A. pheretes. In the result it appears that the hypothesis was 
incorrect. The larva of A. pheretes possesses a honey gland 
and fans. 
“To the warm weather during August and September it is 
probably owing that three of my larvae have reached the 
last instar, a result not often, I suspect, occurring in this 
species, a distinct effort to produce a second or autumnal 
brood ; I am therefore able to exhibit the larva in the 3rd, 
4th, and 5th (or last) instars. I hope to give a fuller account 
of the early stages in the near future. I may remark that ZL. 
orbitulus also afforded ‘forward’ larvae this season, and I 
exhibit a living butterfly of this autumnal emergence which 
left the pupa on October 2nd ; but Vacciniina optilete, without 
exception, stopped at the 3rd or hibernating instar.” 
In reply to a question whether he had seen ants in company 
with the larva of A. pheretes, Dr. Chapman replied that the 
larvae were bred from ova, so that he had not seen them in a 
wild state, but added that ants were abundant in the locality 
from which the ova came. 
Two TortTRIcIDAE NEW TO Scrence.—Mr. J. H. Durrant 
exhibited two new British species of Rhyacionia Hb. (= Retinia 
Gn. ; Hvetria Hb. Meyr.) 
Rhyacionia purdeyi, sp. n., taken among Scotch firs at Folke- 
stone at the end of July 1911, by Mr. W.Purdey, a very distinct 
species intermediate between sylvestrana Crt. and duplana Hb., 
easily distinguishable from the former by the ferruginous apex 
of the fore-wings and the slightly different direction of the 
fasciae, and from the latter by its more regular and distinct 
striation, as also by its brighter ferruginous coloration, 
which occupies a greater proportion of the wing-sur!ace, 
especially towards the dorsum. 
Rhyacionia logaea, sp. u., from Forres, Scotland (W. Salvage 
and H. McArthur), closely allied to duplana Hb. and posticana 
Ztst., but the much longer ciliations in the antennae of the ¢ 
will at once separate /ogaea from these species. . posticana 
is a broader-winged insect than duplana and logaea, and the 
hind-wings are distinctly darker and less pointed. The type ¢ 
of this new species is the specimen figured as duplana by 
Barrett (British Lepidoptera, XI., pl. 476, fig. 2); the ? is
