REPORT ON ZOOLOGY, MDCCCXLIII.

venustus, nigromaculatus, Silbermanni, 4- notatus, zebra, albofasciatus, nitidus.Phonius and Derostenus are given as new genera; the former, however, isproperly identical with Cleronomus, Kl.; the latter, which the author is in-clined to place with Eurypus (which is not one of the Clerii at all,) accord-ing to the characters given by him, belongs to the form of Tillus withsimply toothed claws, and can scarcely be said to differ from Cleronomus.

Mannerheim (Bull. Mosc. p. 248) describes a new species, Clerus eximius,which was caught in a ship that had sailed from California , and probablybelonged to that country.

Lucas reared in Paris , out of brushwood from Algiers , Opilus dorsalis( Notox. id Dej., hitherto known only as from Senegal, ) and Cylidrus agilis,Luc. (Ann. d. 1. Soc. Ent. d. Er. 2 ser. i, 24.) The former may probablybe Notox. dimidiatus, Lap., the latter appears to be nothing else than Cy-lidrus albofasciatus ; and, in fact, the variety with black face, figured byCharpentier.

Suffrian has made known (Ent. Zeit. s. 123) that Cylidrus albofasciatus( Tillus id., Charp., St.) has been, lately, again found in Germany , by theLev. Pastor Schmitt, in a pine wood, near Mayence .

Ptiniores. —Schilling (Arb. u. Veriind. d. Schles. Gesellsch. Yr. I. 1843,p. 175) has obtained from the rock-salt mines of Wieliczka , in Galicia , frag-ments of salt with Coleoptera , which proved to be Ptini. The author regardsthem as a new species, which he names Ptinus salinus. We have long sincereceived rock salt from the same locality with Coleoptera , which were nothingbut Ft. crenatus, E., and which probably inhabited, with their lance, not thewoodwork of the mines, but the human excrements.

Mannerheim (Bull. Mosc. p. 93) found in Einland two new species ofAnobium; the one, A. excisum, allied to A. denticolle, Pz„ the other, A. ex-planatum, approaching A. molle.

The history of the metamorphosis of Xyletinus hedera, Duf. ( Icevis , Latr.,Cardui, Dej.) has been detailed by Leon Dufour (Ann. d. 1. Soc. Ent. d. Fr.,2 ser. i, p. 321). The larva inhabits dry ivy branches.

■ Klingelhofer (Ent. Zeit. s. 86) has communicated his observations withrespect to the occurrence of Apate varia.—hwss, (Ann. d. 1. Soc. Ent. d.Er. 2 ser. i, p. 25) has reared out of brushwood three Algerian species, whichhe describes as new : A. rufwentris, nigriventris, Tmmeralis. The last occursalso in the South of Europe , and is enumerated under the same name inDejean’s catalogue ; the second is figured in Olivier’s Entom. as Bostrichuscapucinus, and is also confounded with it in -the text, but it is neither avariety of A. capucina, nor an independent species, but a variety of A.luctuosa.

Silphales. —Klingelhofer (Ent. Zeit. s. 88) communicates the interestingobservation that Necrophorus germanicus attacks and drags away the livingGeotrupes stercorarius, and Dr. Schmidt has confirmed the fact. I also have
