168 INSECTS AFFECTING DOMESTIC ANIMALS. 
The eggs are deposited in folds of the clothing, and, according to the 
-estimates of Leeuwenhoek, a single adult female may have a progeny 
of 5,000 in eight weeks, and he adds that in the heat of summer this 
estimate might be very greatly exceeded. This will readily account 
for all the authentic reports of sudden and numerous appearances of 
this pest. 
A ready means of combating this pest is to thoroughly bake the 
clothing infested with it, or, to be fully as effectual with less heat, this 
might be accompanied by fumigation with sulphur or tobacco smoke. 
A repetition of this process two or three times at intervals of a few 
days, along with strict personal cleanliness, should overcome the most 
serious attack. ; 
Alt described, under the name of Pediculus tabescentium, the louse 
which he considered as the cause of phthiriasis, but later authorities 
consider this as simply the vestimenti present in aggravated numbers. 
Properly speaking, this affection should be termed pediculosis, and the 
term phthiriasis reserved for the attacks of Phthirius inguinalis. 
LOUSE OF THE APE. 
(Pediculus consobrinus Piaget.) 
Closely related to the human lice is a species described by Piaget 
occurring upon the Ateles ape (Ateles pentadactylus). It resembles 
especially the Pediculus capitis, but presents some differences in form of 
head and structure of abdominal appendages which have led this author 
to establish the separate species. It appears to differ less, in general 
appearance, from typical capitis than the varieties of capitis occurring 
on different races differ among themselves. 
Though there is considerable difference in the drawings, this is prob- 
ably the same species that is figured by Murray (Economic Entomology, 
p. 389) under the name of Pediculus quadrumanus and said to be taken 
from the Ateles ape. 
LicE INFESTING THE MONKEY. 
(Pedicinus spp. ) 
Three species of lice are found upon monkeys, all being generically 
distinct from those infesting other animals. They form the genus Pedt- 
cinus, the most essential BLO of which is the presence of but three 
joints in the antenne. 
The species are the Pedicinus eurygaster Gervais, which occurs upon 
the macaques, Macacus nemestrinus, cynomolgus, aud radiatus, accord- 
ing to Piaget, and Macacus sinicus, according to Giebel; the Pedicinus 
longiceps Piaget occurring, according to its author, upon the Macacus 
cynomolgus and the Semnopithecus pruinosus; and the Pedicinus breviceps 
Piaget infesting the Cercopithecus monas.
