424 COLEOPTERA. 
3899. Abrotheus placitus sp. nov. 
Elongate, nearly plane above, subopaque; nigro-fuscous, antennae, 
tarsi, and rostral apex fusco-rufous; irregularly clothed with somewhat 
curled, pale testaceous squamae. 
Rostrum nearly nude in front, elsewhere thickly covered with coarse, 
elongate, rough-looking scales, indistinctly crested near the base. Thorax 
a little longer than broad, hardly any wider before the middle than behind ; 
disc almost smooth, with an indistinct central ridge, covered with short 
scales, extending from the front to the elongate basal depression, it is nearly 
bare alongside the ridge, but the sides are covered with coarser curled 
squamae. Elytra twice the length of thorax, widest and unevenly rounded 
behind the posterior femora, gradually narrowed towards the slightly 
incurved base, more narrowed but not vertical behind ; the broad basal 
depression is bordered at each side with a finely squamose ridge, a similarly 
squamose streak extends backwards from each shoulder; on each elytron 
about 10 unequal crests are formed of coarse, bent, setiform scales, the 
intervals are nearly bare; on the basal portion there are some coarse 
punctures, behind these, each elytron is finely bistriate almost to the 
extremity, there are some scales but no distinct crests on the posterior 
declivity. Legs coarsely clothed. 
Basal 2 ventral segments dark fuscous, a little nitid, with a few distant 
minute punctures and short tawny setae. 
Length (rostrum inclusive), 6 mm. ; breadth, 2 mm. 
Waitakerei Range; 26th April, 1914. I am indebted to Mr. A. E. 
Brookes, of Mount Albert, for the specimen he found near the reservoir. 
Halliella gen. nov. 
Body subpyriform, uneven above. Rostrum strongly arched, stout, as 
long as thorax, its basal half rather narrower than the frontal. Scrobes 
median, foveiform, slightly expanded and quite open above. Head short, 
narrowed anteriorly. Eyes small, lateral, nearly flat, oviform, free. Scape 
stout, gradually clavate, attaining the back of the eye. Funiculus 
7-articulate, 2nd joint nearly as long as the Ist, moderately elongate, 
joints 3-6 transversely quadrate, 7th suboblong; club short, ovate, its 
small apical joints indistinct. Thorax as long as broad, base and apex 
truncate, without ocular lobes. Scutellum absent. Elytra oblong-oval, 
truncate at base, hardly at all wider than thorax there. Legs moderately 
elongate ; femora medially incrassate ; tibiae subflexuous, mucronate at 
extremity ; tarsi short, rather broad, basal 2 joints strongly transverse, 
the penultimate sub-bilobed, also broad. 
Prosternum incurved in front, coxae large, prominent and contiguous. 
Middle coxae distinctly, posterior widely separated. Metasternum very 
short, without any perceptible suture between it and the short basal ventral 
segment, the 2nd segment large, oblique towards its sides, angulate and 
medially depressed in front; 3rd and 4th with straight deep sutures, 
exceedingly short, together little more than half the length ef the 5th. 
The serobes are like those of Lithocia and, consequently, very different 
from those of Phrynixus and Styphlotelus. In this last genus, which some- 
what resembles Halliella, there is no sign of any suture between the 1st and 
2nd ventral segments ; the elytra are evidently incurved at the base, thus
