The antenna? are considerably more than half as long as the 

 body; the basal two joints (which are of testaceous-brown colour) 

 are a little stouter than the rest, the first nmch longer than the 

 second ; 3-7 are cylindric, slightly increasing in length (3 notably 

 the smallest of them, but evidently longer than 2), 8-10 a little 

 stouter than the preceding joints, but not longer; 11 a little 

 longer and stouter. The incrassation of the antenna? towards 

 their apex is very slight, and the only joint among the apical 6 or 

 7 that is at all markedly different from the rest is the eleventh. 



S. Australia; near Port Lincoln ; under bark of Eucalyptus. 



SYZETONELLUS, gen. nov. (? hujus familise). 

 A genere prsecedenti differt oculis multo minoribus magis promi- 

 nentibus, antennis magis gracilibus, pedibus minus 

 elongatis, tarsis intermediis quam tibia multo brevioribus 

 (illorum articulo 1° quam ceteri conjuncti sat breviori)^ 

 sutura prima ventralifere tota obliterata. 



In all other respects the characters mentioned above for 

 Syzeton may be read as applying to this genus.

The antenna are slightly longer than half the body, and are 

 moderately stout, the basal two joints scarcely different, intey^ se,. 

 stouter than the following ones, but scarcely longer, joints 3-6 

 cylindric, 7-10 obconic slightly stouter, 11 evidently stouter and 

 longer than 10, pointed at the apex. 



It is probable that the dilated hind femora (almost like those 

 of a Haltica) and the compressed hind tibite as well as the tuber- 

 culate metasternum are peculiar to the male. 



The black palpi, in contrast wdth the rufo-testaceous antenna?, 

 furnish a conspicuous character. 



Victoria ; Alpine district.
