1917] Osborn and Drake—Notes on Tingide 159 
outer boundary slightly more sinuate than in plexa. Wings 
slightly longer than abdomen. Abdomen quite broad in both 
male and female. Length, 4.6 mm.; width, 1.8 mm. 
Color.—General color brownish, slightly marked with yellowish 
and black. Antennz brownish, the distal half of apical segment 
blackish. 
Two specimens, a male and female from Urbana, Illinois. The 
photograph illustrates the type specimen; all specimens of Physa- 
tocheila are equally enlarged. This species is readily separated from 
allied forms by its larger size and the second segment of the antenne. 
Melanorhopola duryi Osborn & Drake (Plate VIII, Fig. e). 
The form of this species 1 
is not very broad when 
compared with females of 
other species in the genus. 
The third antennal segment 
is slightly enlarged towards 
the apex and the distal 
segment is decidedly conical 
rather than fusiform as 
stated by Parshley in his 
second paper. The photo- 
graph of the type will 
illustrate the structures 
mentioned. All _ photo- 
graphs of the species in this 
genus are of the same mag- 
nification and the antennze 
have been placed in a hori- 
zontal position with the 
body so that the propor- 
tions between the same or 
different species are quite 
accurate.
