LANGSDORFIA. By H. G. Dyae f. 
19. Genus: Ijangsdorfia 
Discal vein forked in both wings; veins 6 and 7 of hindwing separated and almost parallel or at least 
almost separated. The <§ typically lacks the frenulum and the costal-marginal reverted fold, but the costal 
margin of the hindwing is very often widened, which may accomplish the same purpose of holding together 
the wings in flying. The typical forms exhibit veins 7 and 8 connected near the cell-end by a bar. Everything 
else as in Givira. 
Type: L. franckii Hbn. 
iranckii. L. franckii Hbn. (182 h). Lilac brown, lighter along the costal margin and spotted here, broadly shaded 
dark at the margin, with a thick light arcuate streak at the apex, the subterminal area lighter lilac; a dark 
shadow extends from the base through the cell; 3 or 4 silvery spots near the base towards the inner margin, 
the spot above vein 1 being the largest. Brazil and Bolivia. 
lunifera. L. lunifera sp. n. (184 d). Like franckii, but the dark median shadow is broader and despatches a wedge- 
shaped branch to the costal margin behind the middle, by which a light crescentiform spot is cut off ; the apical 
light arcuate streak is thinner and less bent. Mexico, San Salvador, Guatemala; Costa Rica; Trinidad; Vene¬ 
zuela; Colombia; French and British Guiana. Type in the U. S. National Museum. The larva, according to 
Moore, in the lower end of the stalk and main roots of “pigeon pea". 
rufitinita. L. rufitincta sp. n. (182 h) is likewise very closely allied to the two preceding species, shaded dark, the 
markings less contrasting, more or less tinged rusty brown subapically and along the inner margin; the light 
subapical spot is more quadrangular than crescentiform and less sharply defined along the lower edge than in 
lunifera of which species it may be merely a form. Mexico; San Salvador; Guatemala; Venezuela. Type in 
U. S. National Museum. 
dukinfieldi. L. dukinfieldl Schs. (182 h) is dark mouse-coloured brown with a white-dusted subterminal band which 
is angular subcostally and bends back from the anal angle to before the middle of the cell; near the base a 
dark brown bent lobate band enclosing a silvery spot; a mahogany-brown triangle at the cell-end and a larger 
one in the angle of the white subterminal line. Hindwing of $ light, of $ dark brown. Brazil and Argentina. 
adornaia. L. adornata Dgn. (184 d) differs from dukinfieldi in the whitish submarginal line not bending up to 
the cell; large whitish ringed spots behind it; the angularly lobated basal band contains a silvery spot; a narrow 
discal spot despatches a stripe outward along vein 5. Only the $ type from Ecuador is known. 
plalaea. L. plataea Schs. (184 e). Dark brown, the markings not very prominent, the veins striped light; a large 
oval silvery'spot near the base with a small one before it; silvery spots at the margin between the veins. Hind¬ 
wing without a costal convexity, but a long slender frenulum is present, penetrating into a reverted fold of 
the costal margin of the forewing. Brazil and Argentina. 
moclie. L. moche Dgn. (184 e). Blackish brown with blackish reticular markings and angled striae; an irregular 
subterminal line of spots. A large oval yellowish silvery spot near the base below the cell; inner margin red- 
brown. Hindwing light. Only the 1 $ type is at hand with a typical Langsdorfia structure. Peru. 
malina. L. malina Dgn. (184 e). Dark brown, of a variable tinge; right across the apex there is a dark brown 
triangular spot with a more apically situated dot, continued as an irregular subterminal line of spots, which is 
outwardly bordered with silvery whitish; a large subbasal spot with a yellowish silvery spot below; disc 
cloudily darkened, straightly cut off inside. Colombia; Bolivia; Ecuador and Peru. 
metcina. L. metana Dgn. ( = argentata Kohler) (184 e). Light brown, the markings distinctly prominent; as in 
malina, a large, below narrowed spot subterminally at the costal margin, continued below as a narrow line feebly 
bordered with light; a triangular spot in the disc and a quadrangular subbasal spot with an oval silvery spot 
below it on vein 1. Hindwing dark. The species is closely allied with dukinf ieldi. Argentina. 
coresa. L. coresa Schs. (184 e). Dark brown with many small darker spots; a large costo-subapical spot bordered 
with light, continued below in subterminal punctiform spots. Body very strong, the structure of the body 
typical. Colombia. 
waisoni. L. watsoni Schs. (= invetita Dgn., obscura Kohler) (184 f). Forewing brownish grey, of a variable tint 
and distinctness of the markings, the latter being brownish black; the apical spot is more or less distinctly con¬ 
tinued below as a dark, lighter bordered submarginal band; the wing slightly marked with lighter small diffuse 
spots and a few striae; a small triangular spot in the middle of the inner margin and a larger one near the
