terior side; tarsi {^) — anterior dijffering from other Australian 

 species by being less dilatate, naked beneath, basal joints rounded 

 and not produced at inner apical angle; posterior very thick, 

 second joint widest, third, fourth and fifth successively narrower, 

 fifth as long as third and fourth together, wide at base, parallel 

 on sides, its upper surface with a deep sulciform concavity on 

 outer side at base.* Length 24, breadth 6*8 mm. 



Rab. — Q, : Cairns District (Coll. Sloane). 



This remarkable species was taken at Kuranda, near Cairns, by 

 Mr. F. P. Dodd. Its position seems to be between Hyperion and 

 Morio; it might have been regarded as the type of a new genus 

 or subgenus and substantial reasons given for so treating it, but 

 I prefer to look upon Morio as a genus which varies sufficiently 

 to include M. crassij^es as an aberrant form. Its size, incised 

 clypeus, and the strange form of the legs, in combination differen- 

 tiate it from all other Australian Morionides.

Genus P e r i g o n a. 



P. RUFiLABRis, Macl., var. iNFUSCATA, n.var. 



Closely resembling F. rufilahris, Macl.; head jDiceous, clypeus 

 and labrum ferruginous, prothorax ferruginous, sometimes a little 

 infuscate, elytra subpiceous with margins ferruginous. Differs 

 from P. rufilahris by head not such a deep black, elytra with the 

 piceous colour extending much more generally over the elytra (the 

 basal third not rufescent); prothorax (O'S x 1-2 mm.) less convex, 

 a little less narrowed to base, anterior angles more prominent, 

 margin a little explanate at basal angle Length 3-3-3-8, breadth 

 1-4-1 'Go mm.
