two rows of tawny spots, one on the hind margin and the 

 other parallel with it. This variety was taken in the New 

 Forest, July 20th, 1897. 



Mr. Nottle exhibited examples of Agrotis tritici and A. 

 agathina, from Keston, 



Mr. Barnett exhibited a living female example of Nyssia 

 hispidavia, from Chingford. 



Mr. F. Noad Clark exhibited several species of ticks, and 

 contributed the following notes : — " Some weeks ago I 

 received from Mr. Hewett, of York, the two specimens 

 exhibited. He described them as parasites which he found 

 on guillemots on the Yorkshire cliffs. On examination I 

 found them to be ticks, but as they were unlike any I had 

 previously seen I came to the conclusion that they were 

 ' something new.' I sent them to Mr. Wheler, of Alnwick, 

 who is an authority on the ticks, and he at once pronounced 

 them to be at least a species, if not a genus, new to Britain. 

 At his suggestion I sent them to Prof. Neumann, of Toulouse, 

 who is the Continental authority on these ticks. He was 

 exceedingly interested in the specimens, one of which, a male 

 Ixodes Jiinbi'iatus* he had never before seen. He tells me 

 that it had been described b}- Kramer and Neumann in 1883, 

 who captured it during the Vega Expedition. It has never 

 been recorded in Britain. It appears to favour migratory 

 birds, which will account for its being found on the 

 guillemot; and there is no doubt that it had come from 

 remote regions. 



" The other specimen, a distended female, is Ixodes horealis, 

 Kramer and Neumann, or Ixodes ptitns, Cambridge, and is 

 also found on migratory birds, and has been taken as far 

 apart as Alaska and Cape Horn. 



" I also exhibit seven specimens, nymphs and adults, of 

 the common British tick, Ixodes reduvius, for comparison. 

 These are found on cattle, deer, and sheep ; to the latter they 

 are a terrible pest, and the cause of a destructive disease 

 called ' louping-ill.' They have also been found on birds, 

 hedgehogs, moles, and bats, and even on reptiles." 



Mr. Clark further exhibited photographs oi Ixodes fiinbriaUis, 

 showing ventral and dorsal aspects. 



Dr. Chapman exhibited a living bred specimen oi Dimorpha 

 {Endvomis) versicolora, and some pupae in the larva cases of 

 Thyridoptcryx ephenieviformis. 



Mr. Edwards exhibited very fine examples of Ornithoptera 



* This species is now known as Ceratixode pittiis.
