I. hahiieli Her. A- Hopp resembles ashtabel, but the angled line is only flatly indented in the submedian 
area. Expanse of wings: $ 20 mm; $ unknown. Brazil (Amazons). A smaller specimen, not very well preserved, 
is before me from Santarem (Amazons). 
32. Genus: iPhobetron Hbn. 
Palpi much shorter, not reaching the frontal tuft, head small and hidden, in which the genus differs 
from the allied Alarodia. Both sexes very dissimilar, the $ with triangular hindwings. Synonyms are: Ecno- 
midea Westw., Spirocera H.-S., Euryda H.-S., Nemeta Wkr. 
Type: Ph. pithecium Abb. <£• Sm. 
Ph. hipparchia Or. ( = coras Stoll, variolaris H.-Schaff., bifacies Wkr., basifusca Wkr.) (16G h). $ small, 
with narrow forewings and a hyaline area in the disc, the markings of the $ covered with blackish; hindwing 
triangular, black, hyaline in the disc. the reddish ochreous ground marked with violettish grey lines, en¬ 
circling roundish spots in the cell, 2 below it and 4 behind it, separated by the veins, and at the apex. Hind¬ 
wing red, dusted blackish in the disc. Expanse of wings: $ 23—30, $ 18 — 36 mm. The larva resembles a dry 
leaf, with subdorsal rows of fleshy, hairy horns of variable length. On different forest-trees. Mexico, Panama, 
Ecuador, Colombia, Venezuela, Guiana, Brazil, Argentina. 
Ph. pithecium Abb. cb Sm.. (= abbotana Hbn., nigricans Pack., hyalinus Walsh, tetradactylus Walsh, 
nondescriptus Wetherby) (166 h). •$ with narrow and pointed forewings, the basal part with the markings of 
the $, but extensively hyaline in the disc, so that only a dark discal dot and dark scales in the basal part and 
at the margins remain. The triangular hindwing is black at the costal and inner margins, hyaline in the disc. 
The $ has a dull yellowish ground-colour with blackish brown markings bordering on the lighter spots: a con¬ 
fluent spot in the cell and two below it, dusted blackish behind it, so that the light ground is divided by finger- 
shaped stripes between the veins. Apex dark with light dusting, marginal line light. Hindwing dusted blackish 
on the red-brown ground with a light marginal line. Expanse of wings: $ 15—20, $ 17-^25 mm. The larva, 
like that of hipparchia, resembles a faded leaf and lives on various trees in forests and shrubs. Massachusetts, 
Connecticut, New York, Ohio, Virginia, Florida. 
Ph. dyari B. <£• Benj. The ^ has the same forewings as pithecium, but red hindwings, the $ is still un¬ 
known. Expanse of wings: 20 mm. Texas. 
33. Genus: Vipsorola Dyar. 
Like Euphobetron, but vein 7 of the forewing is stalked with 8 and 9. Only 1 species: 
V. semivitrea Sells. (166 i). Body robust, black; forewing pointed, hindwing quadrangularlv cut off at 
the distal margin. Disc of forewing extensively covered with very scanty scales, the margins more densely 
blackish. Hindwing except the margins quite hyaline, the black inner-marginal area broadly black. Expanse 
of wings: $17 mm. The still unknown $ probably looks very different. Guatemala. 
34. Genus: U1 am ia Mschlr. 
The $ antennae are distinguished by broad, lamellate unilateral pectinations. The veins differ little 
from those of the allied genera. Only 2 species: 
Type: U. dolabrata Stoll. 
U. dolabrata Stoll (= whitelyi Drc.) (166 h). A large, robust species, the wings lustrous and wrinkled, 
brownish yellow, the forewing shaded dark brown from the base to beyond the middle. Hindwing of $ tinged 
pinkish brown only along the inner margin, entirely pinkish brown in the 9- Expanse of wings: $ 35—42, 
^ 53 mm. Venezuela, Guiana, Peru, Bolivia. 
4 
U. sericea Schs. (166 i) differs from dolabrata in its dark shading in the disc and subterminally. It may 
not be specifically separated from dolabrata. Expanse of wings: $ 33—47 mm; ^ unknown. Peru and Bolivia. 
35. Genus: Tan;&<leiiia Dyar. 
Distinguished from Ulamia by the staff-like single, not double pectinations of the $ antennae. 
Type: T. mas Dyar. 
T. incongrua Dyar (166 i). Basal area of $ forewing dark reddish brown, purple brown at the apex, 
separated from the main colouring by an oblique lilac line. Hindwing blackish. $ not yet known. Expanse 
of wings of the $: 18—23 mm. Guiana, Brazil (Amazons).
