his biological studies. Dr. G. H. Horn has just published the 
Termitophile Larva of Glyptus sculptilis, from the Museum col- 
lection of Mr. F. Blanchard, Lowell, Mass.; Lieutenant Casey, 
Newport, R. L, and S$. Henshaw, have studied the Le Conte 
collection; Mr. L. Cabot has finished his memoir on the early 
stages of the Cordulina, and it is in the hands of the lithogra- 
pher. The Assistant has arranged some parts of the collec- 
tion, and incorporated some of the later additions. A number 
of students have, as usual, studied the type collections in the 
Museum. 
The large monograph ,of the Ephemeride, by Rev. A. E. 
Eaton, is finished, and fills the whole of the third volume of the 
Transactions of the Linnean Society, London, pp. 352, pl. 65. 
There are not many pages where the Museum collection has not 
given help, and many figures on the plates are made of material 
communicated by the Museum. Dr. G. Czwalina has from 
material from the Museum published in the Deutsche Entomol. 
Zeitschr., 1888, Vol. XXXII. pp. 338-854, pl. 2, «Die Forcipes 
der Staphyliniden Gattung Lathrobium” (only just arrived). 
Mr. Beutenmiller has published in the Entomologica Americana, 
1888, from Museum material, ‘‘ New Species of North American 
Tineide,’ nearly a monograph of the genus Aorolophus. 
In consequence of the large additions, some parts need an 
entirely new arrangement ;— the North American Lepidoptera, 
the Ephemeride, the Termitide, and the early stages of the 
Odonata. :

past academic year : —
