100 INSKCUTOR INSCITI^ ME:nSTRUUS 



phiireiis of Palisot de Beauvais, from the island of Santo Do- 

 mingo, may be this species, but in the absence of Antillean ma- 

 terial this question must remain undecided. The following 

 localities are indicated on the specimens before me : 



St. Jean, French Guiana, 1 female (W. Schaus) ; Cayenne, 

 French Guiana, 1 female (Schaus); Maroni River, 60 miles 

 up, British Guiana, 2 females (Schaus) ; Bejuco River, Pan- 

 ama, 1 male (Schaus) ; Cabima, Panama, May 19, 24, 26, 31, 

 1911, 4 females (A. Busck). Bartica, British Guiana, 2 fe- 

 males, and Caura Valley, Venezuela, 1 female (collection C. 

 W. Johnson). Reported from Brazil by Walker and from 

 Mexico by Bellardi.

Nat. Hist., ser. 6, vol. 20, p. 21. 



There are no specimens of this species before me and it is 

 treated here in order to establish the above synonymy. It evi- 

 dently resembles the preceding species in coloration, but dif- 

 fers in the presence of a long appendix on the upper branch 

 of the third vein, as indicated by both authors. Bellardi's 

 specimen was a female, Townsend's a male, and both came 

 from the same general region, the State of Vera Cruz in 

 Mexico. Bellardi states that the frontal stripe of the female 

 is broad, which should further serve to distinguish it from 

 inanis. The wings are unspotted, as in the latter species. He 

 makes no mention of a frontal callosity.
