of our Neuroptera, Osmijhis rhri/sops. The exhibit was made on account 

 of the larva having been taken by Dr. D. Sharp near Queen's Bower in 

 the New Forest. It pierces and sucks dry some small animals, but its 

 life-history is not well known. The mouth-parts are similar to those 

 of Heuierobius and Chnjsopa, which feed on the juices of aphides. O. 

 chrysops is, however, at least partly aquatic. It is nearly related to 

 Sisyra, of which we have three species, one at least of which feeds on 

 Spomiilla finviatilis. Colour variation of Aglais pup^. — Mr. A. 

 W. Bacot showed two boxes containing pupal cases of Ar/lais urticae 

 collected by Mr. Hugh Main in one locality. Those taken from the 

 foodpiant were yellowish-white ; those taken from the cage in which 

 the larvfe pupated quite blick, thus demonstrating the effect of 

 surroundings upon the pupal coloration. 



The South London Entomological and Natural History Society. 

 ■ — -Uctober 2Sth, 1909. — Larv.e of Pharetra rumicis. — Mr. Tonga

 sallow. Variation in Hylophila prasinana. — Mr, South, a series of

 finding of Noctna xant/iof/rapJia ^ , and Luperina testacea ? , in cop.,

 number of similar strange unions noted in A Natural History of the 

 British Lepidoptera, vol. v., pp. 2-3. Depressaria putridella. — 

 Mr. Sich, for Mr. Green, this new British species recently recorded, 

 and its life-history described in detail, in the Ent. Record for October,

 and the light area at the base of the abdomen. Aberrations op 

 Agriades thetis and A. coridon. — Dr. Hodgson, specimens of 

 Agriades coridon with white submarginal wedges and partial absence 

 of spots on the underside of the hindwings, and also examples of A. 

 thetis (bellargits) without discoidals. Attempted autumn brood of 

 Pyrameis atalanta. — Mr. Newsman, nearly full-fed larvae of Pyrameis 

 atalanta from ova laid in August. 



Lancashire and Cheshire Entomological Society. — October ISth,
