Serica rubescens, sp. n. 
Rufescens, opaca, ovata, elytris regulariter profunde striatis, sat 
dense minute setosis, capillis longioribus raris erectis, pro-

In his description of Serica maculifera (=variolosa, Motsch.) 
Brenske has mentioned a unicolorous red-brown variety. 
This, although very closely similar to S. variolosa, is un- 
doubtedly a distinct species, to which I have given the name 
above. It is relatively broader than S. vardolosa, much more 
red in colour, often with a yellow scutellum, and the sides 
and middle line of the pronotum yellow as in the other species. 
The eyes are smaller and farther apart, the forehead more 
evenly punctured and without a median caiina, the elytra 
more deeply and regularly sulcate and more finely punctured, 
with more numerous minute setse and shorter erect bristles.

I have seen only three male specimens. 
It is arather large species, of almost the same size and 
shape as Selaserica nitida, Gand., but covered with an opaque 
velvety bloom which leaves only the clypeus, tibia, and tarsi 
shining. The head, pronotum, scutellum, and lower surface 
are of a fairly bright red colour, the elytra very deep red, and 
the pygidium is decorated on each side with a large semi- 
circular black patch placed on the base-line. The lower
