scales interspersed with numerous fine setae, the latter 

 becoming long on tibiae. 



Rostrum moderately long, median carina feeble 

 Antennae comparatively long and thin, first joint of fnnicle 

 slightly longer and conspicuously stouter than second. Pro- 

 thorax lightly transverse, sides moderately rounded, median 

 line feebly impressed; with numerous feeble granules, the 

 depressions about which appear vermicnlate through the 

 clothing. Elytra at base exactly the width of base of pro- 

 thorax, but disinctly wider at basal fourth, thence gently 

 rounded to apex; with regular rows of large, partially-con- 

 cealed punctures; interstices not separately convex, but the 

 fifth and seventh slightly wider than the others. Basal 

 segment of abdomen with dense punctures, bounded externally 

 by a distinctly curved carina, the ether segments almost 

 impunctate. Front coxae widely separated ; hind tibiae- 

 acutely dentate at inner middle, inner apex acutely spined. 

 Length, 4 mm.

The curvature of the abdominal carina is midway between 

 that of the species DT)e and ee of the 1914 table of the 

 genus; but the species may be readily distinguished from the 

 members of those groups, except sydneyensis, by the hind 

 tibiae : sydneyensis has much longer and denser setae on the 

 upper-surface, and ciothing otherwise different, larger eyes 

 and front coxae less widely separated. The gentle slope of 

 the elytra is not at all interrupted by separate convexity or 

 the interstices. 



Mandalotus tibialis, n. sp. 



c* • Dark reddish-brown or blackish, some parts (and 

 including the antennae and tarsi) more or less castaneous. 

 Densely clothed with muddy-grey or ashen, obscurely-varie- 

 gated scales; interspersed with numerous stout setae; front 

 tibiae conspicuously but not densely ciliated. 



Rostrum rather short, carina not traceable through 

 clothing. Antennae moderately long and thin ; second joint 

 of funicle slightly longer and thinner than first. Prothorax 

 moderately transverse, sides rather strongly rounded and 

 widest across apical third, median line narrowly impressed ; 

 apparently without granules. Elytra distinctly wider than 

 prothorax at base, and somewhat sinuous there, owing to the 

 elevation of the third interstice on each, parallel-sided (except 

 for a small post-humeral tubercle) to beyond the middle, 

 somewhat irregular on and about apical slope : with rows of 

 large, partially-concealed punctures, becoming smaller pos- 

 teriorly. Front coxae rather widely separated, middle coxae
