MICROLEPIDOPTERA OF JUAN FERNANDEZ ISLANDS — CLARKE 63 



places as Chile, Straits of Magellan, etc., which means that they were 

 caught by J. J. Walker himself. Obviously, Warren's statement in 

 print is a slip." The California record, therefore, is in error and the 

 species should be dropped from our North American lists because 

 the specific identity of the Juan Fernandez material is a certainty. 



In this species there is a marked sexual dimorphism characterized 

 by a contrasting pattern in the male and obscure pattern and somber 

 coloring in the female. The conspicuous pale costal spot of the male 

 forewing, repeated on the underside, is obscured and scarcely dis- 

 cernible in the female. On the underside of the female forewing, 

 however, this spot is nearly as pronounced as in the male. The 

 forewing of the female is light brown above, overlaid with vinaceous 

 scales. The ill-defined fuscous markings of the forewing consist of 

 two subcostal spots preceding and following the pale costal spot; a 

 transverse line at one-third, another subterminally, and a patch of 

 scales at the base of wing dorsally. 



In all probability fumipennis will have to be transferred out of 

 Pionea but that must be left to the revisers of the pyraloids. For 

 the present I am leaving the species in Pionea. The male and female 

 genitalia are figured from specimens from Masatierra, slides, cf, 

 10400 and 9, 10638.
