CHAMBERLIN: myuiopoda ok iiik Australian REGION. 151 



In the first tergite the free margins of the lobes much less eonvexly 

 elevated. Median region very similar but the tubercles in g en eral 

 rather coarser. Border lobes of other tergites rather more thick- 

 curd and soinew lial more coarsely granular. 



The anal segment very similar. Anal scale longer with the caudal 

 margin between the tubercles strongly convex or angular instead of 



oearh straight.

PlLOCHILUS, gen. nov. 



Agreeing in general with Aipotropis. The first tergite not quite 

 completely covering the head in dorsal view, a little of the latter 

 being exposed in front. Most readily distinguished from the genus 

 mentioned in having the lobed free border vertical in position and 

 extended ventrad into a supplementary band the lower edge of which 

 fits against the head; in the other genus such a supplementary band 

 is weakly indicated only at each caudolateral end of the border. The 

 anal tergite is larger, the cauda extending prominently beyond the 

 paired dorsal processes. The lobes of the keels are more serrate in 

 form. The male gonopods are in general similar; but the terminal 

 branches of the blades are longer and stouter, the seminiferous one 

 blade-like, the outer branch wide, curved. Head entirely smooth, 

 upper part not tubercular as in Aipotropis. Antennae long, all 

 articles much longer than thick; fifth and sixth much thickened; the 

 fifth longest.

Metazonites deep dusky or blackish brown above, the under surface of 

 keels crossed longitudinally by a paler band which may be obscure; the 

 pleural region of both metazonites and prozonites reddish or chestnut to black; 

 venter pale brown to fulvous; prozonites above with a median longitudinal 

 reddish brown or chestnut band set off on each side by a wide fulvous stripe. 

 Head chestnut, much darker above level of antennae, the dark region enclosing 

 numerous lighter areas. Antennae with first four articles chestnut, the fifth
