GIRAUL T— THE BEDnUC

July. Another; full-fed in instar V, but starved after the final molt on .\ugust 
the 3rd, died on September 13th after living forty-one ( 4.1 ) days. .\t Blacks- 
burg, Virginia, in 1902 an adult confined in an ordinary pill-bo-v, as in the fore- 
going, and kept in a cool room in a laboratory, live seventy-five ( 7 5 ) days 
without food, from August to November. Here, low, fall temperatures doubtless 
lengthened its life. 
U’ith food, a single { i ) fertile female lived in confinement eighty-one (81 ) 
days, from June to September; it was captured in an an infested bed, and had 
evidently been adult for several weeks prior to capture, .\nother, reared in con- 
finement, lived as adult with food, from ,\ugust iith to October 8th, or fifty- 
nine (59) days. 
At Blacksburg, Virginia, an adult confined as usual, and fed once at the end 
of the first thirty (30) days, and from thence unfed, lived two hundred and fifty- 
nine ( 259 )days or about eight and a half months. This was from .\ugust, 1902, 
to May, 1903. Low temperatures, again, doubtless account for this great increase 
in length of life. The insect was numb for a greater part of the time, and 
several weeks before its death declined food, apparently unable to take it. ( C’f. 
DeOeer, 1773, pp. 304-305). 
From these records, though meagre, and from other considerations, the 
writer cannot help thinking that this insect lives normally but a single season as 
adult, or that it is single brooded in habit. Professor Herbert Osborn, in a 
letter, informs me that this is also his belief.^ The important fact apparently 
indicated, is that the activly reeproducing males and females survive but the 
actual breeding season and do not live over the following season, at least to 
continue reproduction. These of course, are but suggestions, and cannot be at 
pre.sent fully substantiated. 
3. Feeding habits in confinement; general notes. 
Nothing of importance was noted in regard to feeding habits, e.xcept- 
ing perhaps that females when once full-fed, were unable or unwilling to feed 
again within thirty-si.v (36) hours, or longer. 
As very many definite statements have not been published concerning the 
general habits of the bedbug, a few notes in this respect may not be amiss in this 
connection. The writer had some very unpleasant experiences with these 
a. January 30th. 1905. Olliers have also stated this (Lugger. 1896) though giving no data upon which it is 
based.
