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, Euplcca, and 

 ^patura, of which nine are regarded as new to science. The far 

 greater number belong to Papilio and Euplcca, 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 

 pubhcation of his " Ausser-Europaische 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 antennw. For the accuracy of the descriptions the 

 well-known character of the authour is a sufficient guarantee.
