and with smaller punctures interspersed, apex with crowded 

 punctures, elsewhere with small ones divided into well-defined 

 areas by shining lines. Fifth segment of abdomen incurved 

 to middle of apex, feebly depressed across middle. Legs stout ; 

 tibiae strongly ridged, apex of each triangularly inflated, 

 front pair notched at outer apex; basal joint of four front 

 tarsi strongly dilated. Length, 4-4|- mm. 



9 • Differs in having abdomen more strongly convex, 

 legs thinner, and basal joint of four front tarsi much smaller. 



Hab. — Western Australia: Swan River (Blackburn's 

 collection and A. M. Lea). Type, I. 3567. 



The elytra have a conspicuously striped appearance, but 

 the smooth spaces are not elevated as on suhcostatus; it also 

 differs from that species in being smaller, narrower, more 

 convex, and more ovate, punctures much smaller, and tibiae 

 more dilated. In some respects it is close to compositus, but is 

 decidedly narrower, and the tibiae are different. From one 

 jDoint of view the front tibiae appear much as in the figure 

 of that of the following species, but from others the notch is 

 very evident, but on that species from no direction does it 

 appear deeply notched at apex. The first six joints of antennae 

 (wholly or in part), basal joints of palpi, tibiae, and parts of 

 femora and of tarsi are reddish. The punctures on the head 

 are sometimes almost evenly distributed, except that beliind 

 the eyes they are usually somewhat confluent, and denser than 

 elsewhere, but on many specimens they are sparser and smaller 

 about the middle towards the base than elsewhere ; the median 

 impression is usually shallow, but on one specimen is fairly 

 deep. The sides of the elytra are scarcely visibly pubescent 

 posteriorly; each elytron has three distinct oblique lines, im- 

 punctate or almost so; adjacent to them the punctures are 

 more or less seriate in arrangement, with smaller scattered 

 ones between the row^s ; towards the sides, however, the punc- 

 tures are denser; the base, sides, and a^pex are shagreened.

9 . Brassy or bronzy, parts of antennae obscurely red- 

 dish. 



Head evenly convex, without a median impression ; with 

 rather dense and small punctures, more crowded in front and 

 behind eyes than elsewhere. Second joint of antennae dis- 

 tinctly longer than third. Prothorax and elytra much as on 

 preceding species, except that the punctures are slightly 

 denser and on the elytra rather more sharply defined. Tibiae 

 distinctly ridged, the four hind ones triangularly dilated at 

 outer apex.
