 include the following New Zealand species : 



L. vulgaris (No. 1108), Broun. L. sulcifer, Broun. 



L. attenuates (No. 1109), L. rectipes, 



L. thoracicus (No. 1110), L. calcaratus, 



L. nigripes (No. 1111), L. princeps, 



L. nigricans (No. 1112), L. monticola, 



L. nitidicollis (No. 1113), L. fuscatus, 



L. seneus (No. 1114), L. sordidus, 



L. viridis (No. 1115), L. truncatus, 



L. oleareae, L. nigricornis, Sharp. 



L. rugicollis, L. oenescens, 



L. brevicollis, L. puncticollis,

 Nov. gen. 



Luperus is an allied genus ; in facies, indeed, both are much alike ; 

 the two following species possess, however, three or four characters 

 in common which at once differentiate them from Luperus. 



The posterior tibia are curved in a direction just the reverse of 

 that seen in Luperus, they are considerably thickened towards the 

 extremity, and the protuberant and almost cavernose apex is pecu- 

 liar. The basal joint of the hind tarsus is compressed laterally, so 

 that its greatest bulk is from above downwards ; that of the others 

 is a good deal expanded, but flattened above ; the claws are small, 

 and apparently not appendiculate. 



Perhaps the best illustration I can afford as to the structure of 

 the basal articulation of the posterior tarsi is that of No. 1457 (Zeo- 

 pcecilus opulentus), one of the Geodephaga. 



2318. A. nitida, n.s. Glossy, aeneous, legs and first antennal 

 joint testaceous, the other joints darker, the extremity of joints 

 5-11 blackish. 



Thorax broader than long, yet not very transverse, its sides finely 

 margined and but little curved, front angles thickened, posterior 

 obtuse ; the surface slightly uneven, rather finely and distantly 

 punctured. Sciitellum small, smooth. Elytra elongate-oblong, very 

 little distended behind, their apices, individually, strongly rounded ; 

 they bear a few short grey hairs, have a depression near each 

 shoulder, and are rugosely punctate. Pygidium short and broad, 

 nearly smooth. Antenna stout, not very elongate, first joint not 

 much inflated, second shortest, each of the others twice as long as 

 broad. Legs robust ; hind tibiae much arcuate inwardly, and some- 

 what thickened towards the apex ; basal joint of intermediate and 

 anterior tarsi much broader than in Luperus. 



Though resembling Luperus monticola in some respects, it is 

 decidedly narrower. 



Length, If lines ; breadth, $ line. 



I am indebted to Mr. S. W. Fulton, of Outram, for the only 

 specimen I have seen. He found it on Mount Maungatua.
