One female; San Antonio dc Jesu, Brazil. [A. N. S. Phila.] 

 This specimen is equal to the measurements given by Saussure.^® 

 I have adopted the above generic and specific names in preference to 

 Phihalosoma lepeletierii, agreeing with Kirby" that page prioritj' 

 should be applied to this case, regardless of usage as to one sex having 

 a systematic value superior to the other. 



Genus PTERINOXYLUS Serville. 

 1839. Pterinoxylvs ServiUe, Orthopteres, p. 226. 

 Type. — P. difformipes Serville ( = Haplopus eucnemis Burmeister). 



Pterinoxylus eucnemis (Burmeister)?

 [Interior Brazil.] 



Three specimens, all immature ; two males, one female ; Tucurrique 

 and Turrialba, Costa Rica. (Schild and Burgdorf.) [U. S. N. M.] 



This series, while all immature, range in size from 46 to 93 millimeters 

 in total length, and agree perfectly with each other in the character 

 of the lobes and nodes. The figure of Burmeister's type given by 

 Westwood^^ appears to represent a form having the lobes more rounded 

 and not so distinctly acuminate as in the Costa Rican individuals. 



Genus BACTERIA Lepeletier and Serville.

 Type. — Mantis ferula Fabricius { = arumatia Stoll)." 



^* As T have not had the opportunity to examine more than a single specimen of 

 the genera which Kirby (Trans. lAnn. Soc. London, 2dser., VI, p. 464) transferred 

 to tlie Heteronemince {Bacunculince Auct.), I have not accepted his action. It is 

 very evident that Bacteria at least is closely related to the Heteronemince, but 

 Kirby's remarks are so brief that we glean little regarding the characters on 

 which he proposes the removal. 



^^ Of the four original species of the genus but one (perfoliatus) has been 

 removed, and that to Ceroys by Serville in 1S39.
