Group Austropassalinae n. 



Apparently allied to the south american group PassalincEy 

 but differing by having six well-marked joints in the club of 

 the antennse. 



Antenns with a six-jointed club; clypeus without distinct 

 apical furrow; f rontal horn well developed, free. Labium 

 without »Schild». P^xternal interstices of elytra typically 

 differentiated. 



Austropassalus n. g. 



Body comparatively flat and depressed. The three en- 

 larged apical joints of antennae much larger than the three 

 ones in the club. Clypeus symmetrical, its front edge not 

 separated by a furrow, but slightly elevated, and at the same 

 time marked off from the parts behind it by different sculpture, 

 with three obtuse teeth, one in the centre and one on each 

 side. Dorsal surface of head flat, without well marked ridges, 

 f rontal horn very much resembling that of the PassalincE, lon g 

 and free, and bent forward. Prothorax with a distinct me- 

 dian line. The five external interstices of elytra are very 

 different to the five interiör ones, being distinctly reticulat- 

 ed, and separated from each other by opaque spaces, where 

 the ordinary line of punctures is modified into a row of isolat- 

 ed, distinct, specks. Labium without any sign of »Schild», 



convex 



5. Austropassalus Hultgreni n. sp. (Figs. 5-7). — Body 

 depressed, black and glossy. Head in many respects showing 

 similarity to that of the group Passalince. Clypeus flat, 

 opaque, without marked ridges. The »Stirnleisten» are very 

 indistinct. The teeth obtuse and not very prominent; front- 

 al horn strongly developed, rising from a very broad base, 

 then, af ter a forward bend, assuming a horizontal position, 

 bifid at the apex, with a little hollow in the dorsal sur- 

 face and scattered fine spöts; from the base of the horn runs 

 a ridge in the direction of the eye; head behind the eyes 

 strongly punctured. Antennae of the ordinary type, the fourth
