400 Suarp—On New Zealand Coleoptera. 
extremely similar to the corresponding sex of T. feredayi, but has the meso- and 
metasterna between the middle coxz more consolidated, the produced angles of 
the antennz less elongate, the sides of the thorax without constriction, and the 
punctuation of the interstices rather more obsolete. Thus, the four species, T. 
wakefieldi, T. parryi, T. feredayi, and 'T’. leevithorax appear to be valid, though 
the female of T. feredayi is still unknown, and, no doubt, will prove to be difficult 
to distinguish from the smaller individuals of the corresponding sex of T. wakefieldi. 
Thoramus huttoni, n. sp.—Nigricans, parum nitidus; prothorace elongato, 
anterius angustato, crebre subtiliter irregulariter punctato, dorso utrinque area 
impunctata ; elytris subtiliter striatis, interstitiis crebre obsolete punctatis. Long. 
19 m.m. 
Mas., antennis articulis secundo, tertioque brevissimis, 4-10 angulo apicale

This species is readily distinguished from others of the genus by the fine 
prothoracic punctuation ; it also possesses an important structural peculiarity ; the 
sides of the mesosternal cavity being very much shorter in front ; this character is 
so striking that it may prove to be of generic importance ; the metasternum between 
the middle cox is not very well co-adapted with the mesosternal cavity at the 
sides, but in the middle the two are consolidated. 
Dunedin, Professor Hutton; a single example was sent me from this locality in 1879 by the 
eminent naturalist in whose honour I have named it. 
CRYPLOHYPNUS. 
Cryptohypnus thoracicus, Shp.—Mr. Helms has sent me from Greymouth a 
series of this species; some of the examples are only half the size of the typical 
example, and are besides narrower and more parallel, with straighter sides to the 
thorax; these individuals represent, I have little doubt, the male sex, and they 
come so near to C. frontalis that I feel doubtful whether this latter may not prove 
to be only a very sparingly punctate variety of C. thoracicus: it may, however, be 
retained as distinct till further evidence can be obtained to settle the point 
decisively. 
Cryptohypnus pallipes, n. sp.—Niger, antennis fusco-testaceis, basi, palpis 
pedibusque pallide flavis; prothorace magno, conyexo, nitido, angulis posteriori- 
bus elongatis, sat divergentibus, crebrius fere subtiliter punctato, medio canalicu- 
lato; elytris subtiliter striatis, interstitiis subtiliter punctulatis. Long. 11 m.m. 
This is allied to C. thoracicus, but is readily distinguished by the very fine 
sculpture, and the quite pallid femora and base of the antenne; the pubescence is 
short and extremely fine; the thorax is elongate, the length along the middle being 
just equal to the greatest breadth; the sides are a good deal rounded, and there
