 (hiijus disco excepto) rufo-fulvis ; antennis nigris. 



Long. 5^ lin. 



Hab. New Guinea (Dorey). 



Elongate, convex, parallel, blue-black, nitidous ; head, thorax, 

 limb and apical segments of abdomen, together with the posterior 

 third of the elytra, rufo-fulvous ; the remaining portion of the 

 latter obscure metallic-blue. Head smooth, epistome depressed, 

 separated from the face by an angular groove, just above the apex 

 of which is a large deep fovea, from which a longitudinal groove 

 runs upwards to the vertex ; antennae rather longer than half the 

 body, black. Thorax nearly twice as broad as long, moderately 

 convex, smooth, impunctate, with the exception of four parallel 

 fovea placed two together on either side the disk. Elytra rather 

 broader than the thorax, the sides parallel, apex subacutely 

 rounded ; above convex, shoulders slightly prominent, excavated 

 and concave on the outer side below the shoulder ; each elytron 

 impressed with about ten indistinct rows of punctures, the first 

 very short ; the rows are entirely lost on the posterior third of 

 the surface, which is irregularly punctured ; the spaces between 

 the striae (more especially on the outer disk) are impressed with 

 punctures equal in depth and size to those belonging to the rows 

 themselves, rendering the latter still more difficult to define ; the 

 species, however, doubtless varies greatly in the force and depth 

 of the punctation, one of my specimens being more deeply im- 

 pressed than the other ; in the same specimen the thorax is trans- 

 versely excavated on either side at the base.

Hab. Batchian. 



Elongate, dark shining metallic blue, thorax and legs bright 

 steel-blue. Head smooth and shining, impunctate ; epistome sepa- 

 rated from the face by a deeply impressed angular groove, from the 

 apex of which a shallow curved groove runs obliquely upwards on 

 either side to the upper portion of the eye ; labrum piceous, its 

 outer edge obscure fulvous, its surface sparingly covered with coarse 

 white hairs ; antennae robust, scarcely more than half the length
