314 NEW SPECIES OF AUSTRALIAN COLEOPTERA, 



apical third. Meta- twice as long as mesosternum, the two com- 

 bined as long as abdomen. Third tarsal joint strongly bilobed, 

 entirely concealing true 4th joint except from below. Length to 

 eyes If, rostrum ^; width ^ (vix) mm. 



//a6.— N. Queensland (Mr. G. Masters), Barron Falls (Mr. A, 

 Koebele). " In decaying timber." 



Hexarthroides, n g. 



Head rather small. Eyes small, prominent, coarsely granulate. 

 Rostrum subcylindrical, parallel. Antenne moderately slender, 

 funicle 6-jointed; club 3-jointed. Protliontx widest across middle, 

 longer than wide. Scutelhim almost invisible. Eli/Ira subcylin- 

 drical, parallel, apex acuminate. Anterior co.ae subapproximate: 

 tibial hook distinct; tarsi pseudo-tetramerous, 3i'd joint moderately 

 bilobed. Body elongate, narrow, strongly sculptured, feebly 

 pubescent. 



Although possessing a six-jointed funicle, I think this genus 

 should go in with the Cossu aides as limited by Mr. Wollaston; 

 he himself places Uexarthruvi (also witli a six-jointed funicle) 

 with them, and the present genus certainly cannot be placed with 

 the Onycholipides. I possess no Australian genus with which it 

 can be satisfactorily compared, and from Hi^xnrihrtim it appears 

 to differ widely. 



Hexarthroides punctulatum, n.sp. 



Narrow, subconvex. Piceous-black ; eyes brown, antennte dull 

 red, base of femora, apex of tibiie and the tarsi tinged with red. 

 Punctures with microscopic sparse pubescence, longest beneath. 

 Head feebly transversely strigose at base, it, the rostrum and 

 prothorax with coarse dense punctures, elytra striate-punctate, 

 the punctures coarse, approximate ; under surface with strong- 

 regular punctures; head almost impunctate, and microscopically 

 granulate; intermediate abdominal segments feebly and sparsely, 

 apical more densely and strongly punctate; femora shallowly 

 punctate and strigose. 



Rostrum parallel-sided, except for a feeble dilatation to receive 

 the antennae. Prothorax very feebly constricted near apex, and
