" D. hlajHo'idi proxime affinis ; statura minore, pedibiis 
comparatim brevioiibiis, thoracis lined lajvi mediana 
longitudinali nulla vel obsoletii, elytrorimi apicibus multo 
minus productis, discedens." Rye, 1. c. 
Found at Simabara, I. Kusliiu, and Hiogo, in Nipon ; 
both sandy districts. 
The differences between this form and D. hlapto'ides are 
very slight, and I scarcely recognize in Mr. Lewis's speci- 
mens the distinguishing characters draAvn by jNIr. liye from 
the longitudinal line of the thorax and the legs. The 
Japanese themselves, however, distinguish the two forms, 
and when a long series of si)ecimens of each are compared, 
the smaller size, more slender figure and shorter mucro of 
D. Lewisii are sufficiently conspicuous. In size it varies 
from 1 in. 6 lin. to 1 in. 8 lin.

Island of AAva-Sima, off the N. E. Coast of Nipon. 
Distinguished from the D. Fortunei described by 
Schaura, by the coppery colour of the head and thorax, 
the latter of which is more strongly transverse-rugose. 
I have examined both sexes and find the differences con- 
stant. 
jNIr. Adams has recently informed ]\lr. Lewis that it 
Avas on Tabu-Sima that he collected his specimens of this 
insect. The difference of locality is not very material, as 
the two islands are on the same coast, not many miles 
distant from each other.

Yokohama. 
This species has been received in great abundance from 
Yokohama and the S. E. part of Xipon. In a large 
series which I have had an o})])ortunity of inspecting the 
deep blue-black colour of the whole upper surface is con- 
stant. Mr. Lewis never met with it in the Island of 
Kushiu, which is the head-quarters of D. blapto'ides. It 
is at once distinguished by its shorter thorax, dilated in 
the middle, and short, sometimes scarcely prominent clytral 
mucrones.
