634 General Notes. [June, 
in the life-history of Cossus centerensis Lintner,” containi 
excellent biological matter, and illustrated by two well-engraved 
plates. The publication of this Bulletin marks a new era in the 
work and development of the entomological division of the agri- 
cultural department, and we hope the publication will be well sus- 
tained. Psyche, vol. 1, Sept.—Oct., 1882 (issued late in 1883) 
contains a noteworthy paper by Dr. Geo. Dimmock, on some glands 
which open externally on insects. Vol. Iv, Nos, II 5-116 contains 
Mr. Lintner’s “ New sexual character in the pupæ of some lepidop- 
tera ;” a very just tribute to the memory of J. L. LeConte, by C. V. 
Riley; the gills of insect larvae, by G. McCloskie; the screw- 
worm-fly (Compsomyia macellaria), by S. W. Williston —The 
oldest Tracheates known are probably two fossil myriopods from 
the Lower Old Red Sandstone (Devonian) of Scotland, described 
. by B. N. Peach in Proceedings Royal Physical Society of Edit 
burgh, 1881.82. 
ZOOLOGY. 
OCCURRENCE OF CHLOROPHYLL IN Animats.—C, A. wag 
bases his conclusions as to the identity of animal and vegetable ei 
rophyll on the fact that the wave-lengths of centers of the (a 
the same solutions of animal and vegetable chlorophyll ate ‘is 
same, and that the wave-lengths of the centers of the | ik 
the same when the same reagent isadded tothe resperir ae E 
Without committing himself to accepting the views ol ae 
Sorby, he applies the term chlorophyll to that ss mor 
or mixture of coloring matters, which can be extrac ohol, of 
? 
green leaves, such as those of Primula, by means of e A 
alcohol and ether. The coloring matter, to which the w 
given the name “ enterochlorophyll,” and which can to 
from the liver or other appendage of the enteron of the 
was shown to be probably produced by, and in, ve a alge 
animal, and not food chlorophyll. The absence o ee old entero 
in sections of the livers of certain mollusks veo" ue to their 
chlorophyll, shows that this pigment ere ton’s observe
