Fetnale. — Elongate, broadly rounded in front, more attenn'ate be- 

 hind, feebly flattened above and similar in shape to angulosa Jacque- 

 lin Duval; above dull brownish-cupreous, with an obscure greenish or 

 purplish tinge; beneath aeneous, with a strong purplish or greenish 

 reflection, the tibiae, tarsi and antennae bluish-green. 



Head flat without any depressions on the front, but with a short 

 obsolete longitudinal carina on the occiput; surface coarsely, deeply 

 and densely punctate, the punctures very irregularly placed and 

 more or less confluent, sparsely clothed with very fine erect incon- 

 spicuous hairs, the intervals very irregular in shape, smooth and con- 

 vex on the top; epistoma truncate or obsoletely emarginate in front 

 and feebly lobed on each side at the antennal cavities. Pronotum 

 strongly transverse, two times as wide as long, narrower in front 

 than behind, and widest just behind the middle; sides strongly ob- 

 liquely expanded to just behind the middle, where they 'are broadly 

 rounded, then strongly attenuate to near the posterior angles where 

 they are nearly parallel for a short distance (in one of the speci- 

 mens the sides are regularly arcuately rounded), the posterior angles 

 acute and slightly projecting beneath the elytr'a; anterior margin 

 feebly arcuately emarginate, without a median lobe ; base feebly bisi- 

 nuate or nearly transversely truncate; disk broadly but very feebly 

 depressed ; surface coarsely, deeply, and rather densely punctate, the 

 punctures irregularly placed, much coarser and denser in the median 

 depression and on the antero-lateral regions, where they are also 

 more or less confluent, sparsely clothed with short inconspicuous 

 hairs, and with the intervals subopaque. Scutellum subquadrate (ip 

 one specimen it is wider than long). Elytra feebly flattened on disk, 

 declivous on the sides and about as wnde as the pronotum at base; 

 humeral angles obtusely angulated ; sides obsoletely expanded behind 

 the humeral angles, feebly sinu'ate at the posterior coxae, nearly par- 

 allel to the apical third, then arcuately attenuate to the tips, which are 

 acutely rounded, the lateral margins strongly and irregularly serrate 

 posteriorly; each elytron with 10 entire longitudinal rows of deep, 

 round or subqu'adrate punctures, which are about equal distance from 

 each other, and separated by narrow longitudinal costae, of which the 

 second and fourth are more distinctly elevated than the others, 

 there is also an additional row of finer punctures along the suture 

 extending from the scutellum to basal fourth, and not sep'arated
