nearly related to it. The anterior genital plate (fig. 2 h, a), 

 vliicli is hairy in the middle, is situated between the coxie and 

 the ])osterior plate; it is well raised in the middle, prolonged 

 backwards Avith a low eoncavity in the posterior margin ; the 

 lateral part gets rather sviddenly and most distinctly shorter. 

 The posterior genital plate, which is broad and long, is dis- 

 tinctly wider than long ; its hinder margin is moderately 

 raised backwards, the lateral margin, after a shallow eon- 

 cavity in which the first pair of stigmata (s.) is partly placed, 

 is suddenly bent inwards, merging into tlie anterior margin. 

 This is distinctly curved forwards on each side, and in the 

 middle provided with a well-marked curvature, which fits 

 into the convexity of the anterior plate. The median and 

 anterior portion of this system is more raised than the 

 lateral and posterior region when seen from below. From 

 the front margin ,to the middle a longitudinal shallow de- 

 pression extends, having a moderate elevation on each side, 

 which cover the usual ram's-horn-shaped organs. The 

 posterior part of this plate is distinguished from the anterior 

 plate by an indistinct transverse groove (fig. 2b,(/). Hairs 

 are found at least along the front margin. 



Palps (fig. 2 d). — The conical tubercles are larger than in 

 the female. The palps are both longer and stronger. The 

 trochanter has the interior margin more strongly curved and 

 the stalk more distinct. The femur is very clumsy and 

 scarcely twice as long as broad. The hand is comparatively 

 broader and the fingers shorter than in the female. 



Coxa: (fig. 2 6). — The first three pairs of the coxse are 

 shaped as in the female, but the fourth is very different. It 

 is most narrow in the middle and enlarged towards both ends, 

 slightly so inwards, but most distinctly outwards. The pos- 

 terior side is distinctly concave, the anterior moderately 

 convex, Avith a low median concavity. Near the interior 

 posterior corner the entrance-opening (fig. 2 b, c) of the 

 coxal sac is seen. This sac (comp. p. 135) is almost as long 

 as the coxa, which it almost fills, and is enlarged distally; 

 the inner wall is provided with many subconical elevations 

 or tubercles, each bearing one or several hairs, which most 

 often are bifurcated from the base or middle, but sometimes 

 divided into several branches. Near the opening these 

 eminences are arranged in a kind of half- funnel. 



Colour. — The colour is perhaps more bright, especially the 

 purple of the anterior portion of body.
