Two females and one male from the Province del Sara, Bolivia, 

 are referred to Scudder's species bivittatum. They were collected by 

 J. Steinbach at an altitude of 350 meters. C. M. Ace. No. 5058. 

 There is another female from the Rio Japacani, eastern Bolivia, taken 

 by the same collector in Feb., 191 5. C. M. Ace. No. 5573.

 ? Paracornops longipenne Bruner, Proc. U. S. Nat. Mus., XXX, p. 662 (1906). 

 Cornops longipenne Rehn, Trans. Am. Ent. Soc, XLII, pp. 286, 287 — in discussion 

 of synonymy, Sept. 23, 1916; Ib., I. c, XLIV, p. 204 (1918). 



There are three males and three females of this insect at hand. 

 They all come from Cayenne, French Guiana, where they were taken 

 in April, 1917. C. M. Ace. No. 5897. 



Coming from a locality so comparatively near to and similar to 

 that, from which Acrydium longipenne De Geer, was derived, there 

 can scarcely be room for doubt as to their identity. The specimens 

 seem to agree in every respect with the original description, as well 

 as with most of the characters mentioned by Rehn in his discussion 

 referred to aboAC, and based upon almost certainly authentic material.
