not triangular, and the eyes parallel. It is also allied to Leiopleura 
Deyrolle, from which it differs, by being more robust, parallel, and 
declivous posteriorly, front of head wider between the eyes, the 
antennae more compact, and the joints not triangular. 
LEIOPLEURELLA SPLENDIDA, new species. 
Form elongate, subparallel, strongly convex, broadly rounded in 
front, feebly attenuate posteriorly, and slightly narrower behind than 
in front; surface glabrous and strongly shining; head (except the 
anterior part which is piceous), pronotum, and scutellum cupreous, 
with a strong fiery-red reflection; elytra cyaneous; beneath piceous, 
with a feeble aeneous tinge. 
Head flat on the vertex and occiput, feebly convex behind the 
epistoma, with a rather broad, shallow depression on the front, the 
depression becoming narrow and obsolete on the vertex and occiput; 
surface rather sparsely and irregularly punctate, the punctures large, 
deep, and widely separated; intervals obsoletely reticulate-striolate 
on the vertex and occiput, the striae becoming more distinct behind 
the epistoma; antennae piceous, with a slight aeneous tinge, very 
short, reaching a little beyond the anterior angles of the pronotum. 
Pronotum strongly, evenly convex, without any depressions, more 
than two times as wide as long at middle, distinctly narrower in front 
than behind, widest at the apical third; sides strongly arcuate from 
base to apical third, then more strongly, arcuately attenuate to the 
anterior angles, which are obtusely rounded; anterior margin deeply, 
arcuately emarginated for the insertion of the head; base nearly 
transversely truncate to middle of elytron, then feebly emarginate, 
and with a broadly rounded lobe in front of the scutellum; posterior 
angles obtusely rounded; surface deeply and irregularly punctate, 
the punctures widely separated on the disk, but becoming denser, 
much larger, and somewhat confluent at the sides; intervals finely 
and densely reticulate-striolate, the striae nearly obsolete on the 
disk, becoming more distinct toward the sides. Scutellum one and 
one-half times as wide as long; surface densely, obsoletely reticulate- 
striolate. Elytra strongly convex, slightly narrower then pronotum 
at base; humeral angles broadly rounded; sides nearly parallel to the 
apical third (feebly sinuate behind the humeri), then broadly, arcu- 
ately attenuate to the tips, which are conjointly broadly rounded; 
lateral margins strongly serrate posteriorly; each elytron with a 
broad obsolete depression at the base, and a similar one behind the 
humerus; surface sparsely and irregularly punctate, the punctures 
rather deep and coarse at the base, but becoming finer toward the 
apex; intervals widely, obsoletely reticulate-striolate on the disk, 
becoming strongly rugose and finely granulated at the sides. Abdo- 
men beneath sparsely, finely, and obsoletely punctate; intervals
