The sexual area consists of a semilunar hairy plate behind 

 the genital openir.g ; in front and between the eoxae there is 

 a long and broad plate, which lias the hindm. st margin 

 slightly concave in the middle and is provided with many 

 hairs ; laterally this plate is nearly connected with the corners 

 of the posterior plate. In the area between the two })lates 

 several niinute internal organs are seen througii the integu- 

 ment (fig. 2 a). 



Antenvoi (figs. 2b-c). — The flag el In m (fig. 2 b) is com- 

 posed of four hairs, of which the foremost is the longest and 

 the hind mo.st theshtrtest; tb.ey are all, especially the first 

 and fourth, provided with a few teeth along the front margin. 

 The four hairs are so closely connected at the base that 

 probably they can only be moved together. The immovable 

 finger bears about five teeth on the inner dorsal n)argin. 

 A well-developed lamina exterior is present, as mcU as a 

 lamina interior ; the latter has a strongly folded plate-shaped 

 portion which, when seen from below, covers the proximal 

 dentated lobes. Tiiese lobes are placed obliquely to 

 the longitiidinal axis of the finger and directed forwards 

 and downwards, each covering the hinder or basal margin 

 of the following when seen in ventral view. The terminal 

 spine, which seems to be placed on a slightly higher level 

 than the lobes, has four teeth. The yulea (fig. 2 c) is 

 moderately long and slender and distally provided with fi\e 

 teeth of different sizes. The serrida exterior consists of 

 about twenty-nine teeth, of which the median ones are the 

 shortest and almost squarely truncate ; the basal tooth is 

 distinctly longer than the following, but only slightly enlarged 

 distally ; the last one is, again, a little more pointed and 

 longer than the preceding. 



Maxilla (fig. 2 a). — The maxillae are granular and densely 

 covered with rather long, slender, and distally dentated 

 hairs. The lamina maxiltaris is rather short. 



Palps (figs. 2d-e). — The palps are indistinctly granular 

 and everywhere beset with rather long, more or less cla^ate 

 hairs ; those of the fingers Mre pointed and amongst them are 

 some tactile hairs. The trochanter, which is longer than 

 broad, has a distinct stalk ; the inner side has an almost 

 semicircular outline from the stalk to near the tip ; the outer 

 side bears two blunt prominences, of which the ventral and 

 proxiniid is the longer, while the more dorsal is less marked. 

 The/ewmr, which is twice as long as bri;ad and broader than 

 the trochanter, has a distinct stalk ; this is most marked 

 when seen from the side, because the upper surface is much 

 more distinctly and suddenly raised than the exteiior; the
