172 THE ENTOMOLOGIST. 
Head, with both transverse and longitudinal depressions, 
finely punctate ; thorax finely punctate, sparsely on the disc and 
rear, crowded and larger on the sides, which are strongly angu- 
late behind the middle and obsoletely sinuate before the angle. 
Elytra rather obsoletely transversely depressed and showing a 
scarcely raised scutellar area; finely lineate punctate. From the 
humerus to the apex the intervals are raised and roughened, so 
that the outer half of each elytra, especially the shoulders, is 
covered with rarsed rugosities ; the apex is lineate costate. Nearly 
allied to Pusilla, Lef., but smaller and differently coloured than 
any of the numerous small forms. I infer from the looks of my 
examples in certain lights that some would be entirely bronze 
above, with rufous shoulders.

NOTES AND OBSERVATIONS. 
THE EMERGENCE OF PigeRIS RAP#.—For some years past I have 
been experimenting on the pigmentation of this butterfly, and last 
season, with a view to carrying on my work, I obtained a few ova from 
the spring brood, metra. I was unfortunate with the larve, as all 
died off except two, which duly pupated towards the middle or end 
of June. However, they did not emerge at the commencement of 
August, and finally I took the boxes containing the two pupe into a 
cold room indoors. To my surprise one of the butterflies emerged 
or November 11th—a day or two after a fire had been lit in the room 
for the purpose of airing it. I promptly took the other pupa out-of- 
doors again, and finally obtained a male imago from it on May 13th. 
The insect is rather small, its markings are pale, the blotches on the 
fore wings almost obsolete, and it would probably pass for metra 
anywhere. I think these two emergences open up the interesting 
question as to whether pup from the spring (metra) brood do not 
occasionally stand over till the following year, and emerge in the 
spring as metra, instead of in early August as rape. In other words, 
are individuals of this and possibly the other Pierides occasionally 
single brooded? I may add that the insect which I obtained in 
November was a fine female, dark cream in colour, the colour 
resembling in tone that of the primrose, without that flower’s greenish 
tinge. I find that as a rule I obtain deep cream or yellow pigmenta- 
tion in about half the insects I experiment with Haroup D. Forp; 
Thursby Vicarage, Carlisle. 
BRENTHIS EUPHROSYNE, AB.—I had the good fortune to capture a 
specimen of B. ewphrosyne on Sunday last in which the orange 
ground was uniformly replaced on the upper side by the palest cream. 
It is almost white. The black markings are slightly heavier than 
usual. The insect is in first-class condition—H. H. Sinus; Sibylla, 
Bray's Lane, Coventry.
