The habits of common, cosmopolitan species such as the American, 
oriental, German, and brown-banded cockroaches are so well known 
that we shall not expound them here, except to emphasize their rela- 
tion to the dissemination of infectious agents. General information 
on the habits of cockroaches can be found in any current entomo- 
logical textbook, in Mallis (1954), in Gould and Deay (1940), and 
in U.S.D.A. leaflet No. 144 (1950). Rehn (1945) gives an excellent 
account of the mechanism and extent of the world-wide dispersal of 
11 domiciliary cockroaches, “man’s uninvited fellow travelers.” 
Very little biological information has been recorded for most of 
the species listed above or for unlisted domiciliary species that are 
much less well known and which have not yet been implicated in 
transmission of disease agents. With the exception of Blaberus 
atropos and Blaberus fuscus, whose habits are unknown to us, the 
species listed are all domiciliary to some degree; evidence for this 
statement is given below. 
Blaberus cranufer. This species is a household pest in Cuba 
(Deschapelles, 1939). 
Blaberus discoidalis, This species is found in Ecuador in eating 
places as well as in patios and gardens (Campos, 1926). In Puerto 
Rico it may be found with Leucophaea maderae in fruit debris in 
stores (Wolcott, 1950) or in homes where, however, it is never abun- 
dant (Sein, 1923). Occasionally this species is introduced with 
tropical plants and it may become temporarily established in green- 
houses in the United States (Hebard, 1917). 
Eurycotis floridana. This species has been recorded from Georgia, 
Florida, and Mississippi, where it is found outdoors in sheltered areas 
such as stumps, under signs, and bark of dead trees (Hebard, 1917). 
Occasionally it enters houses (Creighton, 1954; Roth and Willis, 
1954).
