body with the first pair of shoulders. The lateral edges are 

 almost parallel, only slightly constricted in the middle ; 

 posteriorly very regularly rounded. The anterior part of 

 the shield is very dark brown, the anterior two thirds 

 of the median streak is light brown, and provided with 

 darker markings, whilst the posterior third part of the 

 same streak, and the two lateral streaks, are darker brown, 

 and provided with lighter markings ; I have delineated on 

 purpose 8 very light and striking spots, viz. two on each 

 side and four posteriorly. Hairs : two pairs of vertical hairs, 

 of which the second pair directed outward. Two hairs on 

 the shoulders I, directed outward. Anteriorly a nearly 

 uninterrupted row of hairs almost following the anterior edge. 

 The median streak with the usual number and position ot 

 hairs. Quite on the posterior edge a pair of long hairs. 

 The lateral streaks with much more hairs, standing in 

 oblique rows, which in the anterior portion run backward 

 and outward and in the posterior ' portion forward and 

 outward. Weak skin with numerous small bristles, arranged 

 in rows which run forward and outward. A median streak 

 behind the shield quite hairless. 



Ventral side. Tritosternum like in the male (see fig. 5). 

 Sternal shield (fig. 11) trapezoidal, darkbrown ; anteriorly 

 with a light-coloured transverse oblong projecting piece 

 on which the first pair of long sternal bristles is planted. 

 Lateral edges a little concave. Posterior edges with three 

 concavities. The second and third pair of sternal long 

 bristles are planted in lighter-coloured spots. Genital 

 shield dumbbell-shaped, light-coloured, only with its own 

 pair of long bristles. Metasternal shields apparently absent, 

 at least the metasternal bristles are planted in a chitinous 

 bar which more resembles a portion of the pedal shields. These 

 latter are only discernible outside of the foveolae pedales. Anal 

 shield perfectly of the same shape as in the male (see fig. 2) ; 

 in pregnant females (fig. 11) it seems configurated otherwise, 

 when observed in an oblique direction. Inguinal shields 

 small, round. Peritrematic shields absent. Peritremata like
