angles, basal sulcus deep and sinuate, the disc extremely minutely 
but remotely punctured. Scutellum blaclt. Elytra parallel, 
strongly punctured on the anterior portion, from the middle 
downwards their places occupied by striae. 
Length 6 mm. 
Hab. Assam : Ivhasi Hills. Type in Coll. Jacoby. 
Of uniform metallic blue colour and distinguished by the 
proportionately elongate thorax and the peculiar sculpture of the

Civ. Genova , xxvii, 1889, p. 151. 
Metallic dark blue ; antennae and legs black. 
Short and rather broad. Head with a few fine punctures, vertex 
only slightly convex, with short central 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 very 
closely placed, interstices slightly transversely wrinkled. Under- 
side clothed with short silvery pubescence. 
Length 4-5 mm. 
Hab. Coromandel; Nilgiris ; Assam; Burma; Siam; Sumatra. 
The Burmese specimens formerly named by me wallacei do not 
really seem to differ from Eabricius’ species under which wallacei 
must stand as a synonym.

Weise, Deut. ent. Zeit. 1903, p. 22. 
Metallic dark blue ; abdomen flavous. 
Head not constricted posteriorly, the neck rather swollen, intra- 
ocular space not tubereuliform, nearly plane, with a short central 
groove, vertex finely punctured ; eyes large, subquadrately 
emarginate, the surrounding space rugose ; antennae 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 
tubereuliform ; 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.
