212 FOURTH REPORT — 1834. 



L^conte, in the latter by Rambur and Graslin. Dr. Horsfield 

 has thrown much Ught upon the arrangement and affinities of 

 these insects in his Lepidoptera Javanica, already alluded to in 

 a former part of this Report. 



The Neuroptera have been particularly attended to by Tous- 

 saint Charpentier and Vander Linden, who have each published 

 a inonograph on the European LiheUulcE : that of the former 

 is contained in his Horce JEntomologiae. The Phryganece 

 {Trichoptera, Kirb.) form the subject of an elaborate and valu- 

 able work recently published by M. Pictet of Geneva*. 



The only recent works devoted to the Hymenoptera, with 

 which I am acquainted, are those of Lepelletier de St. Fargeau, 

 Gravenhorst, and Nees ab Esenbeck. The first has published a 

 monograph on the Tenthredinida;f. The second has treated at 

 great length of the European species of IchneumonidcBX- The 

 third has written upon the more aberrant groups of the family 

 just mentioned§. 



The Diptera have received great attention of late years from 

 several excellent entomologists. Fallen's Diptera Suecice is 

 rather anterior to the period of time we are considering. Wiede- 

 mann's Diptera Exotica ||, Meigen's Diptera of Europe^, and 

 Macquart's Diptera of the North of France**, are of more re- 

 cent date, and have greatly contributed, the last two especiallj^, 

 to advance our knowledge of this order of insects. I may also 

 allude to a most elaborate work by Robineau-Desvoidy, which 

 though treating only of the Fabrician genus Miisca, contains 

 descriptions of nearly 1800 species, referred to nearly 600 

 genera. This astonishing production, which is entitled JEssai 

 sur les Myodaires, occupies the entire second volume of the 

 Mem. des Savans E'trang., published in 1830. 



Besides the above works, I may mention Stephens's Illustra- 

 tions of British Entomology, now in course of publication in 

 our own country, as one which promises great additions to all 

 the orders. The Coleoptera and Lepidoptera have already 

 appeared. Curtis's British Entomology is confined to the il- 

 lustration of the genera of British Insects, but as a work in the
