THE NORTH AMERICAN SPECIES OF NEMOBIUS. 
By Samuel H. Scudder. 
The North American species of the Orthopteran genus Nemobius 
Serville are more numerous than has been supposed, notwithstanding 
that several species have been more than once described as distinct. 
Prof. L. Bruner, of Lincoln, Neb., has kindly sent me a considerable 
series from his collection; Mr. A. P. Morse, of Wellesley, Mass., has 
placed his collection, mainly from New England, in my hands ; the 
collections of the Museum of Comparative Zoology and of Mr. S. Hen- 
shaw have been at hand; and these, with a few specimens from the Na¬ 
tional Museum, added to my own, form the basis of the following ta¬ 
ble and descriptions. Although Trinidad belongs zoologically to South 
America, I have added one species found there. The number of 
known species is hereby doubled, and doubtless more await discovery. 
I should add that “ Nemobius circumcincfus ” Scudd. (Proc. Bost. 
Soc. Nat. Hist., XII, 143) from Mexico is a Prothacustes and iden¬ 
tical with the later described P. mexicana Sauss.; the species given by 
Provancher (Faune Ent. Can., II, 24) as “ Nemobius ( Anaxipha) 
septentrionalis Scudd.” was named for him by me as Anaxipha septen- 
trionahs, but it is identical with Anaxipha exigua (Say); it was for¬ 
merly (Nat. Canad., VIII, 61) called by him Nemobius exiguus, as 
Says species; an insect referred to as (t Nemobius marginata ” by 
Miss Murtfeldt (Ins. Life, V, 155) is probably an accidental error, as 
no such name has been given ; li Nemobius? pulicarius ” Walk. (Cat. 
Derm. Salt. Brit. Mus., I, in), is an Anaxipha. This covers all the 
North American species referred to Nemobius , except those given be¬ 
low in the synonymy. 
I have followed Saussure in employing the female alone (or almost 
.alone) in constructing the following table, since the males of several of
