angles, basal sulcus deep and sinuate, the disc extremely minutely 

 but remotely punctured. Scutellum black. Elytra parallel,

Hub. Assam : Khtisi Hills. Type in Coll. Jacoby. 



Of uniform metallic blue colour and distinguished by the

Metallic dark blue ; antennae and legs black. 



Short and rather broad. Head with a few fine punctures, vertex 

 only slightly convex, with short ceutral groove ; antennae slender, 

 third and following joints elongate, the third joint half the 

 length of the fourth. Thorax somewhat broader than long, deeply 

 constricted near base, anterior angles nontuberculate ; surface with 

 deep transverse sulcus near base, impunctate. Scutellum rather 

 broad. Elytra with deep transverse oblique depression across 

 suture below base, the latter broad, with prominent shoulders ; 

 surface strongly and closely punctate-striate, punctures verv 

 closely placed, interstices slightly transversely wrinkled. Under- 

 side clothed with short silvery pubescence. 



Length 4-5 mm.

The Burmese specimens formerly named by me ivallacei do not 

 really seem to differ from Fabricius' species under which wattacei 

 must stand as a synonym.

Weise, Deiit. ent. Zeit. 1903, p. 22. 



Metallic dark blue ; abdomen flavous. 



Head not constricted posteriorly, the neck rather swollen, intra- 

 ocular space not tuberculiform, nearly plane, with a short central 

 groove, vertex finely punctured ; eyes large, subquadrately 

 emarginate, the surrounding space rugose ; antennas black, long 

 and slender, third and fourth joints subequal*. Thorax not 

 longer than broad, sides nearly straight when viewed from above, 

 widened towards the apex, the anterior angles very minutely 

 tuberculiform ; the disc obsoletely sulcate near the base, the latter 

 finely rugosely punctured, the middle of the disc with a few fine 

 punctures and others anteriorly. Scutellum broader than long. 



In the original description these joints are erroneously described as equal.
