distinctly so; the metasternum is not elongate, but is longer than the first ventral 
segment ; this is rather more prominent than the other segments, which are very 
short, with the exception of the last. The front tibiz are slender, armed at the 
apex externally with a curved mucro, internally with a sharp denticle; the middle 
tibize are armed externally with an emarginate prolongation, the lower angle of 
which is quite spinose, and the hind tibiz have a similar termination. All the 
tarsi are very slender, the third joint being not thicker than the others, and not 
bilobed. 
T have little doubt the insect thus characterized is the genus described under the name of Stenopus 
by Broun, Man. New Zealand Coleoptera, Pt. u., p. 789, and afterwards re-named Inosomus. Broun 
placed the genus in Scolytide, alluding to its resemblance with Cossonide, however ; but the possession 
of a true rostrum and slender anterior tibie, not denticulate externally, are characters that require it to 
be placed at present among the Cossonide. In Broun’s description of the species Stenopus rufo-piceus 
an unfortunate error occurs; the first line on p. 740, instead of ‘seven interstices are a little elevated 
behind, are merged,” should read, ‘‘ seventh interstice is a little elevated behind and merged.’ This 
insect was found by Helms at Picton. 
Fam. ANTHRIBID 2. 
ANTHRIBUS. 
Anthribus tuberosus, n. sp.—Nigricans, dense vestitus, rostro elytrorumque 
lateribus griseo-ochraceis, antennis pedibusque testaceis, his conspicue maculatis ; 
elytris tuberculis grossis ornatis. Long. 4; m.m. (Plate xur., fig. 18.) 
This species does not appear to be very closely allied to any other, but may be 
placed near A. discedens. It can be readily distinguished by the very large basal 
tubercles of the elytra, and the fact that the sides of the wing-cases are covered by 
pallid, the middle by dark, pubescence. Antennze not so long as the body, yellow; 
first joint covered in front by white pubescence ; second joint very feebly pubescent, 
oval; third much longer than the following, swollen at tip, 6-8 sub-equal, each 
slightly swollen at the tip; ninth as long as the eighth, equal to the two following 
together, and forming with them a well-marked club. Rostrum short and broad, 
densely covered with very pallid griseo-ochraceous pubescence. Eyes convex, only 
moderately large, rather deeply emarginate. Thorax much broader than long, with 
well-marked carina distant from the base, and a little angulate in the middle, bent 
forward at the sides, forming an obtuse angle, and extending one-third of the 
length to the front; the outline of the sides is uneven, and a little narrowed 
towards the front; the surface is black variegate on the middle, with pallid 
pubescence. Elytra with two extremely large centro-basal tubercles, with two 
smaller, but yet large post-median tubercles, and just before the declivity with
