distribution of colotir. The thorax is bright coppery, with more or less 

 golden green on the disk. The elytra have the dorsal region very dark 

 steel-blue (appearing almost black) ; this blue colour making an elongate 

 triangular patch (common to both elytra), broadest at the buse, and 

 narrowing posteriorly terminates at about one-third from the apex ; next 

 there is on each elytron a broad oblique coppery red stripe (margined on 

 its inner side by golden green), commencing on the shoulder, extending 

 to near the apex (where it touches the suture), but then turned suddenly 

 to the lateral margin of the elytron ; the side of the elytron (from below 

 the shoulder to where it meets the turn of the coppery stripe) is dai'k 

 blue : the extreme apex is blue black. Length 17 J lines. '

The specimen before me agrees well with the description given (C. E. 

 Soc. Ent. Belg. 1878, p. lii) of tjis species from Sumatra. The allied 

 species has a wide range.

 Fig. 3. 



Elongate, parallel, convex, shining; black, with the elytra and legs 

 obscure pitchy, antcnnje paler. Head densely and finely granular; the 

 epistomx less opique, closely and finely punctured. Thorax with the 

 basal half parallel, very convex; the front half obliquely narrowed 

 anteriorly, sloping down, with six teeth on each margin, two anterior pair 

 slightly porrect, the space batween them emarginate. The surface pos- 

 teriorly IS marked with moderately large, deep punctures, wliich are 

 irregularly placed, the intervals irregularly and extremely finely and 

 rather sparingly punctured ; all the front part is asperate. The posterior 

 angles very slightly conically produced and diverging. Elytra of the 

 same width as the thorax, scarcely broader posteriorly, very abruptly 

 deflexed at the apex ; deeply and strongly punctured, the punctures 

 rather close together, placed irregularly near the suture, but having 

 towards the sides a tendency to form lines ; the interspaces smooth and 

 shining, less than the diameter of the punctures (except here and there in 

 the longitudinal direction, when the intervals are equal to the diameter 

 of the punctures) ; at rather remote intervals very minute punctures may 

 be seen. At the upper part of the posterior declivity, on each elytron, 

 are two short, scarcely noticeable costae; the extreme apex is slightly 

 reflexed, dull. The first joint of the club of the antennae is" a little longer 

 than broad, the second as long as broad, the third elongate-ovate. The 

 anterior angles of the metasternum, and the metasternal epipleura are 

 densely and very finely granular. The abdomen is closely and fine punc- 

 tured, and very delicately pubescent. The tar.=i are not very long as 

 compared with some of the species of this genus. Length 5 lines.
