Aiistralidn and Tdsmanidn Coleoptera. 147 



tially concealed, second moderately stout, about the lenijth of 

 first, but distinctly longer than the exposed portion of that 

 joint, third to eighth each slightly longer than wide, ninth to 

 eleventh forming a thin club, ninth about twice the length of 

 eighth, and at base no wider, but slightly dilated to aj^ex, 

 tenth slightly shorter and wider than ninth, and very feebly 

 transverse, eleventh about as long as ninth and tenth combined. 

 Prothorax slightly longer than wide, sides widest and evenly 

 roimded somewhat nearer apex than base ; near base Avith a 

 strong transverse impression marked by three small foveae. one 

 in middle and one on each side ; punctures indistinct. Elytra 

 almost as long as wide, sides gently rounded, angles distinctly 

 rounded ; with six small basal foveae ; each with two faint 

 dorsal striae ; punctures rather indistinct. Abdomen with seg- 

 ments rather long on upper surface, and with strong margins ; 

 the lower surface with a narrow, strongly ridged intercoxal 

 process, second to fourth segments narrowed across middle, 

 fifth strongly narrowed, and, with the fourth and sixth, flat- 

 tened. Metasternurn vaguely depressed along middle, but with 

 a conspicuous sub-conical tubercle on each side, half way 

 between coxae. Front trochanters very feebly dentate ; four 

 hind tibiae spinose at apex. Length 2 mm. 



? • Differs in having antennae somewhat shorter, abdomen 

 almost parallel-sided, instead of rather strongly dilated pos- 

 teriorly, and convex along middle of under surface ; meta- 

 sternurn unarmed and tibiae without apical spines. Length 

 1 2-3 mm. 



Hah. — W. Australia : Swan River, Bridgetown, from nests 

 of Fonera lutea (A. M. Lea). 



Seen from the side each eye appears fto be at the point 

 where two conical tubercles should meet, one concealing the 

 base of the antennae, the other on the lower surface of head. 

 In appearance the antennae are suggestive of some species of 

 Heterognathus of the Scydmaenidat. The dorsal striae are 

 very faint, and the two on each elytron are seldom visible from 

 the same direction ; they arise from the basal foveae, and are 

 fairly distinct to the basal third, but are vaguely traceable to 

 beyond the middle. The tubercles on the metasternurn are very 

 distinct from the sides.
