82 NATURAL History BULLETIN. 
Habitat, Westmoreland County, Pennsylvania, with Am- 
plyopone pallipes. 
This insect represents the genus Amaurops of Europe, dif- 
fering in the absence of the abdominal margin, and is related 
to some of the Japanese Latrisz (/ongicornis, Sharp, and solz- 
tarius, Sharp) from which it differs in the absence of eyes 
and the extreme length of the fourth dorsal segment. For 
the loan of this interesting species we are indebted to Mr. P. 
Jerome Schmitt, of St. Vincent College, Pennsylvania, to 
whom is also due the honor of its discovery. The specimen 
was received after the rest of the monograph was in press, so 
we were unable to insert this description in its proper place.
