replaced by an indistinct row of small granules. The 
colour of 7 specimens out of the 8 before me is dark 
broAvnish-coppcry, -with the surface much less shiniuo; than 
in Dellaanii ; the 8th is blueish-black with cyaneous 
margins. There is scarcely any diiferencc in the form or 
scid])ture of the thorax. I can hardly think it to be a 
variety of DeHannii. A distinguisliing character of 
C. Yacotmiiis is furnished by the three interstices exterior 
to the 3rd chain-stria, which arc so strongly crenatcd as 
to be with difficulty traceable.

Very closely allied to C. Yaconinus, but imdoubtcdly 
distinct as a species. It has relatively much longer and 
less oval elytra, Avith the striae and interstices much less 
sharply cut, thus receding from the Avell-marked type of 
sculpture offered by C. prudujus. The stri;e are regularly 
and rather coarsely jDuncturcd, but the interstices are not 
so crenatcd towards the margins and apex as in C. Yaco- 
nimis, consequently the 3 costal exterior to the 3rd chain- 
stria are much more distinct, and the central interstices 
extend to the apex. The 4th cliain-stria is reduced to a 
row of granules. The colour of some dozens of examjilcs 
that I have seen is light brassy-green, chiefly on the inter- 
stices and margin ; very rarely it is violet-black with green 
margins. 
C. 3Iaiyasan2is, u. sp. 
Angustior, reneo-cupreus, nitidus ; thorace angustior, 
ante medium minus dilatato ; elytris conspicue crcnato- 
striatis, stria catenulata 4'" obsoleta, margino exteriori 
lineatim-granulata ; tibiis ct tarsis piceo-rufis. 
Long. ^101— 12 lin. $^. 
Found only at Moon-tcmplc (Maiyasan), Kobe ; alt. 
2,000 feet. 
Of more elongated and narrower form than either of tlie 
preceding, and constantly smaller; colour always bright 
jvneous-coppery, with the tibia; and tarsi reddish. The 
thorax is narrower ; its broadest part is a little before the 
middle, narrowing a little anteriorly and much more so 
posteriorly, yet less cordate than in C. Dellaanii ; sculp- 
tured nearly the same, but punctures rather denser. The 
elytra bear the same proportion to the head and thorax as
