148 REPORT ON ZOOLOGY, MDCCCXLIII. 



Tenebrionidae. With respect to Westwood's paper, Description of some 

 Coleopterous Insects from Tropical Africa, belonging to the section Hete- 

 romera (Trans. Zool. Soc. iii, p. 207), what is most important has been 

 already noticed in last year's Report from the Abstract given in ' Proceed. 

 Zool. Soc.' (Transl. Report, p. 197 (241).) At present only some remarks 

 will be made. The CMroscelis digitata figured by King, corresponds with 

 Ch. bifenestretta of the author. Nyctobates cot/fusmis, as the author correctly 

 surmises (p. 221), Helops simiatus, E. The genus Oycoosoma is identical 

 with Amatodes, Dej., and 0. granularis, Westw., is a species nearly allied to 

 Pirn, gemmata, E. 



Three new genera of this group, from California, have been instituted by 

 Mannerheim. (Bull. Mosc. p. 279.) All three nearly related to Upis, but are 

 apterous. 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 spicula?. A new 

 species, C. caraboides. 2. Coelocnemis (also figured in Guer. Mag. de Zool., 

 1844, Ins. pi. 133), has the clypeus anteriorly cut off straight, the 

 femur deeply hollowed beneath, all the tibiae with a deep longitudinal groove 

 on the inside. Two new species, C. catifornica and C. dilaticolUs. 3. Cib- 

 delis, clypeus anteriorly slightly rounded, legs without distinction : a new 

 species, C. BlascJiMi. New species -(from the same locality), are Nyctobates 

 serrata, and inermis, Esch. (Ib. p. 284.) 



Tenebrio snbntgosns, Dej., from Senegal, Guinea, and Angola, has been 

 described by the Reporter (I.e.) 



Diaperiales. The liistory of the metamorphosis of Boletophagus (Eledona) 

 agaricola, and of Diuperis Boleti, has been described by Leon Dufour, (Ann. de 

 Sci. Nat. x, pp. 284, 290, tab. xii.) Thelarva? have an essential resemblance 

 with Tenebrio (with which I have formerly compared both, in the 8th annual 

 issue 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, and 

 there undergo their metamorphosis, after closing the opening with fragments. 



New species are, Uloma pidla, Erichsou (1. c.), from Angola, and Phaleria 

 picta, Esch., Mannerh. (Bull. Mosc. p. 277), from Sitka. 



Helopii. Along with a new species, Helops calif ornicus, Esch. Mannerheim 

 (Bull. Mosc. p. 286) has founded a new genus, EitcypJnis, in which the head 

 is retracted beneath the prothorax, the elytra arc much arched, and a mem- 

 branous appendage is placed beneath the antepenultimate tarsal joint ; the 

 species, Eucyplius liybosoroides 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 Trictenotoma. A new species, H. mandibularis, from 

 Angola, even resembles Tnctenotoma in the widely projecting mandibles.
