P. subpicta Schs. (16 k) is a small species with black forewings exhibiting a slight leaden reflection, subplcia. 
strewn with grey, before and behind the discal area white, dusted and strewn with light brown; the anterior 
transverse line is double, filled up with light brown, the posterior line is single with short black streaks on 
the veins behind it; the ring-macula and coniform macula are very small, the reniform macula is larger, white, 
pupilled light brown; undulate line marked by the contrast of the brown subterminal area and black mar¬ 
ginal area. Hindwing dark brown with whitish or yellowish fringes. Tne under surface is rather variegated. 
Mexico (Orizaba). 
P. laudabilis Gn. (= indicans Wkr.) (16 k) is a small, light green, common, likewise very variable laudabilis. 
species; in the type the ground-colour is a rather pure light green, with dentate, white-edged transverse 
stripes and a dark blackish discal area as far as down to the submedian fold, between the maculae tinted 
ferruginous reddish. This form occurs from the United States, beginning from New Jersey, through Mexico 
to Guatemala and Costa Rica. —- A form particularly common in Mexico has the discal area darkened down 
to the proximal margin: mediosuffusa Strd. (= ab. 1. Hmps.) (16k), in which the reddish colour between the mediosuffu- 
maculae is mostly absent, though it may also be present. — Another form: rufoirrorata Strd. (= ab. 3. Hmps.) ^ ^a. 
has the whole forewing dusted and strewn with a light reddish-brown. -—- In Mexico the species is apparently 
still more variable. A form being intensely strewn with grey across the whole wing with a not darker discal 
area and absent or but quite faintly reddish discal spot- may be denominated lichcnea form. nov. (16 k); from Uchenca. 
the district of Orizaba there are particularly great numbers of it before me. — ab. scribillata ab. nov. (16 k) scribillala. 
is apparently confined to the district of Cuernavaca, it has an almost purely white ground-colour, being but 
very slightly tinted olive, the discal area not darkened and extremely fine markings, at the costal margin 
with black streaks arranged at equidistances. — From the capital there are before me very small, slightly 
built specimens taken in October and November, resembling the type in the ground-colour, but exhibiting 
very much less decorative markings, particularly the subterminal area is almost void, and the discal area is 
scarcely darkened, without a reddish macular spot: ab. egestosa ab. nov. (16 k); it may be a form of another egestosa. 
generation or also a starved form. — ab. lunata ab. nov. (16 k) is entirely white without any green or red with lunata. 
an intensely prominent, jet-black discal area with the white reniform macula in it, the ring-macula being 
absent; besides only yet a triangular dark subcostal spot and the basal marking that are more prominent. 
In numbers from Tehuacan (Puebla). — suda form. nov. (17 a) looks quite different and strange, being of suda. 
a light lilac-grey with the darkened blackish discal area of the typical form, below the submedian quite 
extinct, between the maculae with the reddish spot, all the postmedian markings indistinct, only the undulate 
line marked by small rufous spots; in numbers from Zacualpan. — From Tehuacan (Puebla) there is another 
form before me, representing an intermediate stage between rufoirrorata and lichenea: conspersa ab. nov. which conspcrsa. 
on its bluish-grey ground-colour is coarsely strewn with black and brown scales, whilst the slightly darker 
discal area is continued to the proximal margin, without any green tints, with very distinct transverse lines. 
All these forms are only single extreme types picked out from all kinds of transitions, and there might be 
quite a number of other denominations, if it were worth mentioning them; they all belong for certain to 
laudabilis. —• To what extent the variability may go is shown by an extreme lunata-iorm which we denominate: 
ab. y-nigrum ab. nov. (17 a). — The brown larva with darker dorsal spots and a light lateral line lives poly- y-nigrum. 
phagous on low plants. 
P. illaudabilis Grt. resembles a laudabilis without any green, with an entirely white ground-colour. illauddbilis. 
It was formerly ranged as a form of laudabilis , but of late it is considered to be a distinct species. California. 
P. strigicollis Wall, was formerly taken to be a synonym of laudabilis, but according to careful in- strigicollis. 
vestigations it is a distinct species. It is more slender, with narrower, triangular forewings showing a more 
pointed apex, and it never has the fine, light green colour, being mostly whitish, often tinted olive-greenish 
or moss-green; the discal area may vary from olive-brown to blackish, never with reddish tints; the trans¬ 
verse lines are rather close together, though they never converge so much towards the proximal margin. The 
hindwing is in both sexes lighter, whitish. The genital organ is different. Colorado, Arizona and Utah. 
P. marmica Schs. (17 a). Forewing white, almost entirely dusted with blackish-brown except a white marmica. 
basal spot and an anal spot; transverse lines single, the posterior line dentate, the maculae in grey rings and 
pupilled dark, the ring-macula is small and obliquely elliptical; the undulate line consists of small black 
sagittae distally bordered with white, and there is also an apical white spot, below it the marginal area is 
blackish-brown. Fringes speckled black and white. Hindwing diaphanous white, costal margin, distal margin 
and veins darkened. Mexico (Oxaaca.) 
P. ciniva Schs. (17 a) has bluish-white forewings in some places dusted with grey and thickly strewn ciniva. 
with black, the transverse lines being only double at the costal margin, the maculae finely encircled with 
black, the ring-macula small and round; the undulate line is irregular and indistinct, with a blackish streak- 
shaped spot above the anal angle behind it, with 2 white dots in it. Hindwing diaphanous white with brownish 
veins and margin. Mexico (Oaxaca). 
P. hodeya Drc. (17 a) differs from ciniva by the forewing being somewhat more mixed with brown, hodcva. 
with a black-dusted discal area only leaving free the proximal-marginal part, and a black basal ray, white 
filled transverse lines and white-ringed, brown-pupilled maculae; the undulate line is whitish with blackish 
spots behind it on the two folds. Hindwing as in the preceding. Guatemala.
