OF NEW ZEALAND. 1165 



closely punctured, less so behind. Antenna longer than the head 

 and thorax, stout, ninth and tenth joints transverse. Tibia with a 

 short apical process. 



Length, ; breadth, f line. 



Howick. Two specimens. 



Group-ANTHICID^E . 



Cotes. 



2067. C. Optima, n.s. Elongate, rather glossy ; head aeneo- 

 fuscous, thorax more 'rufescent, elytra pale-brown, legs pale-testa- 

 ceous, antennae reddish. 



Head as broad as thorax, much narrowed, but not abruptly 

 truncate, behind ; finely and distantly punctured. Antenna stout, 

 reaching backwards to intermediate femora ; second joint almost as 

 long as third. Thorax longer than broad, constricted behind the 

 middle ; its punctation closer than that of the head, almost dense 

 near the front and base ; its yellow pubescence most conspicuous 

 behind. Elytra widest before the middle, convex, densely covered 

 with depressed fulvous hairs, intermingled with some upright ones 

 which are most obvious behind ; distinctly but not coarsely punc- 

 tured, the punctuation, however, becoming obsolete behind the 

 middle. Legs stout. 



C. vestita is described as opaque, with the head and thorax im- 

 punctate. 



C. proba differs from the present species in having the coarser 

 punctures on the basal portion of the elytra disposed almost in rows. 

 The form of the hind-body is different, being broadest at the middle, 

 in one example probably a sexual variety even after the middle ; 

 the elytra are not convex, or only a trifle so, and are, moreover, 

 depressed behind the base. C. crispi and C. punctata are altogether 

 different insects. 



Length, 3f lines ; breadth, nearly 1 line. 



Howick. One individual, found underneath a log. 



2068. C. punctata, n.s. Elongate, moderately shining, densely 

 covered with depressed and erect yellow hairs, those on head and 

 thorax much' more scanty ; head, thorax, and antennae reddish ; 

 elytra fulvous, but with the basal and middle portions more or less 

 infuscate ; legs and palpi fulvescent. 



Head rounded behind the eyes, as broad as thorax, quite obso- 

 letely and remotely punctured ; the neck broad and coarsely sculp- 

 tured, as, indeed, is the case with the larger species. Antenna 

 moderate ; second joint distinctly shorter than third. Thorax of 

 normal form, the constriction accompanied by an obvious depression 

 across the surface, this narrowed portion quite evidently punctate. 

 Elytra broadest near the shoulders, which, however, are narrowed, 

 as is usual ; they are a little depressed before the middle, and have 

 several series of punctures which do not extend much beyond the
