220 EMBRIK STRAND, 
Length 20 mm. 
1 specimen taken at Asuncion in April. 
Plesia notabilis n. sp. 
9. Clypeus convex, closely punctured, with a smooth line from the 
base to the apex. Head shining, the front rather sparsely punctured, 
the space round the ocelli and the vertex very sparsely punctured, the 
punctures large and with rather long fulvous hairs. Pronotum and 
scutellum strongly but not very closely punctured, the mesonotum 
with a few scattered punctures. Median segment opaque, obscurely 
rugose, transversely striated at the extreme apex and on the face 
of the posterior truncation, an impressed line broadest at the apex 
and not reaching the base on each side before the base of the 
truncation. Propleurae shining, indistinctly obliquely striated, meso- 
pleurae strongly, but not closely, punctured, the sides of the median 
segment strongly obliquely striated. Abdomen shining and almost 
smooth; the pygidium closely longitudinally striated, rather broadly 
rounded at the apex. The first and second abscissae of the radius 
are of about equal length, longer than the third; the recurrent 
nervures are received a little beyond the middle of the second and 
third eubital cells. 
Black; a broad transverse band above the antennae reaching 
the eyes, a band on the posterior margin of the head exten- 
ding onto the lateral margins behind the eyes, the posterior 
margin of the pronotum broadly, a triangular spot on the 
mesopleurae beneath the anterior wings, the postsceutellum, a broad 
transverse band slightly emarginate anteriorly at the apex of the 
first abdominal segment, the sides of the second segment broadly, a 
transverse band strongly narrowed at the junction with the lateral 
bands at the apex of the same segment, the three following segments 
similarly marked but with the lateral bands not extending so far 
towards the base, a spot at the apex of all the femora and a line 
on the anterior tibiae yellow; mandibles, except at the apex, legs, 
except the coxae, trochanters and basal half of the femora, and the 
apex of the pygidium dark ferruginous. Tegulae testaceous, yellow 
at the base, with a very short yellow line above them. Wings very 
pale fusco-hyaline, darker along the costa on the apical half of the 
primaries; nervures testaceous, fuscous at the base. 
Length 17 mm.
