BRONTIDAE. 39 



Group Cerylonidae. 



3087. Philotheripus bicavus Reitter. Gen., Man. N.Z. Coleopt., p. 210. 



Rufo-ferruginous, narrow, subdepressed, shining, elytra at base and apex 

 sometimes bronzed, with fine erect grey hairs. 



Head somewhat narrower than thorax, finely punctate. Thorax rather 

 longer than broad, slightly narrowed towards the base, subcordate, posterior 

 angles acutely rectangular, sparsely and finely punctured, wdth 2 dorsal 

 foveae. Elytra elongate-oval, rather wider than thorax at the base, finely 

 punctate-striate to the apices. 



Length, 2-2-2 mm. 



Greymouth. Mr. R. Helms. 



Group Brontidae. 



3088. Parabrontes rugicollis sp. nov. Gen., Man. N.Z. Coleopt., p. 220. 



Depressed, elongate, slightly nitid, nigro-fuscous : antennae dull dark 

 infuscate red, their basal 3 joints more shining ; legs pale brown ; the 

 femora, extremity of tibiae, and tarsi paler, quite testaceous when alive ; 

 sparingly clothed with fine yellow hairs. 



Head irregularly longitudinally rugose, with some coarse punctures 

 behind ; the forehead and raised antennary orbits nearly smooth ; along- 

 side these latter 2 longitudinal grooves with distinct margins extend towards 

 the base. Thorax about as long as broad, apex slightly rounded, base 

 subtruncate ; at each side, in front, there is a conspicuous angular projection, 

 which is almost smooth and sometimes rufescent ; the sides are broadlv 

 rounded behind the middle, where 3 or 4 minute tubercles or denticles are 

 placed, but near the base they are obliquely narrowed and depressed, and 

 do not form distinct angles : the disc has numerous obvious, irregular, 

 more or less finely punctured rugae, there is scarcely any smooth space on 

 the middle, near the sides the sculpture is distinctly granular. Sciitellum 

 broad. Elytra elongate, subparallel, evidently wider than thorax at the 

 base ; the suture, except at the base and apex, appears slightly elevated, 

 owing to the broad depressions alongside ; on each there are a scutellar and 

 7 series of moderately coarse punctures on the dorsum, which hardly form 

 striae, and become finer near the extremity ; the interstices in line wnth 

 the shoulders are subcarinate. 



Antennae robust, reaching backwards to the hind femora, distinctly 

 pubescent ; basal joint thick, longest ; 2nd small, transverse, and sub- 

 globular ; 3rd nearlv twice the length of the 2nd, but a third shorter than 

 the 4th. 



Underside shining, fuscous, spariiigly and finely pubescent. Prosternum 

 distinctly rugose-punctate, its flanks smooth and marked off by rather deep 

 obhque grooves. Metasternum more finely pmictured. with a median sulcus. 

 Abdomen finely and irregularly punctured. 



P. silvanoides is described as 24 lines long by | line broad, with the 

 2nd and 3rd antennal joints of equal length. The thoracic sculpture of 

 P. ruf/icoUis will at once lead to its identification. 



Length, 2| lines ; breadth, | li)ie. 



Waimarino. January, 1909. Three were caught under the bark ol 

 fallen trees. 



3089. Parabrontes picturatus Reitter, 



Depressed, with fine short pubescence ; ferruginous, head and thorax 

 often blackish, legs testaceous.
