156 Mr. Kiiby on some nexa' genera and species 



glabra, subpruinosa, lutea : macuHs novem nigr'is, nempe 1 hume- 

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

 alibus irregularibus confluentibus mlnoribus, et 1 apicali reliquis 

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

 ralibus obliquis siiiuatis, 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 Sysicma Entomologice and Species Insect or iim^ 

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

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

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

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

 so well correspond with the name. I shall consider the former as 

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

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

 jenera. 



* LegUimi. Hirsuti : elytris nudis pruinosis ; cubito bidenlato ; 

 podice farinoso-maculato ; palpis articulo cxtimo subin- 

 crassato supra foveato. Ex. TrichiusfasciatuSy succincius, 

 Bigsbii, Sec. 



** Trichini. Kirsuti: elytris nitidis; lineolis maculisve farinosis; 

 podice farinoso-maculato; Palpis articulo extimo tenui- 

 ori supra foveato. Ex. Trichius viriduluSy piger, and 

 some others from North America. 



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

 oculum 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 aiquilate-
