Coleoptera from Neio Zealand. 189 



The bald surface, ten-jointed antennsB, grooved femora, and 

 the remarkable autennal cavities render the recognition of 

 this genus easj. It should be placed near Ckorasus, from 

 which, however, it is quite distinct. 



Archceoglenes costipennis^ sp. n. 



OchraceouSy slightly nitid, the base and sides of the thorax 

 darker ; the anterior angles, however, are paler and semi- 

 transparent. 



Head with coarse shallow punctures, not quite as wide as 

 the front of the thorax, Antennce with short pubescence; 

 second joint quadrate, stout, longer than the exposed part of 

 the first; joints 3 to 8 of equal thickness, transverse, third 

 slightly longer than the following one, ninth very short and 

 broad, tenth obtusely rounded, as broad as the ninth but 

 nearly twice its length. Thorax moderately convex, some- 

 what raised, smooth, and glossy in front of the base ; the 

 punctures before the smooth part are rather coarser and more 

 distant from one another than those near the sides ; the 

 marginal channels are well-marked, the lateral mai-gins are 

 rather thick, entire, and not much rounded, so that the front 

 and base are of about equal breadth ; along the base there is 

 a distinct transverse depression, with a fovea in the middle. 

 Elytra oblong ; the side margins near the shoulders are some- 

 what explanate, the apical margins are well-developed ; they 

 are striate-punctate, the suture is sHghtly raised, outside the 

 third row of punctures on each elytron there is a distinct 

 costa, the interstices beyond this are more or less elevated, tiie 

 alternate ones most distinctly, so that there seem to be three 

 costse on each. Tihioi with fine setee only ; their external 

 apical angle appears to be as distinct as the inner one. 



Underside pale brown, more or less coarsely punctured, the 

 epipleurffi with two series of punctures.

 1890. 



Near Whangarei Harbour I found a specimen about fifteen 

 years ago ; but as it was difficult to manipulate, I thought it 

 better to defer its description until other examples could be 

 obtained. It lives on the ground amongst decaying leaves.
