recording trilineata from Dakota, British Columbia, California, 
Nebraska, Canada, and the region of the Mackenzie River, and 
stated that trilineata differs from undata “in being larger and 
more robust and blunt anteriorly, the head entirety black and 
more coarsely punctate, the venter more widely black, and the 
femora much more invaded with black.” Forty-five years have 
elapsed since Uhler published these notes, yet no one has given 
us any further information regarding Kirby’s species. 
Among some Hemiptera collected in northern Michigan by 
Mr. S. Moore of Detroit, recently submitted to me by the 
Museum of Zoology of the University of Michigan, there is one 
Specimen which I refer without hesitation to Neottiglossa trili- 
neata. It agrees well with Kirby’s original description, differing 
only in its slightly smaller size (53/2 mm. as compared with 3 
lines) and in the markings of pronotum and scutellum; but these 
differences are no greater than may be found in a series of N. 
undata. The specimen before me differs more considerably from 
Kirby’s figures, but these agree neither with each other nor 
with his description, for in one figure the lateral margins of the 
pronotum are represented as concavely sinuate, and in the other 
as straight and concolorous, while the description reads “Pro- 
thorax. .with the lateral margin, .white.” 
Neottiglossa trilineata, as I identify it, differs from N. undata 
in its darker coloration anteriorly, in the more obtuse apex of 
the head, in the more broadly flattened pronotal margins, in 
antennal structure, and in the form of the ventral abdominal 
segments. Since the species has been so little understood by 
American entomologists, I have thought best to give a full des- 
cription of the specimen before me, together with figures illus- 
trating some of the characters by which it differs from N. undata- 
Head, black, a little bronzed, somewhat shining, deeply 
and closely punctate, the punctures somewhat finer on the base 
of the vertex. Sides of head subparallel for a short distance 
before the eyes, thence concavely sinuate to a point beyond the 
middle of the tylus, thence straight and converging at an angle of 
about 110°; extreme lateral margin very lightly reflexed; apex
