reached Europe, we append the fol- 
lowing extract: — 
Aspidisca. 
“ Fore wings with no discoid al cell. 
The subcostal nervure traverses the 
middle of the wing, attenuated from 
the base to the basal third, where it 
gives origin to a long, marginal branch, 
which reaches the costa at the apical 
third of the wing ; near the tip it sub- 
divides into three short branches, one of 
which is delivered to the costa behind 
the tip, one to the tip, without attaining 
the extreme apex, and one to the inner 
margin, somewhat behind the second 
marginal branch. The median nervure 
is wanting. The submedian simple. 
Hind wings with no discoidal cell. 
The subcostal nervure is central and 
attenuated towards the base, and at 
about its apical third delivers a branch 
to the inner margin, and is bifid behind 
the tip of the wing. The median is 
simple. The submedian obsolete or 
wanting. 
“ Size extremely small. Head and 
face smooth, covered with closely ap- 
pressed scales. Face rather broad and 
somewhat produced beneath into a point. 
Forehead rounded. Ocelli none. Eyes 
extremely small, not visible from above, 
and scarcely visible in front. Antennae 
held extended at the sides, very short, 
scarcely one-half as long as the anterior 
wings, rather obtuse and roughened with 
scales. Maxillary palpi none. Labial 
palpi none. Tongue none.” 
Then follows the description of the 
imago of A. splendoriferella, which we 
omit. 
“ The larva mines the leaves of Cra- 
tagus tomentosa early in September. 
The mine appears at first as a very 
narrow line, and is subsequently ex- 
panded into a small, transparent blotch. 
At maturity the larva weaves a cocoon 
between the cuticles, and cuts out a 
small oval disk. This is sometimes car- 
ried quite a distance, and is ultimately 
secured to some object by one of its ends 
tied down on a little button of white silk. 
It enters the pupa state towards the latter 
part of September, and appears as an 
imago early in spring. 
“ The mature larva has a head much 
smaller than the first ring, rounded above, 
and elliptical. The body is flattened, 
and tapers posteriorly from the anterior 
rings. The segments are rather deeply 
incised, the thoracic obtusely rounded at 
the sides, and the rest with a minute 
lateral nodule or mammilla. It is with- 
out legs or prolegs, but on the second 
and third thoracic rings, on both the 
dorsal and ventral surfaces, are spots or 
cup-like depressions, one on each side, 
capable of being contracted and expanded. 
So, likewise, from the sixth to the ninth 
inclusive, on the ventral surface are 
transversely placed oval spots, similar to 
the thoracic, and one on each segment. 
On the segment next the last is a pro- 
tuberance, both dorsal and ventral, with 
two cup-like depressions on each surface. 
These are not supplied with hooks, and 
if they are substitutes for feet must act 
like suckers. They are all pale brown. 
The head is dark brown ; the body brown 
with blackish spots along the dorsal and 
ventral surfaces. 
“ When the larvae are young it is ex- 
tremely difficult to discover their mines, 
and the transparent blotch is not much 
larger than the cocoon, leaving a space 
in which the ‘ frass ’ is collected.” 
A SINGULAR Hybrid. — At the meeting 
of the Entomological Society yesterday 
evening, Mr. Henry Cooke, of Brighton, 
exhibited a singular hybrid of the genus 
Ephyra; it had been obtained in the 
following manner: — Out of a number of 
specimens of Ephyra orbicularia and
