THE BRITISH NATURALIST. [August 



trees, these cases I have never found commonly, although in many 

 different localities. The Alders should now be examined, when some 

 of the leaves will appear as if partly eaten through, if on turning the 

 leaf over we find a small yellowish green larva under a few threads of 

 silk it would be the larva of Bucc. cidarella. In captivity these larva 

 spin their brown ribbed cocoons on the twigs of the food plant. In 

 looking for these larva we shall probably observe some of the leaves, 

 more partically the young terminal ones, have a faint brown line run- 

 ning along the side, crossing to the midrib, and giving the leaf a slight 

 distorted appearance this is caused by the larva of T. resplendella, they 

 afterwards form a blotch from mining a larger portion, out of which 

 they cut an oval case, fall to the ground and change to pupa. 



If the the leaves of the Hawthorn he now examined, some small 

 brown patches will be observed on many of them and gradually 

 getting larger, these are the mines of Cemiostoma scitella and the leaves 

 of the everlasting pea (Lathyrus sylvestvis) will be found blotched by 

 the larva of Ceni. lathyiifoUella. The dogwood (cornus sanguiniaj have 

 leaves at this time mined by the larva of A. Treitschkiella, from which 

 they cut out an oval case and drop to the ground, the imago appearing 

 the following June. The above are a few of the species that may be 

 take this month among many others so that it will be seen there is 

 still plenty to do.

Foreign Parcels by Sample Post. — -In the proceedings of the 

 Entomological Society for May, the Secretary stated that Lord 

 Walsingham had received a letter from Sir Arthur Blackwood, an- 

 nouncing that small parcels containing scientific specimens would not 

 in future be stopped by the English Post Office, when sent abroad at 

 sample post rates. 1 have, for several years past, sent parcels of 

 Lepidoptera to the United States by sample post, and they have 

 never been stopped. Some years ago a post-master here was good 

 enough to mark outside " Examined at Hartlepool Post Office, and 

 contains nothing of the nature of a letter," adding the official stamp. 

 These parcels were, of course, made up in his presence, and I expect
