1 00 COLEOPTERA 



184. C. auricomilS, n.s. Antenna short, robust; their four 

 elongate basal and the two terminal joints yellowish, the intermediate 

 dark- brown ; joints seven to ten transversal. Head shining, reddish, 

 finely punctulate and pubescent. Prothorax shining, castaneous red, 

 with fine, short, yellow hairs; it is blackish along its base, and very 

 finely and indefinitely sculptured. Elytra quite as long as the thorax, 

 similarly coloured, marked, and clothed. Abdomen castaneous, its fifth 

 segment blackish ; the golden pubescence is almost entirely confined to 

 the two basal and the penultimate segments ; the rest is cinereous, with 

 long black hairs along the sides and apex. Legs reddish-testaceous. 



This may be at once separated from the other species, except 

 C. maculosus, by the yellow apical and basal joints of the antennae. 



Length, if ; breadth, nearly J line. 



Parua. 



185. C. nubilus, n.s. Antennce. moderate, their seven apical 

 joints fuscous, the others yellowish ; the fifth joint is longer than broad 

 and obconical, the following become transversal. Head red, shining, 

 rather coarsely punctured near the eyes. Prothorax moderately short, 

 pale castaneous ; with two broad, black, longitudinal lines not attaining 

 the apex, between these apparently smooth, but, towards the sides, 

 quite obviously sculptured. Elytra a good deal longer than the pro- 

 thorax, reddish-chestnut and shining, the scutellar, apical, and lateral 

 spaces blackish ; their clothing and sculpture like those of the thorax, 

 but the short yellow hairs are somewhat congregated and conspicuous 

 behind. Abdomen blackish, the extremity of the segments of a pale 

 castaneous colour, punctulate, with greyish pubescence, and long black 

 hairs on the sides and apex. 



The unusually coarse sculpture along the sides of the body will 

 readily distinguish this species from all the others. 



Length, if; breadth, nearly J line. 



I found the single individual I possess near Parua. 



1 86. C. maculOSUS, n.s. Antennae stout, their two last and four 

 first joints yellowish, the latter with some rather long hairs. Head 

 almost smooth, shining black. Prothorax yellowish, with two black 

 basal spots ; it is shining, finely sculptured and pubescent. Elytra as 

 long as the prothorax, variegate ; there are two large, irregularly formed, 

 yellowish spots at the base, one near each shoulder, another near each 

 hind angle, the suture is more or less rufescent, and the rest of the 

 surface is occupied by dark-brown flexuose marks. Abdomen castaneous, 

 pubescent, with many long black hairs along the sides and on the apical 

 segment. Legs testaceous-yellow. 



This insect, owing to the colour of the antennae, may be confounded 

 with C. auricomus, but may be easily identified by its shining-black head.

I have several specimens in my collection, chiefly obtained near 

 Whangarei Harbour.
