[March- June 
lar, rather convex, narrower behind than in front, feebly 
gibbous above. Head and pronotum green, with the bottoms 
of the depressions coppery red; scutellum reddish; elytra 
brown with a slight greenish tinge. Beneath, shining green 
with cupreous reflexions, the extreme tip of the last segment 
reddish, the ground of all the depressions, above and be- 
neath, clothed with deciduous, short pubescence, intermixed 
with a brownish secretion. Antennae, apex of the tibiae, and 
tarsi entirely of a bright yellow color; the rest of the tibiae 
and the femora castaneous. 
Head triangularly impressed in front, the summit of this 
impression reaching the vertex ; front separated from the eye 
by a shallow groove interrupted at the middle of its length 
and communicating with the frontal impression. Eyes large, 
a little more widely separated in front than on the vertex. 
Antennae reaching the level of the intermediate coxae. 
Pronotum nearly once and a third as wide as long ; as wide 
at the anterior margin as long. Anterior margin arcuately 
emarginate. Greatest width at about posterior two sevenths 
of length ; sides nearly straight from the anterior angles to 
middle, then arcuate, and feebly narrowed quite near the 
base. The base nearly transversely truncate ; the posterior 
angles feebly acute; the lateral margin with lateral carina 
not well defined, coarsely punctate. Disk with an entire, 
narrow, longitudinal stria at middle; a broad irregular de- 
pression along the lateral margin on each side extending 
from near the anterior margin to the base, and widest at 
the base, narrowed anteriorly, with the bottom very finely 
rugose. Behind the anterior margin, on each side, there is a 
little, finely punctured area. The disk is coarsely punctured. 
Scutellum small, smooth, shining, wider than long. 
Elytra wider at the shoulders than the pronotum at the 
base, truncate at the humeral angles; the sides nearly 
parallel to the apical third, then straight and narrowed to 
apex, with sides strongly serrate from the apical third to the 
tip, the serration becoming obsolete at the apex, the sutural 
angles feebly acute. The side of the disk with a large de- 
pression along the lateral margin, extending from the 
humerus to the tip, this depression very finely and very 
densely punctate, limited exteriorly by the epipleural carina. 
Each elytron with three elevated, parallel, shining costae, not
