Coleoptera from New Zealand. 167 
towards the base, which, however, exceeds the thorax in 
breadth, they are not punctate apparently; on each elytron 
there are two broad grooves, one near the suture, the other 
along the middle of the disk; the interstices are costiform, 
the outer costa at the shoulder is a good deal thickened, and 
the basal margin appears thick and asperate. Hind body 
rather shorter than the elytra, much narrowed posteriorly, 
but little deflexed, the basal four segments of nearly equal 
length, first and second transversely impressed at the base, 
the depression on the latter not so wide as the other. Tvbie 
evidently expanded towards the extremity. 
Underside castaneo-rufous, sparsely pubescent. Head 
with a few slender outstanding sete. Sront core elongate, 
exserted, and contiguous, placed close to the hind margin of 
‘the prosternum ; the sinuous carina near each side is distinct. 
Mesosternum in the middle with a rather broad lamina; this 
has sharp borders, and it is acutely prominent behind. In- 
termediate coxe only slightly separated, the trochanters short. 
Metasternum convex. Hind coxe but little separated. Abdo- 
men slightly transversely convex, with six nearly equal 
segments ; two to five decrease a little in length, the first is 
covered with yellow pubescence. 
Antenne as long as the head and thorax, red, paler towards 
the extremity, tenth joint infuscate at apex; second joint 
smaller than first, with slightly curved sides; third a little 
longer than broad, narrowed towards its base ; fourth to eighth 
bead-like and differing but little ; ninth quite twice the size of 
the preceding one, narrowed towards the apex, its frontal 
articulation very narrow, so that it is distinctly marked off 
from the following one; tenth strongly transverse, its apex 
closely applied to the eleventh joint, which is narrower, 
conical, and acuminate. 
This, though much like £, elegans, differs in many ways. 
The head is not broader in line with the eyes than it is 
behind ; in Z. elegans it is so much wider near the eyes that 
the sides behind are obliquely narrowed. The eyes are very 
small. The elytral cost, though present in L. elegans, are 
less distinct. ‘The legs of . costifer are shorter and less 
slender. The tenth antennal joint is distinctly shorter. The 
supplementary apical segment is wanting. 
Length 3, breadth } line. 
Mount Pirongia. I found two of uncertain sex, one 
damaged. 
Obs. I found what may be considered a varietal form at 
Ligar’s Bush, Papakura, The head is as broad as the thorax
