The specimens before me, four males and four females, which I 

 locate here, are from Quatro Ojos, Department of Santa Cruz, Province 

 del Sara, Bolivia, and from the Rio Bermejo, Province of Salta, Argen- 

 tina. They are all slightly larger than those coming from Asuncion, 

 Paraguay, and first determined by me as Stal's Orphula pagana. 

 They may represent Giglio-Tos' Orphula minor, as suggested by Rehn 

 (Proc. Acad. Nat. Sci., Philad., 1906, p. 17). If so, they are very 

 closely related to pagana, which as shown by Rehn (Trans. Am. Ent. 

 Soc, XLII, pp. 175-176, 1916) is the same as Walker's earlier de- 

 scribed Chysochraon filatus, of which it becomes a synonym. These 

 specimens were collected by J. Steinbach in March and April, 191 3, 

 and May, 1914. 



38. Paratruxalis filatus minor (Giglio-Tos)? 



For synonymy, etc., see Rehn, /. c, pp. 175-176. 



Four females coming from the Province del Sara, Bolivia, may 

 belong here. They were taken during the period January-April, 

 191 3, by Steinbach, and form a part of C. M. Ace. No. 5058.

 p. II (1894); Bruner, Ann. Carnegie Mus., VIII, p. 11, 14 (1911). 



Among the material collected by J. Steinbach in the Province del 

 Sara, Bolivia, are four males and one female, which are referred to 

 this species. They were taken in the months of February, March, 

 April, and December at an approximate altitude above sea-level of 

 350 meters.
