In this essay the authors propose to themselves to bring the 
natural history of the genus Mutilla down to the present time, 
so far as relates to the species of the Old World. They reject 
the generic divisions formed by Wesmael, Costa, and Morawitz, 
on the ground of insufficiency, and revert to the older system 
of Latreille. Only a small portion of the monograph is' in the 
hands of the Recorder, and it is probably all at present pub- 
lished. The work appears to be excellently conceived and car- 
ried out, so far. It commences with a general history of the 
subject, of an exhaustive character, followed by analytical tables 
for the determination of 145 species. .The first eight species 
are also described, one being new.

This list contains the first four families of the Hymenoptera 
of Holland, under the somewhat cumbrous names Tenthredi- 
nidea, Siricidea, Ci/nipidea, and Evaniadea. The total number 
of species is 299, of which 220 are Tenthredinidce, Each name 
is accompanied by references to the best descriptions, and notes 
of locality. The paper concludes with remarks on many of the 
species, and some descriptions of new forms, which will be 
noticed in their proper places.
