pean species and another, Diplosis pini-rnaritimcs , and the 

 American Diplosis pini-inopis Osten Sack en (which that author 

 says may be the same as D. pijii), pupate out upon the needles 

 in a resinous cocoon. The Montery Pine fly never pupates out 

 upon the needles and its cocoon is made of the fibres and is 

 spun by the insect. 



Diplosis brachyntera of Europe has upon the back of its 

 larva ' ' Dornwarzchen ' ' or thorn papillae. The larva live be- 

 tween the needles which are stunted but not swollen at their 

 base, and pupation takes place in the ground. In these points 

 it differs from the present insect. 



Diplosis brachyntej'oides O. S. is described only from the 

 deformations produced by the larvae which, though on the east- 

 ern scrub pine, are similar to those on the Monterey Pine, 

 except that the needles strongly diverge, which they are not 

 caused to do in the present case. To his rather inadequate 

 description Osten Sacken adds the supposition that the larvae 

 pupate in the ground, since he saw some individuals caught in. 

 a spiders' web apparently as they journeyed toward the ground. 



The European Diplosis signata is distinctly different from 

 our species, and it will be sufficient to say that the antennae of 

 the male are composed of alternate single and double joints. 



Dr. Packard's description of his Diplosi pini-rigidcc from the 

 pitch pine of the Northeastern States is drawn very vaguely, 

 but it undoubtedly strongly resembles the present species. The 

 chief differences are apparently as follows : In Packard's 

 .species the larvae lie between the two inner needles of the 

 whirl while the third or outer needle is frequently not swollen. 

 The larvae ascend to the terminal buds before pupation and 

 there construct a cocoon of the pitch which exudes from 

 the.se buds, ' ' His statement that there are two broods may be 

 disputed, I believe. In his description he has mistaken the 



origin of the third vein for the cross vein." — (Snow.)

 Mr, H. K. Burrison will go to the Yellowstone Park this .Siimtner to 

 collect. He states that he was compelled to pay duty recently on some 

 btitternies and the New York Custom House classified them as "a non- 

 enumerated manufactured article" and asked twenty per cent duty but 

 finally accepted ten per cent.
