EPHIDATIA.—URACIS, 217 
Hab. Mexico, Altamira in Tamaulipas (Hoag, coll. P. P. C.: 23 g, 7 2), Lumija in 
Chiapas (coll. Westcott: 1 ¢); Guatemaa, Puerto Barrios (Hine, 0. S. U.: 3 3 ).— 
West Inpres, Cuba4~* (Poey, Loew, Baker, £c.: 33,22), Isle of Pines!?,—? Brazi, 
Santarem 8, Para §. 
Taken in March at Puerto Barrios, in June and July at Altamira. 
Hagen separated cubensis, Scudd. (specularis, Hag.®), first’ as a variety, later®* as 
a species from his own longipes, retaining the last name for the Brazilian individuals ®. 
The pair from Brazil cited above under longipes “type” differ from the Mexican and 
Cuban examples in having the frons reddish (¢) or yellowish ( ¢ ) superiorly, the 
yellow marginal stripe on the abdominal dorsum reaching back to segment 9; ante- 
nodals 9 (front) and 6 (hind wing); basal colouring of hind wing pale yellowish. 
This pair, however, are certainly immature and the colour-differences may be due 
to age. 
E. amazonica, Kirby, appears to differ from . cubensis only in having one less 
ante- and post-nodal on the front wing. It should be observed that the de- 
scription ® of amazonica is based solely on the male sex, that of Scudder on females 
only. 
I incline to the view that there is but one species of Ephidatia, without according 
any separate, even subordinate, rank to the other names. I can find no constant 
differences in the appendages and external genital organs in Brazilian, Cuban, and 
Mexican examples, especially as some variation occurs in one and the same locality, 
as our figures show.

The two species of the present fauna are separated from other, South-American, forms, which have been 
referred to this genus, by the possession of the following characters :— 
Hind wing with the discoidal triangle cross-veined, two post-triangular rows, 3-4 cells between the proximal 
subbasal sector (A, of C. & N.) and the anal margin; front wing with three post-triangular rows for at 
least part of the way to the level of the nodus ; tips to apical half of all wings brown. 
The two species may be distinguished from each other as follows :— 
Supratriangular cross-veins absent on the front wing, often also on the hind; front 
wing with 1-3 submedian cross-veins; genital lobe of ¢ less produced posteriorly ; 
vulvar lamina of Q projecting 1 mm. or less beyond the apex of the abdomen. 
Abdomen, ¢ 21-24, 2? 22-23; hind wing, ¢ 25-28, 2 25-28°5 mm. . 
Supratriangular cross-veins present on all the wings; front wing with 4-6 submedian 
cross-veins ; genital lobe of ¢ more produced posteriorly ; vulvar lamina of 2 pro- 
jecting 2mm. beyond the apex of the abdomen. Abdomen, d 25-30, 2 23°09; 
hind wing, ¢ 31-35, 9 29-8338 mm, 2. 1 6 6 6 8 ee ee tlt ts 2. fastigiata.
