A^ertex and front finely but not closely punctured ; face 

 between the eyes impressed with several large, round 

 punctures, which are sometimes absent ; carina short, ob- 

 long ; clypeus transversely trigonate ; antennre more than 

 half the length of the body ; four lower joints obscure 

 fulvous, 5th and 6th, together with the upper surface ot 

 the basal joint, piceous, the five outer joints black. Thorax 

 nearly three times as broad as long ; sides rounded and 

 converging from base to apex, the anterior angle produced 

 in front, thickened, its apex obtuse ; upper surface subre- 

 motely punctulate, the interspaces fanitly rugulose. Llytra 

 finely punctured, finely and irregularly rugose-strigose. 

 Hinder tibiffi recurved below the middle, channelled above, 

 edges of the groove serrate. Third joint of all the tarsi, 

 together with" the claws, obscure piceous. , . ... 



The irregular surface of the thorax and elytra (visible 

 only under a good lens) will separate this insect from D. 

 intermedia.

 tennis (basi fulva excepta) nigris ; thorace subremote punc- 

 tato, lateribus fere rectis, angulis anticis incrassatis, oblique 

 truncatis ; ely tris siibseriatim punctatis.
