 Schreiner, 1901). 



Colour pale yellowish. Carapace with 5 black stripes above, but 

 the median stripe short, continued only a little distance behind the 

 median eyes ; the inner of the paired strips narrow, subparallel, 

 somewhat remote from the outer stripes and connected before their 

 middle with the latter by a transverse bridge, and often again at the 

 outcurved anterior ends, the posterior ends converging and free ; 

 outer stripes not very broad ; sides of the carapace with a row of 

 4 black-bordered yellow areas on each side and with black marks 

 above and below these. Abdomen pale yellow, with transverse black 

 stripes and rows of spots. Sternum with 4 curved, marginal black 

 stripes on each side and 3 pairs of black spots near the centre.

 lines (sometimes absent in fourth pair), the distal part with 2 black 

 bands ; patellae blackened at apex (except above) ; tibiae w T ith 

 black mesial and distal bands, the anterior pairs also with a basal 

 band ; metatarsi darkened at apex. 



Horny plates on under side of abdomen with the ridges curved as
