578 STUDIES IN AUSTRALIAN ENTOMOLOGY, NO. IX., 



narrowed to base, elytra reddLsh instead of piceous, antennae 

 longer and less compressed, the apical joint in particular longer. 



Pediomorphus ruficollis, n.sp. 



Depressed ; prothorax broader than long, hardly cordate, punc- 

 tulate on each side near base ; elytra finely punctate-striate. 

 Nitid ; head black ; prothorax testaceous-red (usually infuscate 

 along base and apex); elytra piceous-black; antennte, palpi, and 

 legs testaceous; abdomen piceous-brown. 



Head small, smooth, convex; very lightly biimpressed between 

 antennae; eyes convex, rather prominent; antennae slender, filiform, 

 apical joint short, compi'essed-fusiform. Prothorax laevigate, 

 widest a little before middle (1-15 x 1-35 mm.), emarginate at 

 apex, truncate on base; apex and base of equal width; sides 

 rounded on anterior two-thirds ; roundly narrowed to apex, 

 obliquely narrowed to base; anterior angles distant from head,^ 

 obtuse; basal angles obtuse; border narrowly reflexed, extending 

 round anterior angles on each side of apex; median line finely 

 marked; lateral basal impressions wide, their whole area punctu- 

 late, the bottom forming a linear impi'ession; posterior marginal 

 setae rising from a puncture placed in a slight dilatation of the 

 border at each basal angle. Elytra parallel on sides (3x1 '75 mm.),, 

 widely rounded at humeral angles, depressed on disc, abruptly 

 roundly declivous to sides from fifth stria; apex rounded, lightly 

 sinuate on each side; striae linear, finely and closely punctate; 

 interstices depressed. Metastei-num punctate on each side ; 

 episternum of mesosternum and metasternum punctate. Ventral 

 segments finely rugulose except in middle. Length 4'3-5, breadth 

 1-7-2 mm. 



H<xb. : N.S. Wales — Urana District (Sloane; plentiful sheltering 

 under sticks and dried cow-dung in company with P. planiuscidus, 

 Chaud., near the edges of a swamp on the Colombo Plains Run, 

 twenty miles north from the town of Urana, 11th July, 1895). 



A distinct species difi'ering from the others of the genus by its 

 colour; also from P. planiusculus and P. macleayi, SI., by its 

 smaller size and punctate area on each side of base of pi'othorax.
