Eurychilopterella brunneata Knight 
Eurychilopterella brunneata Knight (1927d, 
p. 141). 
This species is distinguished from luridula 
Reuter by its uniformly fuscous-brown col- 
oration, longer head and larger size. 
Mate.—Length 4.70, width 2.10. Head 
width 0.86, vertex 0.38, head length 0.71, ex- 
tending 0.44 beyond front of eyes; hori- 
zontal, flattened beneath; gula slightly sul- 
cate; lower margins of eyes extending slight- 
ly below gula. Rostrum, length 3.20, reach- 
ing to base of genital segment. Antennae, 
first segment, length 0.29, more slender on 
basal half; second, 1.26, cylindrical, equal 
to thickness of first segment; third, 0.44; 
fourth, 0.36; last two segments slender. 
Pronotum, length 1.18, width at base 1.77; 
disk more distinctly flattened than in luridu- 
la, coarsely and closely punctate; calli con- 
fluent, smooth, smaller than in Juridula.

Hesperophylum Reuter 
Hesperophylum heidemanni Reuter 
gas hae heidemanni Reuter (19124, 
pela): 
This is a rare species, yet widely distrib- 
uted as indicated by the few records. Orig- 
inally described from a New Hampshire 
specimen, it was later taken at Washington, 
D. C. (Heidemann). H..G. Barber (1914, 
p. 170) recorded it from Arizona. The 
most recent record is a female specimen, 
taken June 26, 1931, in Ames, Iowa (H. 
H. Knight) ; it was collected while sweep- 
ing under trees. This species has not been 
found in Illinois, but doubtless it will be 
eventually. The male is unknown. 
In previous books this genus has frequent- 
ly been considered in a separate family, the 
Termatophylidae.
