48 ARCANA ENTOMOLOGICA. 
Bombycidz, by Mr. Doubleday, with an outline plate engraved by 
W. Raddon, Esq., from original drawings by Abbot, and-a memoir on 
the Aulacidse, and some allied Hymenoptera by Mr. Shuckard, are 
also introduced. Abstracts are also given of the Volume of Insects 
in the Cabinet Cyclopedia ; the transactions of the Entomological 
Society, the Annals of Natural History, the Canadian Naturalist, 
and of the first number of this work. A number of short commu- 
nications of minor importance are also introduced, as well as a few 
woodeuts; and in each of the two last numbers is given an out- 
line plate of various genera of Chalcidide, described in the 
Entomological Magazine. 
Investigation or tHE Myrtaropa.—This long-neglected but 
highly curious group of Annulose animals has recently received 
much attention by Dr. Brandt of Petersburgh, and M. Gervais of 
Paris. In our own country, Mr. G. Newport has also undertaken 
their investigation, and it is with great pleasure that I mention 
that a paper by him upon the development and growth of the large 
English Iulus has been selected by the Royal Society for the 
Bakerian lecture of the present year; and that an elaborate 
memoir by him on the entire group, with copious illustrations, may 
shortly be expected.
