and species of PselaphidcB and Sc7jdm<Bnkl(E. 491 



Tjp-aplms brevis, n. sp. Antice castaneus, opacus, 

 postice rufo-testaceus, nitidus; protliorace latitudine hand 

 longiore. Long. corp. 1^ mm. 



. iF¥? «lf cies, of which I have seen only a single female 

 individual, IS very closely allied tc the T. planus, but is 

 more dilated behind, and has the thorax, and the front 

 part of the head, very evidently shorter; the antennas are 

 also a trifle shorter, and I have no doubt these characters 

 indicate a distinct species. 



West Australia ; collected by Du Boulaj. 



Tyraphiis major, n. sp. Antice castaneus, opacus, 

 postice rufo-testaceus, nitidus; oculis magnis, fortiter 

 granulatis; prothorace latitudine longiore. Long. corp. 

 2 mm. 



Antennre rather stout, quite as long as head and thorax, 

 basal joint stout and rather long; 2nd joint not half so long 

 as the first ; joints 3 — 8 rather stout, differing little from 

 one another; 9 and 10 short, stouter than the preceding 

 joints ; 1 Itli quite as long as two ]n-eceding joints together, 

 broader than the 1 0th, pointed at the extremity. Maxillary 

 palpi not half so long as the antennae. Head with the 

 frontal processes separated by a fine channel, which ends 

 behind in a depression placed behind the eyes, these large 

 and very coarsely facetted. Thorax narrow and rather 

 elongate. The glandular pubescence at the extremity of 

 elytra dense and elongate. The apical four dorsal seg- 

 ments of hind body quite distinct, and, taken together, as 

 long as the first segment. 



Champion Bay, W. Australia, collected by Du Boulay ; 

 the only specimen I have seen I suspect to be a male, 

 though the metasternum and hind body are not im- 

 pressed ; the species, though closely allied to T. planus and 

 brevis, is larger, and has more developed antenna?, much 

 larger eyes, and the apical segments of hind body less 

 abbre\dated. 



Pselaphus mundus, n. sp. Rufescens, minus dongatus, 

 setis brevissimis parce vestitus; vertice brevi, indistmcte 

 canaliculato ; prothorace minus elongate, impressioue basali 

 curvata profunda. Long. corp. If mm. 



This species has the head and thorax less elongate than 

 is usual in the genus Pselaphus, and in this respect, as
