chamberlin: ittbiopoda of the Australian region. 127 



last tWO articles similarly white. Legs whitish. The species also 



resembles Bdoswn in having the dorsal surface roughened with gran- 

 ules or minute setigerous tubercles; but this roughening is very much 



less marked with t ho hairs much sparser and rather weaker. The 



keels are proportionately smaller and obviously less elevated, the 

 middorsal region appearing more arched, and the serrations on the 

 lateral edges are much slighter. The keels of the eighteenth and nine- 

 teenth segments not abruptly reduced as in the other species. The 

 cauda is shorter and distally broader, subtruncate, not furcate, with 

 angle on each side acute as in setosum. 

 Length (female), 14 mm.

Type.— M. C. Z. 4,995. Paratype — M. C. Z. 4,997. Solomons : 

 Auki (W. M. Mann). 



Similar in coloration to the preceding species but at once recogniz- 

 able in having the antennae and legs uniformly pale throughout 

 excepting that the last joint of the former has a narrow dark band 

 about its proximal end. Antennae more slender with the joints shorter. 

 The keels are wholly without serrations laterally and those of eight- 

 eenth and nineteenth segments not abruptly reduced as in the other 

 form. A most marked difference is that the tergites in the present 

 species are nearly smooth, showing but vague traces of roughening 

 and essentially glabrous, the hairs being scattered, short, and weak. 

 The transverse furrow of tergites weak in strong contrast with the 

 condition in the other species. 



Length (male type), near 10.5 mm. Female paratype much 

 stouter and near 13 mm. in length. 



354. Mimosoma sequens, sp. nov. 



Type.— M. C. Z. 5,012. Solomons: Fulakora (W. M. Mann). 



This species resembles M. glabrum in having the tuberculation of 

 the dorsum obliterated or reduced to fine obscure granulations with 

 corresponding essential absence of hairs from most of surface. The 

 tergites highly arched. Transverse sulcus obscure. Keels much 

 reduced but clearly set off above by sulci; the posterior angles of 

 most not at all produced, but in the posterior region the spinous points 

 are evident though minute and inconspicuous. Cauda short, trun-
