The South London Entomological and Natural History Sociuty : 

 Thursday, .Jul;/ 9t/i, 1908.— .Mr. Alfred Sich, F.E.S., President, in the Chair. 



Mr. Ily. J. Turner exhibited a female specimen of Agriades bellargus caught 

 at Ranmore, measuring only 22 mm. in expanse, and an example of Hesperia malvas 

 from Eastbourne with hind-wings normal, but having coalesced blotches on the 

 fore-wings as in ab. tarax. Mr. Newman, living larva; of Xi/lina semibrunnea with 

 that of X. soda for comparison, pointing out the peculiar green ground tint and the 

 more distinct lateral line of the former. Mr. Adkin, light and dark forms of larva; of 

 Biston hirtaria, pointing out that the difference was permanent through each moult, 

 and that the depth of colour did not seem to depend upon environment. Mr. West 

 (Greenwich) the following Hemiptera taken by him in Juno in the New Forest : — 

 Cicadetta montana, Sigara minutissima, Eysarcoris aineus, and Orthostira cervina. 

 Air. Oarr, the nymph skin of the large Dragonfly Anax imperator, found at Oxshott. 

 Air. Sich, a larva and pupa of Parnassius apollo ? sent by Air. Egbert Sich from 

 the Engadine, Switzerland, and stated that when irritated the larva protruded an 

 osmaterium. Mr. Tutt called attention to the waxy secretion covering the surface 

 of the pupa which effectually secured it from the damp of the marshy ground upon 

 which it pupated. — Hy. J. Turner, Hon. Secretary.
