Exhibitions, dc. 



Mr. E. B. Poulton exhibited a mass of minute crystals of 

 formate of lead, caused by the action of the secretion of the 

 larva of Dicranura vinula upon suboxide of lead. He stated 

 that a single drop of the secretion had produced the crystals 

 which were exhibited, and he called attention to the excessively 

 high percentage of formic acid which must be present in the 

 secretion, and to the pain and probable danger which would result 

 from being struck in the eye by the fluid which the larva had the 

 power of ejecting to a considerable distance. A discussion ensued, 

 in which Messrs. White, Kirby, Slater, and otliers took part. 



Mr. S. Stevens exhibited a specimen of Laphtjgma exlgua, 

 recently captured by Mr. Ptogers, in the Isle of Wight. 



Mr. W. F. Kirby exhibited a specimen of Perilampus viaurus, 

 Walk., recently bred by Mr. Walter de Rothschild from Anthercca 

 tirrhcd, Cram., one of the rarer South African Saturnidcc. Mr. 

 Kirby stated that the species of Perilampus do not seem to be 

 particular about their food ; Dalman supposed his P. micans to 

 be parasitic on Hister jricipes ; and Westwood observed P. 

 angustus on posts perforated by Anobia. Snellen Van Vollen- 

 lioven mentions that Lichtenstein bred P. auratus, Pauz. from 

 the cocoon of a species of Crabro; and that Reissig obtained 

 P. riolacciis, Fab., from a cocoon found dangling by a thread 

 from the remains of the caterpillar of a Tortrix. G. Thomson 

 says briefly that Dalman supposed Perilampus to be parasitic on 

 Coleo})tera, but that it is really parasitic on Lepidoptera. 



Mr. T. W. Hall exhibited a number of specimens of Xanthia 

 fulvago [cerago), somewhat remarkable in their variation, and 

 showing a graduated series, extending from the pale variety 

 flavescens of Esp. to a form almost melunic in its markings. Mr.
