could be reared in an agar medium, and, if so, to determine conditions 
necessary for their normal growth and development. "A series of newly 
hatched larvae were placed in vials containing jelled agar 50 per cent 
and green apple juice 50 per cent. Another lot was placed in vials con- 
taining jelled agar alone, covered with a thin apple skin. In all cases 
the larvae penetrated the agar and lived for a pericd of time. Mortality 
was high but a few of the larvae are still alive and will probably pupate." 
D. E. Fink, who is engaged in a study of the anaerobic metabolism 
of insects at the Takoma Park Laboratory, reports the installation of a 
new device "which," he says, "makes the water bath suitable for experi— 
mental work in a room whose temperature is considerably above that de— 
sired for an experiment. The device depends upon the installation of a 
magnetic water valve in the system, controlled by a relay in such a manner 
that a spray of cold water automatically cools the bath and a heating unit 
acts in the opposite manner. So far as is known, this bath is the only 
type having this arrangement installed to work automatically, and elec- 
trically controlled." 
BEE CULTURE 
Professor C. R. Kellogg, Entomologist, Fukien Christian College, 
Foochow, China--now appointed Field Assistant at the Somerset Labora— 
tory—-brought with him from China some living bees of the species Apis 
indica Fab.. in order to study under American conditions the life histo— 
ry, growth, development, flight, wintering, nectar gathering, and polli- 
nation work of this Chinese bee. He also brought with him specimens of 
Apis florea Fab. and Apis dorsata Fab. from India, and Apis indica from 
India, Java, the Philippine Islands, and many parts of China. These are 
preserved in alcolol for anatomical and biometrical study. Starting 
June 14 with 27 queen bees of Apis indica taken fron native colonies in 
Foochow, he reached Washington July 20 with 7 living queens. Of these 7, 
35 survived and were introduced successfully into Italian colonies, and 
the first cycle of the Chinese brood is emerging. Apis indica differs 
in a number of respects from the bees commonly found in the United States 
and an effort will be made to carry them through the winter and if pos— 
sible secure increase in the number of colonies for the proposed general 
study of this race of bees. 
A. P. Sturtevant, in charge of the sublaboratory at Laramie, 
Wyo., reports the abnormal death of adult bees, including a large number 
of queens, in the vicinity of Casper, Wyo. Examination of these bees in- 
dicates a slight infestation of Nosema apis, but by no means enough to 
account for the death of so large a number of bees. 
In connection with pollen-gathering studies conducted at the 
Laramie, Wyo., station, Russell Smith has devised a pollen catcher
