prove the same species, both from the food-plant and from my 
having taken the insect in the same locality. I have also observed 
in the larve that if they are touched when crawling they imme- 
diately draw themselves into their cases, and after a time appear 
at the other end and crawl away in an opposite direction. The 
cases appear to be constructed in two pieces or halves, as it 
were, merely fastened together in the centre where constricted, 
and which acts like a hinge, so that when the larva protrudes 
itself from one end it causes the other end of the case to become 
securely closed—a very wise provision against all marauding 
intruders.—Gero. EnisHa ; 122, Shepherdess Walk, City Road, N. 
CoLLEcTION oF Economic Enromotocy.—A valuable “ Col- 
lection illustrating the Injuries to Garden and Field Crops, 
Pasture Lands, Timber Trees, and Grains, resulting from the 
attacks of destructive British Insects, exhibited by W. S. M. 
D’Urban and the Misses E. A. and G. Ormerod,” was recently 
exhibited at the Exeter meeting of the Bath and West of England 
Agricultural Society. This has been established through the 
labours of Mr. W. 8. M. D’Urban and the Misses E. A. and G. 
Ormerod. It is somewhat after the type of the instructive 
but incomplete collection in the Bethnal Green Museum; the 
arrangement, however, is different, for here the more natural 
grouping of the insects injurious to certain allied plants, crops, 
or productions is followed, entomological classification being 
altogether ignored. The collection is intended to be thoroughly 
practical in its teaching, and is well illustrated with specimens of 
insect ravages, or, where these are difficult of preservation, by 
beautiful models or illustrative vignettes. Although only com- 
menced last autumn it is already well spoken of, but help is 
asked for its future development; this, doubtless, will be forth- 
coming, and when located in its permanent resting-place of 
the Devon and Exeter Albert Memorial Museum it will form 
a fitting type of what ought to be in every local museum in 
the kingdom. Bethnal Green is dormant, possibly Exeter will 
outrun it.—H. A. F. 
EnromotoaicaL Prns.—We have received a sample-card of 
the entomological pins, gilt and plain, made by Messrs. D. and F. 
Tayler and Co., of Birmingham. We have pleasure in bringing 
them under the notice of our readers, although the well-known 
excellence of these pins is a sufficient recommendation.— Ep.
