ARTICLE VI.-DKSCRIPTIONS OF COLKOPTKHA FROM THE SUB- 

 ANTARCTIC ISLANDS OF NEW ZEALAND; 



WITH REMARKS ON THE AFFINITIES OF THE GENERA, ETC. 



By Major T. Broun, F.E.S. 



PLATE V. 



On reference to the following list it will be seen that the Coleoptera now described 

 consist of forty-six species, located in twenty-six genera. 



Two of these genera seem doubtful. One, Blanchard's Pristancylus, so far 

 as can be judged by its description, is synonymous with Pristonychus, which has 

 been long known to occur in Europe, Asia, Algeria, Oceania, and Claili. The second 

 genus, Calathus, is spread over nearly the same regions, but as Baron Chaudoir 

 has stated that Blanchard's C. ruhromarginatus in the male " has four joints of the 

 anterior tarsi dilated and brushlike underneath," and as nothing is said about the 

 denticulated claws, that species may belong to an altogether distinct genus. 



The genera Omalium, Catops, Morychus, Dorytomus, and Acalles are almost 

 cosmopolitan, and are numerously represented in New Zealand, but these southern 

 islands, as yet, have yielded only one species of each. 



Seven genera having been accounted for as more or less of world-wide distri- 

 bution, we may restrict further observations to the remaining nineteen. Mere 

 general allusions, however, will be of little scientific or practical value, so we must 

 consider some at least of the more significant forms more carefully if we wish to learn 

 anything from the collection brought here by the various members of the recent 

 expedition. 



Pseudhelops is nearly related to Helops, the species of which latter are widely 

 scattered, and to Addium, which is tolerably common in Australia and New Zealand, 

 and is said to have been found in Chili and New Caledonia. The four species now 

 brought to light have not been seen beyond Carnley Harbour and Campbell Island.* 



Loxomerus, with five species, is a purely antarctic form, having Miqadops from 

 Tierra del Fuego and the Falkland Islands as its nearest congener, but its species 

 seem to be confined to the Auckland Islands. 



• ADDKMimM. — Since the foregoing was in print I have tlesoribed Pneudhelopn mibstriatut, a new 8()ecie8 found 

 in New Zealand. This discovery is important, as it confirms my views respecting the close affinity of the New 

 Zealand and AuclUaud Islands coleopterous faunae. — Tiios. liiinuN.
