712 AUSTRALIAN AND TASMANIAN PSKLAPHID^, 



BaTKISODES INSIGNICOLLIS, 11. sp. 



(J. Pale reddish-castaneous. Clothed with rather long, pale 

 pubescence, and with numerous long hairs scattered about. 



Head with a narrow and almost straight impression close to 

 apex, the impression indistinctly connected on each side with a 

 distinct round fovea close to each eye; forehead feebly impressed 

 along middle. Antennte long and thin, none of the joints trans- 

 verse, seventh distinctly longer than eighth or sixth, eleventh 

 somewhat shorter tlian ninth and tenth combined. Prothorax 

 slightl}' transverse, widest at about apical third, thence strongly 

 narrowed to apex and rather less, but still strongly, to base; 

 near base with a strong transverse impression, with a subfoveate 

 expansion in middle and another on each side, disc strongly 

 elevated, with a wide impression on each side of its middle, the 

 same connected with the latero-basal fovea, and irregularly con- 

 tinued across the middle not far from the apex; with an almost 

 closed transverse impression slightly nearer apex than base; with 

 irregularly distributed punctures. Elytra with dorsal strite dis- 

 tinct at base and shallowly traceable almost to middle; shoulders 

 unarmed. Metasternum rather deeply and widely impressed 

 along middle. Abdomen flattened along middle of under surface, 

 apical segment with a feeble apical node. Trochanters unarmed. 

 Length 2-2^ mm. 



2- Ditt'ers in being slight!}' less robust, antennae somewhat 

 thinner, prothorax le.ss inflated near apex, with lateral and basal 

 impressions only, and disc less convex, the cephalic impressions 

 shallower, metasternum very feebly impressed along middle, and 

 abdomen nowhere flattened.

Readily distinguished from all previously described Australian 

 species by the shape of the prothorax. On careful examination 

 all the prothoracic impressions can be seen to be connected, 

 although from most directions the transverse submedian one 

 appears to be closed; immediately in front ot this impression the 

 surface from some directions appears to be laised into obtuse
