 Note. Tbis species varies in the number of white spots on the elytra, but may always be known by 

 three that are placed in a transverse oblique line on each elytron, and by the two large triangular white 

 spots on the anal plate. 



Sp. 57. (Cetoninus) Cetonia nympha, n. s. 



Descb. Cetonia viridis, nitida, capite quadrate vix emarginato, vertice ad oculos albo-bimaculato, 

 prothoracis punctati margine laterali, elytrorum vix striato-punctatorum macula humerali 

 longitudinali, aliis quinque marginalibus duabusque discalibus albis, elytris apice triangulari 

 depresso, scapulis macula albi, ano maculis duabus emarginatis albis, corpore subtiis piloso, 

 prothorace mesothorace et metathorace subtus albo-bimaculatis, mesostemo viridi, abdominis 

 segmento ultimo bmiaculato tribusque penultimis quadrimaculatis maculis albis, pedibus 

 viridibus. 



Long. 10^ lines.

 Note. We thus return to Cetonia pubescens, and those other species having the elytra, or at least the 

 body covered with hair, and which form that section of the sub-genus Cetonia which I have termed 

 Trichioidew. Thus, therefore, the circle composed of the five sections of Cetonia is complete. 



94. We have now gone through a complete revision of all the sub-genera composing the 

 family of Cetoniidce, and which are as follow ; the sub-genera, in italics, being those by which 

 the passage is made from one genus to the other. 



1 Trichinus. 2 Cetoninus. 3 Gymnetinus. 4 Macrominus. 5 Cryptodinus. 



1 Osmoderma. 1 Schizorhina. 1 Lomaptera. 1 Oplostomus. 1 Genuchus. 



2 Valgus. 2 Coryphe. 2 Agestrata. 2 AnoplocheUus. 2 CycUdius. 



3 Trichius. 3 Goliathus. 3 PMlistina. 3 Diplognatha. 3 Cremastocheilus. 



4 CampuUpus. 4 Tschnostoma. 4 Macronota. 4 Gnathocera. 4 Cryptodus. 



5 Platygenia. 5 Cetonia. 5 Gymnetis. 5 Macroma. 5 Cymophorus. 



Were nature to set before our eyes eveiy one of these groupes in a state as complete, for instance, 

 as is that section of Cetonia which I have called TypiccB, we should, of course, have of the 

 Cetoniidce 125 sections and 625 sub-sections, &c. &c. But this is not the case ; since, from 

 some unexplained cause, each groupe of the same rank contains a different number of species, 

 and thus throughout the creation we see certain parts of the chain comparatively complete in all 

 their links, and others again offering nothing but objects which appear to the superficial 

 observer at first sight to be insulated, and, in fact, require deep study on the part of the 

 naturalist before he is enabled to make out their accurate affinities. It is needless to repeat 

 that I, as well as others before me, have imagined the cause of this insulation of particular 

 objects to arise from the connecting species having been either lost or undiscovered. 



95. The conclusion to which we tend by such an analysis as the foregoing, is, that the lowest
