EDWARD burgess's WORK IN NATURAL SCIENCE. 



Mr. Samuel H. Seudder, in the Proceedings of the Boston Society of 

 Natural History (volume xxv, pp. 358-;3G4), gives an appreciative ac- 

 count of the work which the late Edward Burgess did in natural his- 

 tory. Mr. Burgess was associated with Mr. Scudder in the early part 

 of his work in entomology, and one of his first contributions was pub- 

 lished conjointly with Mr. Scudder. Although a close student of the 

 Diptera, Mr. Scudder shows that Mr. Burgess's best work was done in 

 insect anatomy, and that, although familiar with many species of two-

 young larva and opening on inside of pod by which it has entered— enlarged; d, d, d, eggs— natural 

 size; e, first larva— greatly enlarged;/, postembryonic leg; g, prothoracic spinous processes— still 

 more enlarged (original). 



winged flies, he never described but four new species. His work upon 

 the anatomy of the Psocidae, and particularly that upon the Milkweed 

 Butterfly, are justly cited as models. The same may be said of the work 

 which he did for us, in connection with Dr. C. S. Minot, on the anat- 

 omy of the Cotton Worm. When Mr. Burgess left entomology for the 

 designing of yachts the former science lost one of its ablest American 

 students, but the world at large undoubtedly derived more immediate 

 benefit from his labors in the latter direction. 



SWARMING or THE ARCHIPPUS BUTTERFLY. 



The swarming in the spring and fall of this large cosmopolitan but- 

 terfly has been frequently noticed and often discussed in entomological 

 periodicals. It migrates to the north in the spring and to the south in
