Ilakocladi. Not in ]Mr. LgavIs's collection. The facies 
and shape of this elegant species are those of Damaster, 
but the dilated tarsi of the <? connect it with Carahus. 
especially with the Coptolahriis o-mup. The degree of 
dilatation, however, is \ovy slight, Aery different to what 
exists in Copiolabrus.

Among the luimerous described species fi'om Japan and 
North China belonging to the C. prodiyus group, the 
]n*esent is distinguished by its large size (15 to 18 lines), 
hlueish-hlack coloiu*, impinictate strias of the elytra, and 
the presence of a fourth distinct "chain stria" towards the 
lateral margin of each elytron, beyond which there is a 
broad rugose space and indications of other strife. All 
the numerous examples I have seen of the two sexes agree 
in these features. The general form of the insect is broad, 
and only moderately convex ; the thorax approaches the 
cordate shape, that is, its Avidest part is before the middle, 
whence it narrows moderately, in a slightly incurved line 
to the hind angles. All the specimens agree in colour; 
deep black, with a blueish tinge most perceptible on the 
sides of the thorax and the elytra. 
Heaths and Avoods, generally distributed. 
Var. jiimctato-sfriatus. In tAvo of ]\Ir. Le^vis's speci- 
mens the interstices of the elytra are distinctly crenated, 
the indentations increasing in strength toAvards the apex. 
In the absence of other differences I do not venture to 
separate them specifically. 
C. Yaconiniis, n. sp. 
C. DeHaanii paululum minor et angustior, supra 
fnsco-cupreus, A'ix nitidus ; thorace subcordato, supra 
rugoso-punctato, elytris conspicue crenato-striatis, stria 
catenulata 4*^ obsoleta ; margine confuse gramilato-rugoso. 
Long. 13—14 lin. $ $ . 
Rather narroAver than DeHaanii in both sexes, and 
distinguishable from the crenate-striate form of that species 
by the absence of the fourth (lateral) chain-stria, this being
