284 NOTES ON AUSTRALIAN COLEOPTERA, 



tuberculo nigro sat magno oniatis, humeiis fere ut R. 

 bicaudati, Boisd., sed antrorsum magis productis.

This species must I think be referred to Rhachiodes (in spite of 

 a considerable difference between its outline and that of most of 

 the previously described members of the genus) on account of the 

 following structural characters : Antennal funicle 7-jointed, scape 

 not quite reaching eye, scrobes straight (median or slightly ante- 

 median), eyes finely facetted, ocular lobes of prothorax distinct, 

 elytra tuberculate, ventral segment 2 longer than 3 and 4 together, 

 femora unarmed, tibiae mucronate at apex, tarsi wide and com- 

 paratively short, their claw joint projecting not much beyond the 

 lobes of the 3rd joint. I should judge that it is structurally near 

 R. signaticollis, Chev., and nigropunctatus, Chev., which their 

 author seems to regard as forming a distinct section of Rhachiodes. 



The peculiar tuberculation of the elytra renders this insect very 

 oasily recognisable, each elytron having no inequalities except the 

 humeral callus and two small but very conspicuous black tuber- 

 cles, one (the larger of the two) on the 2nd interstice at or slightly 

 in front of its middle, the other on the 4th interstice a little 

 nearer to the apex. The general squamosity, which is very 

 dense, is of a pale testaceous-brown colour, variably clouded with 

 a darker shade. The 2nd joint of the funiculus is considerably 

 shorter than the first and not much longer than the 3rd.

Piceus, squamis griseo-albidis vestitus, in elytrorum utroque 

 macula albida transversa paullo pone medium posita, pedibus 

 antennisque (harum apice inf uscato) rufescentibus ; rostro 

 quam prothorax (maris sat manifesto feminpe vix) breviori ; 

 prothorace pone apicem sat fortiter constricto, leviter canal i- 

 culato \ elytris fortiter striatis, interstitiis subconvexis.

Seems to be a typical Bayous^ — a genus not previously reported 



from Australia. Coloured very much like B. inceratus^ G-ylh, but
