16 THE ENTOMOLOGIST. 
till this space was full, when the case burst in the usual place, 
and the insect walked out; there was no wriggling or con- 
tortion during the operation. I had frequently observed this 
fluid in the recent cases, but had no idea of the use the 
insect had made of it in expelling itself from its envelope by 
its means. Readers acquainted with the pressure of fluids 
will understand the comparatively immense power an insect 
may have in this way. As I had several hundred pupz of 
Bembeciformis and Typhe I had frequent opportunity of 
observing the process, and these moths emerge at a convenient 
time, from eight to twelve o’clock a.m., for observation. I 
also remarked that when the pupe of Typhe were removed 
from the support of the stem of the food-plant the abdominal 
segments of the case were forced off, the anterior remaining 
on the insect, but when supported this did not happen.—

In the matter of Lathonia, Leucophea, and Albipuncta 
(Entom. vi. 563).—I have sent you the dates and localities of 
the three above-named insects, all taken within fourteen miles 
of Canterbury, as I see by the December number of the 
‘Entomologist’ many specimens of the above-named insects, 
in fact the majority of those sold as British were nothing but 
continental, and the three insects named I have no hesitation 
in saying have their head-quarters in this locality. The first- 
named I took the first year I collected, which is about seven- 
teen or eighteen years ago, when my father, brother and myself 
took nineteen, all of which Mr. Cooke, of New Oxford Street, 
had alive, as he was collecting in this locality. I did not see 
it again until 1868, when I took thirteen. Since then I have 
taken it every year, and believe I shall continue to do so. As 
to Pachetra leucophza, the first I ever saw was taken by 
myself on June 13th, 1872, which was a female, and not 
knowing the insect I forwarded it alive to Mr. Stevens, who 
named it for me. I then worked hard to find more, and tried 
the next night, when I only found one poor specimen, which 
was flying at the top of the long grass. I then tried sugar, 
and the first time I sugared, which was a Saturday night, I 
took twenty-three, out of which there were only four bad 
specimens; the others were as good as bred. I sent an old 
one alive to Mr. Bond, also a second to Mr. Newman. I also 
took two on the 19th and one on the-2lst. All the above I
