Broun. — On the Larva and Pupa of Ceratognathus irroratus. SSI 



vertex, obsoletely punctate in front ; epistome transversal, with five or six 

 transverse impressions ; lahnim narrowed at the base, cihated at apex ; 

 mandibles stout, dentate at the extremity ; the aniennce implanted at the 

 sides near the base of the jaws, tri-articulate, exclusive of the socket, first 

 joint equalling the next two in length, cylindric, the apical almost aciculate ; 

 palpi four-jointed, basal articulation very large, the others decrease ; eyes 

 indicated by a small lunate black spot behind each antenna ; legs rather 

 long and robust, their three joints becoming smaller, the last terminating 

 in a stout claw. 



The three segments bearing the legs are, conjointly, scarcely longer than 

 the eleventh, all are more or less perceptibly impressed from side to side, 

 the anterior thoracic segments being considerably wrinkled and uneven. 

 The spiracles, though present, cannot be distinguished with accuracy. 



Length 6 lines ; breadth 1^ (maximum). 



Pupa. 



Length, 6 lines ; breadth, 2-2|- ; colour, infuscate testaceous. 



Head large, bearing two spine-like protuberances on the vertex, a pair 

 of smaller ones before each eye ; mandibles large, their form not well 

 defined ; the antennae enveloped in a large lunate sac extending backwards 

 to the middle of the prothorax. Prothorax transversal, a little uneven, 

 with incrassated lateral margins ; a sharp protuberant process forms the 

 posterior angle, another is placed rather in front of the middle at each side ; 

 its disc is bi-impressed longitudinally, but obsoletely on the middle, and at 

 each side of the depressions, at base and apex, are placed two tubercle-like 

 spines smaller than those on the head. Mesothorax short, obtusely pointed 

 behind, with two protuberances. Metathorax canaliculate, bi-tuberculate 

 posteriorly. Abdomen composed of eight segments, all finely and irregularly 

 wrinkled ; the basal with a transverse row of six tubercles ; the others 

 armed at each side with a tubercular process having two claw-like spines at 

 the extremity; each bears a transverse row of small tubercles, the apical 

 segment ending in two robust spines. The limbs repose in the usual 

 manner. 



I cut my specimens out of a Coriaria sarmentosa which they had des- 

 troyed. The insect does not, however, restrict itself to that shrub. The 

 imago is described at page 253 of the " Manual of the New Zealand 

 Coleoptera.'*
