abruptly); the part of tlie head in front of the antennae is black 

 and glossy, the hinder part some what thickly punctured witli 

 irregularly shaped punctures. Thorax with a delicate central 

 furrow, golden-green, narrow in front, without anterior angles, gradu- 

 ally broadening to the middle, then gradually contracted: at the 

 posterior angles some what abruptly dilated, the angles some what 

 acute; lateral raargins gently reflexed; sides rugulose, hinder margin 

 more strongly rugose-punctate, the disk covered with fine transverse 

 Scratches. Elytra elongate-ovate, violaceous, not, or but scarcely, 

 produced at the apex, some what strongly rugosely punctured, the 

 raised parts forming some indistinct longitudinal lines. Under- 

 side violaceous, glossy, except the sides of the thorax, which are 

 some what dull golden-green, and the apex of the abdomen, which 

 is rugulose-punctate. Tibiae, tarsi, palpi, and antennae, black; 

 the last having the four basal joints glossy, the others covered with 

 fuscous hair. 



There is considerable difiference 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 being rugulose in some, and every 

 puncture being distinct in others, but I have little doubt that they 

 are all the same species; one variety has the thorax blue. 



The comparatively short head and thorax, and the rugoselj' 

 punctured elytra will easily separate B. auricollis from D. fortunei, 

 whilst the absence of any production to the apex of the elytra will 

 separate it from both D. fortunei and D. blaptoides/^ 



Die der Beschreibung beigegebene Abbildung ist in den Farben 

 zu lebhaft, namentlich das Violett der Flügeldecken, die Struktur 

 der Flügeldecken ist zu skizzenhaft wiedergegeben, doch läßt sich 

 im ganzen die Art erkennen.
