144 REPORT ON ZOOLOGY, MDCCCXLIII. 



and the latter G. siculus, Dahl., (G. Douei, Gory.) The author is also in 

 error in referring to the labruni, one of the lateral processes of the mandible 

 in the male of the latter. 



Westwood (Proceed. Ent. Soc. p. 68) has added three new species to his 

 genus Silphodes (Report for 1841, p. 226) : S. indica, from the East Indies; 

 inudagascariensis, from Madagascar, ditbia, locality unknown. 



TROGIDES. Two new species from Angola are, Trox raricosus, and 

 radula, Erichs. (1. c.) 



DYNASTIC,*:. Some MexicanDyuastidse have been illustrated by Chevrolat. 

 (Gueriu, Mag. de Zool.) Scaralaus (Megasomd) Elephas, E. (pi. 109, 110) 

 is found in Mexico, and Central America is thus determined for its habitat. 

 According to the author's account, it was found on the sea-shore, in Man- 

 grove thickets. The Prussian travellers in Guatemala, M. Eellechner (R. 

 Counc.) and Dr. Muller, however, have communicated orally that they ob- 

 tained it only on Mahogany trees. Dynastes Hyllus, Chevr. (pi. Ill, 112), 

 has been already well figured by Panzer as Sc. Iphiclus. Enema, Lupercus, 

 Chevr., and R Endymion, Chevr., are only described, the former is merely 

 a variety of E. Pan, without a tooth on the horn ; the variety occurs in 

 Brazil also, as does the primitive species in Mexico. 



Sturm (Catal. pi. ii, fig. 5), has given an excellent figure of the Golqfa 

 Porteri, Hope, under the name of Scarabaeus Petiveri, Er., I must here re- 

 mark, that when I noticed in the Report for 1837, that old Petiver had 

 already figured tliis insect, and when I proposed that it should be named 

 S. Petiveri, I believed that it differed from Geotr. a-geon, E. ; I am now, how- 

 ever of opinion, that the species which is at present considered to be 

 G. agcon, is not such, and with respect to this it is to be well weighed) 

 that it is indigenous at Lima, a region of the productions of which 

 Eabricius and Drury knew nothing, but that the G. tegeon of Eabri- 

 cius and Drury must be regarded as a small male of G. Porteri, Hope, with 

 slightly developed horns. The description by Eabricius is extremely good, 

 but Drury's figure very unsatisfactory, and the more so, that he has re- 

 presented the insect with the legs of a Stag-beetle. 



RUTELIDJE. Auumber of Mexican species belonging to the genus Chrysina, 

 Kirby, have been figured by Sturm (Catal. pi. iii), under the following 

 names : Pelidnota eeruginosa, amana, modesta, latipennis, laniventris, psitta- 

 cina, ornatlssima. The first two, as well as the fourth and fifth, must, how- 

 ever, be united as male and female ; the last but one is figured as CJir. au- 

 ripes, by Gray, (in Cuvier's Anim. Kiugd. by Griff), and the last described - 

 (poorly enough) by Hope, as Pel. Adelaida.
