the entomologist who undertakes to examine them. The 

 Museum will pay all expenses connected with the packing and 

 carriage of the specimens, and, when possible, will send 

 duplicates, in addition to the set required to be returned for 

 exhibition in the Museum. 



It is hoped that amongst the entomologists of your Society 

 who make a study of special groups of insects, there may be 

 found some who are willing and able to avail themselves of 

 the present opportunity of assisting in a work which cannot 

 but tend most materially to the advancement of the study of 

 the little -known Entomology of India. 



The following are the chief groups not yet undertaken, and 

 for which, therefore, assistance is desired : — Neuroptera. — 

 Myrmeleonida;, Panorpiihv, Ascalaphidm, Maritisjnda, Heviero- 

 biidcB, SialidcB, TrichopteridcB, Termitidcs. Pseudo-Neuroptera. — 

 PerlidcE. Diptera. — Nemocera. Coleoptera. — CaraUdcB 

 (except genera Carahus and Calosoma], Hydro phi lido;, Faussid<s, 

 Dermestida, Lucanidce, Coprini, Rutelini, Dijnastini, Cetonini, 

 MonommidcE, LngriidiB, Melandnjidai, Clerida, Rhiphidocenda;, 

 AniIiicid(E, BmchidcB, AnthotribidcB, SagmicE, Cryptoceplialina, 

 Halticinm, GalerucincB, Languriida;. 



Any communication addressed to me on the subject of the 

 determination of the above groups of insects will receive 

 prompt attention.
