Exhibitions, Memoirs, &c. 



Mr. Westwood exhibited various insects from the Collection of 

 the Rev. F. W. Hope, presenting several remarkable physiological 

 peculiarities, namely : 



A specimen of Curculio Reid'/i, K. (see Plate VL fig. 3), from 

 between the head and front of the prothorax of which a Dipterous 

 larva had protruded itself, and there died without being able to 

 extricate itself or assume the pupa state ; two other smaller dead 

 Dipterous larvae had also been found within the prothoracic cavity 

 on removing it from the body. 



A specimen of a large species of Acanthocephalas (family 

 Coreidce), from the scutellum of which a great number of filamen- 

 tous fungi had been produced, each being as long as the entire 

 body, (see Plate VL fig. 7, and 7 a, part of one of the filaments 

 magnified). 



Two specimens of Euglossa (family A-p'idce), from the basal 

 portion of the abdomen of each of which an elongated process had 

 been produced, which was bent backwards and rested on the dor- 

 sum of the abdomen ; in one of the specimens the appendage was 

 divided at the extremity into two branches (see Plate VL fig. 1, 

 1 a, the appendage seen from above ; 1 h, ditto seen sideways) ; 

 and in the other it was dilated into two reniform lobes (see Plate 

 VL fig. 2, 2a, the appendage seen from above; 2h, ditto seen 

 sideways). Mr. Westwood considered it most probable that 

 these were vegetable substances in different states of development. 



Mr. Evans presented a drawing of the New Zealand caterpil- 

 lar attacked by Sphaeria Rohertsii (Hooker, Icones Plantar. L 

 pi. 1 1), of which he also exhibited a specimen (see Plate VL fig. 

 4*), Mr, Westwood stated that he had examined the internal 

 appearance of one of these caterpillars, communicated to him by 



* Plate VI. fig. 5, represents the Chinese caterpillar similarly infested by 

 Clavaria Enlomorhiza, described in the Journal of the Proceedings of the Society 

 for the 1st March, 1841.
