severe inflammation by its puncturing. Dr. E.S. Hull, of Alton, Ill., was once, as he 
tells us, bitten in three places in the arm by one of these eroabuves, and the arm 
became so inflamed in consequence that for three days afterwards he almost lost the 
use of it. In the northerly parts of the United States, so far as we are aware, it 
does not occur. Like many of its allies it passes the winter in the perfect state, for 
we have ourselves captured it in south [llinois under loose bark in November, in 
company with its pupa (fig. 93, bd). 
Fia. 93.— Conorhinus sanguisuga: a, pupa; b, adult (from Amer. Entom.). 
All the species of this genus, most of which are South American, fly into houses by 
night, according to Burmeister, and live upon the blood of mammals, the puncture 
ot their beaks causing great pain. In the larval and pupal states they probably 
suck the juices of insects; for being wingless in those states they would have no 
means of reaching the larger animals. The single pupa that we found under bark 
in winter time occurred in a place that was about half a mile from the nearest house; 
so that at all events it certainly could have had no chance there to suck human 
blood. 
SUBORDER PARASITA. 
This group includes the suctorial lice, confined to mammals; they are 
strictly parasitic insects, being confined to their hosts constantly and 
deriving all their nourishment from them. They are wingless, and the 
mouth parts consist of a tubular suctorial organ. 
This suborder contains but two families, the first of which, the Poly- 
ctenidz, contains, so far as known, but two species, both of ahr are 
confined to bats, one in Jamaica and the other in China. These do not 
properly fall within the province of this paper, and it will not be neces- 
sary to give them further consideration. 
Family PE DICULID A. 
(The Suctorial Lice.) 
This family includes nearly all the species of the suborder and all 
that come within the limits of this paper. 
We need only add to the character above given the short rostrum 
without joint and the tarsi adapted to clasping and holding to hairs.
