Coleoptera from New Zealand. 427 



punctured ; the frontal impressions large and rather deep, so 

 that the margins over the antennal insertion appear raised. 

 Eyes prominent. Antenna? with fine outstanding setae ; first 

 joint stout; second rather small, not much longer than broad, 

 oviform ; third longer than the second ; fourth and fifth 

 oviform, slightly longer than broad ; 6 to 10 incrassate, sixth 

 and seventh subrotundate, 8 to 10 transverse, eleventh larger 

 than tenth. Thorax subcordate, about as long as it is broad, 

 much narrowed behind, basal angles not prominent ; it is 

 rather more distinctly punctured than the head ; the two 

 dorsal impressions are deep, especially behind, and are rather 

 distant from the base; there is a distinct impression at each 

 side. Elytra less than twice the length of the thorax, 

 gradually narrowed towards the base; their punctuation 

 rather fine, not close nor serial, and becoming more indistinct 

 near the apices ; behind the base there is a slight transverse 

 impression and there is another alongside the suture on each. 

 Hind body quite as long and broad as the elytra, finely sculp- 

 tured, with conspicuous pubescence. The basal joints of the 

 tarsi are half the entire length. 



0. sagoloide, Sharp, is undoubtedly the nearest ally, but 

 this species has no basal callosities on the elytra, and the 

 suture, owing to the longitudinal impressions, appears 

 elevated.

West Plains, Invercargill. One example from Mr. Philpott. 



Omalium Philpotti, sp. n. 



Subparallel, elongate, moderately shining; fusco-castaneous, 

 the hind portion of the elytra darker than the basal ; legs 

 testaceous ; the basal five joints of the antenna? red, remaining 

 joints fuscous and opaque. 



.Read rather finely and not at all closely punctured, inter- 

 ocular fovea? small, frontal impressions shallow. Thorax 

 rather small, transverse, its sides moderately rounded, nar- 

 rowed behind, posterior angles i-ectangular ; discoidal impres- 

 sions broad, shallow in front ; the lateral fossa? indistinct ; its 

 punctuation more distinct than that of the head, but not 

 closer. Elytra about a third longer than broad, closely and 

 rather finely punctate. Hind body as long as the wing- 

 covers, finely sculptured ; apical segment testaceous. 



Underside reddish chestnut, finely punctured and pubescent. 



0. australe has the thorax much more contracted behind 

 and the elytra distinctly narrowed towards the base. 0. fusci- 

 ventre has a cordiform thorax with well-marked lateral fovea?, 

 which this species has not. 0. perplexum is larger and alto- 



gether different.
