Zoological Department of the British Museum. 
[Read 4th March, 1867.] 
Genus Damastnr, Kollar. 
Damaster auricollis, spec. nov. (Tab. XXVIT. fig. 1.) 
D. elongatus, angustatus, sat nitidus, violaceus; capite 
thoraceque aureo-viridibus ; thoracis disco subtiliter 
transversim striguloso; elytris granulosis, apice 
non producto. 
Long. 144 lines. 
Hab. Japan (Hakodadi). 
In form approaching D. Fortunei, but the head and 
thorax are relatively shorter. 
Head narrower than the thorax, cylindrical, golden- 
= en, with a deep furrow on each side, reaching from 
the eyes nearly to the anterior margin (deeper than im 
D. Fortunei, and terminating more abruptly) ; the part of 
the head i ‘in front of the antenne is black and glossy, the 
hinder part somewhat thickly punctured with irregularly 
shaped punctures. Thorax with adelicate central furrow, 
golden-green, narrow in front, without anterior angles, 
gradually broadening to the middle, then gradually 
contracted ; at the posterior angles somewhat abruptly 
dilated, the angles somewhat acute; lateral margins 
gently reflexed; sides rugulose, hinder margin more 
strongly rugose-punctate, the disk covered with fine 
transverse scratches. Elytra elongate-ovate, viola- 
ceous, not, or but scarcely, produced at the apex, 
somewhat strongly rugosely punctured, the raised parts 
forming some indistinct longitudinal lines. Underside 
violaceous, glossy, except “the sides of the thorax, 
which are somewhat dull golden-green, and the apex 
of the abdomen, which is rugulose-punctate. Tibie, 
tarsi, palpi, and antenne, black; the last having the four 
basal joints glossy, the others covered with fuscous hair. 
There is considerable difference in form between the 
males and females of these insects, the males being much 
narrower. The specimens of D. Fortunei before me differ 
also in the sculpturing of the thorax, the punctuation
