2. Adult. An adult, not recently fed when captured on September iith, 
was placed under the bell-jar at 9:26 A. M. The body of the mouse was then 
cold, and a little stiff. 
The adult wandered about, and then at 9:27:30, crawled under the carcass; 
body then flat and fully colored. Hiding from light. In a few minutes, crawls 
from beneath the carcass to the side of the bell jar, not having fed. Jar covered 
with a black cloth 
At 9:44. M., jar uncovered and the adult found fully gorged with the 
blood from the carcass. It was found at rest on the back of the mouse, but 
began to wander on exposure to the light. Body of mouse now stiff and cold. 
.\dult removed. 
■Vnother hungry adult placed under the bell-jar at 1 1 A. M., the mouse then 
being dead 2 hours and 20 minutes. It was pale, having just recently passed the 
fifth ecdysis. .-Xt once hid under the carcass. 
It did not feed up to 3 P. M., and was then removed. The blood in the car-

lack of material. 
B. E.xperiment with a Ih'ing viouse. 
A mouse trajrped in the insectary of the Department of Agiculture during 
the night of September 21-22, 1905, was confined under a bell-jar as in the first 
experiment at 9 A. M., September 22nd. 
,\t 9:40 A. M., three adults, captured when full-fed in instar V, on September 
iith, and since molting on September the i8th, and a single larva in instar IV, 
hungry when captured, were placed under the jar and the latter covered with a 
black cloth to exclude the light. None of the insects had fed up to 6 P. M. 
At 7 A. M., September the 23rd, the day following, the cloth was removed 
from the jar, and all of the insects found fully gorged with blood, the abdomens 
of the adults immensely swollen. Plpon exposure to the light they as usual 
wandered quickly about. The experiment was not repeated because of the lack 
of enough suitable material, — hungry bedbugs. 
C. Experifneut with recently born mice. 
At 6.30 P. M., September 28th, three recently born mice were placed in a 
group on a clean sheet of white paper and covered with a small bell-jar. 
.'Uthough much alive, their bodies were cold. 
Immediately afterwards, three adults of lectulariiis, full-fed nymphs in instar 
V when obtained on September iith, molting on September 19th, and now, 
therefore, hungry adults, were introduced. Left over night in a dark room.
