have three dilated joints, triangular, but eniarginate at the apex, and 

 spongy underneath as well as hispid.

I have seen one only, much mutilated, labelled by Professor 

 Hutton " Invercargill." 



1338- C. ruficorne, n.s. Oblong, somewhat convex, glossy, 

 pitchy-black ; antennae, palpi, and legs infuscate-red. 



Head rather short and broad ; frontal depressions broad, shallow, 

 and finely lineated ; labrurn much reduced, widely incurved ; man- 

 dibles long and stout, arcuated apically ; eyes moderate, not very 

 prominent. Proihorax sub-quadrate, base and apex nearly entire ; 

 sides very little rounded, gradually narrowed till near the posterior 

 angles, where they are straight, or nearly so, the angles rectangular 

 but not projecting ; disc nearly plane, its dorsal groove extending 

 from the hind margin to near the apex, basal foveae elongate, quite 

 sulciform. Elytra oblong-oval, scarcely sinuated apically ; moderately 

 striated, the striae more or less confluent posteriorly, the four sutural 

 only distinctly yet rather finely punctured, interstices simple. Antennas 

 short and stout, their three basal joints glabrous. Palpi robust, 

 terminal articulations of all quite oval and acuminate. Legs stout ; 

 anterior tibiae somewhat dilated, intermediate externally and in- 

 wardly spinose, the posterior inwardly, and arcuated. The stout 

 palpi (maxillary and labial), with their perfectly oval terminal joints 

 pointed at the extremity, distinguish the insect. The mentum is 

 concave, but not apparently dentate. The characters do not cor- 

 respond with those assigned to the genus by Castelnau ; nevertheless 

 I must refer it to Cerabilia until the difficulties connected with the 

 paucity of entomological literature and collections can be sur- 

 mounted.

Mr. P. Stewart- Sandager recently sent me two examples, both 

 females, from Wellington.

Oopterus (p. 54)- 



X 339- O. CarinatUS, n.s. Convex, oblong-oval, moderately 

 glossy, dark-castaneous ; the suture and margins of the elytra 

 rufescent ; legs fulvous ; labrum, palpi, and antennae ferruginous. 



Head sub-trigonal, with a groove close to each eye, and a broad, 

 irregularly-formed one nearer the middle, united to its fellow by 

 means of a curved impression proceeding from the base of each 

 mandible; epistome bi-punctate; labrum truncate. Prothorax 

 longer than broad, sub-oblong, finely marginated, a little nar- 

 rowed anteriorly, behind nearly straight, yet just visibly sinuated 

 before the rectangular, but not at all projecting, hind angles; the 

 median groove is feebly impressed, the basal foveae are large and 

 distant from the sides, and the interval is punctate ; the narrow 

 marginal channel is separated from the basal foveae by a very 

 evident carina extending forwards from the hind edge. Elytra
