394 Mr. G. Lewis on 
In some examples the thorax is infuscate in parts and the 
elytra in others are dusky on the second interstice, part of the 
lateral border, and, rarely, apically. 
Hab. Nikko and Shinkano in July and August. 
Serica higonia, sp. n. 
Oblonga, parum nigra vel nigro-brunnea, azureo-micans, subnitida ; 
capite thoraceque irregulariter punctatis; scutello elongato- 
triangulari; elytris obscure punctato-striatis, interstitiis con- 
vexis; pedibus brunneo-testaceis; antennis basi pallidis, clava 
infuscata. 
L. 6-64 mill. 
This species closely resembles 8. brevicornis in facies and 
surface-sculpture, but the head is less robust, the antenne 
are as large again, the thorax is more convex on the disk, 
distinctly emarginate before the hind angle, arched in front 
of the emargination, and without any anterior angle; the 
scutellum is nearly one third longer than wide; the antenne 
are pale at the base, with the club dark. One example is 
reddish brown, with the head between the eyes, two blotches 
on the thorax, and the elytral, sutural, and outer margins 
dusky with an eneous tinge. 
Hab. Hitoyoshi, Konosé, and Yuyama. Four examples. 
ASERICA, gen. nov. 
This generic name is proposed for a considerable number 
of species hitherto included in Serica. It differs essentially 
from Serica in having smaller eyes, the scutellum wide at the 
base, the hind femora considerably widened and truncate at 
the apices, posterior tibia also dilated, tarsi more robust, and 
the intermediate coxe widely separated. The antenne are 
3-foliate, and the other characters resemble those of Serica.
