Habitat, Westmoreland County, Pennsylvania, with Am- 

 plyopone ■palli^es. 



This insect represents the genus Amaitrofs of Europe, dif- 

 fering in the absence of the abdominal margin, and is related 

 to some of the Japanese Batrisi {longicornis^ Sharp, and soli- 

 tar ins, 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, Pennsj'lvania, 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.
