656 * COLEOPTERA. 



brotKi band on top of the posterior denlivity arc tawny, thore are also 

 uunuu-oiis erect scale-like setae, some of which form crests. 



Rostrum as long as thorax, arched, moderately stout, very slightly 

 narrowed towards the centre, squamose behind the antennae, punctate in 

 front. Head immersed up to the eyes, bicristate. Thorax a fifth broader 

 than long, widest bc^fore the middle, nearly straight towards the truncate 

 base, distinctly contracted in front ; a little uneven above, moderately 

 coarsely and closely punctate, with a pair of small median crests. Scutel- 

 lum grey. Elytra oblong, almost double the length of thorax, of the same 

 width as it is at the base, with slightly oblique shoulders, a fourth broader 

 near the middle, posterior declivity considerably narrowed but not quite 

 vertical ; they are coarsely striate-punctate near the suture, irregularly 

 towards the sides, obsoletely behind ; third and fifth interstices more or 

 less evidently tricristate above. 



Legs with man}^ erect squamiform setae, some paler than others ; 

 femora unarmed, longer than the tibiae, all of which are uncinate. Tarsi 

 moderately broad, thickly setose, penultimate joint bilobed, rather thicker 

 than preceding ones ; claws small. 



Scape elongate, implanted just before the middle, reaching the eye, 

 rather slender, very gradually incrassate ; basal joint of funiculus moderately 

 stout, scarcely any longer than the next, third longer than fourth or fifth ; 

 sixth and seventh short, the latter as broad as the oblong-oval, triarticulate 

 club. 



Underside blackish, punctate, with greyish squamae. Pectoral canal deep, 

 extending to the middle coxae. Basal ventral segment largest, second as 

 long as the modeiately abbreviated third and fourth combined, fifth broad, 

 rounded behind. When mounted on cardboard, with the rostriim stretched 

 out, an obvious sinuosity is seen at the front side of the thorax behind the 

 eye, and the part below is distinctly rounded ; in this instance, therefore, 

 the ocular lobes are well developed. 



This belongs to the same section as Pascoe's A. intutus (866) and A. aus- 

 tralis (2180), but in the latter the scape is short and inserted behind the 

 middle of the broader rostrum, the thorax is less contracted in front, the 

 elytral inequalities are dissimilar, the funiculus is more slender and differently 

 formed, and the conspicuous interocidar crests are absent. 



Length (rostrum exclusive), 3| mm. ; breadth, 2 mm.

4241. Acalles bicostatus sp. nov. 



Convex, subovate, o])aque ; black, tarsi fusco-rufous, antennae paler : 

 the squamae mostly depressed and dark ashy ; but near each side of the 

 thorax, and indefinitely along the middle, they form a curvate streak of a 

 ta.wny-grey hue, and on the second and third interstices of the elytra and 

 the middle of the posterior declivity they are similarly pallid ; the short, 

 coarse, erect setae are more or less nigrescent, and form two or three small 

 crests on each elytron, and a still sinall(>r, indistinct ])air on the centre of 

 the thorax. 



Rostrum a third shorter than thorax, feebly arched, slightly narrowed 

 towards the middle, irregularly punctate near the sides and in front, 'vith 

 pales scales near the base. Thorax subconical, slightly broader than long, 

 v/idest and obtusely rounded behind the middle, gradually narrowed 

 anteriorly, nearly straight towards the truncate base ; disc without inequali-
