TWO NEW SPECIES OF BEETLE. 27 



following year named by Linnaeus, Scarabceus Goliatus. 

 (Mantissa Altera p. 530). Lamarck included in his genus 

 six species, all of which had previously been described. 

 These are, Gol. Africanus, 1 Cacicus, 7 - Polyphemus,* bifrons, 4 

 micans, b and marginalise 



Weber, about the same time as Lamarck, after his descrip- 

 tion of the Cetonia Ynca, remarks (Obs. Entomol. p. 67,) 

 " Forte Ynca, Goliata, Cacicus, Polyphemus, &c, novum 

 constituunt genus ;" and Fabricius immediately after ex- 

 pressed the same opinion. (Syst. El. II. p. 136.) 



Many other species have been added to this fine group of 

 beetles by subsequent authors, and the Cetonia quadrimacu- 

 lata of Oliv., (tab. viii. fig. 73, p. 30,) and Scarabceus tor- 

 quatus of Drury, (111. pi. 44, fig. 1.,) have been since ascer- 

 tained to be females of species of the genus. The male of 

 the last mentioned has been lately brought from Sierra Leone 

 by Mr. Strachan, and an excellent figure and description 

 have been given of it by Mr. Waterhouse, in the last number 

 of this Magazine. The male of the GoL quadrimaculatus is 

 in the possession of Mr. MacLeay. 



I shall now confine myself to that section of Goliathus 

 which Mr. MacLeay has called Smithii, in his lately pub- 

 lished elaborate memoir. 7 It is characterized by the gene- 

 rally metallic colour of the species composing it, which have 

 " the elytra wider at the base, the body very depressed, the 

 thorax nearly truncated behind, or at least only slightly emar- 

 ginate to receive the scutellum. The males have almost al- 

 ways the anterior tibice denticulated on the inside." (Mac- 

 Leay.) 



In one division the males have the anterior tibice externally 



1 Afterwards changed to Gol. giganteus in the 'Hist. Nat. des Anim. sansr 

 Vert.' iv. p. 580. Fabricius, Olivier, and Latreille, as well as Lamarck, re- 

 garded the insect figured by Drury in 1782, (' Illust.' iii. pl.xl.) and named 

 in his index Scar abacus Goliatus, as a mere variety. — Subsequent authors 

 are of opinion that it is distinct ; and Mr. Westwood has named it Golia- 

 thus Drurii in his new edition of Drury's ' Illustrations.'

 tab. 22, Jig. 151, — originally regarded as a native of the New World, and 

 named accordingly, but since ascertained to be African.
