Schaum (C. punctata, Schonh nee Donoy.), and Sch. Thoreyi 
Schaum (n. sp.), into a small group distinguished by their tropical 
African habitat, and the elongated form of their bodies ; the tibize 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 tibize 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. 
Tmesorruina simitiima (pl. 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, 
pl. 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 distine- 
tion which exists between our own and Continental nations in regard 
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 proofoftheadvantagesenjoyed by Continental 
naturalists far exceeding those which English students possess. Na- 
tural history being one of the branches of education taught in all the 
Germanburgher schools, gymnasiums, and universities—there being 
a professor of zoology ineach of the latter—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 mauguralis,”—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 
isectorum systemate naturali,” that by Erichson on the Dyticide, 
that of Schmidt on the Pselaphide, that of Runde on the Brach- 
clytra, and Dr. Schaum’s dissertation, amply confirm the truth of 
these remarks ; allof them being works of talent, which will cause 
them to be always cited, and which, it is needless to suggest, have
