456 AUSTRALIAN COLEOPTERA, WITH DESCRIPTIONS OF NEW SPECIES, 



nec crebre (capite prothoraceque nihilominus paiillo crebrins) 

 punctulatis ; antennaram articulo tertio prime manifeste longiori. 



[Long. 14, lat. f lines. 



Compared with the S. Australian insect which I take to be /. 

 (Neissa) inconspicua, Pasc, this species is evidently of a narrower 

 and more parallel form, and has the 3rd and 4:th antennal joints 

 longer in comparison with the scape. The example before me is 

 somewhat abraded, but I should judge that a fresh specimen 

 would be marked and coloured very similarly to Mr. Pascoe's 

 insect. Unfortunately in the description of /. exilis, Er., the 3rd 

 joint of the antennae is not compared in length with the scape, but 

 Erichson's species is said to be " black," with certain parts 

 " reddish pitchy;" and as the insect I am describing has no black 

 coloration whatever, and the two are found in very widely 

 separated localities, it is not at all likely that they are identical. 

 Tn all the specimens I have seen of this genus the surface of the 

 prothorax is a little uneven ; in /. inconspicua the unevenness is 

 very ill-defined, but seems to consist of one or more obscure trans- 

 verse wheals and a slightly more apparent longitudinal carina 

 which is best defined in front ; in the present insect the uneven- 

 ness of the prothoracic surface is not quite so ill-defined, and when 

 carefully examined is found to consist of two rather obscure round 

 swellings placed one on either side of the middle line not far 

 behind the front, and of a longitudinal keel which is scarcely 

 evident except in its hinder half. 



A perfectly fresh specimen of the species that I regard as /. 

 inconspicua has the elytra marked as follows: — The darker portion 

 being regarded as the ground colour a dull silvery stripe commences 

 below each shoulder (where it is narrow) and runs (increasing in 

 width all the way) in a slight curve to the suture, — which its front 

 edge meets at a distance from the base of a quarter, and its hind 

 edge of two-thirds, the length of the suture. From the hinder 

 point where this stripe touches the suture another stripe similarly 

 coloured (narrow at the suture and widening externally) runs 

 across obliquely to a point a little before the apex of the lateral
