426 Capt. T. Broun on new 



Group Omaliidse. 



Omalium fusciventre, sp. n. 



Elongate, subparallel, shining, sparingly clothed with short, 

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

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

 and antenna? 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. Eyes moderate, but little convex. 

 Antenna? 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 sui'face 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 body 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 enlarged joints 

 of the antennas 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. 



Body rather broad, narrowed anteriorly ; pubescence 

 yellowish, moderately elongate, conspicuous behind; on the 

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

 head and thorax red, darker than the elytra and antenna? ; 

 hind body rufo-castaneous ; legs testaceous. 



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