acute; hindwing on an average slightly more produced to the anal angle; median shade broader, though not 
very sharply defined; outer line without conspicuous dark dots or teeth on the veins. From the least bright 
archigetes best distinguished superficially by the outer line. Venezuela, Dutch and French Guiana, the Lower 
Amazon, Pernambuco and Barra (Bahia); the type $ from Caracas, in the Tring Museum. 
P. rudimentaria Guen. {= ? calidata Walk., ? extranearia H.-Sch., ? dispunctata Moschl.) (15 b). Ap¬ 
parently one of the commonest and most widely distributed of the Pleuroprucha; but in view of recent dis¬ 
coveries of closely similar species, one wonders how many more may yet be sejDarated as a result of further 
research. For the differentiation of archigetes, protopages and hypoxia see above. More reddish than insulsaria, 
more rosy beneath, postmedian line almost without the white element, the black vein-dots generally pretty 
strong, more sinuously arranged than in insulsaria. Terminal joint of palpus short in the <$, longisli-moderate 
in the Antenna of $ much thickened towards base. Central America the West Indies and South America 
as far as Argentina and Brazil. Guenee's original pair, which I have studied, were from Haiti. Walker's 
calidata came from the Amazon and the $ which is believed to be his type otherwise fits his description so per¬ 
fectly that I think “Hind tibia with 4 long spurs” must be an unexplained lapse; the 2-spurred leg is in an 
easy position for examination and the specimen is in every way a normal rudimentaria. The type of extra¬ 
nearia was from Cuba, that of dispunctata from Surinam. 
P. rubescens Dogn. is the subject of many uncertainties, notwithstanding that. I had some correspondence 
with its author and have access to a second description, with a pencil-drawing, by Warren. The unique type, 
a from St. Laurent, Maroni, expands 21 mm and is “pale rosy, with subterminal row of black dots and some 
extrabasal vein-dots, termen finely edged with vinous, intersected at the fringe with yellowish. Forewing 
with the discocellular a little more deeply coloured, fringe more yellowish than the ground-colour. Underside 
uniform pale rosy.” Warren calls it “dull greyish pink” with the markings “greenish grey”, the median shade 
present, the two (dotted lines) placed at 1 / 5 and at 5 / 6 ; his figure (although he was generally a good draftsman) 
does not show any resemblance to a Pleuroprucha, the apex of the forewing being too rounded, the hindwing 
too long costally, etc., and might better be a small Anisodes; DoGNik, however, considered it a relative of rudi¬ 
mentaria, with longer palpus, and it may possibly have to supplant archigetes or hypoxia. Abdomen and hind¬ 
legs unfortunately lost. 
P. pyrrhularia Moschl. On this species, although he only knew a Moschler based his genus Apal- 
lacta ; but he overlooked one of the subcostal veins and failed to recognize it as absolutely agreeing with his 
own genus Pleuroprucha. Length of a fore wing 9 mm. Vertex white. Prevailing colour reddish, with palpus, 
underside of body, and the legs (except femora and tibiae) yellowish. Lines faintly dark, the antemedian on 
the forewing straightish, on the hindwing very near base, the postmedian on the forewing incurved posteriorly, 
on the hindwing angled and with fine teeth (vein-dots); median shade present. Forewing beneath lighter 
reddish, its hindmargin and the hindwing light straw-yellow; the postmedian and cell-spot show through 
faintly. Porto Rico. I added, on an inspection of the type, that veins “3, 4” of the hindwing are shortly 
stalked, not “from a point”, as Moschler gives; that the 3rd joint of the palpus is only about y 2 as long as 
the 2nd; and that the species is presumably one of the forms which are, rightly or wrongly, placed under 
rudimentaria. 
P. molitaria Moschl. (15 b), the type of the genus, has the palpus longer (3rd joint almost as long as 
2nd). Somewhat less reddish brown, the median shade slender, the lines expressed by vein-dots. Underside 
pale, the hindwing whitish, without markings. The $ antenna has its proximal part somewhat thickened. 
Porto Rico. A Pleuroprucha from Dominica is similar, but more reddish; better material is needed. 
P. roseipuncta Wan. (15 b) seems slightly narrower-winged than the more typical Pleuroprucha, gener¬ 
ally smaller, of a fleshy tinge, the terminal dots (dashes) rosy rather than grey. Antenna of J thickened at 
base, the possibility not excluded that it might be a small colour-form of ochrea, median shade perhaps more 
oblique. Venezuela to Dutch Guiana, the type series from Paramaribo, mostly in poor condition. A few $$ 
from Brazil seem also referable here. 
P. obscurior Schaus. IS mm. Light brown, irrorated with darker scales, especially on costa of fore¬ 
wing ; a dark line at end of cells; an outer row of black points on veins; a terminal row of dark spots; an in¬ 
distinct inner line on forewing”. Orizaba. Unknown to me. 
P. ochrea Warr. (15 b). Antenna of $ much thickened towards base. Paler than rudimentaria, with 
scattered irroration, costa of forewing a little darkened. Palpus much as in rudimentaria . the 3rd joint in the 
A perhaps a trifle longer. Venezuela (the type), British Guiana, Bolivia and perhaps Brazil; numerous ad¬ 
ditions to the range may be expected. — atomaria Schaus is perhaps synonymous, but as the irroration is on 
an average heavier in the Central American examples I retain the name for these. Mexico (type) to Costa Rica.
