Schaum (C. punctata, Schonh nec Donov.), and Sell. Thoreyi 
Schaum (n. sp.), into a small group distinguished by their tropical 
African habitat, and the elongated form of their bodies; the tibiae of 
the males being bidentate, and those' of the females tridentate. 
There is, however, considerable difference between the form of the 
clypeus, mesosternum, and fore tibiae of the males of Iris and 
cyanea; the apex of the suture of the elytra in the latter species is 
also bispinose, whilst it is rounded off in the former. 
Tmesorrhina simillima (pi. 19, fig. 4, p. 72).—In addition to 
the structural differences noticed in the description and figure above 
referred to, it should be added that the mesosternum instead of 
terminating in a short rounded process (as in Tm. Iris and concolor, 
pi. 19, fig. 3 e), is long, acute, and slightly bent upwards at the tip. 
It must be left for a more detailed revision of the entire group to 
determine whether this character (which has just been stated to 
differ also in Sch. cyanea) will render it necessary to remove Tm. 
simillima from the other two species.

In a former page I have dwelt upon and lamented the wide distinc¬ 
tion which exists between our own and Continental nations in regard 
O 
to the patronage offered by their respective governments to works of 
natural history. The little work at the head of this article offers 
another equally striking proof of the advantages enjoyed by Continental 
naturalists far exceeding those which English students possess. Na¬ 
tural history being one of the branches of education taught in all the 
German burgher schools, gymnasiums, and universities—there being 
a professor of zoology in each of the latt er—it follows that whenever a 
student manifests a decided predilection for any particular branch of 
the subject, his professor encourages him in it, and under his good 
directions the tyro launches forth his “ dissertatio inauguralis,”—in a 
style as far superior to the feeble efforts of English debutants as can 
well be conceived. The inaugural dissertation of Goldfuss on the 
Coleoptera of the Cape of Good Hope, that of Burmeister “ De 
insectorum systemate naturali,” that by Erichson on the Dyticidm, 
that of Schmidt on the Pselaphidm, that of Itunde on the Brach- 
elytra, and Dr. Schaum’s dissertation, amply confirm the truth of 
these remarks ; all of them being works of talent, which will cause 
them to be always cited, and which, it is needless to suggest, have
