Black, shining; the head a little prolonged before the eyes, 

 with two lateral impressions near the bases of the antennae, 

 mouth-organs palish ; the thorax 4-dentate, narrowed at the 

 base behind the posterior denticulation, densely punctured, 

 with one very distinct fovea on each side near the base ; the 

 elytra punctate- striate at the base, the strise gradually 

 becoming punctiform after the middle, behind the humeral 

 angle and extending across the wing-case nearly to the 

 sutural stria is a pale yellowish spot, more or less defined 

 and in one specimen almost absent; the antennai, joints 1—8 

 reddish brown, 9-10 black, terminal reddish at the apex 

 only ; the legs, thighs infuscate, tibiae and tarsi pale brown. 



This is the most elongate species of this series. 



Hah. Junsai. Four or five examples. 



Lissodema pictipenne^ sp. n. 



Breve, nigrum, nitidum ; capita parum sparse, thorace dense 

 punctatis ; elytris distincte 4-maculati8, maculis flavis ; tibiis 

 tarsisque pallide brunneis. 



L. 2f mill. 



Black, shining, body somewhat short ; the head punctured, 

 punctures clear but not set closely ; the thorax, 4-denticulate 

 laterally, little narrowed at the base, with two shallow foveas ; 

 the elytra widest at the middle, punctate-striate, punctures 

 not evanescent at or before the apices, with a transverse, 

 somewhat broad, flavous spot before the base, which reaches 

 from the sutural stria outwards nearly to the edge, and there is 

 a second somewhat oval spot on each wing-case before the 

 apex; the legs, thighs darkish, tibia? and tarsi pale brown; 

 the antennjfi, joints 1-8 obscurely brown, 9-11 somewhat 

 large, infuscate, with the apex of the last reddish. 



The somewhat enlarged apical joints of the antennse 

 distinguish this species from others of the series, except 

 L. validicorne. 



Hah. Chiuzenji. One example, August 23rd, 1881. 



Lissodema loivipenne, Mars. 



This species was found originally at Nagasaki, but I met 

 with it afterwards in various places as far north as the plain 

 of Fujisan.
