era! beetles in a cage containing grow-
ing peas in which the seeds were about
one half grown. Dec. 10, several eggs
were laid on the outside of one pod in
the same manner as upon the dry -seeds.
No eggs were laid upon any other pods
although there were several in the cage ; and as time passed and the eggs that
were laid did not hatch, I began to think that they must have been unfertilized.
But as they held their shape and color I left them, and how wonderful has been
the result! The pod ripened, turned
yellow, and the vine was nearly killed
by plant-lice and mealy-bugs. Finally,
in the latter part of January, 1893, I
picked the pod and placed it in a box
to wait events. After it had been in
the box for about a week, I examined
it and what was my surprise to find that the brown heads of the larvae were
plainly visible through the shells of
several eggs. The eggs were hatching !
The pod and its seeds were quite hard
and nearly ripened. Fifty days had
elapsed since these eggs were laid ; and we have seen that ordinarily on dry
seeds the eggs hatch in less than twenty days.
What unseen hand was it that held in
abeyance the development of the embryo
in the egg until the pea had reached
the ripening stage-the only stage
when it seems to be fit for the food of
the larva?
How interesting and won-
derful are Nature's ways as revealed in
the lives of some of the tiniest of her
creatures !

PSYCHE.
AN UNDESCRIBED SPECIES OF VESPA.
Assistant in the Entomological Department Oxford University Museum. Having lately been occupied in ar-
ranging the wasps contained in the
Hope Saunders and Smith's collection
I have come across a curious species
which has not been mentioned by either
Saussure or McFarland, so I venture to
describe it here as a new species in
honor of Professor Westwood through
whose kindness I am able to devote my
time to the study of entomology.
This is the only true Vespa which I
know whose colors are bright dark red

BRIEF NOTES ON TWO JAMAICA
PAPILIONIDAE.
BY T. D. A. COCKERELL.
SYNCHLOE JOPPA.-JU~~ 14, 1892, 1 saw a
female ovipositing on a sweet scented sticky Cleome, having a hairy stem, the leaf with five hairy or pubescent leaflets. The egg was laid on the under side of the leaf near the tip. Egg about I mm. high, long, cylindrical, shiny pale yellow, truncate above, with twelve strong vertical ribs and numerous small
weak transverse riblets. It was not attached other than by the secretion of the hairs of the plant; from the abundance of glutinous hairs on the leaf it would be hard to attach it in any other way.
PAPILIO ~~~~us.-Larva,e about to pupate
found on Prickly Yellow, July 13, 1892.
About 4 cm. long, stout, cylindrical, but first and last two body segments smaller. Head shiny brown with a whitish spot on each side of crown anteriorly. Body dark brown. A
pair of short subdorsal tubercles on each of the four first body segments those on the first ocherous; side of body with a broad dash of creamy white marbled with gray on 5-7th body segments and some of the same color on sides of 10th and nth segments. Abdominal legs pale gray, blotched exter- nally with darker. Thoracic legs brown.
