64 THE entomologist's RECORD. 



His best capture, however, was a i\ne (/.cdiim var. helicc, which was 

 flying high up the side of the tSteinenalp ; surely a strange locality 

 for this, being well over 7000 feet. We had a successful day at the 

 fifth refuge. We worked the ground shown in the second photograph, 

 above the road. Here the great creamy, lazy-flying ParnasKius delitis 

 was in some numbers, including one female, which fell to my son. 

 Then the Coliads were in evidence. ( 'tdiaa phicoinoni' was fairly abun- 

 dant. I made a wild overhead shot at something that was coming 

 down hill at express speed, and found, to my great delight, that I had 

 netted a fine male C. palaeno. The first sight of the lovely crimson 

 fringe of this charming species is not easily forgotten. We also ob- 

 tained specimens of Bimthis palfs, Polyoinmatua pliercteA, C/iri/sophaniis 

 var. curyhia, Erehia yorni', E. tyndarw^, Melaiiipias epipliron, AntJto- 

 cJiaria helia var. siiiijdonia, and Cotmoni/iiip/ia arcania var. dartviniana. 

 Brenthis fnphronijne was abundant. 



Our last day in the district was spent at the top of the Simplon 

 Pass. ( 'olias jdurounmc was abundant — all males, however— and of 

 (.'. palaeno we netted a dozen fine specimens, halt of each sex, and in- 

 cluding a perfect yellow female, var. nrrdandi,! believe. Brcnthis pales 

 was frequent, also Mditaea aiirinia var. uierope, and M. parthenie var. 

 varia. My son took two fine Parnassiufi delim. Pieris callidice was 

 common, and we obtained specimens of Erebia lappona, E. (jorge, E. 

 tyndanis, Li/carna avion var. obscnra, L. alcon, PolyommatuH orbitulus, 

 P. o]itilete, not, however, in good order, and Cnenonympha var. dar- 

 uiniana. Breiithiti eujihrosyne, was, however, the most abundant 

 species seen, and was quite fresh. 



The next day, July 12th, we left Brigue by the early morning train, 

 getting off at Aigle, with the object of obtaining, if possible, Apatura 

 iris along the Le Hepey road. We were not successful in this, al- 

 though each of us did see one specimen, but we found many other 

 things we were in want of. The most abundant species seen was, 

 undoubtedly, Theela iliris, which was sucking the flowers of lime trees 

 and also wild thyme in great numbers, and was in good condition. 

 Satynis hertnione was abundant, sitting on rocks or in the road, and 

 the males of ]>ryas paphia made a good show. We obtained about a 

 dozen of a much wanted insect, Paranje achine, in good condition, and 

 amongst other species taken were Pclyyonia r-alhum, Parnassins apollo 

 (common), lAwenitis syhiUa, T/iynieliciis thainnas, PaiiipJdla syhaniis, 

 and Aryynnis adippc. The brilliant Polyowntatus dniiion was just ap- 

 pearing, and we bagged two perfect males ; the same remark applies 

 to our old friend /'. rorijdon, of which we obtained three or four 

 males. 



After dining at Lausanne we travelled straight on to London, ar- 

 riving on the evening of .July IHth, having spent, certainly, the most 

 enjoyable and interesting entomological holiday of my experience. 



A New British Flea: Ceratophyllus londiniensis. {With Piatt). 



By Hon. N. CHARLES ROTHSCHILD, M.A., F.E.S. 



Ceratophyllus iDtidiiiiensis, sp. nov. — This species is allied to C.fdsciotun and 

 resembles that insect in the absence of the eighth sternite in the male. It ditfeis, 

 however, in being much smaller and paler, and having more lateial bristles on the 

 hind libia. The sexual apparatus of the male, moreover, and the seventh and eighth 

 abdorahial segments of the female are abundantly distinct from those of C. fasciatus.
