Blaberus parabolicus Walker

 Ecuador.] 



Para, Para. (C. F. Baker.) One male. [A. N. S. P.] 

 Manaos, Amazonas. One male. [Mus. Comp. Zool.] 

 Abuna, Bolivia. (Stanford Expedition.) One male, one 

 female. 

 This species has been found to be distinct from trapezoideus 

 Burmeister, with which it has generally been synonymizcd. An 

 examination of Scudder's Blabera armigera show his insect to be 

 the same as Walker's species, while Bolivar's aequatoriana is 

 clearly identical. The synonymy of Bolivar's species Avith 

 Walker's older parabolicus has already been established by Kirby. 

 Giglio-Tos' record of Blabera trapezoidea from three localities in 

 eastern Ecuador-^ doubtless relates in its entirety to this species, 

 as two of the specimens so determined by him from Valle del 

 Santiago are now before us and belong to parabolicus. 



The Para specimen is somewhat aberrant when studied with 

 other material, but is is clearly the same species. 



Blaberus scutatus Saussure and Zehntner

Natal, Rio Grande do Norte. (W. M. Mann.) One female. 

 Cearc4 Mirim, Rio Grande do Norte. (W. M. Mann.) One 

 male 

 These specimens agree very fully with the description of the 

 species. In this difficult genus it is very hard to make determi- 

 nations without physical examination of the types, as the descrip- 

 tions are by no means as comparable and comprehensive as 

 necessary for satisfactory work.
