SILPHIDAE. 385 



Dift'erentiated from /. spinifer by the rather less convex but more elon- 

 gate body ; the elytra aie quite double the length of the thorax, elongate- 

 cordate, wider iaefore 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, iisually 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 piinctation 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. 



Fern. — 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. 



cJ. Length, 3| mm. ; breadth, 1| mm. 



Mount Dick, Wakatipu ; 10th March, 1914. Found amongst decaying 

 leaves on the ground by Mr. T. Hal] 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 /. spinifer are to a great extent repro- 

 duced, but the body is rather broader, the tibiae of the male are materially 

 different, beiiig like those of the smaller /. fledipes (1908), the antennal 

 structure also difiers, 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 innei- side, incurved below, 

 and bent inwardly near the extremity, nearly straight along the outside 

 but obliquely narrowed towards the inner apex. Anterior and intei mediate 

 tarsi with expanded basal joints, with sponge-like vestiture underneath ; 

 the posterior pair elongate and slender, their basal articulation almo.st as 

 long as the next three together.
