410 COLEOPTERA. 
Underside shining black, thickly clothed with depressed flavescent scales 
and coarse greyish setae; metasternum medially impressed ; 5th segment 
broadly rounded at the apex. 
Much narrower than P. dorsalis, the elytral base particularly, their 
punctation less sharply defined, thorax longer, the rostral carina more 
slender, &c. 
Q. Length (rostrum inclusive), 9mm.; breadth, 34 mm. 
Moa Basin. Unique. Obtained from leaf-mould by Mr. T. Hall on the 
20th October, 1913. 
Obs.—In this and some other species the interstitial nodosities near the: 
middle of the elytra are subject to variation : those on the left elytron only 
are described. 
3878. Platyomida hystricula sp. nov. 
Opaque, fusco-piceous, antennae and tarsi fusco-rufous ; densely covered 
with depressed infuscate and tawny squamae, and with longer paler ones 
which are most conspicuous on top of the posterior declivity ; the legs bear 
greyish outstanding setae ; surface rough and uneven. 
Rostrum a third shorter than thorax, slightly dilated anteriorly, its 
slender carina much concealed by the squamae. Eyes slightly prominent. 
Thorax slightly broader than long, more narrowed in front than behind ; 
uneven, with some small obtuse tubercles; the discal channel larger and 
deeper in front than near the base, with broadly raised borders. Elytra 
oblong-oval, almost thrice the length of thorax, scarcely any wider than it 
is at the base, with curvedly narrowed shoulders, their sides with only a 
single but only slightly prominent nodosity, placed behind each shoulder ; 
the declivity narrowed but not usually vertical, with rough scales and 2 
pairs of rather large nodosities; the dorsum appears substriate, but in a 
denuded specimen rather coarse oblong punctures are visible; 3rd inter- 
stices nodiform at the base, binodose near the middle, the terminal nodo- 
sities moderately large but not overhanging the declivity; 5th simple at 
the base, binodose near the middle, not prominent behind. 
Underside, except the bare punctate mesosternum, thickly covered with 
depressed yellowish and paler elongate scales; 5th segment longer than 
3rd and 4th, closely punctured, its apex truncate. 
Scape subclavate at the extremity, attaining the back of the eye; 2nd 
jomt of funiculus slightly longer than Ist, joints 3-7 submoniliform, all 
rather longer than broad. Tibiae flexuous. 
A rather small rough-looking species, distinguishable by the rather large: 
subapical nodosities, the inconspicuous terminations of the 5th interstices, 
and uneven thorax. The scrobes are well developed in front, but there is 
a& squamose space near each eye, and therefore nearly resemble those of 
P. amota (1415). It should be located near P. hamiltoni (3264). 
Length (rostrum inclusive), 73-8 mm.; breadth, 24-34 mm. 
Moa Basin; 20th October, 1913. Four individuals obtained by Mr. T. 
Hall from leaf-mould. 
3879. Platyomida sulcicollis sp. nov. 
Opaque, rather elongate; piceous, antennae pitchy-red, tarsi fusco- 
rufous; squamae principally cupreo-fuscous, flavescent or tawny on the 
head and rostrum, the sides of the thorax, and the shoulders, similarly 
pale but more elongate on top of the declivity.
