302 THE ENTOMOLOGIST. 
ON BREEDING VARIETIES OF ANGERONA PRUNARIA. — Con- 
tinuing my observations on this subject (Entom. xviii. 254), I 
regret that of the fifty larva referred to I only succeeded in bringing 
to maturity a single example of A. prunaria, whose progenitors 
were the speckled variety of the female and the orange-banded 
variety of the male already described. This example proved to 
be a palish and somewhat degenerated female of the ordinary 
variety of that sex, of the fourth and inbred from the third 
generation. ‘I'his degeneration evidently arose from two causes, 
viz., interbreeding, and an enfeebled condition of the female —the 
latter cause resulting from some hesitation on my part whether 
to kill the insect for the cabinet or run the risk of spoiling the 
specimen in experimenting with it. Thus I conclude that had 
the female been unimpaired, the results of interbreeding would 
at this stage have been scarcely, if at all, apparent, and the fifth 
generation attained without any very sensible diminution in the 
size and vigour of the race. On the other hand, in the absence 
of an infusion of new blood, the effects of interbreeding with 
this insect would be no doubt apparent in the third and decided 
in the fourth generation, even were the interbreeding to take 
place under the most favourable conditions. Though the 
continuity of my experiments have been intefered with, I am 
happy to say that through the kindness of a friend, to whom I 
had given a brood of the larve of this moth in March, 1885, I 
have been enabled this year to resume experiments; but another 
season, or perhaps two, must necessarily elapse, before I can look 
for notable aberrations or new varieties—ordinary varieties only 
having resulted from the resumption of experiments. Of these 
varieties I effected pairings as follows:—ordinary female with 
speckled variety of male; ordinary female with orange-banded 
variety of male. I should mention that, owing to a considerable 
interval, about three weeks, elapsing between the emergence 
of the moths from which the above-mentioned pairings were 
effected, and the single experiment—remnant of the first series 
of experiments—I was not able to affect a pairing with the latter. 
I am, however, still in hopes, at no very distant date, of being 
enabled to record the variation looked for.—Gro. J. GRAPES;
