Many specimens obtained by Mr. Lea from the rotten 

 cores of logs. All the male specimens examined have the 

 upper-surface concolourous, while other specimens, probably 

 female, have the head and thorax red. The underside is 

 generally reddish often suffused with black as in the allied 

 species of Acthosus. Compared with P. Brevis, Carter, this 

 species is much smaller and more convex (especially as to 

 the thorax), the surface is more varnished, the elytral striae 

 less marked, with the seriate punctures more widely separated. 

 Types, I. 2210, in the South Australian Museum. 



Encyalesthus tuberculiceps, n. sp. 



Elongate-parallel ; dull-black above, niticl beneath, an- 

 tennae and tarsi red, tibiae piceous. 



Head with forehead strongly and closely, the epistoma 

 more lightly, punctate ; the suture arcuate and deeply im- 

 pressed, the eyes bordered on the inside by a shining carina 

 raised behind into a blunt compressed tubercle • antennae short, 

 stout, not extending to base of prothorax, the last four joints 

 considerably enlarged, 3 about as long as 1 and 2 combined, 

 4-7 much shorter than 3, subconic, 8-10 much wider than 7, 

 cup-shaped and successively wider, 11 wider and longer than 

 10, squarely rounded. Prothorax 3x4 mm., bisinuate at base 

 and apex, very little wider at base than at apex, faintly 

 produced in the middle in front, the anterior angles obtuse, 

 depressed and slightly rounded, sides feebly converging in 

 front, thence nearly straight to the sharply rectangular pos- 

 terior angles, lateral border narrowly carinate and sulcate 

 within, a narrow sulcus also at the base near sides, apex with- 

 out border; disc rather convex, moderately closely covered 

 with round shallow punctures. Scutellum widely triangular 

 with rounded sides. Elytra, wider than the prothorax and 

 nearly four times as long, subcylindric, seriate-punctate ; each 

 with nine rows of rather large deep punctures (larger than in 

 E. punctipennis, Pasc), besides a short scutellary, and a 

 marginal row, the latter merging into the ninth row about 

 half-way. The punctures becoming larger from base to apex; 

 intervals impunctate, flat near base, becoming convex near 

 apex, the rows sulcate in this region ; margins very narrow 

 and unseen from above. Prosternum, sides of metasternum, 

 and basal segments of abdomen coarsely and sparsely punc- 

 tured, apical segment closely and more finely so ; epipleurae 

 smooth. Tibiae straight, slightly enlarged at apex, basal- 

 joint of hind tarsi shorter than the second and third combined. 

 Dimensions— -16 x 5*5 mm.
