LEPIDOPTEKA OF AIX-LES'BAINS. 235 



with the two foregoing, and in fine condition. Cueiioni/inpha arcania. — 

 Large, typical form. Some specimens flying along the paths and over 

 the brambles and bushes in the same way as E. tithonm, which they 

 resembled very closely. I also saw the females in a rough grass field 

 ovipositing. The latter were in much poorer condition than the 

 former. Enndia hi/pcrantkm. — Common on the roadside between 

 Gresy and Aix-les-Bains, but pasne. The females were remarkably 

 well ocellated. Melanan/ia ijalathca. — In great abundance, but quite 

 jmsse. I do not think I saw a really good specimen. 



BoMBYciDES. — Pnrthctria dispar. — In untold profusion. The males 

 were everywhere, flying madly over the bushes, or zigzagging in the 

 lanes with E. hjcaon and E. ianira. No females seen. Euthemonia 

 rmsula. — Second brood just appearing. 



Geometrides. — Acidalia rufaria and A. ochrata. — I should be 

 inclined to refer the males of a species captured among the sainfoin 

 to the former, and the females to the latter species. I see the two 

 species have been telescoped at the British Museum. Yet even in the 

 long series there, I find no specimens just like mine, and am not at 

 all satisfied yet that the two sexes of my moths do not belong to two 

 species. Acidalia mnniliata. — Going over, only one or two specimens 

 observed. Acidalia Jiuniiliata. — Not uncommon, but too worn to be 

 worth collecting. — A^thena candidata. — A few specimens of a second 

 brood occurred. Eubolia bipuuctaria.- A somewhat dark grey form 

 was not uncommon. Gnophoft fnrvata. — Several specimens of a huge 

 Gnophid were disturbed, and one captured. I am not at all certain it is 

 this species, as it is very different from our dark Mendel Pass specimens 

 of G. furrata. This was in poor condition, and very pale. 



NocTuiDEs. — Eiuiidia [/li/jdiica. — A form with rather dull-coloured 

 fore-wings and somewhat suffused hind-wings was observed. Acnntia 

 luctiwsa. — A few specimens noticed in a stubble field. 



Pterophorides. — Aciptilia tetrad act ijla was the only plume observed. 



Pyralides. — />o<//.s rubit/indftalis. — This was abundant on the 

 sides of the pathway leading through the wood. IJoti/s fnscalis. — 

 Common in the same locality as the last. Endotricha jiaiiDiicali^. — 

 A few specimens disturbed from the undergrowth. Craiiibus fahcllus. — 

 A pretty pale form, with very white ground colour, was abundant in 

 the same locality as the last. 



TiNEiDES. — Phnirnta ><chlac<icrclla. — Not at all uncommon among 

 the junipers. 



Zyg.enides. — These were in full force, and here and there were in 

 countless profusion, all the species mentioned sometimes occurring on 

 the same flowery bank. I saw no cross pairing. Ziji/aena carniolica.— 

 Very abundant, and very variable. The following aberrations were 

 taken, viz.—{l) ab. diniemis, found commonly here, (2) ab. hcdnmri, 

 not uncommon, (3) ab. intciinedia, not common, (4) ab. beroliwnsis. 

 This last aberration, with ab. dinicmiH, made up the bulk of the captured 

 specimens. The fully cream-ringed type was rather rare, and on the 

 whole, the specimens incline to be devoid of this characteristic marking 

 of the type. As a race, therefore, the Aix specimens tend towards a 

 form with the red markings not strongly ringed with ochreous. There 

 is also a strong tendency for the two red basal and the two red 

 central spots to coalesce. Zi/i/cwna achilleae. — Common, but showing 

 no marked variation. Zijgaena tramalpina. — Not common, and not
