appears to be slightly undulating, but there are no con- 

 spicuous depressions. 



MlCRORHAGUS SERRATICORNIS, n. Sp. 



Brownish-black, appendages of a dingy-red, tarsi paler. 

 Moderately and almost uniformly clothed with short 

 stramineous pubescence. 



Head with crowded, partially-concealed , punctures. 

 Antennae not very long, second joint short, third dilated to 

 apex, about as long as fourth and fifth combined, fourth 

 lightly produced on one side at apex, fifth more strongly, 

 sixth to tenth still more strongly produced (subpectinate), 

 eleventh thin, longer than tenth. Prothorax transverse; 

 with crowded asperate punctures ; basal third with a narrow 

 median carina. Elytra almost parallel-sided to near apex; 

 base with crowded asperate punctures, but becoming smaller 

 posteriorly; with vague remnants of striation, but becoming 

 distinct on apical half near suture and on the tips. Prosternal 

 sulci rather deep in front, becoming shallower and deeper 

 behind, where the width is about equal to that of the 

 propleural parallelograms, these about thrice as long as wide. 

 Length, 3 mm. 



Hab. — New South Wales: Tweed River (Blackburn's 

 Collection). Type (unique), I. 5727. 



A dingy species. The sides of the prothorax, basal 

 angles, carinated front margin, and lateral spurs from same 

 are almost exactly as in the preceding species. 



MlCRORHAGUS ATER, n. Sp. 



Deep-black, knees and tarsi reddish. Clothed with 

 short, dark pubescence, becoming stramineous and somewhat 

 longer at base of prothorax and of elytra, and on head. 



Head with crowded, more or less concealed, punctures. 

 Antennae much as in preceding species. Prothorax 

 moderately transverse, parallel-sided, except for the rounded 

 front angles, strongly convex, hind angles strongly produced 

 and acutely carinated, with a short medio-basal carina, front 

 margin finely carinated, and on each side with a short spur 

 projecting backwards ; with dense and small but not asperate 

 punctures. Elytra with crowded asperate punctures on basal 

 fourth and on tips, the intervening space with smaller but 

 more clearly-defined ones; with feeble remnants of striation. 

 Prosternal sulci rather deep, somewhat dilated posteriorly, 

 where the width is about equal to that of the propleural 

 parallelograms, these about thrice as long as wide. Length, 

 33 mm.
