70 XANTHOXENA: CATHYDATA; CHLORACTIS; DICHORDOPHORA; MEROCHLORA. By L. B. Prout. 
42. Genus: Xantlioxena Wan. 
Of this genus also the $ is unknown and its actual relationships are further obscured by a mimetic 
resemblance to the Cyllopoda group. Eye small; palpus moderate; antenna strongly pectinate; hindtibia with 
terminal spurs only; abdomen not crested. Venation nearly as given under Dyscheilia, but the 2nd subcostal 
arises beyond the 5th (in Dyscheilia normal) and the 1st median of both wings is stalked. 
X. imitans Wan. (8 k). Absolutely distinct in its bright gold-yellow colour and black borders. Ecuador: 
Gachabe, low country, only the 3 originals known. 
43. Genus: Catliydata Prout. 
In this genus and those which follow, perhaps also in one or both of the preceding, the frenulum is 
wanting not only in the $ but also in the J. For the rest, Cathydata has mainly the characters of Neagathia, but 
with longer palpus (in the $ exceptionally long), still more hyaline wings (recalling the Hydata group), deeper 
excision in the hindwing and very peculiar discocellulars, which form two separate, outwardly oblique curves, 
the 3rd discocellular arising far distallyof the 2nd, especially on the hindwing; 1st median of both wings generally 
stalked. 
C. batina Druce (8 k). Easily known by the shape and markings. Described from Guatemala, but reaches 
Peru and Venezuela. — schadei subsp. nov. (8 k). Thorax posteriorly and abdomen at base infuscated above; 
wings slightly less elongate, especially the hindwing at the 3rd radial; all the markings darker and more opaque, 
particularly the basal patch and the thick postmedian line. Brazil: Blumenau, Santa Catherina, 26 April 1929 
(F. Schade), type <$ in coll. Joicey. Although 1 have seen few other schadei , the general constancy of batina 
in Tropical America leaves no doubt that this is a good race. 
44. Genus: Cliloractis Wan. 
Near Cathydata, which might possibly be sunk to it. Differs in its less elongate palpus, lack of con¬ 
cavity in the termen of the hindwing and in having the discocellulars normal or — in the genotype, pulchenima - 
with the 3rd strongly incurved. 
Ch. tanaoptera Prout (8 1) recalls a semihyaline, long-winged Phrudocentra, but the loss of the <$ frenu¬ 
lum necessitates its being placed here. The heavily bordered, but otherwise little clouded wings, as well as 
the shape, distinguish it readily from the following. French Guiana (type) and Lower Amazon. 
Ch. obnubilata Wan. (8 1). Shorter and broader winged than tanaoptera, postmedian line of hindwing 
straight, posterior part of forewing and nearly the whole of hindwing dark-clouded above and especially beneath. 
Guianas and Amazons, the type from French Guiana. 
Ch. pulcherrima Bull. (8 1). Strikingly distinct in its pattern, particularly the strong longitudinal lines 
of the distal area. Widely distributed: Trinidad, Colombia to French Guiana, and a very extensive area in 
Brazil, even reaching Joinville; the type from the Brazilian Amazons. 
45. Genus : Dichordophora Prout. 
Coloration and pattern of Dichorda, from which it scarcely differs radically except in the absence of 
the C frenulum. The two known species form separate sections, the proximal spurs of the hindtibia being 
present in aplagaria, wanting in phoenix. Both belong to subtiopical North America and seem very closely related. 
D. aplagaria Dyar (8 1). Very similar to phoenix, 3rd joint of palpus in $ perhaps a little longer, hind¬ 
wing with abdominal margin longer in proportion to costa; costal ornamentation rather broader, lines perhaps 
rather straighter. I have not seen the 9- Mexico (type) and Guatemala. A transition between Dichorda and 
Dichordophora. 
D. phoenix Prout (8 1). The type of the genus and so far as is at present known its only represen¬ 
tative in the United States. For the distinctions from aplagaria see above. Antenna of $ pectinate. Arizona. 
46. Genus: Merochlora Prout. 
Related to the first section of Dichordophora but somewhat different in shape, tone of colour and mark¬ 
ings and characterized by having the costal vein of the hindwing anastomosing with the subcostal to beyond 
the middle of the cell. North American. I have no knowledge of the early stages.
