growing on the walls by the roadside, made it quite evident that these 

 specimens were not to be the hybernators. The males are smaller, 

 and, when in fine condition, brighter than the females. P. c-album. — 

 One specimen only, netted whilst on a head of J'hiiHitoriun. Evidently 

 just emerged, and with dark underside. Have all hybernating 

 P. c-albuin a dark underside ? Limcnitis Camilla. — This charming 

 insect was not at all common, but its graceful flight along the 

 edge of a wood, or as it sailed round a head of luijiatoiiuin. already 

 covered with Calliinorpha hem, was delightful in the extreme. Speci- 

 mens, otherwise in the very finest condition, almost always had a 

 tooth nipped out of one of the hind-wings. 



Ai'ATuiuD^. — Apatuia ilia. — One male specimen taken on the road 

 to Bussoleno, during a gleam of sunshine, on an otherwise dull 

 morning. It settled on the damp road, and at first I thought it was 

 a fritillary, so brown was it, but as soon as it moved so that the sun 

 shone on its wings, the purple iridescence disclosed its identity. I saw 

 no other specimen. 



LiBYTHEiDyE. — Libytlwa ciitis. — It would appear as if I am doomed 

 not to take this insect. I had a view of a specimen of this species as 

 it Hew within a yard of me. I hesitated a moment, and the butterfly 

 was gone. 



Satyrid.e. — Pararr/c eijeria. — A few specimens only in a wooded 

 gorge. Of an intermediate form between the bright fulvous form of 

 southern Europe and the northern form, as exhibited by our British 

 specimens. P. nu'i/aera. — Abundant and brightly tinted. It occurred 

 along the roadsides, and occupied exactly the same ground as the fol- 

 lowing species. P. inaera. — Very abundant on all the roads just 

 outside the town, but difficult to obtain in fine condition. The female 

 specimens were particularly well-marked with fulvous on the upper 

 side, some having this colour carried almost to the base. On the other 

 hand, some of the males were small anddark. Kpinejiluic ianira. — Rather 

 abundant on the bramble blossom here and there, a few of the yellow 

 aberration of the female occurred. Ilijipairhia sfnieli'. — The form here is 

 very large, the underside of the male white-banded, of the female 

 covered with grey marblings ; the male very uniformly tinted above, 

 the female of the aristaciui form. This species abounded on the road 

 leading up to the Mont Cenis pass ; I saw many hundreds on the 

 flower heads one morning. //. statilinus. — This beautiful fellow was 

 rather rare. At Aosta it loved dry rocky watercourses ; here it was 

 found occasionally on the hhipaUniutii flowers by the roadside that is 

 crossed by the railway, Avhilst on the Mont Cenis road it kept to the 

 ground where it was most difficult to see. //. arcthiuia. — Kane gives Susa 

 as a locality, and I, at first, thought I had missed the species. He also 

 says the form taken here is the var. bnabdil, diagnosed as " darker 

 brown with tawny band much obliterated and underside paler, with 

 whitish rays very distinct." All I can say is that the female has a very 

 pale yellow band, the males a well-marked orange one ; wiUi a snuill spot 

 in the third interneural space above the inner margin. The underside 

 has the nervures outlined with pale, about as strong as is usual in the 

 specimens that I have captured at Aix-les-13ains. This species is ex.- 

 cessively local, and occurs, so far as I could discover, only on the steep 

 slopes on the Mont Cenis road. Here it settled with swarms of //. siuicle 

 on the flowers (greenish) of a kind of thistle, that is very attractive to 

 insects of all kinds, ('alliniaijilta Itcra swammd, in 18'Jl, on similar
