Snarp—On New Zealand Coleoptera. 381 
broad. Head narrower than the thorax, with prominent eyes, coarsely and closely 
sculptured, the clypeus with only a few punctures. Thorax much narrower than 
the elytra, nearly as long as broad; front and hind margins straight; sides curved, 
slightly sinuate behind; hind angles rectangular, sharply marked; the surface is 
closely, deeply, and coarsely punctate, has a large impression on each side, two 
indistinct impressions at the base, and another on the middle. The elytra are 
much longer than the thorax, each traversed by about eight raised lines, those 
near the suture coarser than those external; the intervals between the lines sculp- 
tured in a rather indefinite, elongate manner. The male has the fourth and fifth 
joints of the antennz dilated ; an elevated tubercle at the sutural and apical angles 
of the wing-cases, a depression on each of the three basal dorsal serments, and a 
sharply elevated sub-hamate carina on the penultimate segment. 
Greymouth. Helms, one pair. 
OMALIUM. 
Omalium sagoloide, n. sp.—Haud latum, anterius angustior, rufo-testaceum, 
capite thoraceque fuscescentibus, minus breviter pubescens; capite thoraceque 
inzequalibus, profundius impressis, hoc minus fortiter transverso, posterius fortiter 
constricto; elytris minus punctatis, basi ineequale. Long. 2}m.m. (Plate xu, fig. 15.) 
Antennz longer than head and thorax, strongly pubescent; joints 6—10 evi- 
dently broader than those preceding ; penultimate slightly transverse. Head with 
the two frontal impressions deep and large. Thorax rather coarsely punctured, 
with two very deep impressions on the middle, and another at each side. Elytra 
about twice as long as the thorax, rather sparingly punctate, the punctures towards 
the apex obsolete, shining, strongly pubescent, with a transverse depression near 
the base, giving rise to the appearance of a slight callosity on each side of the 
scutellum. 
This species is remarkable from its great resemblance to the more elongate of 
the species of the genus Sagola. It is allied to O. hirtellum Fauy. in litt., but is 
readily distinguished by the more elongate form, less transverse thorax, and more 
uneven surface of the head and thorax.
