 pressed parts confluently punctured and very faintly gilded ; with three 
subinterrupted longitudinal ridges connected by transverse levigated ele- 
vations ; the two external ridges become confluent and proceed as a single 
ridge to the apex; lateral margin towards the apex minutely serrulate : 
back of the abdomen of a fine silky green: underside of the body thinly 
planted with hoary hairs; prosternum constricted in the middle and ter- 
minating towards the anus in a dilated trilobed point: shoulders much 
_incrassated, armed below with a stout tooth ; cubits clubbed at the apex ; 
four anterior tibiae bent or bowed: hypopygium bidentate. [Belongs 
to the genus CÆrysobothris Esch. ‘Taken in Canada, and, according to 
Dr. Le Conte, in the following localities : ‘Lake Superior, Lake Winni- 
peg, Oregon and Washington Territories.” He states that “the colour 
beneath is somewhat variable, and that he has a © with the body entirely 
green, and a ® in which it is coppery, with purple spots at the sides of 
the abdomen. ‘The sides of the thorax are sometimes straight, sometimes 
rounded, but it is never obviously wider in front.” ]

lines. A single specimen taken in the Expedition. 
[158.| Body minutely and thickly punctured : above black- bronzed 
obscure ; underneath cupreous with the gloss obscured ; except near the 
anus, cloathed with numerous rather long decumbent hoary hairs. Head 
somewhat cupreous, hoary from decumbent hairs; nose green, bilobed 
with divaricated lobes, including a somewhat obtusangular sinus ; antennae 
green ; vertex channelled: prothorax embossed in the disk, impressed 
and wrinkled at the sides; depressed parts punctured and reflecting a 
faint lustre of copper : scutellum an isosceles triangle, depressed and green 
at the base, elevated part black: elytra embossed, with a ridge extending 
from the apex where it is broader, by the side of the suture towards the 
base where it is abbreviated: the depressed spaces have a faint lustre of 
copper and bronze, and are thickly punctured ; apex rounded and obso- 
letely serrulated : shoulders incrassated with a short robust tooth : all the 
tibiae are bent or bowed ; cubit not dilated at the extremity: hypopygium 
with a deep sinus. 
This nearly resembles 2. O. frinervia, but is sufficiently distinguished 
by having only a single ridge on the elytra, and the posterior tibiae as 
well as the other pairs, bowed: the prothorax also is not channelled and 
its sides are rounded. [Belongs to Chrysobothris. Is not included in Le 
Conte’s List. |
