426 Capt. T. Broun on new 



Group Omaliidse. 



Omalmm fusciventre, sp. n. 



Elongate, subparallel, shining, sparingly clothed with sliort, 

 rather fine, yellowish hairs ; those on the hind body are, 

 however, rather longer and more easily seen ; head, thorax, 

 and antennte red ; elytra brighter and paler red, but with the 

 suture near the base and the hind part of each side fuscous ; 

 abdomen fuscous, its extremity paler ; legs testaceous. 



Head finely and not very closely punctured, the frontal 

 impressions rather shallow, ^j/es moderate, but little convex. 

 Antennce pubescent, first joint stout and finely sculptured, 

 second little more than half the size of the basal one, longer 

 than broad, oviform ; third longer than broad, rather slender ; 

 fourth and fifth small and bead-like ; 6 to 10 evidently 

 broader than the preceding ones, 8 to 10 transverse, eleventh 

 large. Thorax rather broader than long, its sides distinctly 

 margined and well rounded in front ; behind the middle they 

 are gradually narrowed and nearly straight ; the posterior 

 angles are rectangular but not acute ; its surface is rather 

 more distinctly punctured than the head, the two dorsal 

 impressions are well marked, and there is a fovea-like depres- 

 sion at each side. Elytra oblong, wider than the thorax, 

 slightly narrowed towards the base, their hind angles rounded ; 

 the suture is well defined and rather more elevated behind 

 than in front ; their punctuation is regular and almost serial, 

 but becomes a little less distinct behind. Hind hody of the 

 same width, but rather longer than the elytra, finely sculp- 

 tured, fifth segment longest. Legs simple. Tarsi with the 

 basal joints, taken together, much shorter than the terminal 

 one. 



This most resembles No. 1861 ; the head is more distinctly 

 punctured, the eyes are less convex, and the enlai-ged joints 

 of the antennse are more transverse. No. 1854 also is some- 

 what similar. 



Length 1, breadth $ line. 



West Plains, Invercargill. My specimen was found by 

 Mr. Alfred Philpott. 



Omalium australe, sp. n. 



Bodg rather broad, narrowed anteriorly ; pubescence 

 yellowish, moderately elongate, conspicuous behind; on the 

 sides of the thorax there are some long, slender, erect setse ; 

 head and thorax red, darker than the elytra and antennse ; 

 hind body rufo-castaneous ; legs testaceous. 



Head nearly as large as the thorax, finely but not closely
