Coleoptera frovi Neir Zealand. 417 



Group Scolytidae. 

 Acrantus opacus, sp. u. 



Cylivdricy subopaque, fuscous ; head nigrescent ; the legs, 

 coxa>, and antenna^ pale ferruginous, club dark ; densely 

 clothed, the thorax -with small, round, depressed brown and 

 brassy scales and short erect slender setae ; on the elytra the 

 squaniosity is similarly variegated but less decumbent and the 

 erect setae are rather paler and more conspicuous. 



Head minutely sculptured, with some yellow hairs in front. 

 Thorax hardly longer than broad, narrowed and slightly con- 

 stricted in front, with some yellow pubescence at the middle 

 of the base ; it is closely punctate. Elytra individually 

 rounded and minutely crenulate at the base ; striate, inter- 

 stices plane ; the external stria are distinctly punctured. Legs 

 finely pubescent ; tibice expanded towards the extremity, with 

 three or four denticles along each of them. Tarsi slender, 

 the terminal joint as long as the basal three; claws well 

 developed. 



Antenna moderately elongate ; scape elongate, very gradu- 

 ally incrassate ; funiculus short, much more slender than the 

 scape, its first joint stout, longer than broad, the following 

 five transverse and provided with very long outstanding 

 slender hairs ; club elongate, opaque, indistinctly four- 

 jointed ; it is rather narrow, and equals the funiculus in 

 length. 



Underside with fine pale pubescence ; the mesosternum 

 with minute squamae, ^fetasternum longitudinally grooved 

 along the middle. First ventral segment large, 2 to 4 short, 

 fifth with a broad basal suture. 



A considerable amount of individual variation occurs. In 

 one the legs are fuscous, in others tiie clothing of the thorax 

 is of a dark uniform colour and consists of hairs, and the 

 antennee are quite short, with an ovate club ; in these 

 examples (probably females) the remarkable villosity of the 

 antennae seems wanting. 



Length 1^, Ijreadth quite f line.

Group AnthribidaB. 



Anthribus JlavipiluSf sp. n. 



Suhcylindri'c ; the dark ground-colour concealed by the 

 clothing; this is hair-like, depressed, and greyish yellow on 

 the thorax, but brighter on the elytra; these latter are varie- 

 gated with grey patches, as in A. vates.
