Rather shorter than Pselaphus Heisei, more depressed, 

 and with the hind body narroAver. Antenna not quite so 

 long as head and thorax, rather stout, first joint stout, 

 moderately long ; 2nd joint also stout ; 3rd joint about 

 as long as broad ; joints 4 — 8 scarcely differing from one 

 another, small, each not so broad as long ; 9th joint short, 

 a little broader than 8th ; 10th distinctly broader than the 

 9th, very transverse ; 1 1th joint pointed, stout, broader than 

 the 10th joint, and about as long as the three preceding 

 joints together. JNIaxillary palpi about half the length of 

 the antennae. Head with the frontal processes flat, elongate, 

 and separated by a distinct channel, which terminates behind 

 in a rather deep impression, formed by two confluent fovete, 

 which is placed between the eyes. Thorax only about half 

 as broad as the elytra, rather longer than broad, the sides 

 very finely margined, the gi'eatest Avidth in front of the 

 middle, from Avhence it is much narrowed both in front 

 and behind ; it has on each side behind the middle, close to 

 the side margin, a very minute dot or fovea, and there are 

 some faint traces of these being connected by a curved 

 impression ; the u]iper surface of the thorax is peculiarly 

 dull, and on examination by a high power of the micro- 

 scope, it is seen that this duluess arises from a very fine 

 and dense granular scidpture ; the sides of the thorax 

 bear some fine curved hairs, and there are also a few such 

 hairs on its upper surface. Elytra longer than the thorax, 

 a little narrowed at the shoulders, each with a sutural, and 

 a fine curved discoidal stria, and with some fine hairs in- 

 distinctly arranged in rows, and at the extremity Avitli some 

 very dense glandular pubescence. Hind body with a sharp 

 raised margin, and bearing scattered fine hairs ; its basal 

 segment shining, elongate, and furnished at the base with 

 dense pubescence, the other segments very short. Legs 

 rather short and stout.
