A series of specimens was taken from a spider’s web on a 
leaf of Andropogon sorghum Linn. It is possible that this insect 
lives upon Andropogon, though it is very different from Con- 
tarinia sorghicola Coq., which is well known in America. It 
is described here because it is believed that the peculiar characters 
will make the recognition of this species easy and, therefore, no 
confusion need arise from a description not based in part upon 
a food-plant record. 
Bremia macrofilum sp. nov. 
Male.—Length, 1 millimeter. Antenne one-half longer than 
body, thickly haired, dark brown, of 14 segments, fifth with 
stems having a length one and one-half and two and one-half 
times their diameters, respectively. Basal enlargement sub- 
globose, distal enlargement oval, its length one and three-fourths 
times its diameter. Dorsal loops on basal circumfilum produced 
nearly to distal enlargement and dorsal loops of distal circum- 
filum extending to apex of basal enlargement of next segment. 
Terminal segment greatly produced, basal portion of stem with 
a length about five times its diameter, distal enlargement pyri- 
form, its basal third rather strongly constricted. Appendage
