Ti-PE.— M. C. Z. 4,794. Paratypes.— M. C. Z. 4,795, 4,798. 

 Queensland: Kuranda, 2000 ft. (H. L. Clark, W. M. Wheeler). 



In this species the median plate is most like that of Z. digitulm 

 Brolemann in its form; the median process is similarly long but is 

 less parallel-sided, narrowing moderately to a little beyond the middle 

 and then a little widening into a somewhat spatulate end-region with 

 acuminate tip; the outer (basal) lobe of each arm is much broader and 

 projects more freely, the arch formed by the arms is rather longer with 

 the arms less divergent above their bifurcation but similarly curling 

 about the bases of the gonopods above. The coxal piece of the ante- 

 rior gonopods distad of its middle narrowing to a slender process in 

 line with its mesal border, the outer edge strongly sloping, the mesal 

 continuing its even course, the process distally curving a little mesad. 

 The telopodite is elongate and narrowed distad but is distally much 

 broader than the anterior or basal segment, parallel sided, not acumi- 

 nate as in Z. digit id us, barbed on ectal side near apex and again near 

 middle of length. Posterior gonopod in general similar to that of Z. 

 digitulus but much less deeply incised distally on ectal side. 



The prozonites vary from deep brown to black in color; the meta- 

 zonites are red. Antennae and legs bright ferruginous. Anal seg- 

 ment and the head and collum lighter, grey-brow^n, the collum 

 margined with red. 



Sulcus of head distinct across vertex and below, absent from frontal 

 region. Eyes trapeziform with the base caudad, the latter convex 

 but other sides straight; somewhat less than ti^ice their diameter 

 apart; 6, 7, 7, 7, 6, 4, 3. The first four joints of the antennae are 

 nearly glabrous, the fifth and especially the sixth hairy. 



Lower wing of collum with both the anterior and the caudal margin 

 slanting to its angle; lower edge oblique, rising anterodorsad, a little 

 incurved; margination as usual; surface strongly coriarious in its 

 markings. Sutures well marked, straight, removed from the pore 

 opposite which is not curved. On the anterior segments the prozo- 

 nites are marked with transverse striae both above and below, longi- 

 tudinal striae occurring only on the metazonites below, the latter 

 above simply coriariously roughened. Farther caudad the prozonites 

 are marked for some distance below the level of each pore with a series 

 of striae rising obliquely from the suture and above the suture with a 

 series of circular and horseshoe-shaped impressions on the line of 

 the suture. The metazonites striate only beneath. The dorsal
