originate from Panama. Of the specimens examined by the present 

 author, two others are labeled as originating from Peru, It seems 

 therefore quite probable that some confusion has occurred in the label- 

 ing of the Walsingham specimen. Future records perhaps will bring 

 more clarity to this problem. 



Superficially dadodes might easily be mistaken for some form of 

 the highly variable volcanica Butler; however, dadodes has 10 costal 

 streaks of the forewing instead of 11 streaks as in volcanica, and 

 there is a distinction in the genitaha of these two species. The male 

 of dadodes has the uncus less narrowed basad, the valva is somewhat 

 shorter and therefore looks relatively broader, the aedeagus has a 

 ventral keel, and the cornutus and the cuneus are shaped differently. 

 The female genitalia are rather similar in both dadodes and volcanica, 

 but the antrum of the first species is less incm'ved laterally, and the 

 signum is not discernible.

 Pseudatteria leopardina. — IMeyrick, 1912, in Wagner, Lepidopterorum catalogus, 

 pt. 10, p. 16; 1913, in Wytsman, Genera insectorum, fasc. 149. p. 22. — 

 Walsingham, 1914, Biologia Centrali-Americana, Lepidoptera Heterocera, 

 vol. 4, p. 269, pi. 8, fig. 7. 



Male genitalia. — Uncus scaphiform-spatulate, dilated and 

 rounded apically, at tip with a short, acute point directed ventrad, 

 and a minute, setose papilla beneath this point. Valva subrect angular 

 with a roimded external margin; sacculus dilated at base, and then 

 narrowly extended along ventral margin of valva, not reaching 

 external angle. Aedeagus thick but not stout, with a slight "waist" 

 at middle, and a robust distal process; cornutus elongate with two 

 apical points; no cuneus. 



Female genitalia. — Sinus vaginahs flatly infundibular; lamella 

 antevaginalis narrow. Antrum tubular with two broad, lateral 

 colliculi, one on each side; cervical portion of corpus bursae mar- 

 morate; cestum indiscernible; corpus bursae rather broad; signum 

 divided by a transverse carina in two unequal portions, caudal one 

 larger.
