longitudinal grooves weaker than in ocelleus but spinulation stronger.

Food plant. — Unknown. 



Remarks. — I am greatly indebted to Dr. C. Don MacNeill, Assist- 

 ant Curator of Insects, Department of Entomology, Cahfornia Acad- 

 emy of Sciences, for making available for study the large series 

 collected by their representatives on a recent expedition to the 

 Galapagos. 



Efforts to locate the remainder of the series examined by Dr. Schaus 

 were unsuccessful; however, in view of the absence of ocelleus in the 

 extensive series of the California Academy of Sciences, it appears 

 that ocelleus does not occur in the GaMpagos and that galapagosalis 

 is an endemic species, not occurring elsewhere. 



Euchromius saltalis, new species 



FiGDREs 1, 5; Plate 1 (fig. 3) 



AIale (pi. 1: fig. 3). — ResembHng californicalis in color and 

 maculation but forewing more cream colored from base to inner 

 transverse postmedial band; and whitish patch, adjacent to terminal 

 blackish dots, with the thin line more ochreous and located midway 

 between the dots and termination of the irrorated area. 



Genitalia (fig. 1): Uncus moderately stout. Harpe with costa 

 strongly serrate, basal production rather broad, straplike and truncate 

 distally with apices subequal, one strong, hooklike and the other 

 minute. Aedeagus (fig. la) with a series of short, stout spines and 

 two elongate patches of slender spinules. 



Female. — Alar expanse 20 mm. Similar to male in color and 

 maculation. 



Genitalia (fig. 5): Ostium with two lateral adzlike sclerotizations; 

 ductus bursae long, somewhat longitudinally rugose and spinulation 

 within rather coaree and conspicuous; origin of ductus seminalis 

 about midway between ostium and tip of bursa copulatrix, two 

 subequal signa, narrow, scobinate, ridgelike.
