448 COLEOPTERA. 
Scape flexuous and gradually incrassate ; club elongate, nearly as long 
as the funicle, its 3rd joint hardly as long as its predecessors combined ; 
funiculus as in O. fasciata. 
Anterior femora clavate, the others strongly angulate and spiniform 
below. Tibiae like those of preceding species. 
Similar to O. bicristata (1621), decidedly more elongate, with longer 
antennae, rostrum more distinctly tricarinate, the eyes less rotundate and 
convex, head and thorax darker, the ely ira rather longer and more striate. 
Length (rostrum inclusive), 64mm.; breadth, 13mm. 
Mount Dick. One ce by Mr. T. Hall on a flowering shrub, at 
an altitude of 2,500 ft., on the 10th March, 1914. 
Group CRYPTORHYNCHIDAE. 
3934. Tychanus lunalis sp. nov. Tychanus Pascoe, Man. N.Z. Coleopt., 
p- 498. 
Convex, uneven, opaque: piceous, antennae and tarsi dark rufous ; 
thickly covered with depressed, overlapping, tawny and infuscate squamae, 
those of the latter colour predominate on the after part of the elytra, there 
are also some erect ones on the elevated parts. 
Rostrum stout, subparallel, as long as the thorax, covered with over- 
lapping infuscate scales, apparently coarsely punctate except at the apex, 
which bears only a few short brassy setae. Thorax a third broader than 
long, somewhat abruptly contracted in front ; with a distinct longitudinal 
carina behind, a median pair of distinct crests, one at each side in line with 
these, and a smaller pair at the apex, its punctation invisible. Scutellum 
small. Elytra quite double the length of thorax, of the same width as it 
is at the base, broader behind the posterior femora, narrowed and declivous 
behind ; along the middle rather finely and distantly substriate-punctate ; 
3rd _ interstices with concentrated squamae near the base; on the 5th a 
curved ridge extends inwardly, between this and the suture there are 
3 small crests, these, conjointly, form an interrupted sublunate ridge 
extending from near the shoulder to the middle of the dise ; on the summit 
of the hind slope there is a small dark crest on each of the 3rd, 4th, and 5th 
interstices, and, lower down, a pair of small, pale ones; a few fine, erect, 
black scales can be seen near the base and sides. 
Legs stout and elongate, squamose, femora dentate underneath. Scape 
implanted just before the middle and attaining the front of the eye. Second 
joint of funiculus nearly double the length of the short Ist, joints 4-6 rather 
larger than the short 3rd, the terminal rather broader than the penultimate ; 
club ovate, rather small. 
With the exception of 7’. quadratus (1545), this is the smallest species 
of the genus. It is distinguishable by the antennal structure, the thoracic 
carina, and sublunate elytral ridge. 
Length (rostrum exclusive), 34 mm.; breadth, 2 mm.

rufous; densely covered with depressed, principally fusco-ferruginous
