Habitat. — A pair of locusts coming from Puerto Suarez, Bolivia, are 

 referred here. They were collected during the period including 

 November, 1908, to January, 1909, by J. Steinbach. They come from 

 a locality with an elevation of 150 meters above sea-level.

Habitat. — There are two female specimens of this genus before me 

 as I write, both of which I am inclined to refer to Giglio-Tos' species. 

 One was taken at Taquara, Brazil, and the other at Santa Cruz de la 

 Sierra, Bolivia. The former specimen is a trifle smaller than the 

 measurements given for this sex by Giglio-Tos, i. e., length of body, 

 21.5 mm., of tegmina, 15 mm., of hind femora, 10 mm. It was 

 collected in September, and is also labeled "Accession No. 2966." 

 The other specimen is very noticeably larger, even exceeding the 

 measurements given by Rehn for his Oxybleptella pulchella (Proc. U. S. 

 Nat. Mus., XXXVI, pp. 136-139, figs. 21, 22, 23(1909)). This last 

 specimen measures as follows: Length of body, 25 mm., of tegmina, 

 18 mm., of hind femora, 12 mm. In color the two insects are some- 

 what similar, only differing in minute particulars. The eyes of the 

 larger individual are conspicuously banded parallel to their anterior 

 margin alternately with brown and yellow, there being about ten 

 such bands on the anterior two-thirds of the eye. 



Genus Inusia Giglio-Tos.

 (1897); Bruner, Journ. N. Y. Ent. Soc, XIV, p. 151 (1906); Ib., Biol. Cent.- 

 Amer., Orthopt., II, pp. 212, 259 (1907-8). 



This is another tropical American genus of the subaquatic locusts. 

 At least eight species have thus far been recognized. Representatives 

 occur from middle Mexico to northern Argentina, as well as in some 

 of the West Indian islands. Two of the species occur in the material 

 now at hand.
