Pselaphidce and Scydmanida of Japnn. 117 



Batrisus and Evplectus. The antenna are slender, slightly 

 longer than head and thorax, the basal joint very short, 

 not concealed, stout; 2nd joint short, about as long as the 

 first; joints 3 — 8 slender, the 8th smaller than the 7th; 

 9 and 10 larger than the preceding ones but still slender; 

 1 1th joint stouter than the others, moderately large, pointed. 

 Head rather short and broad, with the eyes about as broad 

 as the thorax; it is dull, being closely and coarsely punc- 

 tured. The antenna! tubercles are small, and there is a 

 transverse line connecting them. Thorax small, much 

 narrower than the elytra, scarcely so long as broad, rounded 

 at the sides and much narrowed laehind ; it is, like the head, 

 coarsely punctured, except the projecting sides, which are 

 smooth and shining; it is channelled along the middle, 

 obscurely impressed in front of the base, with the smooth 

 side parts separated from the disc by a fine line. Elytra 

 rather longer than the thorax, a little inflated, the humeral 

 angles rounded, almost impunctate, each with a fine sutural 

 stria, and a strongly marked central stria, this, however, 

 not reaching quite to the extremity. The hind body is 

 quite unmargined, the first segment elongate, about two- 

 thirds as long as the elytra, the two following segments 

 very short: the first segment beneath is also elongate. 

 Tlie legs are rather long and slender, the tarsi (especially 

 the hind ones) particularly slender. 



Nagasaki; two specimens. 



In one of these the antennas is considerably stouter than 

 the other, this is no doubt the male. The species will 

 probably ultimately be separated as a distinct genus from 

 Jjatrisus. 



MoEANA, nov. gen. 

 Of a short, broad, subdepressedform. Antenna distant 

 at point of insertion, 11 -jointed, the apical joint very large 

 in proportion to the others. INIaxillary palpi not observed 

 but certainly small, and probably without important 

 characters. Hind body margined on the dorsal surface 

 with only four visil)le segments, the 1st of these elongate, 

 the 2nd rather short, the 3rd still shorter, the last forming 

 the pygidium, moderately long ; on the under-surface with 

 five visible segments, the first very elongate, the three 

 following ones extremely short and compressed, the fifth 

 short. Legs with the tibiae laterally compressed, the tarsi 

 rather short and stout, 3rd joint shorter than 2nd, with 

 two equal unguiculi ; the posterior coxje slender and not
