrodes analis, Chevrolat (Guerin,Mag. de Zool. Ins. pi. 107, 108, p. 26), 

 from Mexico, appears to be SilpJia cayennensis, St., discicollis, Brull., which is 

 diffused throughout South America. 



HISTERES. New species of this family arc, Ulster heros, Erichs. (1. c.), 

 from Angola ; Saprinns eqxestris, from the Cape de Verd Islands (not from 

 Angola), and S. imbricatus, from Angola, id. (ib.) ; S. calif ornicus, sulcifrons, 

 Mauucrh. (Bull. Mosc. p. 259), from California. 



Abrccm rombophonts, Aube (Ann. d. 1. Soc. Ent. d. Er., 2 ser. i, p. 75, pi. 

 1. 4, fig. 2), from Paris, resembles A. nigricornis, from which it differs chiefly 

 in the pale club of the antennas, and the dilated, externally rounded an- 

 terior tibiae. 



TRICHOPTERYGIA. Heer (Ent. Zeit. p. 39), from the examination of the 

 structure of Trichopteryx, has concluded that it is to be ranked with the 

 Staphyliui as a separate group, " Ptllina" My own researches, viz., with 

 respect to the oral organs, correspond but little with those of the author ; 

 I observe, also, so many peculiarities, that the formation of a separate 

 family becomes justifiable. As an account of my researches will very 

 shortly appear in my German Eauna, farther discussion here seems to be 

 superfluous. The valuable inquiries of the author with respect to the plica- 

 tion of the wings and the composition of the abdomen in the Coleoptera, 

 which are communicated on this occasion, have been before referred to, 

 (p. 121.) 



Mannerheim (Bull. Mosc. p. 84) has found a new species, Trichopteryx 

 piclcornls, [v. Report 1845], in the Ant hills of F. rufa. 



NITIDULARI^;. Nitidula terminata, Mannerheim (Bull. Mosc. p. 95), col- 

 lected in Finland, about the sap which drops from the Birch, differs from N. 

 limbata, F., in its less size, and in the prothorax and elytra having a 

 broader margin. Mannerh. (ib. p. 255, 300) gives as new species, Strongylus? 

 tinctm, from California; Nitidula convexiuscula, ambigua ; RhizopJiagus dimi- 

 dlatus, from Sitka ; Trogosita chlorodia, viridici/anea, from California ; T. 

 pusllllma, from Sitka. 



CRYPTOPHAGID^E. Mannerheim (Bull. Mosc. p. 256) has enriched Crypto- 

 phagm with two new American species : Cr. californicus, from California ; 

 and C. quadridentatus, from Sitka. 



DERMESTINI. A new genus, Telopes, is described by Redtenbacher, (Rus- 

 segg. Reis. i, s. 984) ; it differs from Attayenus in the shortness of the body,
