Exhibitions, Memoirs, &c. 



Mr. Westwood exhibited a specimen of Claviger foveolatus, 

 captured by himself in the nest of Formica fiava in Wychwode 

 Forest, Oxfordshire, at the end of the preceding month. 



He also exliibited specimens of Calandra granaria, two species 

 of Lalrid'tus, a Silvanus, and Cryptophagus, together with Tinea 

 granella, all of which attack barley in granaries ; and made some 

 observations on the larva of Cal. granaria, which differs from Cal. 

 Sommeri, Burra., in having the extremity of the body entire and 

 fleshy. 



He also exhibited various nests of bees and wasps in diflferent 

 states of progress. 



Mr. Waterhouse made some observations on the mode adopted 

 by bees in the construction of the cells, in opposition to the theory 

 of some authors, that the cells are hexagonal in consequence of 

 the pressure of cylinders against each other ; whereas Mr. Water- 

 house considered that the bees naturally work in circles ; but as 

 the cells approached each other, the bees were compelled to form 

 the sides of the cells straight. This was sometimes very clearly 

 shown in the cells at the edge of a comb, the inner sides of which 

 would be angular, but i\\e free sides round. 



Mr. Bovverbank noticed a similar power of adaptation in the 

 shell of an Ostrcea plana, attached to a Mytilus. 



Mr. Westwood read a memoir on the modifications of form to 

 which the typical organs of the Diptera are subject.
