DIRPHIA. By Dr. M. Draudt. 
I. tarquinia-group. 
D. tarquinia Cr. (= aciclalia Hbn., tarpeius Him.) (115 a) is a most variable and sexually most dimor- iarquiniu. 
phous species, at least in the male. The latter on its brown ground intensely white-haired and scaled, so that 
only an oblique basal area, a more or less large discal area enclosing a fine white Y-spot, and a subterminal 
notched band remain brownish-black. Hindwing basally and in the disc rusty brown with a black oblong discal 
spot, postmedianly more greyish-brown, turning whitish at the margin. Abdomen rusty yellow with black 
rings. The 2 is blackish-brown, basally with a pinkish grey trapezoid spot, a long creamy white discal Y and 
an almost straight, only feebly undulate subterminal line behind which the marginal area is dusted with greyish 
white. Hindwing reddish brown with a blackish discal spot. Guiana, Amazons. Bouviek describes an extreme 
variation from Venezuela; the 2 with a much lighter oblique basal band and a very light brown discal spot, 
the submarginal band is almost entirely absent; hindwing without any white marginal zone; the 2 lacks the 
greyish-white basal area and the white border line; wings dorsally very light chestnut brown. 
D„ multicolor Wkr. (= ramigera F'ldr.) (115 a, b) is likewise sexually most dimorphous; 2 with a dark multicolor. 
brown oblique basal band and inner marginal half of the median area, a very irregular basal spot and the 
harpoon-shaped discal Y whitish, the apex of the latter black, projecting far beyond the undulate postmedian 
line; costal-marginal portion of the median area, and distal margin light brown, behind the postmedian line 
more or less broad pinkish-white, veins 6 and 7 with a few thick black dots. Hindwing pinkish-brown, basally 
darker pink, with a black discal oval or spot and 2 brown transverse bands behind it. Abdomen black with 
narrow reddish-yellow rings. The 2 looks very much like that of tarquinia , but it is at once discernible by the 
light costal-marginal part and the differently shaped, more pinkish-white basal spot. Hindwing basally 
intensely dark pink, abdomen with much narrower reddish-yellow rings. Brazil. brasiliensis Bouv., described brasiliensis. 
according to a very large 2 with an expanse of 135 mm, from Brazil, probably belongs to this place here; 
according to the description there seems to be only the difference that the discal Y does not extend to the 
subterminal line. 
D„ horcana Schs. (115 b) is much smaller, basal area with creamy white scales, produced in long dents horcana. 
to the centre of the costal margin and of the inner margin, and brownish before the distinct border line, striped 
brown on the costal marginal veins; median area brownish-black with a narrow fine discal Y, distally defined 
by a straight postmedian line which is distally narrowly bordered with brown, traversed by creamy white veins: 
marginal area likewise creamy white, dusted with brownish, with a notched subterminal line forming dark 
brown notched spots between 2 and 3 and below the costal margin. Hindwing bright rusty yellow, at the 
margin greyish-white, with 2 greyish-brownish subterminal arcuate lines. In the larger 2 the basal and marginal 
areas are pinkish-brown, the creamy white discal Y-spot reaches in the type brevifurca Bird, neither the ante- brevifurca. 
median nor postmedian line, whereas in another specimen it reaches both. Costa Rica, Ecuador, and Colombia. 
In a male specimen from Villavicencio the blackish-brown median area is very narrow, the light basal spot 
extends at the costal margin with its apex beyond the postmedian line, the hindwing is intensely dusted with 
greyish-brown; it is probably only an individual variation. 
D. horca Dogn. (115 c) is very similar to horcana , but the light basal spot does not form any distal horca. 
notch at the costal margin, but bends subcostally still farther basad; subterminal line distally very slightly 
concave; the discal Y is much thicker, particularly the cross vein branch which contains an ochreous central 
streak. Hindwing redder, otherwise marked the same. The 2 is similar to that of horcana. Ecuador; Venezuela; 
1 e Coll. Bang-Haas is labelled “Mexico”; South-Western Colombia (Putumayo). 
D. subhorca Dogn. is exactly like horca, but the brownish-black median area is equally broad at the subhorca. 
costal and inner margins, the hindwing exhibits a small black discal spot, and close behind it a postmedian 
line, both being absent in horca. Expanse of wings: 73 mm. Paramba (Ecuador), described according to a 2- 
D. aculea Vuill. (115 c) <2 light pinkish-brown with a narrow brownish-black median area not reaching aculea. 
to the inner margin and containing a fine creamy white Y, and traces of a mottled subterminal line which is 
only more distinct between 2 and 3; marginal area slightly darker. Hindwing pinkish-brown with a small darker 
discal spot and a reddish-brown postmedian line. The 2 is very similar to that of tarquinia , but much smaller, 
with more pointed wings, basal and marginal areas pinkish-brown, basal area much more extensive; the discal 
Y does not reach to the postmedian line, its upper branch bears a fine"'brownish-black central streak. Amazons: 
Eastern Colombia (Upper Rio Negro). 
D. lombardi Bouv. (115 c) is a smaller species, very similar to the following species and perhaps only lombardi. 
a form of it; the oblique pinkish-grey basal area has distally a convex border, the dark brown median area is 
at the costal margin twice as broad as at the inner margin, the Y similar as in the preceding species, the upper 
branch centred brownish-black. Marginal area proximad pinkish-white, distally brownish with a notched 
subterminal line which begins very dark and intense at the costal margin, so that a light oblique streak parts 
the apex, and vanishes more or less in the centre. Hindwing very thinly scaled greyish-brown with a fine discal 
streak and a slightly darker postmedian line. Abdomen black, dotted white, at the anus reddish-yellow. 
Parana; Minas (Southern Brazil).
