Geodephagous Cohoptera of Japan. 245 
length of his msect and the locaHty East Indies, I feel no 
doubt that the species is the same as the Japanese one, his 
description being (unusually for him) exact and fidl. But he 
had no reason whatever for referring it to the genus Pero- 
nomerus, the essential character of Avhicli is the large size 
and unilobular form of the first tarsal joint of the anterior 
feet in the $ . The thorax in D. quadrinotatus is suboval, 
much more narrowed anteriorly than behind, -with rather 
produced hind angles, and yellow lateral border, Avhich is 
broadish near the base, and narrows to a point before 
reaching the anterior angle.

Long. 31— 4 lin. ^2. 
Nagasaki; abundant in May; under stones in Mitsu- 
yama, in May. 
Of precisely similar form to the Chinese P. fumatus. 
Thorax very similar, rhomboidal, with prominent lateral 
angles and sinuate margin between the angles and the 
base. Differs in the brownish-black colour of the integu- 
ment (instead of brassy-black), and griseous instead of 
fulvous pubescence. 
It might more properly be treated as a local variety of 
P. fumatus. A series of more than twenty of each taken 
by Mr. LcAvis, when placed side by side, exhibit the dis- 
tinctive characters very clearly. P. ceratus of Dacca, in 
Bengal, differs only in the narrower and more obtuse 
angled thorax.

Hakodadi. Not met with by Mr. Lewis. 
The description by Morawitz agrees closely with that ot 
Chaudoir, and it is not clear why the former came to the 
conclusion that his species was distinct. It is a large 
handsome species, nearly half an inch in length, with red 
legs.
