10 PROCEEDINGS OF THE NATIONAL MUSEUM VOL. 125 
Pronotum less than half as long as its maximum width (22.5:50) ; 
forelobe narrower than hind lobe (43:50), separated from the latter 
by a deep depression. Collar moderately wide, angularly incised 
anteriorly. Anterolateral angles strongly expanded, rounded and 
crenulate, produced anteriorly as far as collar. Lateral notch deep. 
Lateral borders of hind lobe rounded and crenulate. Foredisc with 
four (2 + 2) high, granulate ridges. Hind lobe roughly granulate. 
Scutellum shorter than basal width (19:26). All borders carinate, 
tip incised; lateral borders straight, almost without sinus on apical 
half; median ridge cross shaped; disc roughly granulate. 
Hemelytra reaching three-fourths of tergum VI. Basolateral border 
of corilum carinate and crenulate; apical border straight; apical angle 
rounded; all veins with a rough, setigerous granulation. 
Abdomen longer than its maximum width across segment IV (77:60). 
Midlateral glabrous areas separated from central dorsal plate by 
high, crenulate carinae. Connexivum wide and raised exteriorly; disc 
partially covered with whitish incrustation. PE angles barely pro- 
truding; PE VII rounded. Paratergites subtriangular reaching three- 
fourths of segment IX, with a large, lateral spiracle; segment IX 
slightly incised posteriorly. Spiracles II to VII ventral, on a tubercle 
far from the border, VIII lateral. 
Cotor.—Ferrugineous, partially dark ferrugineous; labium and 
tarsi orange yellow. 
MrasurEeMents.—Total length 5.72 mm, width of pronotum 2.00 
mm, width of abdomen 2.40 mm. 
Hototyer.—Female, Magdalena, Estado Bolivar, Rio Cauza, 
Venezuela, P. San Martin, 5.X.1957, deposited in the collection of 
the author. 
REMARKS.—It is a pleasure to dedicate this species to Mr. Pablo 
San Martin, an Uruguayan entomologist who collected this specimen 
and donated it to the author. 
Mezira sanmartini runs in my key (1962, p. 260) for American 
Mezira species to M. sangabrielensis Kormilev from Amazonas, 
Brazil, from which it differs by anterior process of head rounded 
anteriorly, not crenulate; by anterolateral angles of pronotum pro- 
duced forward as far as collar; by lateral notch of pronotum much 
deeper and angular; by paratergites (?) produced only to three-fourths 
of segment IX; and by setigerous granulation with distinct, yellow, 
curled hairs. 
Mezira paraguayensis, new species 
Mauy.—Elongate ovate, slightly widening backward; covered 
with a dense and fine granulation bearing extremely short setae. 
Head shorter than width across eyes (c7, 23:25; 9, 25:27). An-
