There was also read, " Descriptions of some new Insects collected 

 in Assam, by William Griffith, Esq., Assistant Surgeon in the Madras 

 Medical Establishment." By the Rev. F. W. Hope, M.A., F.R.S., 

 and L.S. 



This paper contains a further selection of new insects from Mr. 

 Griffith's Assam collection in the possession of Mr. Solly, an account 

 of part of which has been already noticed at p. 42, and has since 

 appeared in the Society's Transactions. The descriptions are ac- 

 companied by coloured figures. The species described belong chiefly 

 to the group of Luca?iidce, and are as follows : —
