and April 11, 1911; one collected by A. H. Jennings at Paraiso, Canal

BRACHYS CUPRIFRONS, new species. 
Female.—Broadly cuneiform, distinctly longer than wide, broadly 
rounded in front, slightly narrower behind than in front, moderately 
shining and sparsely pubescent; head cupreous, becoming reddish 
on the occiput; pronotum bluish-green, with the sides and anterior 
margin reddish; scutellum and elytra bluish-green, the latter becom- 
ing strongly cyaneous at the humeral areas; beneath piceous. 
Head feebly convex, longitudinally grooved from occiput to epis- 
toma, the groove rather broad and deep on the front, becoming 
obsolete on the occiput; surface with a few shallow, irregular punc- 
tures, the punctures more numerous behind the epistoma, but be- 
coming obsolete toward the occiput, very sparsely clothed with short, 
inconspicuous, recumbent, cinereous hairs; intervals rather densely 
granulated behind the epistoma, but becoming smoother posteriorly ; 
epistoma wide between the antennal cavities, surface concave and 
not transversely carinate in front. Pronotum strongly convex, three 
times as wide as long at the middle, distinctly narrower in front 
than behind, widest at base; sides arcuately attenuate from base to 
anterior angles; anterior margin arcuately emarginate, with a broad, 
obsolete median lobe; base transversely truncate to the elytral lobe, 
then turning obliquely backward to the scutellum, in front of which 
it is arcuately emarginate; posterior angles nearly rectangular; 
surface feebly depressed along base at middle, and with an obsolete 
depression extending obliquely backward from the anterior angles to 
the median part, without a lateral carina, finely, irregularly, and 
sparsely punctate, and very sparsely clothed with rather long, reeum- 
bent, cinereous hairs; intervals finely and densely granulated. Scu- 
tellum nearly smooth, broadly triangular, sides and anterior margin 
feebly rounded. Elytra slightly wider than pronotum at base, widest 
at basal fourth; humeral angles obtusely angulated; sides feebly 
rounded to middle, then strongly, obliquely attenuate to the tips, 
which are conjointly, broadly rounded, the lateral margins obsoletely 
serrate toward the, apex; humeri prominent; each elytron with a 
deep, rather broad depression at the base, a distinct lateral carina, 
which is strongly sinuate behind the humerus, and extending from
