punctate. Thorax transversely quadrate, its sides distinctly margined, 

 nearly straight, in some examples slightly rotmded, its angles obtuse, base 

 and apex subtrimcate ; its pimctation rather finer than that of the head, 

 not close, and on some parts indistinctly granulate, some specimens with 

 a median linear space nearly smooth. Scutellum large, finely punctate 

 or subgranulate. Elytra suboblong, of about the same width as the thorax 

 at the base, their apices oblique towards the suture, their sides finely mar- 

 ginated and but little curved ; their sculpture finely punctate or granulate 

 according to the point of view. Abdomen with the first exposed segment 

 transverse, the second longer and narrowed posteriorly, and, in male speci- 

 mens, with a very small apical segment. 



Underside moderately shining, dark fuscous, scantily pubescent, finely 

 yet distinctly but not closely punctate. Prosternal process broad, finely 

 grooved laterally, attaining the mesosternum. Coxse nearly equally 

 separated. Metasternum rather shorter than abdomen, medially grooved. 

 Ventral segments unequal, 5th longest, subconical, the basal one rather 

 longer than the 4th, 2nd and 3rd very short. 



Femora moderately dilated, grooved underneath. Tibiae gradually ex- 

 panded towards the extremity, with distinct terminal spines. Tarsi 

 B-jointed, the basal 4 of the anterior dilated and, together, but little longer 

 than the terminal one ; the 4th of the posterior pair small. 



AntenniB rather longer than the head, 11 -articulate, basal joint large, 

 dilated towards the apex, 2nd cylindric, 3i;d slender, slightly longer than 

 2nd, 4-7 short, 8th obconical, slightly broader than 7th ; club large, 3- 

 jointed, but with an additional small, sometimes indistinct, apical ap- 

 pendage. 



Length, 1|— 2 lines ; breadth, J-| line. 



Sunday Island. 



Common in decaying oranges and bananas. 



Obs. — The species are numerous and widely distributed. Another 

 species (C. heniipterus) was found by me in different parts of Auckland. 

 The allied genus Brachypeplus is represented by a species {B. hrevicornis) 

 which I discovered thirty years ago at Tairua, and in January, 1909, I again 

 met with it on trees at Waimarino. 



Group Enopliid^. 

 Necrobia ruficollis, Fab, 



Suboblong, moderately transversely convex, bearing short and elongate 

 outstanding infuscate and yellowish-grey hairs ; shining ; thorax, base of 

 elytra, and legs red ; remainder of elytra and the head blue ; antennse* 

 nigrescent. 



Head as broad as front of thorax, narrowed anteriorly, distinctly and 

 somewhat irregularly punctured. Eyes large, prominent, coarsely faceted. 

 Thorax about a fourth broader than long, widest near the middle, base 

 finely margined and bisinuate, lateral margins minutely crenulate, its angles 

 obtuse ; disc distinctly but not closely punctate, the sides more closely. 

 Elytra oblong, broader than thorax, evidently seriate-punctate, less dis- 

 tinctly at the base, the suture and interstices finely punctured. 



Legs stout, hairy ; femora rather short. Tarsi apparently only 

 4-iointed, the true 4th joint minute, yet discernible between the lobes of 

 the 3rd, the 2nd and 3rd with membranous lamellae underneath, terminal 

 joint elongate ; claws thickened at the base.
