Hab. West Australia. 



Besides the colour, wliicli, however, varies much in intensity, 

 the form of the prothorax, and of the elytra at the base, will at 

 once diiFerentiate this species from the last. 



Alexirhea falsifica. a. oblongo-ovata, nigra, opaca, humeris (in 

 unico spec.) griseo-squamosis ; scapo breviusculo ; prothorace ut in 

 praecedente, sed minus rotundato, canalicula vittaque utrinque griseo- 

 squamosis; elytris subseriatim fortiter foveatis, interstitiis elevatis, 

 irregulariter tuberculatis, cornibus duobus ad suturam supra apicem 

 obsitis, et apice ipso similibus, humeris vix productis, corpore infra 

 nigro-setosulo ; pedibus albo-squamosis, setulis adspersis. Long. 5 

 lin. 

 Hab. Western Australia (Champion Bay). 



The two horn-like projections (contiguous, and therefore appar- 

 ently one) on the suture above the apex of the elytra are peculiar 

 to this species. 



The following table will give an idea of the principal charac- 

 ters of the genera of the long-scaped Amycterinse ; Alexirhea, 

 however, might perhaps have been better placed with the short- 

 scaped genera (" Euomides " of Lacordaire). 



Eostrum (or head) crested (either with tubercles or spines). 



"With ocular lobes Acantliolophiis, Schon. 



Without ocular lobes. 

 Eostrum broad. 



Porehead flat, a transverse suture separating it from the 



rostrum Ciibicorhynchws, Lac. 



Forehead convex and rugose. Syhorhynclius, MacLeay, jun. 

 Eostrum narrow. 



Eyes coarsely faceted .... Anascoptes, n. g. 



Eyes finely faceted Polycreta, n. g. 



Eostrum not crested. 



Male with anal forceps ...... Psalidura, MacLeay. 



Male without anal forceps. 



Scape extending beyond the eye. 



Base of the prothorax closely applied to the elytra. 

 Head and rostrum concave. 



Amycterus, Schon. 

 Head convex. 



Eostrum broad, with two oblique ridges.
