SOME COCKROACHES FOUND AT BRADFORD. 
J. W. CARTER, 
Recorder of the Entomological Section, Bradford Naturalist’ and Microscopical Society, 
etc. 
A Few notes upon those ‘loathsome insects’ which have, from time 
to time, found their way into our workshops and our kitchens, and 
there found a congenial habitation, like some intrusive members of 
the mammalia, may be of interest ; and further, may induce others” : 
to give us the benefit of their experiences of these unwelcome guests. 
Periplaneta orientalis. This, perhaps the most hated of all our 
domestic pests, swarms not only in many houses, but also in 
workshops, etc., in company with other species of Cockroach. 
Its enormous numbers in some places are almost incredible.

Periplaneta americana, so far as I have been able to ascertain, 
is confined to workshops, particularly dye-houses, where in some 
cases it is found in great numbers 
des, M.C.S., gave me a few specimens of this species 
ao he had found in abundance in a Bradford restaurant. 
Last week I had sufficient brought me by Mr. W. Leggett, 
from a warp-sizing place, to fill a pint measure, mixed with — 
a goodly number of their peculiar egg-pouches!! In this — 
place there are thousands upon thousands of this species and 
£. orientalis, and formerly P. americana occurred with them, 
but somehow it seems to have disappeared, at all events it has 
not been seen lately. Can it be possible that the combined 
forces of the two smaller species, which have predominance in 
numbers, have driven out the bigger one? I think not; but 
am inclined to the opinion that the incessant war waged against — 
P. americana, as being the supposed parents of all the smaller 
ones, partially, if not wholly, accounts for their disappearance. 
Blaberus giganteus. About a year ago a very fine example of 
this monster, a native of the West Indies, and measuring. five 
inches across its expanded wings, was brought me from a place 
where imported logwood, and other foreign woods, are ground 
up. It is, as the name implies, a giant in appearance ; and no 
wonder that the captors of it were afraid to handle it. 
would be a detestable companion in any workshop.
