STAPHYLINIDAE. 15 



Pubescence greyish, the outstanding hairs at the sides and apex of the 

 abdomen are dark. 



The coloration, longish elytra, and thoracic punctation are distinctive 

 characters.

Waimarino. Another of my captures in January, 1909 ; only one, 

 unfortunately. 



3036. Quedius longiceps sp. no v. 



Elongate, much narrowed anteriorly, moderately shining, rufo-fuscous, 

 abdomen somewhat violaceous ; the palpi, legs, and antennae testaceous, 

 basal joint of these last paler ; pubescence obscure yellowish. 



Head long and narrow, the length double the breadth, tripunctate near 

 each eye. Thorax of equal length and breadth, much narrowed towards 

 the front, with 4 apical punctures, 2 antemedian, and 4 basal. Scutellum 

 rather large, triangular, finely punctate. Elytra subquadrate, apices oblique 

 towards the suture, distinctly but not coarsely punctured. Abdomen rela- 

 tively very elongate, its sculpture like that of the elytra, but with the apical 

 portion of the 3rd, 4th, and 5th segments nearly smooth. 



Eyes elongate-oval, hardly half the length of the head. Antennae finely 

 pubescent from the 4th joint onwards, 2nd joint longer than 3rd, the 

 following 7 subquadrate, 11th oviform, rather longer than the penultimate. 

 Anterior tarsi only moderately expaaided. Clypeus not pallid. 



The peculiarly elongated head and the antennal structure are good 

 differentiating characters. 



Length, 2| lines ; breadth, J line. 



Raurimu. January, 1909. One female. 



Obs. — Quedius ruficornis having been used before, I have renamed my 

 No. 205 Q. manaiaensis. It somewhat resembles Q. tinctellus. 



Group Pederidae. 



3037. Dimerus stilbus sp. nov. 



Subcyhndric, medially 'narrowed ; head, thorax, and elytra shining, 

 sanguineous ; hind-body subopaque, castaneous, covered with slender 

 yellowish-grey hairs ; tarsi, tibiae, and antennae fulvescent, femora darker ; 

 mandibles shining, red. 



Head rather broader but shorter than thorax, the elongate frontal im- 

 pressions separated from the eyes by cariniform elevations, the punctation 

 rather irregular and coarse but nearly absent along the middle, forehead 

 subtruncate between the antennae. Clypeus very short and pallid. Labrum 

 very broad, finely serrate in front, and with a pair of spines at the middle. 

 Eyes with coarse facets, quite lateral, half the length of the head, very 

 narrow. Mandibles falciform, as long as the head, very slender and acute 

 towards the extremity, edentate at the base, but with a very long median 

 tooth. Antennae implanted just above the base of the mandibles, 7th joint 

 very small and bead-like, the penultimate abruptly enlarged and subquad- 

 rate, the terminal longer. Thorax longer than broad, widest near the front, 

 gradually narrowed towards the base, with a short basal neck ; along each 

 side of the middle, but not reaching the apex, there is a deep groove ; there 

 is a similar one near each side ; between these, in front of the middle, there 

 are 3 slight punctiform impressions ; near the base 4 indefinite punctures 

 can be seen ; the pubescence, like that of the head, is very inconspicuous 

 and scanty. Elytra about half the length of the thorax, much curvedly
