Hab. — Nagasaki, on the ivy. 
Lower portion of face more or less deeply excavated, 
forehead finely and remotely punctured. Thorax with 
the sides obliquely narrowed from base to apex, rather 
less oblique at the base, hinder angles obtuse ; basal margin 
oblique on either side, the basal lobe very slightly produced, 
subangulate, disk distinctly but finely punctured, the punc- 
tures subremote. Elytra more strongly punctured than in 
L. cupreatum, the punctures subrotundate. 
The present insect may be at once distinguished from 
the preceding by its different coloration and by its longer 
and narrower form ; both species are separated from our 
L. concolor (to Avhich they are closely allied) by the absence 
of the deeper punctures which form regular longitudinal 
striffi on the elytra of that insect.
