Suarp.—On the Colydiidæ of New Zealand. 391 
Species are eighteen in number ; and in addition to them six previously 
described species are known to me. These are :— 
1. Enarsus bakewellii, Pase. A very distinct and remarkable form. 
2. Bolitophagus antarcticus, White. This species should be referred to 
the genus Ulonotus, Er.; with this latter name Pristoderus, Hope, is, 
according to Mr. Pascoe, synonymous ; but Mr. Hope’s name may be with 
advantage dropped into oblivion, as it has not been accompanied with any 
characters by which it can be recognized, and its place in classification was 
erroneously indicated. 
3. Tarphiomimetes viridipicta, Woll. This is closely allied to, and con- 
generic with, Ulonotus brouni here described, and should be classed with it 
and Bolitophagus antarcticus in the genus Ulonotus; concerning which name 
I may here remark that the characters with which it was associated by 
Erichson were but insufficient, and no species was described ; so that I 
should have almost preferred to use Mr. Wollaston’s Tarphiomimetes had it 
not been objectionably polysyllabie. 
4. Tarphiomimetes lawsoni, Woll. This species may also be at present 
classed in the genus Ulonotus, though it is aberrant from the sides of the 
thorax being without notches. 
5. Tarphiomimus indentatus, Woll. With this Eetomida lacerata, Pasce., 
is specifically identical, as I judge both from the descriptions and from 
information received from Mr. Pascoe. 
6. Bitoma insularis, White, which is at present correctly associated with 
the generic name given to it by White. 
I have included in the eighteen species I have described a very 
interesting insect allied to Aglycyderes setifer, West. Though Aglycyderes 
has not yet been referred to the Colydiide, it appears to me that this may 
at present be done with advantage. 
Thus the number of species of Colydiide at present known to me from 
New Zealand is twenty-four. This number, though large, will undoubtedly 
be much increased (more than doubled I have no doubt, and highly pro- 
bably even quadrupled) ; and it is pretty certain that, like the Atlantic 
islands, New Zealand will prove to be very rich in species closely allied to 
Tarphius ; the genus Syncalus, indeed, here described, is especially close to 
the European and Atlantic Tarphius. I anticipate that some very interesting 
comparisons will be suggested when the New Zealand forms of the family 
are better known, as I hope may soon be the case. 
The Colydiide form one of the less specialized of the Coleopterus families, 
Many species appear to feed on the woody tissue of phanerogamie plants, 
others on dry cryptogamic products, while others, again, are found amongst 
much-decayed leaves and woody matter in dark woods. Other species, on
