very moderately raised and the raised edge ceases before the 
eyes; the pygidium is not transverse like the other species 
of this series, it is nearly as long as broad. 
Hab. Nagasaki. Also at Chefoo in China. 
Lachnosterna niponensis, sp. n. 
Brunnea, parum parallela, convexa, subnitida; capite thoraceque 
punctatis ; scutello levi haud punctato; elytris punctatis, inter- 
stitiis parum convexis. 
L. 19-21 mill. 
Brown, subparallel, convex above, rather shining; the 
head roughly and closely punctate, punctures on the clypeus 
dense, especially in the middle of the base, anterior rim of the 
clypeus distinctly raised and feebly emarginate in the middle, 
neck smooth, but the smooth space is of irregular outline ; 
the thorax irregularly punctate, punctures rather less closely 
set than those of the head, lateral edges widely crenulate, 
transverse and slightly bulging in the middle of the lateral 
edges, angles before and behind obtuse ; the scutellum widest 
at the base, with anterior portion clothed with golden-tawny 
hair ; the elytra, interstices uneven and punctate, punctures 
not so dense as those of the thorax, sutural margin rather 
broadly elevated from the base to the apex, the next raised 
costa is similarly broad but shortened before and behind, both 
smooth and almost impunctate, outside there are other coste 
ill-defined and vague; the pygidium uneven and sometimes 
closely but shallowly punctured, rather broad and somewhat 
arched at the base, slightly convex; the legs, apices of thighs, 
and the club of the antenna dusky. 
This species is the largest of the genus known from Japan; 
in colour it corresponds with Serica brunnea, L. ‘The scu- 
tellum is quite smooth in some examples, irregularly punctate 
in others, and in one specimen closely punctate; sometimes it 
is rounded off behind, but usually it is obtusely acuminate.

The author of this genus says of it: “ Antennes de 11 
articles, dont le 4*™° trés court ; massue longe, de 7 articles.” 
The basal joint of the antenna is long and very similar to 
that of Rhizotrogus; the second is apically bulbiform and 
constricted at the base; the third elongate, but not so long as 
the first, and is minutely angulate on the inner edge; the 
fourth is short, with a small acute appendage; the fifth is
