156 . Mr. Kirby on some new genera and species 



glabra, subpruinosa, lutea : maculis novem Digris, nempe 1 hume- 

 rali magno, 2, 3, 2 transverse ordinatis, intermediis duabus later- 

 alibus irregularibus confluentibus minoribus, et 1 apicali reliquis 

 majori. Maculae tres farinoso-fulvae ; intermedio oblongo, late- 

 ralibus obliquis sinuatis, podicem signant. 



I may perhaps render some little service to the Entomologist, 

 if, as a conclusion to this paper, I endeavour to point out the 

 natural groups into which the true genus Trichius, according to 

 my idea of it, and as far as my own collection will enable me, may 

 be resolved. 



Fabricius, in his Systema Entomologice and Species Insectorum^ 

 took for the type of his new genus Trichius^ which he so named, 

 I suppose, on account of its hairy body, Scarabceus fasdatus of 

 Linne : but in his later works he seems to have considered T. 

 Eremita as his type, which beipg nearly a naked insect, does not 

 so well correspond with the name. I shall consider the former a^ 

 the true type of the genus, which as far as my own collection 

 leads, I find to consist of seven subgenera as follows : 



Genus. Trichius F. 

 Subgenera. 



* Legitimi. Hirsuti : elytris nudis pruinosis ; cubito bidentato • 

 podice farinoso-maculato ; palpis articulo extimo subin- 

 crassato supra foveato. Ex. Trichius fasciatus^ succinctus, 

 Bigsbiiy &c. 



** Trichini. Hirsuti; elytris nitidis; lineolis maculisve farinosis; 

 podice farinoso-maculato ; Palpis articulo extimo tenui- 

 ori supra foveato, Ex. Trichius viridulus^ pig^^y and 

 some others from North America. 



*** Tetrophthalmi. Hirsuti : elytris nitidis, immaculatis ; cantho 

 oculuui fere dividente ; cubito tridentato ; calcaribus 

 tibiarum posticarum elongatis obtusis ; podice immacu- 

 lato ; palpis articulo extimo foveato. Ex. Trichius sutu-' 

 laris K.M.S. An undescribed species from Java. 



**** Archimedii, Subtus dense squamulosi, supra pruinosi : 

 podice item squamuloso ; prothorace triangulo aequilate-
