of Ichneumonidae, but I have to add eight species of Diptera 

 to the present list : the first being Trixa vatiegata, Meig., one 

 female of which Mr. South bred from Cheimatobia boreata, Hb. 

 NemorcEa notabilis, Mg., was bred from the larva of Plusia 

 festuccE, L., by Mr. Adkin, one male and two females ; while 

 three females of the very rare Nemorcea nigrithorax, Mg., 

 were bred by Mr. Fenn from the larva of Saturnia pavonia, 

 L. ; both sexes of the very handsome Masicera sylvatica, 

 Mg., were bred by Messrs. Fenn and Winkley, one from 

 Saturnia pavonia, L., and the other from Picris brassiccB, L. 

 Three specimens, a male and two females oi Plagia curvinervis, 

 Fin., were bred from the larva of Pcedisca sordidana, L., by 

 Mr. Adkin ; while from the same host he bred a single female 

 of Hypostena medorina, Schin. Phorocera concmnata, Mg., 

 was bred in some numbers from Vanessa nrticcE, L., both by 

 Messrs. Frohawk and Winkley. Tachina tibialis, Mg., was 

 bred by Mr. Frohawk from Vanessa urticce, L., both sexes 

 being represented ; and from larvae of the celery fly, Acidia 

 heraclei, L., I have bred both sexes of the very beautiful 

 Chalcid, Phargonia smaragdula. 



It only remains for me to thank very heartily the members 

 of the Society who have so very kindly responded to my in- 

 vitation to save the parasites that they may breed from time 

 to time, and thus enabled me to so largely add to my previous 

 list. I can only hope that others may be induced to follow 

 in the future the very admirable example set by the gentlemen 

 I have named, and thus enable me to produce a much more 

 formidable list on some future occasion. 



Notes upon Terrestrial Mollusca found near Toulon. 



By John T. Carrington, Esq. Read April 2-^rd, 1891. 



During my stay in the Riviera in the South of France, 

 extending from November imtil February of the past winter, 

 1890-91, I occupied some of my time by collecting the 

 land snails of the district surrounding the city of Toulon. 

 My head-quarters were on the shores of the Mediterranean, 

 some little distance from the city, and near the picturesque 

 Cap Brun. This portion of the Riviera is not one that 

 would be chosen by a naturalist who went in the summer 

 time, because, like other districts of Southern Europe, where 

 the soil will yield four crops in a year to the industrious
