82 t)r. Malcolm Cameron on 



Allied to O. leucocnemis, Kr., but much smaller and narrower, 

 more depressed and with shorter head, the posterior angles of which 

 arc much less broadly rounded, differently coloured legs, and the 

 thorax much more narrowed behind. Head quadrate, temples 

 parallel, the posterior angles briefly rounded, the median sulci very 

 short and broad, foveate, the orbital sulci short and oblique; 

 punctures very few, line, and scattered, four rather larger ones 

 placed quadrately on the vertex; ground-sculpture scarcely per- 

 ceptible, strigose. Antennae short and stout, the 2nd joint not 

 much longer than broad, the 3rd to 10th transverse, the pen- 

 ultimate ones strongly so. Thorax scarcely broader than the head, 

 distinctly longer than broad, the sides contracted in a straight line 

 posteriorly from the obtusely rounded anterior angles; the disc 

 on either side with an irregular series of six small punctures, and 

 externally with a curved row of four still liner ones; ground- 

 sculpture as on the head. Scutellum quadripunctate. Elytra as 

 long and as broad as the thorax, parallel, often more or less brownish 

 near the sutural and apical margins; exceedingly finely and spar- 

 ingly punctured ; suture imbricate. Abdomen shining, exceedingly 

 finely and sparingly punctured; pubescence yellowish, rather 

 coarse and sparing. 



$( ?). Sixth ventral segment obtusely produced posteriorly and 

 feebly sinuate on either side. 



Hah. Keppel Harbour, a single specimen in debris. 

 Woodlands, under bark. 



34. Somoleptus linearis, n. sp. 



Shining, head and abdomen black, thorax and elytra pitchy- 

 brown; antennae, mouth-parts and legs testaceous. Length 3 mm. 



A smaller and narrower insect than S. parvulus, Sharp. Head 

 black, wider than the thorax, longer than broad; temples almost 

 parallel, very slightly widened towards the posterior angles, which 

 are rather broadly rounded; eyes much shorter than the temples; 

 base truncate, neck slender, about one-fourth the breadth of the 

 head ; frontal furrows parallel, not well marked, the lateral wanting, 

 the orbital linear, oblique, passing backwards and inwards towards 

 the middle line; punct urat ion moderately close and fine on the 

 temples, rather coarser in front behind the furrows, the middle of 

 the disc impunctate; no visible ground-sculpture. Antennae short 

 and stout, the 1st joint long and thick, the 2nd about one-fourth 

 the length of the 1st, the .">nl to the LOth transverse, increasing in 

 width, the penultimate ones nearly discoidal, Nth short, conical.
