The dorsal surface of this insect is of a livid brown colour, vaguely 

 and irregularly clouded with piceous on the head and disc of the 

 pronotum, and much mottled with small piceous patches on the 

 elytra. The under surface is hrown, more or less clouded with 

 vague infuscation. The male probably has the sides of the pro- 

 notum much less strongly excised behind the middle and the 

 front tibiae bidentate externally, as in A. victoriae, Blackb., and 

 (according to description) in erosus, Er. 

 Victoria (Dividing Range). 



A. INSIGNIOR, sp. nov. 



Oblongus; minus convexus ; minus nitidus supra breviter (in 

 capite pronotoque sat longe) ; setosus ; niger vel nigro-piceus pro- 

 thoracis lateribus elytris pedibusque luteis; capite sparsissime 

 punctulato, antice late sinuatim truncato ; oculis perspicue granu- 

 latis ; prothorace quam longiori ut 4 ad 3 latiori (feminae paullo 

 magis tranverso), supra sparsissime punctulato, longitudinaliter 

 canaliculato, antice parum angustato, lateribus aequaliter modice 

 arcuatis, angulis omnibus obtusis, basi baud marginata ; scutello 

 modico vix punctulato ; elytris punctulato-striatis, interstitiis 

 sat planis (3", 5°, 7°, O^que tuberculis piceis sat fortibus seriatim 

 instructis) ; tibiis posticis transversim bicarinatis, setis inter se 

 diversis vestitis ; tibiis anticis extus maris bidentatis (feminae

Long. 2i 1. Lat. 1 1. 



Resembles A. erosus, Er., and suberosus, Blackb., in having 

 tuberculate elytra, but diffei's from both ititer alia by the hind 

 part of the lateral margin of the prothorax not being excised in 

 the female ; also differs from erosus by its scutellum not being 

 black, and from suberosus by the entirely dissimilar puncturation 

 of the pronotum. The tubercles of the elytra on interstices 3, 5 

 and 7 are considerably better defined than those of A. suberosus, 

 and are on each six or eight in number ; those on the 9th inter- 

 stice are less conspicuous and less numerous.
