MICROLEPIDOPTERA OF JUAN FERNANDEZ ISLANDS — CLARKE 49 



fuscous with pale annulations at ends of tibiae and tarsi. Abdomen 

 grayish fuscous with whitish scaling beneath. 



Female genitalia (slide 10384): Genital plate broad; area posterior 

 to ostium membranous. Ventral lip of ostium narrowly triangular but 

 broadened abruptly at base; weakly sclerotized. Anterior apophyses 

 absent. Ductus bursae membranous except extreme posterior portion. 

 Inception of ductus seminalis slightly before posterior third. 



Type: Masatierra: El Camote, 600 m. (Mar. 17, 1951). 



Described from the unique female type. The type specimen lacks 

 the right forewing and is otherwise in only fair condition but is a 

 striking insect closely related to loxia. The chief point of external 

 difference between paralexia and loxia is the presence of the large 

 ovate light spot in the central area of the forewing of the former and 

 absence in the latter. The genital plate of paraloxia is broader than 

 that of loxia and the ventral lip of ostium is much more slender in 

 loxia than in paraloxia.

Labial palpus white; basal segment with a pale grayish-fuscous 

 spot outwardly; second segment with longitudinal, oblique, grayish- 

 fuscous band from base, dorsally, to apex ventrally; third segment 

 suffused grayish fuscous. Antenna, scape white with fuscous spot 

 dorsally, remainder sordid whitish suffused grayish fuscous. Head 

 white suffused grayish fuscous anteriorly and laterally. Thorax and 

 ground color of forewing white, the former with pale grayish-fuscous 

 mottling; extreme base of costa narrowly blackish fuscous; from 

 slightly before middle of costa, inwardly along vein 12, then out- 

 wardly to middle of dorsum, an irregular fuscous transverse line; from 

 costa, at apical fourth, an outwardly oblique fuscous, broken line 

 extends to vein 6, then continues to tornus nearly parallel to termen; 

 between the two transverse lines a white diamond-shaped spot 

 narrowly edged with fuscous; termen marked with six blackish- 

 fuscous spots at the ends of the veins; remainder of wing irregularly 

 irrorate or lightly suffused with grayish fuscous, paler basally; cilia 

 paler than wing, apical cilia white. Legs white, suffused and spotted 

 with fuscous; markings of hindleg confined to grayish-fuscous tarsal 

 spots. Abdomen grayish fuscous above, paler beneath. 



Female genitalia (slide 10383): The unusually large spatulate 

 process, arising on the ventroanterior edge of the ostium and extend- 

 ing almost to the tip of the ovipositor, is an extreme development of 

 similar processes found in other species of Crambidae.
