LEIOPLEURA PURPUREIPENNIS, new species, 
Broadly ovate, feebly convex, slightly longer than wide, broadly 
rounded in front, and nearly as broadly rounded posteriorly, moder- 
ately shining; head and pronotum bright green, the latter with a 
broad piceous area on the disk; scutellum piceous; elytra dark pur- 
ple, with the sides narrowly margined with violet; beneath piceous. 
Uead nearly flat and broadly depressed on the front, the depression 
very deep near the epistoma, but becoming obsolete on the vertex, 
with a distinct, narrow, longitudinal groove extending from the epis- 
toma to the vertex; and with a large, oblong fovea on the front sit- 
uated in the median groove; surface coarsely and rather densely 
punctate; intervals densely and very coarsely vermiculate-striolate, 
which nearly obscures the punctation; antennae rather short and 
entirely piceous. Pronotum evenly convex, three times as wide as 
long, considerably narrower in front than behind, widest near base; 
sides arcuate to near middle, then strongly, arcuately attenuate to the 
anterior angles; posterior angles nearly rectangular; anterior margin 
deeply, arcuately emarginate; base transversely truncate to near 
middle of elytron, then abruptly, arcuately emarginate and turning 
obliquely backward to the scutellum, in front of which it is truncate; 
surface with the lateral margins slightly elevated, and the dark, 
median area covering one-third of the surface, with the anterior 
angles rounded, sparsely and rather coarsely punctate; intervals 
nearly smooth on the dark area, but densely and coarsely vermicu- 
late-striolate on the green areas, the striolation nearly obscuring the 
punctation. Scutellum finely reticulate and very broadly trian- 
gular. Elytra feebly convex, as wide as pronotum at base; widest 
near the middle; humeral angles broadly rounded; sides feebly ex- 
panding to middle where they are broadly rounded, then strongly, ar- 
cuately attenuate to the tips, which are conjointly, broadly rounded, 
the lateral margins slightly elevated and obsoletely serrate; humeri 
rather prominent; each elytron with a broad, shallow depression at 
the base, and a narrow, deep one between the humerus and lateral 
margin, extending along the margin from the humeral angle to near 
the apex, broadly expanded behind the humerus, and with a broad, 
obsolete depression near the apex; surface coarsely, irregularly, 
and rather densely punctate, the punctures shallow and somewhat 
stelliform; intervals nearly smooth. Abdomen beneath sparsely and 
finely punctate, with a few very short, cinereous hairs; intervals 
finely and densely reticulate-striolate, with a few long rugae on the 
first segment; last segment very broadly rounded at apex. Pro-
