and less closely set than those of the* head; the scutellum 
punctate, somewhat elongate, obtuse behind ; the elytra with 
eight or nine shallow furrows occupied with confluent punc- 
tures, interspaces feebly convex and smooth; the pygidium 
irregularly, not densely punctured; the antenne and legs 
concolorous. 
Hab. Miyanoshita, Hakone, Subashiri, Ontake, Nikko, and 
Yokohama. Sixteen examples.

If I have determined this species correctly, it is very 
variable in colour. I have only one specimen, which agrees 
in having the dark lines on the elytra. The elytra are 
usually pale with the sutural interstice infuscate, or sometimes 
wholly pale ; the head sometimes is, with the thorax, wholly 
geneous, but generally theeclypeus is testaceous.

In this genus the intermediate coxee of typical species are 
approximate and the antenne usually 3-foliate; but I have 
included three species in it in which the antenna of the male 
is 4-foliate. The genus Serica, as it formerly stood, has lately 
been divided into three or four genera.

This species has been standing in the Catalogue as 
S. brunnea, Linn.; but, although the colour agrees in both 
species, there are structural differences. In S. similis the 
eyes are smaller and less convex, the anterior thoracic angles 
are acute and less depressed, the elytra are shorter and less 
parallel, the mesosternum is wider between the intermediate 
cox, and the tarsi more slender. ‘This comparison has been 
made with the males of both species. ‘The head is sometimes 
wholly pale, sometimes black between the eyes, and some 
specimens are piceous beneath; the elytral sculpture also 
differs slightly in the two species. 
Hab. Nagasaki, Hitoyoshi, Nikko, and on the Wada-togé. 
Rather common.
