taceous. Costal area of the tegmina broad and rounded on their basal 

 half, narrowed beyond. Transverse parallel veins not so prominent 

 as figured for pnuctuJata I^runner (see Monog. Phancropt., pi. II, 

 fig- 23). 



Length of body, cf , 16 nnn., of pronotum, 3.5 mm., of tegmina, 26 

 mm., width of tegmina, 5.25 mm., length of hind femora, 16 mm. 



Habitat. — The type and another male specimen are at hand. They 

 were collected by J. Steinbach at Puerto Suarez, Bolivia, during 

 November and January. The type is in the Carnegie Museum of 

 Pittsburgh. 



3. Aniarella proxima (Brunner)? 



Aniara proxima Brunner, Addit. Mon. Phaneropt., p. 58 (1891); Rehn, Proc. 

 Acad. Nat. Sci. Phila., 1913, p. 360. 



Specimens of a second species belonging to the genus Aniarella in 

 the present collection are referred with some doubt to Brunner's 

 proxima. 



Genus Hyperophora Brunner. 



Hyperophora Brunner, Mon. Phaneropt., pp. 16, 125 (1878); lb., Addit., Mon. 

 Phaneropt., pp. 7, 58 (1891); Rehn, Proc. Acad. Nat. Sci. Phila., 1907, pp. 

 371-376, figs. 1-8. 



The insects, which comprise the genus Hyperophora, are rather 

 numerous and confined to the middle portions of South America. 

 They are especially abundant in portions of southern Brazil, Paraguay, 

 eastern Bolivia, and northern Argentina. Specimens are at hand 

 from several localities, but in such numbers that they have been set 

 to one side for later study. This course has been decided upon 

 because of the apparent variation in color, size, width of tegmina, 

 etc., found among the specimens coming from a single locality.

This is also a tropical South American genus. It contains rather 

 small, but more or less mottled and otherwise variegated insects 

 with the characters indicated in the preceding table of genera. Two 

 species have been characterized heretofore, to which a third is now 

 added. They may be separated as follows:
