tained full grown, by beating the trees it affects, in its localities, about 

 midsummer. Several larvae of the Geometnna however fold leaves 

 when young, as the pale green caterpillars of the Tissue ( Cotosia 

 dubitata ) on buckthorn, and others of the genus, the bluish-grey vetulata 

 and variable dark-brown or green rhamnata, also fold buckthorn leaves 

 in May. The local cevtata folds barberry leaves at the beginning of 

 June, and the young larvae of undulata those of sallow in the autumn. 



Among the pyralites we have several leaf-uniting larvae. Some of 

 these, as the greenish-grey yellow-striped Pyrausta punicealis on mar- 

 joram and the dark-grey Purpuralis, also with yellowish-dorsal and 

 spiracular lines on mint, live inside a slight web between the leaves of 

 low plants; the well-known green Botys rumlis and dull whitish 

 urticalis are familiar to everyone as fastening together the leaves of 

 stinging nettles, and others of the family roll or unite leaves; thus, we 

 find the dull green larvae of Ebulea crocealis on woad in the spring, and 

 the pale-green sambucalis on elder and convolulus in the autumn, the 

 yellowish-green S copula lutealis on Coltsfoot in May, the transparent 

 blackish-green olivalis, and the pale green prima! is, both of which feed 

 on various low plants in the spring.

The Secretary read a letter from the Vicar of Arundel, asking for advice as to the 

 course to be taken to get rid of the larvae of a beetle which were destroying the beams 

 of the Parish Church. Mr. C. O. Waterhouse said he had already been consulted on 

 the question, and had advised that the beams should be soaked with Paraffin oil. 

 Dr. Sharp, Mr. M'Lachlan, Dr. P. B. Mason, and the Chairman made some remarks 

 on the subject. 



Dr. Sharp exhibited specimens of Caryoborus lacerda, a species of Bruchida, and the 

 nuts from which they had been reared. He stated that three of these nuts had been 

 sent him from Bahia by the late Senor Lacerda, about six years ago ; that one of the
