Note. This 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 nymplia, n. s. 
Descr. Cetonia viridis, nitida, capite quadrato vix emarginato, vertice ad oculos albo-bimaculato, 
prothoracis punctati margine laterali, elytrorum vix striato-punctatorum macula humerali 
longitudiuali, aliis quinque marginalibus duabusque discalibus albis, elytris apice triangulan 
depresso, scapulis macula alba, ano maculis duabus emarginatis albis, corpore subtus piloso, 
prothorace mesothorace et metathorace subtus albo-bimaculatis, mesostenio viridi, abdominis 
segmento ultimo bimaculato tribusque penultimis quadrimaculatis maculis albis, pedibus 
viridibus.

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 
Trichioidece. 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 Genuchm. 
2 Valgus. 
2 Coryplie. 
2 Agestrata. 
2 Anoplocheilus. 
2 Cyclidius. 
3 Trichina* 
3 Goliathus . 
3 PJiilistina. 
3 Diplognatha. 
3 Cremastocheilns. 
4 Campulipus. 
4 Ischnostoma. 
4 Macronota. 
4 Gnathocera. 
4 Cryptodus. 
5 Platygenia. 
5 Cetonia. 
5 Gymnetis. 
5 Macroma. 
5 Cymophorus. 
Were nature to set before our eyes every one of these groupes in a state as complete, for instance, 
as is that section of Cetonia which I have called Typicce, 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
