very near to Saussure's Prosthacusta , which was based on P. 

 mexicana Saussure (Nemobius circumcindus Scuddcr). Until 

 we are able to compare the two species we prefer to place borclUi 

 at least tentatively in Prosthaaisia. Giglio-Tos' species is 

 markedly different from the genotype, but in the important 

 generic features it seems to fully agree. Bruner has referred 

 horellii to Walker's Luzara, but we are not able to form any clear 

 idea of this genus from Walker's description, while Kirl^y, from 

 type examination, considers it a distinct genus related to Para- 

 gryllus and Ectecous, where horellii certainly does not go. We 

 state this with the genotypes of both genera before us. Bruner's 

 Luzara boliviana is extremely close to, if not identical with, horellii, 

 a possibility he refers to in the original description. 



Endecous itatibensis new species (Plate X, figs. IS, 19, 20, 21 and 22.) 



This species is referred to Endecous with some doubt, as it has 

 the dorsal surface of the caudal metatarsi biseriately serrulate, 

 and the median tibiae have four distal spurs, instead of the former 

 being uniseriately serrulate and the latter with three spines, which 

 are supposed to be characters of E. arachnopis, the genotype. 

 However, the agreement of most of the other characters is such 

 that we do not feel warranted in generically separating this species 

 wiihout more knowledge of the genotype. From the description 

 of arachnopis the present species differs in the much more elongate 

 tegmina of the male, in the mediastine vein of the same having a 

 number of rather weak branches, in the larger size and in the 

 distal spine of the dorso-internal margin of the caudal tibiae 

 being but slightly smaller than the others in the series, instead of 

 very small. 



From the species E. lizeri, which is being described elsewhere 

 by us, the present species differs in its smaller size, more ample 

 tegmina with more usual and regular venation, in the less pro- 

 jecting lateral lobes of the pronotum, in the less extensive sub- 

 genital plate of the male, and in the less attenuate and more 

 expanded distal palpal joint. The female of itatibensis is not 

 known.
