 (LXXVII), figs. I. le, i.

 at Corumba and Chapada, Brazil, during the months of September 

 and October by H. H. Smith. Carnegie Museum. 



Genus Paragryllus Guerin.

 Orth. (1874), p. 441; Mem. Soc. Geneve, XXV (1878), p. 411; Biol. Cent.

This is also a tropical American genus and representatives occur 

 from IMexico to Brazil including the Antilles. No specimens of the 

 genus appear to be among the material before me, unless we can include 

 Walker's Luzara rufipennis from Colombia, and an apparently new 

 form from Puerto Suarez, Bolivia, a characterization of which follows: 



51. Luzara rufipennis Walker? 



Luzara rufipennis Walker, Cat. Derm. Salt. B. M., I (1869), p. 103; Kirby, Syn. 

 Cat. Orth., II (1906), p. 65. 



Habitat. — There is a single mutilated male specimen at hand 

 from Chapada, Brazil, which is doubtfully referred to Walker's 

 Luzara rufipennis. The shape and color of the maxillary palpi and 

 pronotum are somewhat difil'erent from what is indicated in Walker's 

 description. Otherwise it agrees well with the several specimens 

 described under the name. 



52. Luzara boliviana sp. nov. 



A moderately large and robust insect for the group. Body glabrous, 

 on the hind femora and abdomen above inclining to tomentose. 

 General color dark piceous, with the occiput, the disc of the pronotum, 

 tegmina, and hind tibiae deep ferruginous, merging into piceous. 

 Venter and the inner face of the hind tibiae pallid, inclining to testace- 

 ous. Apical and subapical segments of the maxillary palpi large and 

 clear i\ory-white, gi\ing to the insect a very striking appearance. 



Head somewhat narrower than the anterior portion of the pronotum, 

 the occiput short and evenly rounded, the vertex and front narrowed 

 between the antenuie; the eyes fairly large, but not prominent; the 

 ocelli also quite large, the posterior pair located well forward, the 

 anterior one situated on the upper face of the perpendicular front.
