272 Mr. F. P. Pascoc 07i new Genera 



Differs from A. liisoriiis in the narrriwer outline, short tliird 

 anteimal joint, elytra with the apical half ])lue and their aj)ice3 

 obliquely truncate. Aphiorliynclius was j)ropo.sed Ijy Lacor- 

 daii*c for the former species, which I had refeiTcd to Psilo- 

 onorplio^ but wliich is certainly distinct, on account of its en- 

 tire finely granulated eyes. D. apicalis is another species. 

 Both are from Queensland, not from Western Australia, as 

 Lacordaire has stated.

(Stenoderinffi.) 



Charactcros iit in Apliiorliynclio, sod antennis corpore hrc\*ioribus. 

 articulis tortio ot scqucutibus suba)qualibu.s, duolms ultiniis quara 

 prajcedcntibus crassioribus ; scapo vix elongate, basin prothoracis 

 baud attingeutc, apice clavato ; femonhus breviusculis. 



The characters of the antenna and the comparatively short 

 femora, the posterior not extending beyond the middle of the 

 secoiul abdominal segment, give this genus a different a])pear- 

 ance from AjyhiorJii/nchus. From Demomisls it is differentiated 

 by the length of its muzzle and the non-approximation of the 

 antenntB to the eyes. A front view of the head is given on 

 PI. XIII. lig. 7.

Like ]\[. aciculari's, this species has the four tubercles on the 

 })rothorax much reduced, the two anterior ])eing nearly ()])solete. 

 i'he anknnu^ have the terminal joints numifcstly thicker than 

 the preceding ones.
