102 Mr. C. O. Waterhouse on the 
Serica polita, Gebler. 
S. polita, Gebler, Nouv. Mém. Mose. ii. p. 52. 
This is an extremely variable insect. The ordinary co- 
louration brownish-testaceous, with a slight eeneous reflec- 
tion, but sometimes the head and thorax are bluish-seneous, 
and rarely the whole insect is greyish-zeneous. It is this 
last variety which I have determined to be VS. polita of 
Gebler. In Mr. Lewis’ collection there is a specimen, in 
bad condition, of an insect which agrees very well with 
Motschulsky’s description of S. grisea, and it appears to 
me to be very probable that this is only a variety of S. 
polita. I see only colour-differences, but do not like to 
unite the two upon such slight evidence. 
Hab.—Japan; Dauria. 
Serica japonica, Motsch. 
S. japonica, Motsch. Etud. Ent. 1860, p. 15. 
“‘Ovata, convexa, sparsim punctata, velutina, rufo-cas- 
tanea, oculis nigris, nitidis; clypeo truncato, reflexo, 
confertim fortiter punctato; thorace transverso, antice 
arcuatim angustato, sparsim punctato, angulis anticis pro- 
minulis, posticis rectis; elytris thorace paulo latioribus, 
ovatis, striatis, interstitiis subconvexis, sparsim punctatis ; 
corpore subtus punctato, opaco. 
Long. 3 lin.; lat. elytr. 21 lin.” 
In this (as was evidently Motschulsky’s frequent cus- 
tom) the author took the measurements from an inch 
divided into eighths instead of twelfths. The size should 
be 44 lin., 34 lin. 
Hab.—Japan, in all the islands; Hong Kong.
