Bruner: South American Crickets. 389 



Antennae slender, of moderate length, the basal segments about ecjual 

 in diameter to the width of the rostrum between them. Pronotum 

 somewhat transverse, the humeral angles broadly rounded; lateral 

 lobes a little deflexed outw^ardly anteriorly, the lower margin rising 

 towards the base; front or apex very broadly and shallowly emargin- 

 ate, the base squarely truncate; the disc provided behind with a rather 

 large, but shallow, > -shaped depression, the apex of which is directed 

 cephalad and also with a median longitudinal line. Tegmina moder- 

 ately large in the male and covering about three-fifths of the abdomen, 

 in the female lateral and extending but part way across the basal 

 abdominal segment, or entirely missing. Cerci moderately heavy 

 and long, nearly or quite the length of the hind femora. The latter 

 fairly robust and having the apical portion heavy; anterior and middle 

 legs slender, the auditory opening rather large on the inner, but 

 minute on the outer face. Last ventral segment of the abdomen of 

 the male broadly scoop-shaped, upturned; the supra-anal plate sub- 

 quadrate, the outer apical angles provided with large, slightly out- 

 wardly directed tubercles. Ovipositor robust at its base and slender 

 at the apex, gently falcate.

 collection of the Carnegie Museum.

Habitat. — There are three specimens, two males and one female, in 

 the collections made by J. Steinbach, which seem to agree with the 

 description of Giglio-Tos' Ectecous borellii. It certainly is not this 

 genus and I have referred it to Luzara instead. It is in reality quite 

 closely related to the preceding, if the two are not forms of the same 

 species.
