diagnostic value of this feature. We have also before us for study 

 a pair from Paramaribo, Surinam (K. Mayo) and a female from 

 Bartica, British Guiana (March 25, 1913; H. S. Parish), all belonging 

 to the Academy. The five specimens show there is a very decided 

 amount of variation in the intensity of the tuberculation of the 

 fastigium, but all are clearly referable to the same species. Both 

 Guianan females have three spines on the dorso-caudal margin of 

 the median tibise, while the Paramaribo male has three spines on 

 this margin on one limb and four on the other. 



The species has already been recorded from Para by Walker and 

 Bruner. 



Acantheremus elegans Kamy. 



1907. Acantheremus elegans Karny, Abhandl. k.-k. zool.-botan. Gesell. 

 Wien, IV, heft 3, p. 9, fig. 1. [Surinam.] 



Para. (C. F. Baker.) One female. 



This specimen fully agrees with the original description of the 

 species, differing only in the slightly greater size of the specimen 

 before us. 



Neoconocephalus nigropunctatus (Redtenbacher). 



1891. Conocephalus nigropunctatus Redtenbacher, Verhandl. k.-k. zool.- 

 botan. Gesell. Wien, XLI, pp. 380, 391, pi. Ill, fig. 32. [Upper Amazon; 

 Brazil; Surinam; Cuba; Cayenne.] 



Para. (C. F. Baker.) Three males, one female. 



Benevides, Parc4. (H. H. Smith.) Two males. [U. S. N. M.] 



Contamano, Rio Ucayali, Peru. October to December, 1912. 

 One male, two females. 



The Contamano specimens have been immersed in a liciuid pre- 

 servative and in consequence all have lost their original coloration, 

 but they are identical with the Para male, and all fully agree with 

 the original description. 



Bruner has recorcled^^ the species from Para and Benevides. 

 Neoconocephalus fratellus (Griffini). 



1891. Conocephalus frater Redtenbacher (not of Kirby, 1890), Verhandl. 



k.-k. zool.-botan. Gesell. Wien, XLI, pp. 381, 399. [Cuba; St. Vincent, 



Lesser Antilles; Trinidad; Brazil; Upper Amazons.] 

 1899. Conocephalus fratellus GriflSni, Misc. Entom., VII, p. 5. (New name.) 



Para. (C. F. Baker.) One male. 



The tegmina are appreciably shorter in this specimen than the 

 measurements given for those of the same sex by Redtenbacher; 

 otherwise the specimen is typical.
