workmanship. Before the escape of the imago there was no 

 trace of any convenient exit, and it was only by pressing the 

 hard seed capsule between the finger and thumb that the 

 existence of a perforation could be delected. Pressure caused 

 the skin of the seed over the boring to become depressed, and 

 so the situation of the hole was discovered. 



Mr. J. R. Wellman exhibited Dianthcecia albimacida, 

 Bork., forms of Bryophila mtiralis, Forst., and a yellow variety 

 of B. perla, Fb., all from Folkestone ; Plusia interrogationis, 

 L., from Perth ; also dwarfed forms of Aspilates gilvaria, Fb., 

 Eubolia bipunctaria, Schiff., and E. limitata, Scop., which he 

 stated were all captured on the slopes of the hills near the 

 Canterbury Road. It was remarkable that there should be so 

 many undersized examples. 



Mr. R. South observed that these small specimens were 

 very interesting, and were no doubt to be attributed to the 

 parched and stunted condition of the larval food-plants, 

 owing to the unusually dry summer. 



Mr. Barker, on behalf of Mr. G. A. Lewcock, exhibited 

 a lar^e series of Coleoptera, including a specimen of Seri- 

 cosomos brunneiiS) L., from Esher ; a long series of Bembidium 

 lunatum> Duft. Mr. Lewcock has occasionally taken the 

 latter singly on the banks of the Thames at Rainham, Essex ; 

 but during last season he captured about a dozen specimens 

 one afternoon in August. The following species of Donacia 

 were also shown (all taken during the year), and the accom- 

 panying notes read : — 



Donacia versicolor^ Brahm., and D. dentata, Hoppe, from 

 the Basingstoke Canal and Farnham, obtained chiefly on the 

 floating leaves of several water-plants. The best means of 

 capturing these species is to submerge the resting-place, 

 when, being deprived of the means of flight, the insects could 

 be easily taken. D. hydrochceridis, F., from the stems of 

 rushes, Basingstoke Canal ; the best time to take it being 

 early in the morning. D. bicolora, Tsch., Basingstoke Canal 

 and Farnham, frequenting the yellow Iris ; also to be swept 

 at times from the low rushes. D. thalassina, Germ., Basing- 

 stoke Canal, Esher, Farnham, and Sunbury; generally common
