Variation. 
Retardai’ion in the Pupal Stage producing Variation. — I 
think I can quote one case in which an insect has become darker in 
the pupal stage. In 1887 I had a batch of ova of Dianthmia cap- 
sincola which hatched early in May, the larvae all grew up together 
there being no appreciable difference in the length of their larval stage. 
About half the batch emerged the following August, and were of the 
usual bright orange yellow. The other half of the batch emerged in 
May, 1888, and were all unusually dark in colour. I have them side 
by side in my cabinet and the difference is striking. — A. W. Mera,

Variety of Gonepteryx rhamni. — I was to-day shown a specimen 
of Gonepteryx rhamni^ having a large portion of the upper wings 
suffused with a reddish-orange colour, shading off to white near the 
tips, the lower wings having also a narrow band of the same tint around 
the edge, and with the markings not quite uniform. The specimen is 
also rather under the usual size and minus the antennae. The insect 
was captured in the lane leading to DarenthAVood two years ago by a 
working man, who knocked it down with his hat, mistaking it for an 
orange-tip as it was flying along. Is not this an unusual variety in this 
country ? — Clement T. Youens, Tower Cottage, Dartford, Kent.

Clostera curtula VARS. — I have some (to me) most extraordinary 
insects, supposed to be varieties of C. curtula. They are rather smaller 
than C. curtula^ and the whole wing is chocolate-brown instead of only 
the tip, as in C. curtula. The lines are, however, almost identical with 
C. curtula. They (six in all) were bought from a man named George 
Rae, of Sittingbourne in Kent, in 1876. He advertised them as C. 
curtula vars. They do not appear to be any European insect, and, as 
they were bought for a few pence, there is probably nothing wrong about 
them. My friend, Mr. Bird, to whom they belong, obtained a large 
number of C. curtula in succeeding years from the same man, but could 
not obtain any more of these vars. On showing them last night at the 
South London meeting, I obtained the valuable information from Mr. 
Carrington that Mr. Farn possesses a specimen with one pair of wings 
normal curtula., and the other representing this variety. It is further a 
hermaphrodite, and must be a most extraordinary insect. It appears to 
have been figured in the Entojuologist some twelve years ago. — A. 
Robinson. March 11th, 1891.
