960 PEOCEEDINGS OF THE THIRD ENTOMOLOGICAL MEETING 



in Italian, the only exceptions being in the cases of very well-known 

 names of erroneous spelling {e.g., Lucknow, 'Calcutta). Thus, it is 

 preferable to write Darjiling, Karachi, Muzaffarpur, rather than 

 Darjeeling, Kurrachee, Mozufferpore. 



Vague indications, such as " on cotton " should be avoided, as such 

 labels give no real information. Full particulars (e.gr., " imago eating 

 cotton flowers," " imago resting on cotton leaf," " larva rolling and 

 eating cotton leaf '") give definite information and are j)roferable. The 

 correct botanical names of foodplants should also be ascertained and 

 used as far as possible, as popular or local names are often incapable 

 of exact identification. 



Dry, unpinned material. Some specimens are best collected and 

 kept dry and unpinned and may either be preserved permanently in 

 this state or be Tdf>rot\ aud set at any subsequent time. 



Such insects va butterflies, dragon-flies, ant-lions, and, generally 

 speaking, any broad-winged insects, may be j^laced inside paper enve- 

 lopes with their wings folded over their backs and in this way a large 

 number can be packed in a comparatively small space. Envelopes 

 are best made of a moderately thin slightly glazed paper, rectangular 

 pieces rather longer than broad being folded over to form a triangular 

 envelope, on the outside flaj) of which should be written full data (place 

 and date of capture, collector's name, and any remarks). (Plate 156, 

 fig. 3.) These envelopes can be stowed in any tight box, together 

 with some powdered naphthaline, and may be kept for years if 

 required. Special boxes for storing such envelopes, and useful either 

 in the case of a c"li'"'''i"n kei^t in papers or of duplicates kept for 

 exchange or pres' •■^fai'iv, have been designed and desciibed by Mr. E. 

 Ernest Green, w ose account of them is as follows : — 



" Triangular paper envolnpes have been employed by travelling 

 entomologists for the temporary storage of butterflies, for many years. 

 But it has been usual to lay these envelopes haphazard in plain boxes, 

 in such a manner that it is impossible to find any particular specimen 

 without turning over the whole contents of the box. 



'• By the use of the special boxes here described the envelopes occupy 

 very much less space, the contents ore less liable to damage, and any 

 individual specimen can be found and removed with the greatest ease 

 without disturbing the remainder. 



'' The boxes are made of tin plate, with partitions dividing them 

 into trough-shaped spaces. The envelopes rest edgeways in the troughs. 



The boxes are fitted with two lids, above and below — 



" Plate 157, fig. 1, shows a box with the upper lid removed and 

 the iower one in place. The box measures 9 in. by 6 in. by 3 inches.
