Mr. Herbert Williams exhibited a long series of Pieris 

 napi, L., the progeny of two females of the 1893 spring 

 brood. In one case ova were deposited by a female taken in 

 Northamptonshire, on May 2nd, larv^ hatched on the lOth 

 of that month, fed up rapidly, and commenced to pupate on 

 June 1st, and all were in the chrysalis state by June 7th. 

 None of the butterflies emerged until the spring of 1894. In 

 the second case a female captured at Edgware, Middlesex, 

 deposited ova on May 8th, 1893, the larvae hatched on May 

 13th, and commenced to pupate on June lOth. One butter- 

 fly, a female, and almost intermediate in form between the 

 spring and summer broods, emerged on June 24th, but all 

 the others remained in the chrysalis until the spring of 1894. 

 Mr. Williams was of opinion that this species requires mois- 

 ture as well as heat to induce it to leave the pupa. 



Mr. Sauze exhibited species of various orders obtained on 

 the occasion of the Society's Field Meeting at Seal Chart, 

 including Coleoptera: Cceliodes qiiadrimaciilatus, PJiyllobius 

 giaiicus, P. argentahis, Coccinella 1%-giittata, C. decempitnc- 

 tata, Telephorus pailtdus, T. hcemo}rhoidal{s, Dolophis mar- 

 ginatus, Erirrhinus tortrix, Strophosoniits coryli, RhyncJiites 

 betuloi, Lupcriis flavipes. Diptera : Dryoniyza flavcola, Spilo- 

 grapJia zoe. 



Mr. Turner exhibited two specimens of the rare Homop- 

 teron, Centrotus cornutus, L., taken at Seal Chart by Mr. 

 Lewcock, and read the following note : — 



" Centrotus cormitus is one of the few, I believe only two, 

 British species of that remarkable family MembracidcB. This 

 family is well known for the extraordinary and fantastic pro- 

 cesses which are situated on the prothorax. The present 

 species possesses two vertical horns, and behind, the pro- 

 thorax is produced into a pointed, keeled and irregular spine, 

 of equal length with the abdomen. By far the larger pro- 

 portion of the species of this family are inhabitants of the 

 New World, where they assume the strangest and most 

 curious forms." 



Mr. Turner also exhibited specimens of the shells of Helix 

 lapicida, L., from Box Hill. 



Mr. E. Step exhibited specimens of LinincBa peregra, 

 Mull., taken at Wisley, Surrey, ten days earlier. One of 

 these was remarkable, inasmuch as the periphery of the body- 

 whorl was marked by an ochreous streaky band, 2 mm. in
