be the insect called by Oberthiir var. u)ale7i!iis, but as that name was 

 preoccupied by a form of another species of Parnassius it has been 

 re-christened by Stichel liiincola. Of the aberrations of P. apollo I 

 show the one which is perhaps the best known, ab. jiaeudonnviion, 

 distinguished by the two red apical spots. There are in the drawer 

 two forms of /'. apollonius, while of another Asiatic species, P. 

 delpliius, of which there are about 80 named forms, I show six. I 

 would specially draw your attention to the two dark specimens, one 

 of which has been named infernalin by Elwes, and the other, an 

 extremely melanic variety, has been called by Staudinger ab. sf//.r. 

 The species named by Oberthiir P. imperatnr is a fine insect, while 

 the next, /'. harduickii, Gray, is very variable and beautiful. The 

 other species exhibited are P. discobolus, P. ro»iaiiori, P. breineri, 

 and two forms of P. jacijiiemontii."

This was quite a new district to the Society, and but few mem- 

 bers had visited it before. More than a dozen went down together 

 in the afternoon, and in spite of only occasional sunshine a fair 

 number of insects was taken or observed. Several members, but 

 not all, sent lists, of which the following is a summary ; — There 

 were seventeen species of rhopalocera, Pieris braadac, P. najii, P. 

 rapa, Pyranieis cardui, P. atalanta, Limenitia sibijlla, Arijynnis 

 adippe, Drijas paphia, Epinepliele jnrtina, E. tithouKs, Aphantopits 

 liyperantns, Comonymplia pampliilus, Hipparchia seniele, Bitltys 

 quercits, Polyomiimtiis icarua, Adopica flara (thatiinas), and Aiu/iades 

 sylraniis. Larvse of Snierinthi(s ocellatus, Notodonta dromedariits, 

 Sarrothripa revayana [tmdulaniis), and Aiiorta viyrtilli. In the 

 bombyces, Hylophila prasinajia, and Portliesia si)iiilis. A race of 

 Anthrocera trifol'd, Ayrotis striyida, and Iliviila sericealis. The 

 geometers were Acidalia arersata, A. bisetata, F.npithecia lariciata, 

 E. piiiiiilata, and Xanthorlioe (Melanippe) fluctiiata. In the pyrales
