MICROLEPIDOPTERA OF JUAN FERNANDEZ ISLANDS — CLARKE 29 



fuscous dot; cilia grayish with fuscous and white scales mixed. Hind- 

 wing pale grayish basally, shading to fuscous terminally; cilia sordid 

 whitish with a fuscous basal line. Legs fuscous, banded and irrorate 

 with white. Abdomen blackish fuscous. 



Female genitalia (sUde 10659) : Genital plate very strongly sclero- 

 tized. Ventral lip of ostium strapHke, somewhat narrower distally 

 than proximally. Ductus bm-sae membranous except posteriorly 

 where it is somewhat sclerotized. Inception of ductus seminalis at 

 about posterior fourth of ductus bursae. 



Type: Masafuera: La Correspondencia, 1150 m. (Jan. 25, 1955). 



Described from the type female and two female paratypes from 

 the same locality (Jan. 28, 1955; Jan. 3, 1955). One of the paratypes 

 from which the species is figured, is somewhat darker than the type 

 because of the more extensive development of the dark markings. 



In pattern this species is similar to annWate and, like it, is variable; 

 but xerophylla is a smaller moth and exhibits none of the yellowish 

 coloring encountered so often in annulata. In genitalia xerophylla 

 adheres to the usual type but the area around the ostium is more 

 strongly sclerotized than in most species. The ventral lip of the 

 ostium is much longer in xerophylla than in annulata as can be seen 

 by a comparison of the figures.

Alar expanse 12-14 mm. 



Labial palpus white; second segment overlaid with grayish fuscous 

 on outer surface; third segment almost whoUy grayish fuscous but 

 with some white remaining on inner surface. Antenna and head 

 grayish fuscous, the latter with a few scattered white scales on frons 

 and posteriorly. Thorax white beneath, grayish fuscous above. 

 Ground color of forewing cinereous but the whole wing almost en- 

 tirely overlaid with grayish fuscous; markings obscure; base of wing 

 grayish fuscous; from basal third of costa an outwardly oblique, 

 transverse, grayish-fuscous line extends to middorsum, the line 

 broadening out in middle of cell, forming a lobe in dorsal half of wing 

 to apical third; from apical third of costa a slender, outwardly oblique 

 line slants to about vein 5 where the end of the line widens to form a 

 small subquadrate lobe; between the end of this mark and the pre- 

 ceding transverse line is a small grayish-centered grayish-fuscous 

 spot; cilia cinereous with considerable infuscation. Hindwing light 

 grayish fuscous; cilia concolorous with a somewhat darker basal line. 

 Legs cinereous overlaid and banded with grayish fuscous. Abdomen 

 grayish fuscous with some cinereous scaling beneath.
