380 PROTOCRYPHIA; BRABANTIA; EUSTROTIA. By Dr. M. Draudt. 
C. pervertens B. <b McD. (52 g). Fore wing dark grey, mixed with a lighter colour, with feeble darker 
transverse lines, a dark costal-marginal spot before the anterior line, a narrow reniform macula surrounded 
with whitish and centred with 2 black dots. Undulate line indistinct. Hindwing brownish-grey. Pennsylvania, 
New York in June, July. 
C. villificans B. McD. (52 g) is similar to pervertens , of a deeper more contrasting, colouring, the 
averted sides of the transverse lines bordered with white, the anterior line more strongly notched, more oblique 
towards the inner margin, the lower half of the median area shaded somewhat brownish, with an oblique whi¬ 
tish apical shadow; undulate line more irregular. Pensylvania, New Jersey, in July and August. 
C. oletta Sdis. (52 g). Forewing red-brown in the basal half, dusted more with grey outside, a whitish 
cellular spot behind the anterior white transverse line, then follows a faded oblique red-brown median line 
with a black streak on the submedian fold, the posterior line is blackish, the oblique reniform macula is cen¬ 
tred and surrounded with whitish; undulate line faded, red-brown. Hindwing reddish-brown. Brazil. 
60. Genus: Protocrypliia B.&McD. 
Extraordinarily similar to the preceding genus from genus which it only differs in the constant pre¬ 
sence of a small areole, the lowest subcostal branch being distinctly stalked with the two next branches. 
Only 2 species which had hitherto been ranged as Eustrotia. 
P. flaviguttata Grt. (52 g). Forewing light purple brown, scantily strewn with black, with rather in¬ 
distinct transverse lines, the posterior line double, its interior portion more distinctly black; at the cell-end 
there are 2 black dots surrounded by grey, a feeble red-brown median shadow is in front of the posterior 
transverse line, spotted yellow on the median vein and with smaller spots on the inner-marginal vein; the very 
indistinct light undulate line is feebly shaded with brown inside. Hindwing greyish-brown. Florida, Texas. 
P. secta Grt. (52 g). Forewing violettish-white, dusted with purple brown, with faint dark transverse 
lines, the posterior one bordered with white outside, with 2 black dots in grey rings at the cell-end, a large 
blackish spot in the centre of the inner margin; the whitish undulate line is bordered with brown inside, with 
a larger spot at the costal margin. Hindwing greyish-brown. Massachusetts, New York. 
61. Genus: ISrsvbsuitia Dyar. 
Very closely allied to the following genus, distinguished by the origin of the middle radial branch of 
the hindwing being removed more into the centre of the cross-vein. Only one species the position of which 
has changed several times; Rothschild even described it as a Notodontid ( Dyasia ). 
B. rhizoleuca Brab. (= melanoleuca Rothsch.) (52 g) has sooty blackish-brown fore wings with a purple 
reflection, the base of the inner margin broadly purely white like the thorax; the wing is traversed by nume¬ 
rous indistinct dentate transverse lines which are broken up into dots, the double postmedian row is some¬ 
what more distinct; 2 black subterminal spots at the apex, one at the anal angle. Hindwing white with a 
blackish-brown marginal band. French Guiana. 
62. Genus: fhistrotfa Hbn. 
The genus contains numerous small species of quite the same structure as Lithacodia, but the abdomen 
exhibits only one tuft on the first ring. The genus ought to be called Erastria Ochs., since in 1826 Curtis 
fixed uncana L. as the type of this genus which had been established already in 1816, whereas Eustrotia 
Him. was only established in the year 1827. 
E. chuza Drc. (52 g) and the two following species exhibit a much longer last palpal joint which is 
just as long as the middle joint. Fore wing red-brown, dusted with purple grey, with double transverse lines, 
the posterior one extended to white and black dots on the veins, the maculae in light reddish-brown rings and 
finely surrounded with black; the whitish indistinct undulate line is shaded with a darker brown inwards. 
Hindwing reddish-brown. Mexico. 
E. mochensis Schs. ( = cassida Dyar) (40 c) we had already treated upon among the Amphipyrinae 
(p. 281), according to Dyar it belongs to this place here. 
E. pulmona Dyai with likewise long palpi is allied to mochensis. Forewing dark reddish-grey with a 
blackish, centrally angled median band, edged by the fine black transverse lines; a black dot in the centre of 
the cell, a lunula at its end; undulate line finely dentate with small light spots. Hindwing almost black with a 
lighter postmedian line and reddish fringe. Mexico (Jalapa).
