26 THE ENTOMOLOGIST. 



to see that Argynnis Lathonia has turned up in several 

 places, and especially in those spots where its former appear- 

 ance was so unnecessarily discredited. If Polyonimatus Hip- 

 polhoe does not turn up very soon, it will be considered 

 foreign, and share the fate of Melitaea Dia. Poor Weaver, 

 one of the best field Entomologists and a very accurate ob- 

 server, always thought he was hardly used respecting M. Dia, 

 and a good many Entomologists agreed with him. He 

 was a most persevering collector, and the first to bring to 

 notice many of the scarcer insects, and his word was never 

 doubted except about M. Dia ; but in that case the authori- 

 ties had pronounced that M. Dia had not occurred, or ought 

 not to have occurred, in England, and Weaver's evidence was 

 ignored. When I first brought Chilo obtusellus, cicatricellus, 

 paludellus, or whatever its name now is, from the Norfolk 

 fens, and showed it to a distinguished Entomologist, he at 

 once stated that it must be North American ; not that he 

 knew the insect, but it was there, and, as it was impossible 

 that a Tinea (for it was so classed then) could presume to be 

 British without his knowing it, it was assigned to the first 

 country that happened to occur to him. — E. C Buxton ; 

 Daresbury Hall, Warrington, January 13, 1866. 



[A few notes on Mr. Buxton's paper may possibly possess 

 some interest. 1. Pyrochroa pectinicornis is now in most of 

 our collections, and, although unique when discovered by Mr. 

 Buxton, has long ceased to be so. 2. The larva of Chorto- 

 bius Davus is known ; it has been fully described, and has 

 been figured by Mr. Buckler. Some of the Scotch Entomo- 

 logists ought to find the larvaj of C. Typhon, Haw., and send 

 them to this gentleman : this is the only way in which the 

 disputed point, as to their being species or varieties, can be 

 satisfactorily settled. The specimens of C. Davus taken in 

 the south of Cumberland have the ocelli on the under sur- 

 face of the posterior wings much smaller than those taken 

 near Manchester : this form does not appear to be found in 

 Scotland. In Orkney and Shetland the female specimens of 

 Typhon are very pale, almost white ; and the Isis of Zetter- 

 stedt, found in Lapland, is the extreme northern form, not 

 being much larger than Pamphilus, very pale in colour, and 

 generally, if not always, without any ocelli on either surface 

 of the wings. 3. An Erebia was figured by Knoch in 1783,
