20 DESCRIPTION OF NEW COLEOPTERA, 



of all the known species of the subgenus Schizorhina may be 

 acceptable to some of our Entomologists. 



In order, however, to make it satisfactory to myself and in- 

 telligible to others, I must, as succinctly as I can, explain the 

 position and divisions of the group we have been considering. 



Mr. MacLeay, in the 3rd No. of " Smith's Illustrated Zool. 

 of South Africa," in an admirable review of the whole 

 family of Cetonitda', divides them into five genera, viz., Trichinus, 

 Gryptodinus, Macrominus, Gymnethnis, and Getonmus. It is with 

 the last of these only, the typical and most numerous genus, 

 that we have now to do. 



Cetoninus is divided by Mr. MacLeay into the subgenera 

 Schizorhina, Conjphe, Goliathus, Ischnostoma, and Cetonia. It is 

 the first and last of these sub-genera only, in which any 

 Australian insects ai-e to be found. The first is entirely 

 Australian, while Getonia contains of Australians, only the 

 group which I have named Lenosoma, and a species G. brun- 

 nipes, which is apparently of the same section as the European 

 G. stictica. The subgenus Getonia is evidently by means of 

 Lenosoma connected with Schizorhina, which subgenus Mr. 

 MacLeay further sub-divides into five sections, viz., Brwionice, 

 Fhlllipsice, Integrce, Gymnopleurce, and In-tulares. 



Burmeister, subsequently in his " Handh. d. Entom. IIV 

 adopted the charactei'S Mr. MacLeay had given to these sections, 

 but gave them names of his own, and called them genera. 



These sections are susceptible of further sub-division. Indeed 

 Mr. MacLeay has divided into sub-sections some of the more 

 numerous sections of Getonia. In Schizorhina, however, 

 the number of species in each section is not so great as to render 

 further sub-division necessary. Still any one acquainted with the 

 subgenus must have noticed the natural grouping of the species, 

 and the ease with which further sub-division might be made ; for 

 instance, the section " Integree " at once resolves itself into at 

 least three groups, which I have marked in the next page, the 

 first consisting of four species, remarkable for the rounded yellow 

 apex to the mesosternum ; the second, of those which resemble 

 dorsalis in form and colour ; and the third, the group of which 

 frontalis is the type, and of which there are, I believe, some un- 

 flescribed species in the collection of Mr. MacLeay.
