cases wliere it is necessary to examine the neuration of the wings, 
the left elytron may ho raised, and the wing expanded without any 
damage to the specimen. For very small and delicate insects it is 
necessary to use the varnished-steel or silver-wire pins, prepared es- 
pecially for micro-insects, fixing them in a small block of pith impaled 
on a strong pin ; and in order to insure a successful preparation of 
certain very fragile species, such as Typhlocybidae, and some of the 
smaller Delphacidse and Deltocephali, especially if they are not 
quite mature, it is sometimes desirable to expose them to the action 
of the atmosphere for a few hours, to give them the opportunity of 
parting with some of their superfluous moisture before attempting 
to pin them. For pinning the larger species, I strongly recom- 
mend the finer sizes of black Vienna pins, cut down to the length 
of an English No. 8, and run through the specimen for two-thirds 
of their length. English black pins are both clumsy and brittle. 
The preservation of one’s collection is of the first importance, and 
fortunately is, with ordinary care, easily accomplished. Our three 
great enemies are, — verdigris, mould, and mites. By using the pins 
above mentioned we obviate the first of the.se ; and by keeping our 
store-boxes well supplied with camphor, the two latter may be 
elfectually prevented. The identification of the species is not an 
easy matter at the present time, but English descriptions of most 
of our species are to be found scattered through the pages of several 
volumes of the ‘ Entomologist’s Monthly ^Magazine.’ 
The foregoing remarks apply solely to the Ilomoptera. The 
Ileteroptora should be carded, and their identification is rendered 
comparatively easy by Mr. Saunders’ excellent ‘ Synopsis.’
