with the outer chitinous plate and the latter not extending in mesad as a 

 distinct lobe. Coxal piece of anterior gonopod broad proximally, abruptly 

 reduced near middle to about half the basal width, the inner edge continuous, 

 the outer abruptly bent in near middle of length, the distal narrower part still 

 broad and plate-hke and distally rounded. Tclopodite longer than coxa, 

 distally simple, broadly rounded. An opening between the two divisions 

 anterocaudally leaves distal part of posterior gonopod exposed. 



Number of segments, forty to forty-three. 



Length (female), 34 mm.; width, 3.5 mm. Males smaller. 



606. Spirobolellus kurandanus, sp. nov. 



Type.— M. C. Z. 4,803. Paratypes.— M. C. Z. 4,804, 4,805. 

 Queensland: Kuranda (W. M. Wheeler). 



Characterized in color by a series of triangular black marks along the mid- 

 dorsum, each mark being connected with the succeeding one by a narrow 

 black line, the bases of the marks cephalad. The triangular markings set 

 off on each side by a zig-zag yellow line. Below this on each side the 

 prozonite blackish, the dark area narrowing and fading out ventrad; the 

 metazonites light ferruginous. Anal segment and collum dark, but valves 

 in part lighter. Head with a black area between eyes continued ventrad as a 

 bifurcate band to the yellow labial region; antennal sockets bordered on mesal 

 side with black, the space between this and the middle dark band areolated 

 with a network of black as in also the vertex. Legs fulvous. Antennae with 

 dark markings. 



Sulcus of head distinct above and below as usual. Eyes triangular, rather 

 small, fully twice their diameter apart; ocelH in four series, e g. 6, 5, 4, 2. 

 Antennae very short. 



Collum only moderately narrowed below, the lower end widely rounded, 

 the caudal margin just above it convex, the anterior shghtly concave. 



Below the level of the pores the prozonites marked with striae which curve 

 up cephalodorsad and finally turn transversely; just above the pore these 

 replaced by some short curved impressions but the middorsal region smooth, 

 without striolations. A series of horseshoe-shaped markings along the posi- 

 tion of the suture, which is not evident, being represented by a sKght depres- 

 sion. Metazonites above vaguely longitudinally rugose; below with the 

 usual striae. Pores very small, a httle in front of the middle of the meta- 

 zonite but widely removed from the position of the suture. 



Anal scutum rounded behind, just covering the valves. The latter with 

 mesal borders but weakly elevated, not set off by distinct sulci. 



Number of segments, forty-four. 



Diameter (female), 2.8 mm.
