n. 22 1875. 



Wheeler, Psyche, VI, p. 545 1893. 



Taschenberg records this species, now placed in the Genus 

 Enicospihis, from Illinois (North America), and Rosario 

 (South America) taken from Saturnia cecropia. This is a 

 well-known Old World species and the determination was 

 probably a mistake.

 rather flat, flavous, immaculate. Abdomen long, petiolate ; apex com- 

 pressed, flavous, shining ; ovipositor short, incurved. Wings fuscous,

This description is too brief to be distinctive. 

 Ophion obscurus Fabr. 



Taschenberg* records this species from Illinois, North 

 America, and Mendoza, South America. It is a well-known 

 Old World species, and as no other record of its capture 

 exists it is probably due to an erroneous determination.
