Holotype male, Madre de Dios, Peru, 500 m. (Rolle) (ZIMH). 
L. scopigera, n. sp., is closely related to enochra, in the discusssion of which 
distinguishing characters are treated. The two species may be separated from 
all others in the genus by the tuftlike cluster of large setae on the mesal 
margin of the pygofer near its apex. 
Ladoffa obscurana, NEW SPECIES 
FiGURE 285, PAGE 355 
Length of male 7.2 mm, of female 6.8-7.5 mm. Head with median length of 
crown from nine-tenths of, to one-fourth greater than interocular width, and 
from slightly less than six-tenths to two-thirds transocular width; clypeus flat- 
tened medially through part or all of its length, muscle impressions distinct. 
Male pygofer not strongly produced, posterior margin broadly and slightly 
convex, with a ventral anteapical aciculate process on each side extending 
mesad and crossing median line, with a number of macrosetae on posterior 
two-thirds of disk and near posterodorsal margin, antecosta without apo- 
demes; plates extending posteriorly almost as far as pygofer apex; style ex- 
tending posteriorly approximately as far as apex of connective which is Y- 
shaped with the arms divergent; aedeagus with shaft short and broad, ventral 
margin concave, with a pair of slender, tapering, acute, basiventral processes 
extending caudoventrally; paraphyses with a narrow, elongate stalk. 
Crown, pronotum, and scutellum brown, with a dull ivory median wedge- 
shaped mark at apex of crown; forewing black with three claval red mark- 
ings, the anteriormost slender, vermiculate, touching humeral margin, middle 
marking narrow and transcommissural, extending forward along claval suture, 
in some specimens connected with anteriormost red marking, hind claval 
marking broader and extending from claval suture to commissural margin; 
corium with three transverse red markings extending onto disk from costal 
margin, the two more anterior ones lobate, the anteriormost one connected 
with the middle claval red marking, the posterior one with a contiguous tri- 
angular hyaline costal marking before and behind and with small hyaline con- 
tiguous areoles along its margin on disk, with a triangular hyaline costal spot 
bordering middle costal red marking, with a hyaline area bordering concave 
apical wing margin; face, propleura, and legs, yellow. 
Holotype male: Tingo Maria, Peru, June 28, 1962 (W. T. Van Velzen); one 
topotypic female, February 19, 1950 (H. A. Allard); one female, Santo 
Domingo, Ecuador, July, 1964 (G. Gregoire), three females, ‘““Santarem”’, 
Brazil (USNM). One female, 2-8 miles north of Puyo, Napo, Ecuador 953 
meters, February 9, 1955 (E. S. Ross and E. I. Schlinger (CAS). One female, 
‘‘Santarem”’, Brazil, July (CM). One male and one female, Santa Cruz, 
Bolivia (J. Steinbach) (MCZ). One female, Itaituba, Brazil (RMS). 
L. obscurana, n. sp., is similar to L. scopigera, n. sp., in color and in the male 
genitalia, but differs in lacking the brushlike pygofer processes of the latter, in 
that the aedeagal shaft is shorter and its basiventral processes are not de- 
curved.
