tation; antennae rather short and piceous, with the basal joints 
slightly greenish. Pronotum moderately convex, two times as wide 
as long, narrower in front than behind, widest at base; sides nearly 
parallel to apical third, then arcuately attenuate to anterior angles; 
posterior angles distinctly projecting and rather acute; anterior 
margin feebly, arcuately emarginate; base transversely sinuate to 
middle of elytron, then turning obliquely backward to the scutellum, 
in front of which it is obsoletely sinuate ; surface narrowly depressed 
along the sides, and with a broad, transverse, concave depression 
along the base, with an obsolete sinuate lateral carina extending 
from the base to middle, and nearly parallel to the lateral margin, 
finely and sparsely punctate, the punctures very shallow and stelli- 
form; intervals finely, obsoletely punctate, and obscurely reticulate, 
becoming densely and coarsely granulate-striolate in the green areas 
at sides. Scutellum smooth and triangular. Elytra feebly convex, 
slightly narrower at base than pronotum; humeral angles obtusely 
angulated; sides feebly sinuate behind humeri, slightly expanded at 
middle where they are equal in width to the base, then strongly, arcu- 
ately attenuate to the tips, which are conjointly narrowly rounded, 
the lateral margins rather strongly serrate; humeri moderately 
developed, and extending nearly to the lateral margin ; each elytron 
with a broad, rather deep depression at the base, and a broad, shal- 
low one along the lateral margin behind the humerus ; surface feebly 
wrinkled near the base, coarsely, irregularly, and rather densely 
punctate, the punctures somewhat confused at the humeral regions, 
but becoming more obsolete toward the apex; intervals smooth. 
Abdomen beneath densely and finely reticulate-striolate, with a few 
long, widely separated rugae on the first segment; last segment 
broadly rounded at apex. Prosternum sparsely punctate, the 
punctures obsolete anteriorly, but becoming very coarse on the 
prosternal process ; anterior margin truncate. Metasternum sparsely, 
obsoletely punctate, with the intervals densely reticulate-striolate, 
and with long, widely separated rugae on the median part. 
Length, 2.75 mm.; width, 1.25 mm. 
Type locality.—La Ceiba, Honduras. 
Type and paratypes.—Cat. No. 25130, U.S.N.M. 
Described from four specimens collected by F. J. Dyer August 23, 
1916. 
This species is rather variable in color. Paratype “a” is more 
violaceous on the elytra than the type; paratype ‘‘b” has the head 
cupreous, with a strong violaceous tinge on the occiput, pronotum 
without the green margins, and the entire upper surface strongly 
violaceous; paratype ‘“‘c’”’? has the head green, pronotum without 
the green margins, and the entire upper surface more piceous than 
in the type.
