Exhibitions. 
BIoNOMICS OF CIMEX HIRUNDINIS.—Mr. A. Bacor exhibited 
living specimens of Cimex hirundinis and stated that of a 
small number of specimens of this bug taken from a deserted 
house-martin’s nest in October a male and female were kept 
in a gauze-covered box and given opportunities of feeding 
upon human blood. They fed sparingly, but as they showed 
no signs of breeding they were then placed in a cool room at 
10° C. and subsequently transferred to a cold room at about 
0° C. After a month they were brought to room temperature, 
and then kept at 28° C. and afforded opportunities of feeding 
on man. They fed more vigorously than hitherto, and were 
observed to pair frequently. The female increased consider- 
ably in bulk as though developing ova, but no eggs were laid. 
The insects were then given the chance of feeding on a pigeon, 
and were observed to take blood two or three times, while 
they also continued to feed on human blood as well. A few 
fertile eggs were laid, and the young bugs which hatched in 
due course accepted human blood, but had not fed on the 
pigeon. One of the young bugs had moulted.
