56 Mr. David Sharp on the 
Allied closely to our European species marinus and 
Suffriani. It is rather broader and more convex than 
marinus, and it differs from it by the punctures of the 
8tria3, which become finer towards the extremity, and also 
by the absence in both sexes of the fine sculpture of the 
upper surface which is so distinct in the females of mari- 
nus. It is more nearly allied to Suffriani, and it much 
resembles that species in the punctuation of the elytra, 
but it is so much larger and broader that the two cannot 
be confounded. The internal strife of the elytra are quite 
distinct, but they are a little finer than the lateral ones. 
The claAvs of the tarsi are red and unspotted ; the inflexed 
margin of the prothorax is reddish ; the epipleurae of the 
elytra are seneous, a little rufescent in the middle in their 
basal half; the femora of the four hinder legs are pitchy in 
the middle. 
Abundant at Hiogo and Nagasaki. 
Obs. — Besides the specimens described above, I have 
seen two other specimens (^ and 9) of a Gi/rinus from 
Japan (one in Mr. Lewis's collection from Nagasaki, and 
one from another source in my own). They may prove 
to be a distinct species from the above, being considerably 
smaller, having the inflexed margin of elytra and thorax 
red, and the femora entirely red. I should like to see 
more specimens to confirm their claim to be considered a 
distinct species. It is possible they may be the species 
intended by Motschoulsky under the name of G. curtuSf 
but I have not been able to consult his description.

Allied to D. spinosus, Aube, but larger and broader, 
and with the internal tooth on each elytron not broader 
than the external one. The upper surface is metallic, 
with a yellow margin extending from the fi'ont of the 
thorax to the first tooth of the elytra ; internal to this is a 
greenish stripe, and inwards from this two dark purphsh 
coppery stripes, these stripes being separated fi-oni one 
another by obscure strife ; at the base, near the suture, 
there are also traces of two of these dark copper stripes :
