SILPHIDAE. 385 
Differentiated from I. spinifer by the rather less convex but more elon- 
gate body ; the elytra are quite double the length of the thorax, elongate- 
cordate, wider before the middle than at the base, very gradually narrowed 
posteriorly ; the legs and antennae, moreover, are materially different. 
Antennae longer, basal joint cylindric, rather longer than the elongate 
2nd, 3rd evidently longer than broad, 4th and 5th about equal, rather 
longer than broad; 6th and 7th subquadrate, the latter the larger, 8th 
transverse yet distinctly narrower than adjoining ones, 9th and 10th trans- 
versely quadrate, terminal unsymmetrical, usually prominent at the outer 
extremity. 
Legs more elongate, anterior tibiae straight inwardly, curved outwardly, 
the others not quite straight along the inside, somewhat curved and dilated 
below the middle and, instead of being oblique near the extremity, they 
are curvedly narrowed and slightly bent inwardly, the hind pair are 
minutely serrate. 
Underside evidently pubescent, its punctation distinct but not deep. 
Basal segment with its hind suture obliterated in the middle, 2nd slightly 
longer than 3rd or 4th, the next longer than 4th, 6th apparently depressed 
and emarginate in the middle at the apex, the terminal present but 
rendered indefinite by the pubescence and sappy matter. 
Fem.—Slightly shorter; tibiae straight along the inside, slightly and 
gradually expanded. Abdomen with 6 segments, the 5th distinctly longer 
than 4th, 6th short, rounded behind and on a lower level. 
$. Length, 3 mm.; breadth, 1} mm. 
Mount Dick, Wakatipu; 10th March, 1914. Found amongst decaying 
leaves on the ground by Mr. T. Hall at an elevation of 1,100 ft. Four 
individuals. 
3838. Inocatops separatus sp. nov. 
Oblong-oval, moderately convex, shining; castaneo-rufous, tarsi and 
palpi fulvescent ; with numerous elongate, conspicuous, more or less erect 
yellow hairs. 
In this species the characters of J. spinefer are to a great extent repro- 
duced, but the body is rather broader, the tibiae of the male are materially 
different, being like those of the smaller J. flectipes (1908), the antennal 
structure also differs, and, moreover, the spiniform process of the 2nd 
ventral segment is altogether absent. 
Antennae stout, basal joint cylindric and as long as the elongate 2nd, 
the next twice as long as broad, 4th and 5th oblong, 6th smaller than 
contiguous ones, 8th transverse, as broad as the 7th but shorter; 9th and 
10th large, about equal, both transversely quadrate; 11th unsymmetrical, 
sometimes appearing conical, generally most prominent at the outer part 
of the apex. 
Anterior tibiae slightly arched externally, straight inwardly; inter- 
mediate pair nearly straight inside, gradually dilated outwardly to below 
the middle, obliquely narrowed towards the slender inner extremity ; the 
posterior a little dilated at the middle of the inner side, incurved below, 
and bent inwardly near the extremity, nearly straight along the outside 
but obliquely narrowed towards the inner apex. Anterior and intermediate 
tarsi with expanded basal joints, with sponge-like vestiture underneath ; 
the posterior pair elongate and slender, their basal articulation almost as 
long as the next three together.
