submedian veins pearly opaline ; costa washed with buff ; an 

 ill-defined transverse dusky discal stripe ; external area pale 

 rosy cupreous : secondaries sericeous whitish, the costal area, 

 veins, and fringe buff, slightly rufous ; a discocellular spot 

 and five or six longitudinal dashes on the veins across the 

 disk black : pectus whity-brown ; legs rufous-brown, with 

 ferruginous spines and whitish-tipped spurs ; venter rosy, 

 with the anal tufts slightly yellower. 



Expanse of wings 43 millim. 



One male of this very distinct species. 



4. Peridroma hostilis. 

 Agrotis hostilis, Walker, Lep. Het. xi. p. 737 (1857). 



Four examples.

 mediate in character between the two. 



5. Peridroma clerica. 

 Agrotis clerica, Butler, Trans. Eat. Soc. 1882, p. 129. n. 27. 

 Three examples of this Chilian species.
