Pselaphidce of Japan. 325 



Bryaxis latifrons, n. s. 



Parum elongatus, niger, antennis, pedibus palpisque 

 testaceis, elytris rufo-obscuris ; capite brevi, vertice bi- 

 foveolato, cumque thorace dense punctatis, hoc trifoveo- 

 lato, foveola inediali parva. Long. If mm. 



Mas, antennis elongatis, articulo secundo magno, glo- 

 boso, tibiis intermediis ante apicem intus spina tenui, 

 elongata, libera armata. Fern, incog. 



Second joint of antennae broader than the 1st, globose ; 

 3rd to 7th slender ; 8th stouter than the preceding ; 9th 

 slightly transverse ; 10th quadrate ; terminal joint 

 rather large. Head destitute of frontal impression. 

 Elytra finely punctulate, with sutural and discoidal 

 striae, — the former does not quite reach the base ; at the 

 base between the two striae there is a small fovea, both 

 sutural and discoidal striae being deep at their origin ; 

 1st dorsal segment at the base with two fine distant 

 lines. 



This species is almost entitled to generic distinction on 

 account of the form of the head, which is less rostrate 

 in front, and destitute of anterior depression, the an- 

 tennae being very widely separated ; the terminal joint 

 of the maxillary palpi is rather small, and the structure 

 of the male antennae and middle legs is very peculiar. 



Two individuals found at Miyanoshita, April, 1880. 



Triomickus, n. g. 



Antennae 11-jointed, widely separated at their in- 

 sertion. Head trifoveolate, eyes with coarse convex 

 facets. Maxillary palpi elongate ; 2nd joint very long, 

 nearly as long as the two following together, slightly nar- 

 rowed or constricted beyond the middle ; third joint with 

 narrow base and oval extremity ; terminal joint elongate 

 and slender, between linear and oval in form, acuminate 

 at the extremity. Trochanters short, though the inter- 

 mediate and posterior femora do not touch the coxae ; 

 hind coxae widely separated, not prominent. Tarsi with 

 a single elongate claw. Ventral segments in the male 

 so abbreviated that the pygidium is scarcely separated 

 from the metasternum. Abdominal margin small. 



This genus seems allied to both Tychus and Bryaxis ; 

 it differs from the former by the structure of the head 

 and palpi, and from Bryaxis by the peculiar palpi. It
