spines on each side of the apex of the shaft. Posterior hamules t^vice 

 as long as wide, tips rounded and barely reaching the edge of the 

 sexual fossa. A short but distinct spine on antero-ventral edge of 

 segment 3 next the seminal vesicle. Segment 10 with a narrow, high, 

 forked, dorso-apical projection (see figs. 94-96). Superior appendage, 

 viewed from the side, with a conical base from the ventral side of 

 which a long, basal, pointed branch extends ventrad and behind the 

 uptiuTied dorsal branch of the inferior appendage. Viewed from the 

 side the inferior appendage very short, the inferior branch merely a 

 rounded tubercle, the superior branch short, turned up and covering

the inferior branch of the superior appendage. Viewed from above 

 the superior appendages are sigmoid-conical and diverge widely from 

 the median hne. 



Female, structure. — Differing from male as follows : Pro thorax with 

 posterior lobe divided by two notches in its posterior edge into a 

 median and two lesser lateral portions. Viewed from side the pos- 

 terior edge of hind lobe presents two concavities, one from base to 

 lateral notch and one between notch and apex (see figs. 62, A-B). 

 (Mesostigmal lamina, fig. 93.) A minute spine on apex of ventrum 

 of segment 8. Segment 10 three-fifths as long as 9. Superior ap- 

 pendages two-thirds as long as segment 10, ends obtuse. Genital 

 valve reaching almost to apex of segment 10, its ventral edge smooth 

 but covered with short hairs. Palp two- thirds length of 10.
