VbZ PROCEEDINGS OF THE THIED ENTOMOLOGICAL MEETING 



Or the envelopes may be packed in stout paper packets as described 

 by Major H. D. Peile in tbe Journal of the Bombay Natural History 

 Society, Vol. XXV, pp. 309-312 (September 1917), as follows :— 



" Standard sizes of paper-triangles should be used. For small and 

 medium-sized butterflies semi-transparent butter-paper is best, as it 

 enables the contents to be seen through the paper at a glance, and 

 guards against spread of any grease that may form. For large triangles 

 use stronger glazed paper such as that of English illustrated weeklies, 

 as glazed paper does not rub the scales ofi the wings. 



" Place the newly-captured butterfly with the antennae close against 

 the forewings and at the fold of the paper, so that they dry in that 

 position safe from injury (see sketch 3). Do not place it with body 

 against the fold [see sketch 4) as in this position the antermse almost 

 always dry sticking out and eventually get broken off in handling the 

 paper or specimens. 



" If papered butterflies be massed together in a box any particular 

 specimen cannot be got at without many being handled, resulting in 

 damage to some sooner or later. 



" The paper triangles should be kept in packets of corresponding 

 standard sizes, so that these packets, fitting closely in an ordinary biscuit- 

 tin, economize space and enable any one packet to be easily taken out 

 without disturbing its contents. 



" The paper triangles should be so placed in a packet that the bodies 

 of the specimens are alternately to right and left and so lie evenly ; 

 if not so placed they form a lopsided pile, and space is wasted and 

 pressure is all on one side. 



" All packets should be of uniform height — 1 inch — so forming 

 two or three tiers in the tin according to the kind of biscuit-tin used 

 and each packet should contain just so many specimens as not to be 

 loose in it, and then the vertical sides of the packets take any weight 

 or pressure. 



" A medium-sized packet has its longest side about 3^ inches ; larger 

 packets can be made double, or smaller ones half the size of this one. 

 Stout fiaper such as parchment-note answers best. 



" Attached is an outline pattern (reduced half-size) for making such 

 a packet (Plate 159, fig. 1). Cut along the outside continuous lines, 

 and fold backwards at the dotted lines. This pattern may be used 

 for outlining others with a pencil, keeping the centre portion of the 

 pattern fixed with the fingers of the left hand, and turning up each 

 portion after outlining as one works inwards. Paste A to underside 

 of B so that C is between the two ; then paste underside of D onto E 

 with F between them. To close the packet insert the flap between
