preserved. In the Tepic series, which is dried alcohoHc, practi- 

 calh' all coloration is lost and only a few specimens show faint 

 traces of antennal annuli. 



The present species is kno^^^l to range from Colon and Ancon, 

 Panama, northward to Orizaba, Cuernavaca and Tepic, Mexico. 



Specimens Examined: 24; 6 males, 15 females; 1 immature male and 2 

 immature females.

 [U. S. N. M.]. 



Ancon, Canal Zone, Panama, XI, 16, 1913, (H.; in marshy spot at foot of 

 hill in tall grasses), 1 cf , 1 9. Allotype.

Scudderia ungulata Scudder 



1898. Scudderia ungulata Scudder, Proc. Amer. Acad. Arts and Sci., 

 xxxiii, p. 280, fig. 6. [Tepic, Mexico.] 



The present species is one of the largest and most robust of the 

 genus. The males are readily separable from other species by the 

 characters of the production of the supra-anal plate, in which rela- 

 tionship to S. mexicana is shown, but in the present insect this 

 plate is much more simple. The females are distinguished by 

 having much the largest ovipositor of any species of the genus, 

 with the apex of the same much less rounded. This ovipositor 

 is gently curved and not at all bent, a condition found elsewhere 

 in the genus only m the apparently more primitive species S. sep- 

 tentrionalis and aS. hemidactyla. 



We here select as single type the female described by Scudder 

 from Tepic, Mexico, and now in the Hebard Collection. The 

 described male is consequently the allotype; it is in the same 

 collection. 



All of the material from Tepic is dried alcoholic but the series 

 of seven specimens (six in A. N. S. P.) from Guadalajara shows the 

 normal coloring of the species of the genus with lateral angles 

 of the pronotum immaculate and both tegmina and antennae 

 unicolorous, green and broA\ai respectively.
