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.

body, thickly haired, dark brown, of 14 segments, fifth with 
stems having a length one and one-half and two and one-half

nearly to distal enlargement and dorsal loops of distal circum- 
filum extending to apex of basal enlargement of next segment.
