Leptolopha. Warren, Novit. Zool. Vol. 16, p. 78 (1909). 
Characters. — Face smooth. Palpus in cf rather short, in Q rather long, second joint rough- 
scaled below, third joint smooth, in c small, in 9 elongate, slender. Tongue present. Antenna in c 
bipectinate with moderate or long branches, apical one-third or less nearly simple, in Q nearly simple 
or strongly bipectinate. Pectus somewhat hairy. Hindtibia in both sexes with terminal spurs only. 
Abdomen with rather weak, soft, non-erect dorsal crests. Frenulum in c slender, from before basal 
expansion, in Q wanting. Forewing with costa very slightly arched or almost straight, apex moderate, 
termen smooth, oblique, slightly curved, cell rather short, DC incurved, SC! free, SC? normal. 
R! stalked, M! connate or shortstalked; hindwing with termen little convex, tornus pronounced, cell 
short, DC? incurved, C approximated to nearly one-half cell, SC? stalked (very long-stalked in Section I), 
M! short-stalked. 
Early stages unknown. 
A small genus, almost certainly associated with the group of genera following, though with the 
dorsal crests much weaker (especially in Section II). There is some superficial resemblance to some of 
the more slenderly-built species of Racheospila (Section Lissochlora), with which Warren compares it; 
but the loss of the median spurs, and in Section II the pectinate Q antenna, show the greater advance 
in specialization. 
Type of the genus : Leftolopha flavilimes (Warren) — Lissochlora flavilimes, Warren (1909). 
Geographical distribution of species. — Peru, Brazil. 
SECTION I. — Dorsal hair forming definite crests; cells quite short ; 
Q antenna not bipectinate.

1) Dichorda (? phoenix, nov. sp. — 9,27to 32 mm. Face crimson above, white marked with crimson below. Palpus crimson, somewhat 
mixed with white, base white beneath ; terminal joint more slender than in the other species. Antenna bipectinate with short, slender branches, light, 
ochreous, shaft white dorsally. Vertex white, occiput green. Thorax green, somewhat mixed with white beneath Abdomen white mixed with green, the 
dorsum wholly green basally, gradually giving place to more ofthe white colour. Forewing with termen somewhat less oblique than is typical in the genus, 
suggesting 42/7odes; bright emerald green, costa narrowly crimson, interrupted with white; lines white, broad, antemedian from a slightly thickened spot 
at costa at nearly one-third. almost straight (insignificantly outbent in middle) to inner margin at beyond one-third ; postmedian from costa at nearly three- 
fourths, parallel with termen (in the co-type very slightly curved basewards at costa); discal dot extremely minute (dark) or wholly obsolete , fringe green 
proximally, white distally. Hindwing with costa longer than in typical DicZorda, C approximated to cell to well beyond one-half; concolorous with fore- 
wing; only the costal area somewhat whiter; antemedian line wanting, postmedian nearly straight or very slightly curved, from costa nearly opposite 
postmedian of forewing to inner margin ator beyond tbree-fourths; discal dot and fringe as in forewing. Underside paler, similarly but more weakly 
marked. Phoenix, Arizona, 13 Sept. 1904 (R. E. Kunze). Type and co-type (both Q) in coll. Brit. Mus. Scarcely a true DicAerda, according to the 
differences noted above; the non-oblique postmedian line of forewing also gives it a somewhat different aspect (more as .42/odes) ; but the frenulum is 
absent, the legs and palpi almost sufficiently bairy, and it can remain here for the present. In the type, SCt of forewing is free, in the co-type it anasto- 
mosSes moderately with C.
