108 SUBANTARCTIC ISLANDS OF NEW ZEALAND. [Coleoptera. 



as if transformed into very minute granules ; they are somewhat irregularly sub- 

 striate, and bear numerous very minute yet quite perceptible greyish setae ; the 

 3 elongated elevations on each elytron are here mere swellings of the terminal por- 

 tions of the interstices, the outermost is not sufficiently raised to form a 4th. 



Most nearly resembles P. tuherculntus, but the elytral apices appear more pro- 

 longed, the sculpture of the head and hind-body is quite appreciably finer, the sides 

 of the thorax are less rounded, and there are no distinct serial punctures on the 

 elytra. 



In all three species the surface seems glabrous : in reality all bear very minute 

 inconspicuous setae, which may pass unnoticed ; they are most easily detected on 

 parts that are turned away from the light. The antennae of all bear distinct yellow 

 pubescence on the terminal 4 joints ; the other joints are more or less bare. In 

 P. fosticalis the minute brassy setae along the lower half of the anterior tibiae, in 

 front, are more distinct than in the other species.

Campbell Island. 



A single specimen (Mr. Marriner). 



Pseudhelops interruptus, sp. nov. 



Oblong-oval, convex, nitid ; thorax fusco-cupreous ; elytra somewhat cyaneous, 

 with reddish-coppery specks ; legs and antennae rufescent ; sparingly clothed with 

 minute greyish setae. 



Head fusco-piceous, a little uneven, finely and distantly punctured. Thorax 

 subquadrate, an eighth broader than long, quite as wide at the base as at the middle, 

 the sides between these slightly sinuate, gently curvedly narrowed anteriorly, base 

 bisinuate ; its whole surface densely and very minutely sculptured, the punctuation 

 a little irregular, fine, but not close. Scutellum subquadrate. Elytra oblong-oval, 

 with dense minute sculpture ; they are irregularly striate, moderately deeply at the 

 sides and extremity but shallow near the base and suture, all more or less finely 

 interrupted or flexuous at short intervals ; interstices finely but not closely punc- 

 tured ; 3rd, 5th, and 7th only moderately prominent behind. 



This differs from P. fosticalis as follows : It is rather smaller ; the 2nd, 4th. 

 and 5th joints of the antennae are more elongate and slender ; the apices of the 

 elytra are not prolonged; their striae are deeper but less regular; and the nodo- 

 sities, though smaller, are more definite ; the thoracic margins are finer ; and the 

 coloration is materially different.

Discovered recently by Messrs. W. K. Chambers and F. S. Des Barres. 



Group OTIORHYNCHIDAE. 



Catodryobius, gen. nov. 



Body robust, apparently apterous, subovate, clothed with decumbent slender 

 squamae. 



Rostrum shorter than thorax, moderately dilated, subpterygiate, near the front, 

 without sharply marked triangular clypeal sutures. Mentum truncate at apex, 

 gradually curvedly narrowed towards its base, about as long as it is broad, the
