REPORT ON ZOOLOGY, MDCCCXLIII.

Tenebrionidse.—With respect to Westwood’s paper, Description of someColeopterous Insects from Tropical Africa, belonging to the section Hete-romera (Trans. Zool. Soc. iii, p. 207), what is most important has beenalready noticed in last year’s Report from the Abstract given in ‘ Proceed.Zool. Soc.’ (Transl. Report, p. 197—(241).) At present only some remarkswill be made. The Chiroscelis digitata figured by Klug, corresponds withCh. bifenestrella of the author. Nydobates confusus is, as the author correctlysurmises (p. 221), Helops simiatm, P. The genus Ogcoosomc is identicalwith Amatodes, Dej., and 0. granulans, Westw., is a species nearly allied toPirn, gemmata, P.

Three new genera of this group, from California , have been instituted byMaimerheim. (Bull. Mosc. p. 279.) All three nearly related to Tipis , but areapterous. 1. Centrioptera (also figured in Guer. Mag. de Zool, 1843, Ins.pi. 126), has the clypeus rounded anteriorly, the femur deeply hollowed be-neath, the elytra posteriorly with three lateral rows of spiculse. A newspecies, C. camboides. 2. Coslocnemis (also figured in Guer. Mag. de Zool.,1844, Ins. pi. 133), has the clypeus anteriorly cut oif straight, thefemur deeply hollowed beneath, all the tibise with a deep longitudinal grooveon the inside. Two new species, C. californica and C. dilaticollis. 3. Cib-delis,. clypeus anteriorly slightly rounded, legs without distinction : a newspecies, C. Blaschkii. New species (from the same locality), are Nydobatesserrata, and inermis, Esch. (Ib. p. 284.)

Tenebrio subrugosus, Dej., from Senegal , Guinea, and Angola , has beendescribed by the Reporter (1. c.)

Diaperiales. The history of the metamorphosis of Poletophagus (Eledona )agaricola, and of Diaperis Boleti, has been described by Leon Dufour, (Ann. deSei. Nat. x, pp. 284, 290, tab. xii.) The larvae have an essential resemblancewith Tenebrio (with which I have formerly compared both, in the 8th annualissue of these Archiv . i, p. 366); in their mode of life they each present this pecu-liarity, that they bite out a round portion of the fungus, and hollow it out, andthere undergo their metamorphosis, after closing the opening with fragments.

New species are, Uloma pulla, Erichson (1. c.), from Angola , and Phaleriapicta, Esch., Mannerh. (Bull. Mosc. p. 277), from Sitka.

Helopii.—Along with a new species, Helops californicus, Esch. Mannerheim(Bull. Mosc. p. 286) has founded a new genus, Eucyphus, in which the headis retracted beneath the prothorax, the elytra are much arched, and a mem-branous appendage is placed beneath the antepenultimate tarsal joint; thespecies, Eucyphus hybosoroides is also from California .

The Reporter (1. c.) has described the genus Himatismus {Imatismus,Dej.), and has shown that it is closely related on the one side with Epitragus,and on the other with Tridenotoma. A new species, H. mandibularis, fromAngola , even resembles Tridenotoma in the widely projecting mandibles.
