Habitat. — The types, cf and 9 , come from Carcarana, x'\rgentina. 

 A number of other specimens were taken at the same place. It was 

 also attracted to lights at Rosario, about thirty miles east of Car- 

 carafia. 



This insect very likely is aquatic, as is the species aqiiaticiis, de- 

 scribed on a preceding page in the present paper.

Habitat. — Specimens of what are determined as this species are at 

 hand from the following localities: Los Indios, Isle of Pines, W. Ind., 

 I 9 , taken during 1912 by G. Link; Don Diego (100 ft.) Dept. 

 IVIagdalena, Colombia, S. A. (H. H. Smith) i 9 ; a single cf from 

 Piedra Blanca, Brazil, in April (H. H. Smith); i cf , 3 9 9, Puerto 

 Suarez, Bolivia, 150 M., i cT, Santa Cruz de la Sierra, Bolivia, 450 M. 

 and I cf and 2 9 9 Province del Sara, Bolivia, 350 M. (J. Steinbach). 

 One of these latter was taken in December, 191 2. 



The above localities would indicate a fairly extended distribution 

 for the species in South America as well as for North America as shown 

 in Hebard's paper referred to above. The specimens examined in the 

 series now at hand also show considerable variation in size and some 

 little in structure as well. 



31. Nemobius sp.? 



There is a single male specimen before me from Chapada, Brazil, 

 which appears to be distinct from N. ctibensis, but I hesitate to refer 

 to it as a distinct species with a separate name. Like two or three 

 other specimens of Nemobius referred to in the present report this 

 individual lacks hind wings, hence may not be typical of the species 

 to which it belongs. It was collected during July by H. H. Smith. 



32. Nemobius chapadensis sp. nov. 



A very dark-colored rather small-sized and slender insect, in which 

 the distoventral spurs of the hind tibiae are of slightly unequal length.
