backward and close together ; a third pair close to the edge and 

 to the posterior angle of the posterior lateral shield ; a fourth 

 pair a little before the medial posterior chitinization ; a fifth 

 pair aside of the tops of the so called joined horns ; a sixth 

 pair on the tops of the horns ; further the two long hairs on 

 the end of the abdomen ; in length they nearly equal the body ; 

 halfway they are sligtly swollen spool - shaped. Posterior to the 

 abdomen each hörn is providedwitha hyaline bi- 

 lobed little piece (compare with All. crassipes). 



Ventral side (fig. 24). E p i m e r a I joined to a sternum. 

 Epimera II long , slightly curve , extending nearly the proximal 

 ends of epimera III. Epimera III rather long, lying against the 

 posterior chitinous margin of the anterior lateral shield , and 

 apparently united with the posterior lateral shield. Epimera IV 

 enormously developed with an enormous proximal epimerite 

 extending to the posterior edge of the trochanter III. F u r t h e r 

 chitinizations; the margin of the body along the trochanteres I 

 and between epimera I and II ; the ventral margins of the anterior 

 lateral shields ; two curve commalike epimerites running from the 

 proximal ends of epimera III,. overlapping the proximal ends of 

 epimera IV, toward the top of the A - shaped epiandrium. Finally 

 two short chitinous internal bars (epimerites) are observeable 

 there where we should search for a „fifth epimeron". Shields. 

 Outside of epimera I and II and inside of epimera III and IV 

 there are narrow rudiments of coxal plates. The anterior lateral 

 shields are plainly visible and provided with dark chitinized 

 margins. The posterior lateral shields are not sufflexed ventrally, 

 so that no portion of them is noticeable on the ventral side. 

 Epiandrium enormously developed , A - shaped. Genital 

 aperture apparently also A - shaped with well chitinized lips 

 (or is this structure an internal genital apparatus ?). Penis 

 apparently minute ; I could not observe it. G e n i t a 1 s u c k e r s : 

 I could only see one pair , represented as point in the drawing. 

 Anus touching the medial rodlike chitinization , i. e. the top 

 of the original incision, excavation or cleft ; this is a second 

 proof of the chitinization being an abdominal 

 longitudinal diaphragma, a result of the rejunction of 

 two original „horns". Anal suckers relatively well developed, 

 flanking the anus and distant from each other a little more than 

 their own diameter. Hairs: Lateral hairs apparently planted 

 in the soft skin between the two lateral shields. Accessory 

 lateral hair pin-like and behind the main-hair. Further we observe 

 the following minute hairs : one pair aside of the posterior end 

 of the sternum, near the anterior end of epimera II ; on pair inside
