202 THE ENTOMOLOGIST.

Colias Hyale—Is it Double-brooded ?—Noticing several 
records of the occurrence of C. Hyale and C. Edusa in the ‘ En- 
tomologist,’ ‘ Field,’ &c., for this year, as “ early appearances,” 
the question suggests itself whether it is generally thought 
they are specimens of a spring brood: this, I think, is 
undoubtedly the case. Last autumn Hyale was especially 
abundant in this neighbourhood; and Mr. G. H. Raynor had 
the good fortune to see one female deposit six eggs, which he 
collected. From this we can infer that the species does not 
hybernate; and from its appearance in May and June, and 
again in August and September, it must certainly be a double- 
brooded species, the spring generation, as with many other 
species, being much the rarer. My earliest Hyale taken this 
year was on the 10th June,—a beautifully fresh specimen ; 
and since then I have seen five or six others. Last spring 
many specimens were seen and taken. It was abundant in 
the autumn that year. Should the weather be favourable we 
may expect a plentiful supply of the autumnal brood of both 
species—C, Hyale and C. Edusa.— Edward A. Fitch ; Maldon, 
Essex, August 7, 1876. 
Food-plants of Gonepteryx Rhamni.—After the statement 
of such an experienced entomologist as Mr. E. A. Fitch 
(Entom. viii. 302), that Gonepteryx Rhamni could be reared 
on “apple, pear, and medlar,’ I have this year made the 
experiment ; and—whatever they may do in a wild state—in 
confinement, in this locality, the larva of this insect will not 
partake of any of these trees. Mr. G. C. Bignell was good 
enough to send me a larva, and I at once, and “ without 
much trouble,” set before it a tempting supply of the three 
trees mentioned by Mr. Fitch, leaving also a small portion of 
a somewhat dried-up leaf of buckthorn. By the following 
morning the scrap of buckthorn was entirely devoured, and 
not one of the other plants was touched. Having no buck- 
thorn procurable in the neighbourhood, I sent to Mr. W. 
Holland, of Reading, for some; and for a day or two poor 
Gonepteryx Rhamni was left with nothing but the stale stalks 
of its natural food-plant. Apple, pear, and medlar, were all 
supplied with total unsuccess; not a particle was tried or 
tasted; and the unfortunate larva was compelled to seek a
