they are of a full golden-yellow colour, perhaps slightly greyer-tinted 
dorsally, but practically unicolorous ; the head black. In form, they 
are hardly more than normally elongate, and thus do not at all agree 
with those of Lygris. I regret that I have no detailed notes on this 
stage. C. fulvata is not generally subject to much variation, but the 
Scotch form is much larger, and decidedly paler than our English one. 
The only striking aberration which I remember to have seen is in Mr. 
Sydney Webb’s collection, and is figured by Mosley (T ar. Brit. Lep., 
Cidaria, pi. iii., fig. 3) as being “ in Mr. Bond’s cabinet, from the Isle 
of Man ” ; the central fascia is narrow and strongly interrupted in 
the middle, in a manner somewhat parallel to that of an extreme ab. 
ruptata of C. corylata. 
Eustroma silaceata, Tib.—I have already confessed my complete 
ignorance of the earliest stages of this species, and should have omitted 
all further mention of it but that it seems worth while to correct a slight 
error into which Prof. Aurivillius has fallen. In an article in Ent. 
Tidskr., xviii, pp. 139-174, on the Lepidoptera described by Fabricius 
from Danish collections, he identifies Phalaena posticata, Fb. (1794), 
with silaceata, Hb.—as indeed was already done by Strom in 1866, 
Nat. Tidsskr. (3), iv, p. 196)—and on p. 508 gives priority to the name 
posticata ; apparently overlooking the fact that Hiibner first figured 
silaceata in 1793, in his scarce work, “ Sammlung auserlesener Vogel 
und Schmetterlinge,” even if we do not go back to the origin of the 
name and the very defective description, in the “Vienna Catalogue” 
of Schiffermiiller and Denis. The only case under which the name 
posticata, Fb., will be likely to come into currency will be if Laspeyres’ 
doubts as to the identity of silaceata, Schitt'., and Werneburg’s determi¬ 
nation of it for the closely-allied capitata, H.-S., should be allowed to 
override the action of Tlubner and Treitschke, in which case the 
synonymy would work out as follows : 
1. Silaceata, Schiff. (1775), Wrnbg., nec. Hb.; capitata, H.-S. 
2. Posticata, Fb. (1794), Strom, Auriv. ; silaceata, Hb., et auctt., 
nec Schiff. 
The named aberration, insulata, Haw., is theform in which themiddle 
part of the central fascia is insulated from the rest of it, by the curved 
whitish lines which cut across it. A second named form, not given in 
South’s List, and apparently entirely alpine and boreal, is var. 
defiarata, Stgr., diagnosed as “ absque colore flavido.” 
Lampropteryx suffumata, Hb.—I have already referred to this as 
an evident alien to my tribe Cidanidi. Captain Vipan kindly supplied 
me with the eggs last May. They were laid singly or in twos (in one 
instance a clump of four) on the sides of the chip box, pretty firmly 
attached. They were mostly somewhat tilted, and one or two (quite 
casually) were in an almost upright position. When first laid they 
are very pale yellow, highly polished. After a few days they become 
darker yellow. They are oval, blunted off' at both ends, hut with no 
hint of the truncate form characteristic of Lyyris ; one end very 
slightly broader than the other, depth not much less than width ; 
depression on upper side slight. They are covered with uniform hexa¬ 
gonal reticulation, which hardly seems to be more than surface-deep. 
There is a small hut tolerably deep depression at the narrower (? micro- 
pylar) end ; mieropyle not discernible. They hatch in about three 
weeks, having changed to a rather dark grey-brown two days before.
