Pliyiophacjous Coleoptera of Japan. 73 
This insect is so exactly similar in form and sculpturing 
to the two preceding- species, that a detailed description is 
not necessary ; its forehead, however, is flatter and less 
deeply grooved. I only know three specimens, all ? ; 
they agree entirely in coloration, and in having the inner 
surface of the intermediate tibiai armed just before its 
middle with a small ill-defined tooth ; this character will 
at once separate it from the two preceding insects. All 
the three species are very closely allied to L. coroman- 
deliana, Fabr. : they may be distinguished from it by the 
following character amongst others : the deepest part of 
the lateral constriction of the thorax in L. coromandcliana 
and its varieties is entirely smooth, whilst in the three 
species before us it is always more or less rugose ; also in 
X. coromandcliana the inner surface of the intermediate 
tibia in the ^ (not the $, as in L. coronata) is armed 
with a small tooth. 
Lcma lionorata. 
Nigra, nitida, peSibus cyaneo-tinctis, capite thoraceque 
rufis, antennis (articuloprimo pra3termisso) nigris ; thorace 
subcylindrico, latitudine distincte longiori, lateribus medio 
constrictis ; disco ante basin leviter, transversim depresso, 
la3vi, medio vitta punctorum minutorum impresso : elytris 
metallico-creruleis, infra basin transversim dcpressis, for- 
titer pvmctato-striatis, interstitiis ad apicem subcostatis ; 
pedibus modice robustis. 
Long. 21—3 lin. 
Ilah. — Nagasaki, found on the Dioscorea. 
Head strongly constricted on either side behind the 
eyes, the latter deeply notched ; forehead impressed with 
a faint longitudinal groove. Thorax distinctly longer 
than broad ; sides deeply constricted at the middle, the 
constriction smooth ; u^^per surface transversely depressed 
in front of the base ; disk very convex, somewhat sub- 
globular, impunctate, with the exception of a double row 
of very fine punctures, which form a longitudinal line down 
the middle. Elytra oblong, ]iarallel ; above convex, 
slightly depressed below the basilar space, the latter 
slightly elevated ; surface deeply punctate-striate, inter- 
spaces towards the apex subcostate. Legs moderately 
robust. 
L. honorata must stand close to L. Lewisil and its 
allies : it may be known by the longer thorax, the smooth 
surface of its lateral constriction, and by the stout legs.
