of the claval vein and bordering the claval suture. Cuneus 

 grayish translucent, the apex, a small point along the inner 

 margin and a second near the basal angle, black; the paler 

 part usually showing some brownish or reddish coloration. 

 Membrane fuscous, a large pale area just beyond the smaller 

 areole and the tip of the cuneus, divided by a small fuscous 

 spot which touches the margin; central area more or less in- 

 vaded by paler, brachium distinctly pale at apex of areoles. 

 Legs: coxae and bases of femora pale ; front and intermediate 

 femora with a series of irregular reddish brown to fuscous 

 spots ; posterior femora blackish, forming the background for 

 many large and small irrorations, the pale patches most numer- 

 ous and broadly joined on the inner side, an irregular pale 

 annulation a short space before the apex with a second nearer 

 the middle but interrupted on the outside. Tibise annulated 

 with fuscous and pale; the front pair banded with fuscous at 

 apex, narrowly at the knee and twice between these points ; 

 intermediate pair with the apical band becoming pale, the 

 whole apical half being more pale than fuscous ; posterior pair 

 infuscated, irregularly spotted with pale, broadly pale on the 

 basal one third, delimited by blackish on the inner side at base 

 and by a distinct annulation at the middle; spines pale to 

 brownish ; tarsi . fuscous, arolia erect and diverging at the 

 apices. Venter: clothed with prominent yellowish hairs, in- 

 fuscated, yellowish on the ventral side except the genital seg- 

 ment which is narrowly pale along the median line and fre- 

 quently at the sides near the base of the claspers. Genital 

 claspers and fiagellum distinctive of the species (pi. i, fig. i). 



5. Length 5.7 mm., width 2.05 mm. Very similar to the 

 male in coloration ; imperfect or poorly colored specimens can 

 never with certainty be distinguished from the females of 

 closely related species.
