Suarp—On New Zealand Coleoptera. OTT 
This curious insect may, I believe, be considered as an aberrant member of 
the Quediina. It has, perhaps, more the aspect of a Cafius than of any other 
known genus, but it differs totally therefrom by the structure of the side-piece of 
the prothorax. I have pointed out elsewhere that the essential character by which 
the Quediina are distinguished is that the prosternum is not placed quite at the 
front of the thorax, but leaves the anterior angles free and projecting. This is the 
case in Cafioquedus, though to a slighter extent than in the other genera of the 
group. Looking on the genus as a member of the Quediina, the very peculiar 
form of the prothoracic side-piece, which in front is scarcely at all inflexed, is 
diagnostic : both marginal lines are quite distinct till the front angles are reached, 
and exactly at this point they are joined. 'The other characters throw but little 
light on the affinities, though the general structure is apparently much that of 
Philonthus. The antenne are similar to those of the larger Philonthi; the labrum 
very short, quite divided; the mandibles long and slender, dentate in the middle. 
The ligula is apparently bilobed, but of this I am not quite sure. The labial palpi 
are rather slender, with the terminal joint quite slender, sublinear, a good deal 
longer than the penultimate joint. The penultimate joint of the maxillary palpi 
is broader at the apex than at the base; the terminal joint of very slender oval 
form, slightly shorter than the penultimate. The middle coxe are slightly 
separated. 
Cafioquedus gularis, n. sp.—Elongatus, subcylindricus, niger, parce albido- 
pruinosus, capite subtus gula sanguinea; prothorace transversim fortiter convexo 
angulis anterioribus per-deflexis ; elytris thorace longioribus, obsolete sculpturatis, 
opacis. Long. 15 m.m. (Plate xu, fig. 13.) 
Antennz black, moderately slender; third joint longer than second; joints 
4—10 each minutely red at the base, the penultimate 3 or 4 joints each slender at 
the base, the penultimate not so long as its greatest width; terminal joint short, 
strongly obliquely sinuate. Head rather elongate, eyes rather large, sides for 
some distance behind them almost straight, then distinctly narrowed to the broad 
neck ; along the inner margin of the eyes is a series of coarse punctures, and be- 
tween this series and the neck are some other coarse punctures, marking off a 
rather large space about the hind angles on each side, which is finely punctate, 
and bears a scanty white pubescence. Thorax rather long, black, shining, and 
impunctate, except that there is a space along each side dull, obsoletely punc- 
tate, and bearing some white pubescence. Scutellum elongate. Hind body rather 
closely and finely punctate, with scanty white pubescence. Underside of head 
and neck red; at each side behind the eye there is a dull punctate space bearing 
white hairs. Legs black, griseo-pubescent. Underside of hind body rather ob- 
soletely punctate, with some coarse numerous punctures irregularly placed on 
each segment. The male has a deep incision on the last ventral plate, and an
