OF NEW ZEALAND. 99 



outer angles, the last pilose. Legs yellowish ; front tibicc finely ciliated, 

 the others simple ; the basal joint of the posterior tarsi disproportionally 

 elongated, being almost twice the length of the second. 



I possess two examples of a varietal iform, having precisely similar 

 markings to the above, but all the parts much darker in colour ; the 

 elytra and abdomen, for example, being smoky-brown, the former having 

 two more or less apparent basal spots of a reddish colour, and the basal 

 joint of the hind tarsus somewhat less elongated. 



The long slender antenntB, elongate basal joint of the posterior 

 tarsi, and short prothorax, will distinguish this species. 



Length, 2|— 2| lines ; breadth, i-§. 



I obtained four specimens in the Auckland district. 



182. 0. acerbus, n.s. Antenna with three quite yellow basal 

 joints, the fourth somewhat infuscate, sometimes yellow ; the others 

 obconical, fuscous, with the apex of each joint paler. 



Head testaceous-red, shining, sparsely punctulate and pubescent. 

 Prothorax glossy, reddish in front, brown elsewhere ; finely punctulate 

 and clothed with fine yellowish hairs. Elytra longer than the pro- 

 thorax, with clothing similar to that of the thorax, and of nearly the 

 same colour; its sculpture consists, seemingly, of fine linear impressions 

 intersected by transverse lines. Abdomen rather shining, chestnut red, 

 punctulate, and pubescent, and more or less fringed with black hairs. 

 Legs reddish-testaceous ; the anterior tibice finely ciliated, the others 

 simple {id est, not spinous externally, the intermediate are invariably 

 flexuose) ; the lower extremity of the middle femora is rather strongly 

 ciliated with spine-like hairs ; tarsi yellow. 



Its nearest ally is, perhaps, C. largulus, so far as form and colour 

 are concerned, but the present species is much less robust, more glossy, 

 and easily enough identified by the peculiarity of the intermediate 

 thighs. 



Length, 2 lines ; breadth, quite %. 



I found my two specimens near Parua. 



183. C. atricapillus, n.s. Antcnmc robust, rather short; the 

 four basal and the last joints yellow, the last, however, somewhat infus- 

 cate, these basal joints are elongate ; joints five to ten are dull brown ; 

 seven to ten quite transverse. Head shining red, punctulate and pubes- 

 cent. Prothorax glossy, castaneous or infuscate red, with a blackish 

 spot near each posterior angle; punctulate and finely pilose. Elytra 

 rather longer than the prothorax, much more closely sculptured, dark 

 behind, with their yellowish pubescence somewhat concentrated near 

 the base. Abdomen blackish, the apex of each segment, as well as 

 nearly the whole of the last two, of a bright chestnut colour ; some 

 yellowish pubescence can be perceived, and, in addition, all but the 

 two basal segments bear long, erect, black hairs. Legs reddish-tes- 

 taceous. 



Easily recognized by its coarsely pilose hind-body. 



Length, 2 lines; breadth, \. 



I found two individuals at Parua.
