TOETEICIDiE. 
oblique tawny fascia running to the anal angle across the apical third of the wing ; beyond it 
the costa and apical margin are spotted with pale tawny ; sometimes an oblique tawny spot 
lies across the cell at the outer edge of the basal third of the wing : vein 2 of the fore wings 
arising from the outer third of the cell. Hind wings pale fuscous grey ; the cilia paler, with 
a grey line within them. Female having much the appearance of a true Cochylis ; smaller 
than the male : fore wings narrow, the apical third much suffused with tawny ; its inner 
margin oblique from the anal angle ; a shai'ply angulated tawny fascia in the middle of the 
wing, wider towards the dorsal margin, is narrowly and obliquely interrupted at its angle ; also 
a tawny spot on the base of the costa. 
Var. «. S • Fore wings mottled whitish and very pale straw-colour; the costal fold tawny ; 
the apical fascia and basal spot obsolete ; some very pale tawny spots and streaks on the apical 
third of the wing. 5 J*, 2 ? . Expanse of wings 22 millims., ? 17 millims. 
Shasta County, California, June and July 1871. 
This species is allied to T. inopiana. Haw. [cenirana, H.-S.), Wood. fig. 1159. Heine- 
mann places centrana in the subgenus Idiograpliis of Ledercr, but confuses inopiana with hepa- 
tariana, H.-S., a true Pcedisca. Its affinities were recognized by Stephens, who classed it with 
Cochylis ziEgana and C. hamana in his genus Xanthosetia ; and Doubleday, in his ' Synonymic 
List of British Butterflies and Moths,' places inopiana. Haw. {centrana, H.-S.), in the genus 
Cochylis, Tr. I have followed them in now referring Id. fulviplicana at least to the neigh- 
bourhood of the same genus. Its structure and neuration must necessarily place it there, 
according to the rules laid down in Heinemann's synopsis, which also draw attention to its 
obvious affinity. 
Idiographis aegrana. (Plate LXVI. fig. 4.) 
Palpi white above, fawn-brown at the sides and beneath, nearly three times the length of 
the head, thickly clothed with long scales projecting below the apical joint, which is slightly 
exposed and rather pointed : head white ; antennte pale brown, slightly pubescent in the 
male. Fore wings — with the costa gently arched ; an appressed fulvous costal fold at the base — 
creamy white, faintly speckled with thinly scattered fawn-coloured scales, especially beyond 
the middle, with a fulvous dot at the end of the cell, followed by a slender line of fawn- 
coloured dots running obliquely from the costa beyond the middle to the anal angle^ above 
which it is slightly angiilated : beyond this line the apical portion of the wing is faintly 
speckled with lines of pale fawn-coloured dots ; a very slender line of the same colour at the 
base of the cilia in the fore and hind wings, more plainly visible on the underside of the 
anterior wings. Hind wings white, very faintly speckled with pale fawn-colour ; cilia white. 
Underside of fore wings much shaded with fawn-brown. 2^,2 ? . Expanse of wings 20 
millims. 
Southern Oregon, June 1872. 
This is nearly allied to the preceding species, /. fulviplicana, but is easily distinguished 
by the white ground-colour of the wings. I have seen no intermediate forms among a con- 
siderable series of varieties of fulviplicana ; and the present species does not appear to vary.
