Though there is considerable difference in the drawings, this is prob- 
ably the same species as 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 sp.) 
Three species of lice are found upon monkeys, all being generically 
distinct from those infesting other animals. They form the genus Pedi- 
cinus, the most essential character 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, and radiatus, according 
to Piaget, and Macacus sinicus, according to Giebel; Pedicinus longiceps 
Piaget, occurring according to its author upon the Jlacacus cynomolgus 
and the Semnopithecus pruinosus ; the Pedicinus br aka Piaget, infest- 
ing the Cercopithecus monas. 
Aside from these species of Pedicinus, Gervais describes a species of 
Hematopinus, H. obtusus, from the Semnopithecus maurus. 
The abundance of these vermin upon monkeys can be attested by all 
visitors of zodlogical gardens or menageries, and the ready means 
adopted by the hosts for their subjugation are equally familiar—a 
method of destruction which, by the way, is said to be adopted by many 
tribes of inferior races belonging to the human species. 
THE SUCKING DOG-LOUSE. 
(Hematopinus piliferus Burmeister.) 
Although the dog has been the closest companion of man among the 
domestic animals from very early times, and consequently this parasite 
in all probability well known to keepers of dogs, it was not technically 
described until about the year 1838. 
It does not appear to have been a very numerous or injurious para- 
site, apparently much less so than the Trichodectes 
latus infesting the same animal, and less annoying 
than either ticks or fleas. Denny says (Monog. Anop. 
Brit., p. 29), ““I have found it upon dogs two or 
three times, but it is by no means of common occur- 
rence.” We have examined many dogs in quest of 
it, but only a single specimen so far has been our re- 
ward. Denny says (loc. cit.), “I also received 
specimens from the ferret.’ It can hardly be in- 
ferred, however, that this animal is consequently a 
normal host for the species, as such an instance 
might occur entirely from accident, the louse having 
been transferred from some dog to a ferret asso- Fic. 5.—Hematopinus 
ciated with it. piliferus. (Original.)
