282 PROCEEDINGS OF THE ACADEMY OF [May-Oct., 



We have compared this individual with an adult female from La 

 Piedrita, Venezuela (II, 16, 1911; Stewardson Brown), in the collec- 

 tion of the Academy, and as far as can be determined from the im- 

 mature specimen, which is in the instar preceding maturity, the two 

 represent the same species. Redtenbacher has recorded the species 

 from Bahia. 



LISTROSCELINAE. 



Listrocelis atrata Redtenbacher. 



1891. Listrocelis atrata Redtenbacher, Verhandl. k.-k. Zool.-bot. Gesell. 

 Wien, XLI, pp. 544, 545. [Nova Friburgo (Neu Freiburg), State of Rio 

 de Janeiro, Brazil.] 



Espirito Santo, Brazil. One male. [Hebard Cln.] 



This specimen is somewhat larger than the measurements given 



by Redtenbacher, but it does not appear to differ in other features. 



From the closely related L. carinata Karny, the present specimen 



differs, as does the description of atrata, in the longer and strongly 



arcuate process of the left mandible and the straight cerci. 



The localities given above are all known for the species. 



CONOCEPHALIXAE. 



Conocephalus iriodes Relin and Hebard. 



1915. Conocephalus iriodes Rehn and Hebard, Trans. Amer. Entom. Soc, 

 XLI, pp. 231, 258, pi. XXI, fig. 6, pi. XXII, figs. 5 and 2.3, pi. XXIII, 

 figs. 12 and 13, pi. XXIV, fig. 5. [Cuidad Bolivar and Maripa, Vene- 

 zuela; Kaiteur (type and allotype) and Rockstone, British Guiana; Ireng 

 River near Roraima, British Guiana; Bonito, Pernambuco, Brazil.) 



Bonito, State of Pernambuco, January 7 and 15, 1883. (A. Koe- 

 bele.) One male. [U. S. N. M.] 



This specimen, like the female from the same locality previously 

 recorded by us, has been immersed in alcohol or a similar preserva- 

 tive, so that to-day its distinctive coloration is almost entirely lack- 

 ing. The caudal limbs and the cephalic and median ones on the 

 left side are missing, but all the important structural features of the 

 species are evident. The tegmina are longer than in any of the 

 other males measured by us, being but shghtly shorter (18.3 mm.) 

 than those of the female from the same locality previously measured. ^* 



Conocephalus saltator (Saussure). 



1859. X[iphidium] saltator Saussure, Rev. et Mag. de Zool., 2e ser. XI, p. 

 208. [Guiana.] 



Bonito, State of Pernambuco, January 27, 1883. (A. Koebele.) 

 One male. [U. S. N. M.] 



This specimen is of the brachypterous type.
