NOTES AND OBSERVATIONS. rial! 
Eupithecia larvee were common on Galiwm, Artemisia, and Senecio. 
Dusking was not very successful, and sugaring on the cliffs was 
unproductive during the greater part of the month. By far the 
most common insect at sugar in the Courtenay Woods was Amphi- 
pyra pyramidea, which came freely during the last days of our 
visit. On one occasion five were successfully boxed from one patch. 
Four Lymantria monacha came to the lantern one night in a pine 
wood. The flowers of Senecio near the sea were not worth working, 
although in 1912 at Sutton-on-Sea common species swarmed on it.

Morus CASUALLY PASSING MORE THAN A YEAR IN THE PUPAL 
Srate.—Mr. Robert Lawson’s note upon some examples of Bzston 
hirtaria, which spent nearly three years as pupz with him (Entom. 
xlvi. p. 332), interests me much, as I have long suspected that to 
something of this kind may perhaps be attributed the extra 
abundance of certain insects in certain years so often remarked 
upon. I have had several species of caterpillars from time to time 
in my rearing cages, that have missed the usual time of emergence, 
and duly turned to imagines in the following year; but will, mean- 
while, only mention one case which is curiously like that referred to 
by Mr. Lawson. In August and September, 1888, larvee of Notodonta 
ziczac happened to be unusually numerous round Berwick-on-Tweed, 
and a number of them were transferred to the breeding cages, 
Most of these duly emerged in the following year, from May 22nd up 
to July 14th, but a few pupe remained alive in the cage till 1891, 
when one perfect insect emerged from one of them on July 18th, 
none of the remainder being then alive. But the point I particularly 
wish to emphasize is that, although upon the poplar trees from 
which the larvae had been gathered in 1888, no ziczac caterpillars 
appeared in either 1889 or 1890, in the autumn of 1891 they were 
again numerous. It might, of course, have been no more than a 
coincidence, but it strongly suggested some conditions, climatic or 
otherwise, especially favourable to the species, and common to the 
years 1888 and 1891; as well as that certain of the wild insects might 
also have passed the intervening two summers in the pupal state.—

LITHOSTEGE GRISEATA SECOND Broop.—I had a few larve of this 
species last year which duly pupated, and I was much surprised to 
find on looking at the cages in September that five moths had 
emerged (two males and three females). They had evidently paired 
and laid, as there were some old eggshells about, but the larvee had of 
course perished. This may account for the scarcity of the species 
some seasons, as if there is a second emergence the resulting larve 
would surely perish, as the S¢symbriwm would be dying and the seeds 
fallen before the larve could feed up.—H. M. Eprtstren; Forty Hill,

“THE VERRALL SuPPER.”—No entomological event of the year, 
as we have before asserted, is of greater social interest or of more 
value for founding friendships than the “ Verrall’” supper, which 
annually perpetuates the memory of those given by the late G. H. 
Verrall and that of the donor. In 1913 the number of guests was
