NOTES ON COLLECTING. 207 
Inne 4th, 8rd day.—First moult. Larve now 2mm. long. Leaf 
eaten right through. - They can erect and propel themselves by means 
of a tubercle at base of last segment. 
June 11th—They are now 4 mm. long and thicker in body. 
June 16th.—They are now 7 mm. long and drop to ground 
to pupate. 
Pura.—I was curious to find out whether the.larve would pupate 
on the leaf like the 2-spot Ladybird (Adalia bipunctata), but not one 
could I find—all had dropped to earth. 
July 6th.—Three imagines emerged. 
July 7th.—Five imagines emerged. 
July 9th.—Dug up and sifted out all the earth, but only one pupa 
to be found. This one had no outer-casing, but the larva had made 
a smooth circular cell—pupa is bright yellow in colour; wings or 
wing cases (undeveloped as yet) plainly to be seen, also antenne. 
Pupa 6 mm. long. Several bristly hairs on head and abdomen. 
July 9th.—Six or seven imagines in breeding cage. 
_Imacines.—The perfect insect is so well known that it needs no 
description. Gastroidea is no doubt a good name for the insect, but 
it does not become “ pot-bellied ”’ until after copulation. 
I hope next year to work out the Life-history of Chrysomela 
fastuosa. The larva feeds on the hemp nettle and is found at the 
same place.—R. Brcx, Barnstaple, 9th Oct., 1920.

A Bresepinc Resutt.—Referring to my previous letter under this 
heading (p. 100), the second alternative suggested by a correspondent: 
in the October number (p. 192), eventually proved to be the solution of 
the matter. 
That the A. alni pupa must be somewhere in the piece of cork, 
naturally occurred to my mind at the time, but as there appeared upon 
inspection to be no apparent aperture or means of exit, the idea was 
dismissed. 
A week or two later, happening again to come across the piece of 
cork, I started to cut carefully into it at what appeared to be a perfectly 
natural crack or fissure in the cork, and some distance in I came to the 
empty pupa case in a comparatively large cavity, hollowed out to the 
exact size and shape of the pupa, the empty case of which filled it 
perfectly. 
That it was possible for the imago to emerge through the extra- 
ordinarily small aperture in the face of the cork, and for the larva to 
have bored out the shaped cavity inside, without leaving a larger and 
more apparent opening, is certainly wonderful.—R. Barnarp Crutcx- 
sHank, Alverstoke. 
Norges on Coxxectine 1 [rary (1918 anv 1919).—(Continued from 
page 100).—Appalingly hot weather throughout June, 1919, in the 
Turin District, in addition to my military duties, made collecting 
sometimes a work of difficulty, however, the following list of species 
captured by me in the district will perhaps be interesting. To economise 
space I use the following abbreviations, viz., R.=Rivoli, a short and 
pleasant trip by electric train from the Stazione Porta Susa; T.=the:
