DoUBLE-BROODED GeOMETRIDES. DIFFERENCE BETWEEN AciDALIA 



OCHRATA FROM DeAL AND DauPHINE. 



By J. W. TUTT, F.E S. 



Geometrides. — Metrocampa man/antaria. — One specimen only, in 

 good condition ; second brood evidently. Exactly like our British 

 examples. ludis trrnaiia. - One beautiful example came to light. It 

 is, probably, a very abundant species in the district, as clematis 

 grows everywhere. The species had been abundant in Kent in late 

 June, so we suspected this must have been a specimen representing a 

 partial double-brood. This is not known to occur, we believe, in 

 England. Xonoria poninata. — Of this little emerald, one specimen 

 only, taken in a lucerne field. Exposure had, however, changed it from 

 green to brownish. Sdidoscina ericctaria (plwiiaria). — One specimen 

 only, in a lucerne field, a large male. This species is doubtfully double- 

 brooded in Dauphine and Southern France generally. We found the 

 species moderately abundant on a piece of heathy ground at Gresy- 

 sur-Aix, towards the end of August, in 1894. Eiiiatun/a atojiiaria. — 

 This species, partially double-brooded in England, becomes evidently 

 wholly double brooded here. It was very abundant for the first two 

 or three days of our stay only, when it became scarce — evidently over. 

 The examples were large, with bright fulvous ground-colour, and very 

 variable, in the direction of developing a bright yellowish coloration. 

 The females were very fine, large and variable, and also roughly 

 dimorphic, one lot grouping into fulvous forms, the other into grey. 

 Strcnia clathrata. — Rather common, the ground-colour usually 

 white ; we observed no specimens of the ochreous colour so 

 common with us in England. Stirnia iiJimorata.— A few worn ex- 

 amples only, more like the ochreous Lewes examples, than is the grey 

 form from Le Lautaret. The <? specimens were worn, as might be 

 expected, considering the species was coming out a fortnight before at 

 Le Lautaret (8000 ft. elevation) ; the females were in better condition. 

 They disappeared entirely after our third day, so the species was 

 evidently over. Aspilatcs (jilvaria. — Rather common, and exactly like 

 our British specimens. ]\Unoa murinata. — One example only of the same 

 brown form that we usually get in England. The grey form appears 

 to be much rarer. It was the only form, however, seen at Bregenz, in 

 August, 1895. Anaitis plai/iata. — One very large and beautiful speci- 

 men disturbed. Very like a specimen captured on Ben Donich 

 (Loehgoilhead), in August, 1893. Kuholia hipunctata. — Very abun- 

 dant, and rather darker than our Kent examples. I'dun/a cnniitata. — ■ 

 One worn specimen only came to light. Caiiiptoi/raiiniia hilincata. — 

 Common in one or two spots. A pale form, inclined to greyish, Avith 

 no distinct dark bands. Most of the specimens were worn, and the 

 species was going over. Melanipix' Jiuctuata. — Very like well-marked 

 London specimens might be, with the basal area, costal and
