Species o/Pselapliidge/roJu New Zealand. G95 



January 1911, and a male found amongst decaying leaves 

 collected by Mr. W. J. Guinness near Mount Ngauruhoe. 



This, the finest species of the genus, is named in honour of 

 M. Achilles RafFray, who has spent the best of his lifetime 

 in studying the Pselaphidse. 



3383. Zealandiiis illustris, sp. n. 



Nitid, slightly convex, castaneo-rufous ; an(enna3, palpi, 

 and legs fulvescent ; pubescence short, pale yellowish, very 

 scanty on the head and thorax, and with a few upright elon- 

 gate hairs on the hind body. 



Head rather elongate, not as broad as the thorax, slightly 

 narrowed beliind the small convex eyes; relatively'' coarsely 

 and irregularly but not closely punctured, its surface never- 

 theless is quite shining ; interocular fovese small, not sharply 

 defined, and only very indistinctly prolonged forwards, the 

 interantennal portion depressed. Thorax of about equal 

 length and breadth, widest before the middle, rounded there, 

 much narrowed anteriorly ; its punctation like that of the 

 head, but more distant and shallow on the disc and nearly 

 obsolete in front ; lateral fovese subrotundate, median sulcus 

 rather broad, almost touching the front and dividing the 

 transverse basal impression. Elytra suboblong, gradually 

 narrowed towards the shoulders, without visible punctation ; 

 Rutural and dorsal strise broad, deep at the base, the dorsal 

 becoming shallow near the apices, the lateral indistinct, 

 with subcarinate interstices; the extremity of each elytron, 

 near the side, is slightly raised, but not tuberculate. Hind 

 hody as broad as the elytra, apparently impunctate, its basal 

 three segments almost equal, the first witli an indefinite 

 median transverse impression at the base. 



Antennce moderately elongate, finely pubescent; basal 

 joint rufescent, stout, cylindric, the next oblong-oval, more 

 slender, and rather shorter; third and fourth obconical, 

 rather small, fifth oblong-oval, seventh rather longer than 

 the subquadrate sixth or eighth, the ninth evidently larger 

 than the eighth but not as broad as the transverse tenth ; the 

 terminal large, about as long as the preceding two together, 

 conical and distinctly acuminate. 



Legs moderately elongate, femora stout; the intermediate 

 tibite thicker than the others, abruptly narrowed at the extre- 

 mity, so that near that point on the inside there is an angu- 

 lation or obtuse calcar; the anterior are similarly but much 

 less distinctly angulate near the apex.
