Sapucay, Paraguay. December 19 and 20, 1901. April 30, 1902. 

 February 13-27, March 2-11, 1905. 9 S'd', 12 9 9. (Foster, 

 Hebard Coll.) 



These specimens are assigned here with some little doubt, as they 

 are larger than Stal's measvirement of the female type (length 25 

 millimeters). 



The females all show more or less blacki.sh-brown maculations on the 

 tegmina, and the males have the caudal femora strongly rose-colored 

 with the genicular regions blackish. In the latter respect they appear 

 to approach the very brief characterization of australis, but the an- 

 tennae are longer and the general coloration rather different. The 

 latter character is of very uncertain value in this genus, as the extremes 

 of one species are qviite different, considering A. occidentalis a repre- 

 sentative form. 



Amblytropidia australis Bruner. 



1904. [Amblytropidia] australis Bruner, Biol. Cent.-Amer., Orth., II, pp. 62,

Chapada, Brazil. April and June. 2 d'd", 1 9. (H. H. Smith, 

 U. S. N. M.) 



As the original description of this species is extremely brief, little 

 can be gleaned from it to aid in identifying material. In the material 

 examined the tegmen are darker near the costal margin than elsewhere, 

 and a median dark line is present on the head and pronotum of the 

 female and the pronotum of one male. The genicular regions are 

 obscured with dark color in both sexes, but more strongly in the male 

 than in the female. 



The range of the species is here extended north of its previous limit, 



Caiza, Bolivian Chaco.
