Female. — Form, small, short, and feebly convex, siibopaque; head, 

 pronotum and scutellum dark aeneous, the reliefs on pronotum some- 

 what purpureous; elytra violaceous-black, basal region irregularly 

 and obsoletely variegated aeneous, viridis and cupreous, the base, 

 suture and lateral margins narrowly margined with green, the green 

 margin becoming broader on the suture posteriori}^ and narrowly 

 margined with a bright cupreous-red color along base and anterior 

 part of suture, a broad irregular gi-een premedian fascia extending 

 from the lateral margin to middle of disk, but not reaching the 

 suture, a broad post-median reddish-cupreous fascia extending be- 

 tween the green lateral and sutural margins, and a narrow preapical 

 green fascia, narrowly margined posteriorly with a bright reddish- 

 cupreous color; beneath violaceous-black, slightly aeneous in front, 

 and more shining than above. 



Head flat, with the front triangular and the sides broadly arcu- 

 ately rounded; occiput very narrow, and longitudinally carinate; 

 front and vertex without any impressions or carinae; surface very 

 coarsely and densely punctate, the punctures shallow and confluent, 

 with the bottoms finely and densely granulose, rather sparsely 

 clothed with moderately long, recumbent cinereous hairs ; eyes large, 

 strongly convex, more acutely rounded at bottom than on top, and 

 separated on the occiput by about one-half the distance between the 

 antennal cavities; epistoma broadly angularly emarginate in front, 

 with the lobes broadly rounded; antennae short, third joint a little 

 longer than the following two joints united, cupreous, and sparsely 

 pubescent. Pronotum strongly transverse, one and two-fifths times 

 as wide as long, widest near apical fourth, slightly narrower behind 

 than in front ; sides rounded behind apical angles, then feebly, arcu- 

 ately attenuate to the posterior angles, which are obtusely rounded ; 

 anterior margin obsoletely arcuately emarginate, with a feebly 

 broadly rounded median lobe; base strongly bisinuate, with the 

 median lobe broadly rounded, and truncate in front of scutellum; 

 surface evenly convex, without any impressions, rather strongly 

 transversely rugose, and rather coarsely and sparsely punctate, the 

 punctures deep and well separated; intervals finely and densely 

 granulose. Scutellum small, triangular, with the sides equal in 

 length, and surface finely granulose. Elytra" distinctly wider than 

 pronotum at base; sides broadly rounded at humeral angles, and 

 feebly expanded to just behind the middle, where they are the widest, 

 then strongly arcuately attenuate to the tips, which are separately 

 narrowly rounded; lateral margins strongly serrate to near the 

 middle; humeri not very prominent; base angularly lobed; surface
