new species of North American Tortricidx, 509 
Psedisca invicta, sp. n. 
AntenncB biciliate (1) in the male ; greyish ochreous. Palpi 
fawn greyish at the sides, whitish above and beneath ; the apical 
joint almost entirely concealed in closely appressed scales. Head 
fawn-brown. Thorax whitish, with a pale pink suffusion. Fore- 
wings white, mottled with pale leaden grey, except on a broad 
quadrangular medio-dorsal patch, the grey mottling is more con- 
centrated around the margins of this patch and before the upper 
half of the apical margin than on the other parts of the wiog ; the 
quadrangular white dorsal patch has its inner edge almost straight, 
a narrow pale fawn-brown line studded with groups of black scales 
separating it from the grey mottled space which precedes it, its 
outer edge is somewhat angulated, reducing its width above the 
fold, here also it is bounded by a slender fawn-brown line and a 
series of black dots ; the slight fawn-brown shade beyond it 
precedes a curved line of black dots indicating the inner margin of 
an obsolete ocelloid patch, and beyond this, parallel with the 
middle of the apical margin, are three or four small black lunules 
with some pale fawn-brown scaling which is repeated in an oval 
spot at the extreme apex ; cilia rosy white, a grey line at their base 
around the apex, and three grey spots about the middle of the 
margin. Exp. al., $ 30 mm. ; 33"5 mm. Hindwings greyish 
fuscous ; cilia white, with a dividing shade near their base. 
Abdomen ^YQji^h. Xe^s white.

The description is taken from an extremely fine and 
well-marked specimen, but two varieties occur which are 
at least worth mentioning : in both, the lines of black dots 
are obliterated and the grey mottling is much less dis- 
tinguishable, in one the whole wing is suffused with rosy 
pink as in fine specimens of the European Psedisca incar- 
natana, Hb., in the other there is but the faintest 
indication of the darker markings, the white ground- 
colour prevailing throughout. 
Pssdisca (?) carolinana, sp. n. (PI. XII., fig. 5.) 
Antennce finely ciliate ; greyish fuscous. Palpi (broken). 
Head purplish fuscous, mixed with grey brown scales. Thorax 
purplish fuscous, posteriorly tufted with ferruginous and grey
