than ever inclined to doubt the distinctness of some of the 
others. Some readjustment of names will eventually be necessary. 
1. Pseudolynchia brunnea (Latreille.) 
Specimens at the United States National Museum: 
Ames, Iowa, without host; two specimens, which F. Knab 
(1916, Insecutor Inscitise Menstr., IV, p. 3) referred to P. maura. 
St. Vincent Island, Florida, off Antrostomus carolinensis 
(Gmelin) (W. L. McAtee Coll.) 
Princeton, Florida, off Antrostomus vociferus (Wilson) (W. 
Byrd Coll.) 
Barro Colorado, Gatun Lake, Panama, off a nighthawk, 
Chordeiles acutipennis (Boddaert), September 24, 1923 (R. C. 
Shannon Coll.) 
Specimens at the American Museum of Natural History: 
Sherborn, Massachusetts, off Antrostomus vociferus (Wilson) 
(C. W. Johnson Coll.) 
St. Augustine, Florida, off chuck-will’s-widow, Antrostomus 
carolinensis (Gmelin) (C. W. Johnson Coll.) 
Specimens received from the Entomological Branch of the 
Department of Agriculture of Canada (through Mr. C. H. 
Curran) : 
Low Bhsh, Lake Abitibi, Ontario, off a nighthawk, Chordeiles 
virginianus (Gmelin), four specimens (N. K. Bigelow Coll.) 
2. Pseudolynchia maura (Bigot.) 
A study of an extensive series from all parts of the world has 
now convinced me of the utter futility of separating lividicolor 
from maura, even as a variety. One finds all transitions between 
pale-colored and dark specimens. Moreover, I am inclined to 
believe that P. maura was originally an Old World insect, which 
was introduced by man into the Americas, together with the 
domestic pigeon. 
Unless otherwise stated, the host of the specimens recorded 
below is in each case the domestic pigeon.
