Rhysodes ichthyocephalus, n.sp. 



Black, shining; legs diluted with red. 



Head deeply bisiilcate; median lobe terminated considerably 

 before base and impunctate; lateral lobes punctate, basal portion 

 subreniform and feebl}' separated from the apical portion. An- 

 tennc>3 with the 1st joint cylindrical and longer than wide, 2nd-l 0th 

 transverse, 11th very little longer than wide. Prothorax deeply 

 trisulcate; the ridges lightly punctate, of equal length and all 

 swollen in middle, the two middle ones slightl}^ converging towards 

 each other at apex; lateral impressions narrow and running out 

 at apex. Elytra not much wider than prothorax; seriate-punctate, 

 punctures partially effaced towards suture; interstices rounded, 

 fifth slightly raised, posteriorly becoming subcarinate, waved and 

 joined to the sutural interstice. Under surface with scattered 

 punctures of moderate size, but large and rather dense on apical 

 segment; each of the other abdominal segments with a transverse 

 series of punctures, small in middle, larger and denser at sides. 

 Length 6, width 2 mm. 



Hab. — Cairns, Q. (Maclea}' Museum). 



In general appearance not unlike ligyiarius, but the median 

 lobe (which has an outline somewhat similar to that of a fish) of 

 the head of different shape and terminated considerably before 

 the base. 



Rhysodes abbreviatus, n.sp. 



Black, shining; legs diluted with red. 



Head irregularly impressed and divided into six lobes; the 

 median lobe largest, suboblong, slightly produced in front (the 

 apex just before middle) and continuous to base, near base 

 impressed on each side; basal lateral lobes rather large and sub- 

 reniform, and not very distinctly separated from eyes ; apical 

 lateral lobes long, narrow and feebl}'- transversely impressed; 

 apical median lobe small. Basal joint of antennae scarcely longer 

 than wide, 2nd-10th transverse, 11th slightly longer than wide. 

 Prothorax deeply trisulcate ; the ridges impunctate and all 

 swollen in middle, the median ones noticeably shorter than the
