Psyche 
[March 
densely setose above and below. Clypeus 2.5 X as wide as high, its 
apical margin weakly concave; front and vertex unusually narrow, 
middle interocular distance .48 X width of head, .93 X lower 
interocular distance; upper interocular distance only .67 X lower 
interocular, .80 X length of third antennal segment; postocellar 
line much exceeding ocello-ocular line, the latter less than the diam- 
eter of a posterior ocellus. Pronotum very broadly angulate behind; 
postnotum very narrow dorsally; propodeum with an impressed 
median line, the slope weakly transversely rugose. 
Plesiallotype . — 3, BRAZIL: same data as plesiotype except col- 
lected 6 March 1966 [Coll. H. K. Townes]. 
Description of male plesiallotype. — Length 12 mm; fore wing 11 
mm. Body yelow, marked with black as follows: spot in center of 
clypeus ; center of front from antennal sockets to vertex, then laterally 
to eye tops and back to cover much of occiput (but with yellow 
blotching in and beside ocellar triangle) ; greater part of pronotal 
slope; mesoscutum except paired yellow lines on posterior two- thirds; 
all but paired lateral spots on scutellum ; posterior margin of metano- 
tum and much of postnotum; very broad longitudinal stripes on 
propodeum, confluent at extreme base and only narrowly separated 
over much of slope; mesopleura with large lateral and ventral 
blotches and metapleura with two blotches; abdomen mostly black- 
ish, but each tergite with a narrow, transverse, subapical yellow 
band, and the sternites somewhat more broadly banded with yellow; 
antennal scape yellow, blotched with black above, following segment 
all black, remainder of antenna ferruginous below, fuscous above; 
front coxae yellow, other coxae streaked with yellow and black; 
trochanters yellow, remainder of legs streaked with yellow and 
brown; wings hyaline, lightly tinged with yellowish brown. Labrum 
weakly exserted; clypeus 1.8 X as wide as high. Middle interocular 
distance .52 X width of head ; upper interocular distance .93 X 
lower, .82 X middle interocular distance; postocellar line much ex- 
ceeding ocello-ocular line, the latter slightly less than the diameter 
of a posterior ocellus. Third antennal segment equal to about .6 
upper interocular distance. Postnotum, at the midline, less than a 
third the length of the metanotum ; slope of propodeum very low and 
even. Abdomen very slender basally; subgenital plate flat, with a 
weak median basal elevation ; parameres with a single series of five 
stout spines at the squama, the aedoeagus slightly differently shaped 
than in argentinicus (Fig. 20; see also Aide, 1947, figs. 17-22, show- 
ing the parameres in lateral view, the genitalia in dorsal view, etc.).
