386 Saarp—On New Zealand Coleoptera. 
This species is very like a small Endophlceus; but, though there is a very 
slight enlargement of the ninth joint of the antennz and the club itself is rather 
slender, yet it is very evidently only two-jointed. The head is remarkably 
strongly elevated at each side over the antennal cavity, and the first joint of the 
antenna is concealed ; the sides of the submentum are quite prominent, and there 
is thus formed a well-marked antennal fovea adjacent to the eye; the legs are short, 
and there is a very slight incrassation of, and prolongation of, the under-surface of 
the basal joint of the tarsus. The form of the thorax is remarkable, the front half 
having the sides dilated as an explanate projection, as in Tarphiominus, while the 
posterior half is not explanate, but merely armed with some elongate denticles or 
serrations ; the surfaces of the head and thorax are rather closely granulate, and 
the latter is a little uneven; the elytra have regular series of punctures, which, 
however, only look like punctures when viewed from one direction, and each 
also has three series of three or four small tubercles, which are a little hispid at 
the summit; near the scutellum at the base is a longer elevation, and the lateral 
margins are minutely serrate and hispid. The tibize are destitute of any but very 
fine clothing.

Bitoma serraticula, n. sp.—Oblonga, angustula, fusco-ferruginea, antennis 
pedibusque rufis; prothorace lateribus minus explanatis, serrato-dentatis; elytris 
regulariter seriatim sculpturatis, hispidulis, guttulis minutis ferrugineis, griseo 
fasciculatis. Long. 35 m.m. 
This is allied to B. auriculata, having a similar structure of the head and legs, 
though the elevations over the antennz are not so large; the sides of the thorax, 
however, are different, owing to the anterior explanation or lobe being here less 
developed. The thorax is rather strongly transverse, the surface a little uneven, 
like the head, closely granulose. The elytra have a very regular serial sculpture, 
consisting of about nine rows of punctures, the punctures being connected by a 
series of five crenate elevations; they are also regularly hispid, and have each 
three series of distinct pallid red, minute spots, the fasciculation of these spots 
being pallid. The legs are short and stout.

Bitoma mundula, n. sp.—Oblonga, angustula, subdepressa, fusco-ferruginea, 
subtiliter squamosa haud hispida, antennis pedibusque rufis ; prothorace lateribus 
anterius lobato-explanatis, posterius constrictis ; elytris tantum ante apicem tuber- 
culatis, apice abruptius declivo. Long. 3 m.m. 
Antenne short, with rather large two-jointed club. Head but little elevated at 
sides over the antenne. Thorax with numerous slight depressions, rendering the
