I have examined the male genitalia of a large series of specimens 

 from localities throughout the range of this species and find that 

 the variation in shape and setation of the gnathal arms is random 

 and not of specific or subspecific significance. The same is true 

 of the degree of rose shading on the hindwing. 



The color characters given in the key serve to distinguish L. elegans 

 from L. seminigrescens ; however, further comparative remarks are 

 impossible until additional specimens of L. seminigrescens are obtained. 



Loxotoma seminigrescens Meyrick 



Plate 1 (fig. 2) ; Map 1 

 Loxotoma seminigrescens Meyrick, 1932, p. 288. 



Alar expanse 37 mm. 



Antenna brown. Head orange brown overcast with rose; second 

 segment of labial palpus brown overcast with rose exteriorly, apical 

 segment brown. Forelegs reddish brown deepening to fucous at last 

 tarsal segment; midlegs white with dorsum of tibia, entire tarsi 

 brown, hindlegs missing. Thorax, tegula, forewing as in elegans 

 except ground color orange brown. Hindwing dark gray on basal 

 half, becoming rosy brown posteriorly; cilia rose basally, brown 

 beyond. 



Male genitalia; Unknown. 



Female genitalia: Unknown 



Type: In the Naturhistorisches Museum, Vienna. 



Type-locality: Petropolis, Brazil. 



Distribution: Known only from the type-locality. 



Through the kindness of Dr. Fritz Kasy and the Naturhistorisches 

 Museum, Vienna, I have had the opportunity to study the type of 

 this species, a female, which is the only specimen known and which is 

 without abdomen. The orange color and dark hindwings afford 

 separation from L. elegans; however, final judgment concerning its 

 validity must be reserved pending the acquisition of additional 

 material and study of the genitalia.
