prothorax, sides feebly dilated to beyond the middle; with 

 rows of rather large, almost (or quite) concealed punctures ; 

 alternate interstices feebly elevated. Front coxae very 

 widely separated, middle ones each with a shining oblique 

 ridge. Length ( $ , Q), 3|-4 mm. 



9 • Differs in having the prothorax somewhat smaller, 

 elytra somewhat wider, basal segment of abdomen convex in 

 middle (instead of flat), and legs somewhat shorter, with 

 simple coxae. 



Hab. — South Australia : Adelaide, seven specimens £rom 

 tussocks (J. Ran). Type, I. 5573. 



In the 1914 table of the genus would be placed under K 

 after hh, and from all the species there placed (except 

 angustus) it differs in the middle coxae: from anr/ustus it 

 differs in being- somewhat smaller, rather more robust, with 

 the front coxae much more widely separated (almost twice the 

 distance), and with the middle coxae more conspicuously 

 carinated (the carina from some directions causes each coxa 

 to appear armed with a subacute conical tubercle). The 

 separation of the front coxae is rather more than in rvfi- 

 manus, and the elytra, although non-tuberculate, are more 

 uneven than on that species. The elytra (except perhaps at 

 their base) could not fairly be regarded as tuberculate ; their 

 base is much less conspicuously trisinuate (except for slight 

 encroachments by the third interstices it could fairly be 

 regarded as arcuate) than in humeralis. The clothing on all 

 the specimens is very dingy and somewhat obscured by mud, 

 but on two of them there are faint indications of pale spots 

 on the prothorax, and still more faint indications on the 

 elytra . 



Mandalotus subhumeralts, n. sp. 



Blackish -brown, some parts obscurely reddish ; 

 antennae and tarsi castaneous. Densely clothed with muddy- 

 brown slightly-variegated scales and with stout setae. 



Rostrum short and stout, median carina traceable through 

 clothing. Scape not very long : first joint of funicle stouter 

 and slightly longer than second. Prothorax almost as long as 

 wide, sides and base strongly rounded ; with numerous 

 granules conspicuously transversely arranged. Elytra sub- 

 arcuate and wider than prothorax at base, with a conspicuous 

 tubercular swelling on each side just beyond shoulder; with 

 regular rows of large punctures, appearing very small through 

 clothing ; odd interstices very feebly elevated above the even 

 ones. Two basal segments of abdovieii feebly depressed in 

 middle. Legs moderately stout; front coxae lightly but 

 distinctly separated. Length, 3 mm.
