2. Cimex pilosellus Horv. 
Clinocoris pilosellus Horv. Ent. Monthl. Mag. (2) XXL p. 12. fig. (1910). 
This species is a parasite of bats, but is easily distinguished from 
-the European Bat-bug ( Cimex pipistrelli Jen.) by the lateral sides of 
the pronotum widely dilated. It is more closely allied to the Common 
Bed-bug, but differing by the characters given in the key above. 
I have described, this species originally from Okanagan Landing, 
British Columbia, where it was caught on Myolis longicrus ; but it also 
inhabits the United States and feeds on various species of bats. The 
specimens of the U. S. National Museum of Washington examined by 
me were found at the following localities : Lewis Co., N. Y., on Vespe¬ 
rugo noctivagus ; Bowmans Bluff, N. C., on Nycticejus crepuscularius ; 
Kernville, Cal., on Vesperugo hesperus (A. K. Fisher); Willcox, Ariz., 
on Antrozous sp. (A. K. Fisher).

Mus. II. p. 153. tab. 13. fig. 1, 2, 5. (1908). 
A widely distributed species in the tropical regions of Africa and 
Asia, but also occurring in the West Indies and Brazil, where it was 
most probably introduced from Africa. The Hungarian National Museum 
possess specimens from Brazil (S. Paolo, Manaos), Trinidad (Port of 
Spain) and Jamaica (St. Ann’s Bay). I have seen in the Brussels Museum 
a specimen from Antigua determined by Lethierry as C. foedus Stal. 
Cimex hemipterus is a parasite of man and occurs in human 
habitations, but sometimes feeds on birds and bats. A part of the spe¬ 
cimens I have received by the kindness of the Hon. N. C. Rothschild 
from St. Ann’s Bay, Jamaica, have been collected on poultry and in 
poultry houses. Capt. W. S. Patton has had a number of specimens 
taken in India from the bat Scotophilus Kuhli and — according to
