differences are :—the thorax is more transverse and pale and 
pellucid, except on the disk; the disk is black, and leaves 
only a very narrow pale margin behind the neck; the an- 
tenne are less strongly pectinate (being in this respect inter- 
mediate between /. ramicornis and granicollis), and the joints 
1 to 5 are testaceous, but the pectinations on joints 3 to 5 are 
black. 
flab, Fukushima, 26th July, 1881. Two examples, both 
males. 
Prionocyphon sexmaculatus, sp. n. 
Ovalis, convexus, testaceus, pubescens ; thorace transverso ; elytris 
6-maculatis, maculis piceis ; antennis pedibusque concoloribus. 
L. 43 mill. 
Oval, convex above, palish testaceous, rather. densely 
pubescent; the head scarcely punctured, very shiny, trans- 
verse ; the thorax also very shiny, sinuous before and behind, 
very transverse and very short, with a faint leather-like sculp- 
ture; the scutellum large, triangular, and feebly punctulate ; 
the elytra rounded off at the shoulder, with a large oval 
blackish spot on each side on the scutellar region, a second 
about half the size of the first below the shoulder and near 
the outer margin, and a third large lobe-shaped spot behind 
the middle of the dorsum, which leaves a sutural and epi- 
pleural margin of about the same width; the antenne, basal 
joint rather large, second and third small, especially the 
third; the legs with the antenne wholly pale. 
Hab. Nikko. One example. 
Scirtes ovatulus, sp. n. 
Ovalis, fuscus, nitidus, pubescens ; antennis basi pedibusque obscure 
brunneis. 
L. 23 mill. 
This species is very similar to S. sobrinus, but it is less 
circular in outline, having longer elytra, and the antenne are 
more robust, the joints feebly increasing in size towards the 
apices ; the legs also are wholly but obscurely brown. 
Hab. Hakodate. 
Scirtes sobrinus, sp. n. 
Breyiter ovalis, piceus, pubescens; antennis pedibusque pallide 
brunneis. 
L, 23-23 mill. 
Broadly oval, pitchy brown, shining, pubescent; the head
