566 COLEOPTERA 



or aciculate. Labrum soldered to the epistome. Antenna frequently 

 inserted near the base of the mandibles in front of the eyes. Pronotum 

 separated from the flanks of the prothorax by acute ridges, or by fine 

 distinct lines ; often spinous, dentate, or crenulate laterally. Anterior 

 coxa strongly transversal, their cotyloid cavities open behind ; tibia of 

 the same pair without oblique inner furrow ; intermediate cotyloid cavi- 

 ties widely open outwardly. The mesonotum without organs of stridula- 

 tion.

Face between the antennae hollowed out ; mandibles shortish, strong, 

 angulated ; trophi prominent, somewhat clubbed at the end ; eyes large, 

 separated both above and below by a rather narrow division ; antenna 

 with the first joint strong, short and thickest at the end, second very 

 small and somewhat cup-shaped, next eight with a spine at the end, 

 third joint the longest, the others gradually shorter, terminal joint blunt- 

 ish at the end, last joints somewhat flattened ; thorax short, transverse, 

 not nearly so wide as the elytra, sides with a strongish spine about the 

 middle, spine angulated at the base ; sides of scutellum nearly parallel, 

 abruptly rounded at the end, a smoothish ridge down the middle ; 

 elytra longish, rounded at the end and narrowest there, margin slightly 

 turned up ; femora with two spines at the end, tibiae with three spines, 

 two shorter on the inside at the end and a longer one on the outside. 



991. P. reticulariS, White; Voy. Er. Terr., Ins., p. 19. Pitchy- 

 brown, margins of abdominal segments beneath paler ; elytra margined 

 and of a lighter colour, with three longitudinal veins springing from the 

 base and connected by yellowish nervures, forming irregular reticula- 

 tions, not corresponding on each elytron, the elytra have a short spine 

 at the end close to the suture ; the head, thorax, and general surface of 

 the elytra irregularly punctured and vermiculated, thorax covered with 

 many short wool-like hairs, which give it a brownish hue. a longer tuft 

 on each side behind.

I have found a few examples at Tairua and Whangarei, and believe 

 it occurs throughout New Zealand ; as I was fortunate enough to find 

 some of the larvae and pupae in a log at Whangarei, I have given a full 

 description of them in volume xi. of the Transactions of the New Zea- 

 land Institute.
