radial, but more particularly at the 1st. The group is exclusively Central and South American. Of the early 
stages nothing is known. 
P. completa Dogn. “31 mm. Semihyaline, pale greenish yellow, the markings pale violaceous grey: 
an antemedian and postmedian, both fine, rounded and dentate; a broad subterminal band of irregular extent, 
rounded. In addition, some rounded discal spots, twice as large on the forewing and, on this wing only, a 
rounded subbasal band.” Quindiu, Colombia, at 3500 m, only the type $ known. Much larger than the other 
species, yellower than most. 
P. benepicta Warr. (8 g). Distinguished by the broad and bright outer band, which becomes violet- 
grey on the forewing anteriorly. Fonte Boa, 1 Besides, I only know a from S. E. Brazil (Mus. Wien). 
P. aurata Dogn. Closely related to brunneopicta (8 g), similar in shape and in its yellowish, iridescent 
ground-colour, as well as the general scheme of the markings; these, however, are more green, the subterminal 
band dentate proximallv, connected with the terminal so as to leave only spots of the ground-colour, on the 
forewing in cellules 5, 4, 3, 2 and at tornus, on the hindwing (which, moreover, is less heavily clouded) in cellules 
7, 6, 5 and 4. Colombia: San Antonio, near Cali. 
P. brunneopicta Warr. (8 g) from Carabaya, S. E. Peru, is easily recognizable from our figure. A specimen 
from Cushi, Huanuco, is somewhat transitional towards aurata in the form of the outer band. 
P. ignita Prout (5 k), founded on a $ from Cachi, Costa Rica, may possibly prove to be the $ of the 
following, but looks very different on account of the broader reddish costal suffusion and the extended dark 
cloudings of the forewing. 
P. busa Druce (5 i) is unknown to me, but will be easy to distinguish from most Prohydata <$<3 by the 
absence of the apical patch of the forewing and presence of costal stripe. Chiriqui. 
P. stigmatica Warr. (8g). Quite unlike all other known Prohydata. From Hydata scripturata, even 
the most heavily marked aberrations differ in their brighter green colour, less black lines, etc. Costa Rica 
(type) to Peru. Its systematic position is, however, somewhat problematical, as a few scarcely distinguishable 
specimens have the venation of Hydata. 
P. pellucidaria Dogn. should be distinguishable from the species of the following group by the stronger 
cell-spot of the forewing and the reduction and weakening of the other markings; in particular, those of the 
hindwing merely form two spots along the abdominal margin, from which spots there arise sinuous lines, parallel 
to the distal margin. Loja, S. Ecuador, 3 — versifusa form. nov. (8 g), determined by Mr. Warren as 
pellucidaria, may be a race of that species (with which I am not able to compare it), but in any case not a syno¬ 
nym. More strongly marked, the two lines of the hindwing thick, but obsolete anteriorly, on the underside 
distinct, but on the upperside almost entirely obliterated by a large dark cloud. Carabaya: Tinguri, 3400 feet, 
the type (J; Santo Domingo, 6000 feet, 2 <$<3 ; all in the Tring Museum, collected by Ockenden. May probably 
prove a species; distinguishable from the following group by the clear green costal area of the hindwing. 
P. digma Dogn. (8 g) differs from the rest of the group in having a semicircular terminal patch of the 
ground-colour on the posterior half of the hindwing. We figure the only Bolivian example available, although 
its hindwing is slightly discoloured proximally and has the dark distal part somewhat less extended. Besides 
this, the type locality, digma is known from S. E. Peru. 
P. latifasciata Warr. ( = dicata Dogn.) (8g) was described from the $, in which the forewing has 
a complete subterminal band, at least 3 mm wide, connected with the margin in cellule 3; the <^, which we 
figure, is extremely similar to those of some of the allies, but (like the $) is best known by the very obliquely 
bounded basal patch of the forewing. S. E. Peru. The type of dicata Dogn., which I confidently sink, was a 
d 1 from Bolivia. 
P. povera Schaus (= satisfacta Druce, nec Walk.) (5 k). Sexual dimorphism about as in latifasciata, 
the band of the forewing in the $ almost reaching the termen except near the apex; basal patch at least as 
broad at costa as behind. Described from Mexico, but reaches Venezuela and Trinidad. 
P. projiciens Front (8 h) is rather larger, weakly marked and may be regarded as blending the characters 
of the 3 preceding species; basal patch nearly as oblique as in latifasciata (8g), but less regular; cell-mark of 
forewing as weak as in this and in povera, that of hindwing strong; border of hindwing nearly as in digma. 
W. Colombia (loc. typ.) and Peru. 
P. popayanaria Dogn., of which the $ type, from Popayan, remains unique, is also relatively large 
(22 mm from tip to tip); yellowish green, the forewing with the lines irregular, darker, the subbasal fine, not 
bounding a dark patch, the subterminal anteriorly thickening and sending out two streaks to the termen, so 
as to recall the markings of the 4 preceding species; hindwing with the central part darkened and with a vague, 
rounded subterminal line.
