a long way beyond the dactylus of tlie preceding segment ; bearing 

 two processes, of wbich the proximal is very small and the distal 

 very large. 



2nd pair — proximal segments stout, dactylar prolongation of the 

 second blade-like, with straight minutely denticulated inner surface, 

 rounded apex and outer surface rounded from base to apex ; distal 

 segment also blade-like, considerably longer than the dactylus of the 

 preceding segment; anterior edge of the inner surface straight and 

 simple, the posterior edge furnished with a series of minute denticles 

 is considerably thicker at its proximal than at its distal extremity ; 

 outer surface evenly rounded from base to apex. 



? . Anal tergite not saddle-shaped, antennae smaller. 

 Vulva. Basal sclerite rounded proximally, distally angled and 

 separating the two distal sclerites ; internal sclerite, from the front, 

 more or less rod-like, with perfectly straight outer border and 

 rounded apex, expanded proximally and distally, projecting consi- 

 derably beyond the external sclerite; external sclerite (the cap) 

 varying somewhat in shape, with tolerably straight inner border and 

 more or less irregularly rounded external border,, thinner at its. 

 proximal than at its distal end. 

 Length 15-40 mm. 



The species Z. chitonoides was established by Mr. Butler upon 

 certain specimens which differ from Z. hrandti in the narrower and 

 more elongate shape of the body. But this difference of shape is 

 clearly due to distortion of the tergites during the process of drying. 

 The type of Z, vugidosa cannot be separated by any reliable 

 characters from specimens of Z. hrandti.
