Falces vertical, conical, moderately stout, yellowish. 



Maxilla longer than broad, somewhat spathulate, inchned

 opposite coxae ; chocolate-brown. 



Abdomen large, base obtusely pointed, lateral angles 

 prominent, pointed posteriorly; sensibly convex above, sides 

 slope inwards ; creamy-white transverse band connects angles, 

 thickly marked with large irregularly-shaped creamy-white 

 flecks, which are intersected by lake-purple vein-like lines ;

 median pair separated by rather more than their diameter, 

 nearly twice that space from hind-lateral eyes ; anterior row
