Broun. — ColeojJtcroii^ Fainut of the CJuithdw hlanda. 99 



Antennae with some very slender hairs, basal joint concealed above, 

 3rd about as long as 2nd but much more slender, joints 4-6 rather longer 

 than broad, 9th obconical, broader than 7th or 8th ; club abruptly en- 

 larged, its basal joint evidently broader than the apical, which is rotundate. 



Legs with more slender greyish setae than the body ; tibiae flexuous ; 

 the intermediate especially, and strongly produced inwardly at the ex- 

 tremity, the anterior less so, posterior not distinctly mucronate. 



Underside opaque, piceo-rufous, more or less closely granulate, with 

 numerous slender elongate flavescent setae ; 3rd ventral segment as long 

 as the 2nd and more distinctly impressed in the middle ; prosternum bisul- 

 cate between the coxae. 



The strongly mucronate middle tibiae clearly distinguish this species. 

 An immature specimen is almost wholly ferruginous. 



Length, 4-4-|- mm. ; breadth, nearly IJ mm.

Pycnomerus Erickson. Man. N.Z. Coleopt., p. 208. 



62. Pycnomerus mediocris sp. nov. 



Elongate, moderately shining, piceous, elytra sometimes more rufescent, 

 antennae and tarsi pitchy-red. 



Head distinctly punctate, bi-impressed in front. Antennae pubescent, 

 joints 4-9 transverse, terminal joint evidently narrower than the 10th. 

 Thorax slightly longer than broad, widest near the front, gradually narrowed 

 backwards, anterior angles somewhat prominent, the posterior rectangular 

 but not sharply defined ; disc broadly longitudinally impressed, the middle 

 of the impression nearly smooth towards the base ; its punctation 

 moderately close and coarse. Scutellum small. Elytra wider than thorax 

 at the base, twice its length, with obtusely prominent shoulders ; they 

 are deeply punctate-striate ; the punctures are distinctly separated ; only 

 the sutural striae reach the apical margin, which is a little incrassate, 

 elevated, and bent outwards ; the inner three interstices on each elytron 

 are rather thicker than the others ; the suture is bent outwards at the 

 base and is miited to the 3rd interstice. 



Underside piceous, rather coarsely piuictate, each puncture with a 

 minute yellow seta. Metasternum longitudinally impressed behind. Apical 

 ventral segment broadly bifoveate, its basal margin and the middle nearly 

 smooth. 



This belongs to the section comprising species with moderately large eyes 

 and a distinctly divided biarticulate club. It differs from P. longulns in 

 having slightly projecting front angles and different elytra I interstices, &c. 



Length, 3^-4 mm. ; breadth, 1-lJ mm.

63. Bothrideres paynteri sp. nov. 



Elongate, subdepressed, slightly nitid, with a few slender inconspicuous 

 greyish setae ; nigrescent, legs piceous, tarsi and antennae piceo-rufous.
