fections of the Fabrician arrangement as compared with the present state 
of entomological science, but refrains from making any alterations, his 
object being merely, as he states, to describe a certain number of insects 
as natives of a particular country. To this object his paper is strictly 
limited: he describes thirty-two species belonging to the genera 
Amathusia, Papilio, Zelima, Morpho, Cethosia, Euplea, and 
Apatura, of which nine are regarded as new to science. The far 
greater number belong to Papilio and Euplea, fourteen being referred 
to the former genus, and nine to the latter. Three plates are filled with 
good figures of the new species, and of some of those which had been 
previously described. Among them we find one to two apparently 
identical with species figured, but not yet described, in Dr. Horsfield’s 
© Lepidoptera Javanica.” 
The second systematic paper in this department of zoology is a 
‘¢ Monographia generis Midarum, a C, R. G. Wiedemann,”’ and offers 
a very full and complete illustration of a genus of dipterous insects not 
more remarkable for the peculiarities of its structure than for the rapidity 
with which its numbers have been swelled by recent accessions. In the 
year 1820, the learned authour described, in Meigen’s excellent work 
on European Diptera, a second species in addition to the solitary indi- 
vidual left by Latreille under the Fabrician denomination. In the 
following year he added, in the first part of his “* Diptera Exotica’’ five 
other species; and their number was increased to twelve, on the 
publication of his ‘* Ausser-Europiische Zweifliigelige Insekten,” in 
1828. The present Monograph contains characters, descriptions, and 
figures of no fewer than twenty-three, and is preceded by a critical 
dissertation on the origin and orthography of the generic name; on the 
history of the genus, with a critical examination of the characters assigned 
to it by successive systematists; and on the habits attributed to its 
species by Olivier, but neglected by subsequent writers. The figures, 
which occupy three plates, are well executed, and are accompanied, as 
regards some of the smaller species, with enlarged representations of 
the wings, legs, and antenne. For the accuracy of the descriptions the 
well-known character of the authour is a sufficient guarantee.
