 thorace subncneo, dense et parum profunde punctato, in medio 

 valde dentato ; elytris punctato-striatis ; antennis articidis V-G"^

This species is rather larger than L. tomaroides, and like 

 it has one very prominent tooth on the middle of the lateral 

 edge ; but the chief difference is in the antennas, the four 

 apical joints are nearly black, and the 3-jointed club much 

 more robust. 



Hah. Oyayama, June 1st, 1881. One specimen. 



Lissodema tomaroides j sp. n. 



Breve, brunneo-nigrum, nitidum ; capite sparse punctato, utriuque 

 carinato ; thorace lateribus in medio valde dentato ; elytris in 

 medio latioribus ; antennis pedibusque brunneis. 



L. lf-2 mUl. 



Rather short, brownish black, shining ; the head carinate 

 on either side over the eyes and as far as the antennae, not 

 closely punctured, especially between the eyes ; the thorax 

 closely and more coarsely punctured than the head, the 

 second lateral denticulation from the base is at the middle of 

 the thoracic margin and is very prominent, two anterior 

 teeth obsolete ; the elytra widest in the middle, rather 

 browner than the thorax, punctate-striate ; the antennae are 

 slender and relatively shorter tlian others of this series, and 

 are with the legs pale brown. 



Resembles a species of Corticaria or Tomarus. 



Hah. Miyanoshita. Found rather commonly. 



Lissodema minutum, sp. n. 



Breve, brunneo-nigrum, nitidum ; capite utrinque carinato, sparse 

 punctulato ; thorace transverso, dense punctato ; elytris late 

 ovatis, punctato-striatis ; antennis basi pedibusque pallide brun- 

 neis.

This minute species is remarkable in having the thorax 

 distinctly transverse and the elytra broadly oval. The elytra 

 are much broader than the thorax. 



Hah. Oyayama. One example, June 1st, 1881.
