new genera and species of HalticiucB. 159 



longitudinal strias. Legs rufo-piceous, four hinder tliiglis 

 stained above with piceous. 



Very nearly allied to A. fulvicollis ; it differs iu the 

 more finely punctured elytra and in the almost entire 

 absence of the longitudinal striae on their surfaces; it also 

 differs in the short scutate carina, this part of the face in 

 the older species being longer and pyrifbrm. 



Arsipoda ccei'uleata. 



Subelongato-ovata, modice convexa, metallico-caerulea, 

 iiitida, subtus cseruleo- nigra, an tennis (basi fulva excepta) 

 nigris; thorace laBvi, vix punctato, basi sulco transverso, 

 utrinque longe ante marginem desinente, instructo; elytris 

 oblongis, infra basin leviter depressis, tenuiter striatim 

 punctatis, punctis in striis confusis dispositis. 



Long, 1| lin. 



Hab. — Western Australia (Duboulay). 



Vertex smooth and shining, impunctate ; front im- 

 pressed on either side, above the encarpse, with several 

 deep fove^e; encarpte well defined, transverse, subpyriform, 

 nearly contiguous; carina rhomboidal, extended anteriorly 

 to the front edge of the clypeus ; antenna more than half 

 the length of the body, four lower joints fulvous, stained 

 with piceous, the rest black. Thorax two-thirds broader 

 than long ; sides rounded, scarcely converging in front, 

 the hinder angle produced into an -acute tooth, the anterior 

 one thickened, subacute ; upper surface convex, rather 

 sparingly impressed with minute punctures, only visible 

 imder a lens ; basal surface impressed with a broad well 

 defined transverse sulcation, which terminates abruptly on 

 either side, at some distance from the lateral margin ; 

 anterior border of the groove sinuate. Scutellum trigonate. 

 Elytra broader than the thorax, oblong, faintly depressed 

 below the basilar space, finely striate-punctatc, the jDunc- 

 tures irregularly placed on the strias ; interspaces plain, 

 very finely but not closely punctured. Hinder thigh 

 moderately thickened, hinder tibia nearly straight, its 

 outer edge not longitudinally grooved. 



Genus Crepidodera, Chevr.
