collected in Chili. 7 



Some males are darker throughout than the type, the 

 fringe of the primaries being less sericeous, and the 

 abdomen ochreous instead of stramineous. 



11. Laora ohscura, n. s. 



^ . Primaries above greyish fuliginous, fringe grey ; 

 wings as wide as in Z/. latior, but apparently with longer 

 costal margin ; secondaries pale greyish brown ; body 

 dark greyish fuliginous, the head almost black ; antennae 

 white, with blackish pectinations ; abdomen with a few 

 ochreous hairs on the sides of the last three segments ; 

 wings below uniformly pale grey ; body below dark 

 greyish brown ; anterior femora with a lateral ochraceous 

 stripe ; a few ochraceous hairs close to the base of the 

 wings ; tibiae and tarsi blackish above. Expanse of 

 wings, 82 mm. 



Valparaiso ; one male. 



This is more distinct than the three preceding, and 

 therefore, although there is only one example in the 

 collection, I do not hesitate to regard it as a separate 

 species ; had the whole of the specimens of Laora been 

 reared from one batch of larvae it would perhaps have 

 been impossible to doubt that they were referable to one 

 variable species, the individuals of which were not only 

 inconstant in coloration, but in the form and relative 

 size of their wings ; since, however, Mr. Edmonds' note 

 makes it evident that some at least were taken at light, 

 there is no necessity for me to arrive at such an 

 improbable conclusion respecting them. It is possible 

 that Berg's Patagonian Bomhyx i deserticola, sub- 

 sequently referred by its describer to Ocnogyna, may be 

 a more specialized form of the genus Laora.
