HTSTRICHOPHORA. — GEAPHOLITHA. 
65 
This genus may be distinguished from Phoxopteryx, Tr., and from Steganoptycha, H.-S., 
by its longer and more conspicuous palpi^ as well as by the form of their middle joints from 
Semasia by its less oblique apical margin and almost falcate apex^ and from Pcedlsca by the 
absence of a costal fold in the male ; Avhilst the venation of the hind wings separates it from 
GraphoUtha, Tr. It seems^ perhaps, more nearly allied to Phoxopderyx than to any other 
genus hitherto characterized ; but until it may find its place in some general revision of the 
group, the peculiarities of the species under description seem to demand for it a new generic 
as well as specific definition. 
Type Hystrichophora leonana. 
Hystrichophora leonana. (Plate LXXV. figs. 2 & 3.) 
Palpi three times the length of the head, roughly clothed with long hairs projecting 
beyond the short apical joint ; tawny fawn-colour : antennaj slightly pubescent in the male. 
The fore wings — fully twice as long as wide, with the costa arched (male without a costal fold), 
the apex produced, apical margin concave, dorsal margin convex — tawny fawn-colour, paler 
towards the costa, with oblique fulvous costal streaks, the first two or three meeting at right 
angles above the middle of the wing, others less distinct running to the dorsal margin ; the 
most conspicuous of these costal streaks, which runs to the middle of the apical margin, is 
followed by a sublustrous metallic streak of equal length and by some smaller metallic streaks 
beyond it towards the apex ; the ocellated patch contains also some sublustrous metallic 
scales, and sometimes two or three black dots ; a tawny line runs along the apical margin at 
the base of the cilia, which are tipped with shining golden brown. Hind wings grey, with 
paler cilia. 4 (j" , 1 ? . Expanse of wings 19 millims. 
Var. aurantiana. 
Fore wings golden saffron streaked with golden brown, paler towards the costa. 2 
This cannot be considered a distinct species ; it differs only in colour, the shape and 
position of the markings being the same as in the type. 
The typical form occurred from the middle of INIay to the middle of June 1871, in 
Sonoma, Lake, and Mendocino Counties, California ; the bright variety in Shasta County in 
the middle of July. 
GEAPHOLITHA [H.-S.], Hein. 
GraphoUtha vitrana. (Plate LXXV. fig. 5.) 
Head greyish fuscous : the palpi short, clothed with long scales below ; the apical joint 
almost concealed ; greyish fuscous, whitish at the sides and beneath : antennae greyish 
fuscous, simple in both sexes. Fore wings olivaceous fuscous, irrorated about the middle 
with greyish-white scales, and streaked with slender greyish-white lines on the the apical 
half ; some dull white geminated streaks on the costa merging into shining brassy lines, two 
of which enclose the greyish ocellated patch with its few black scales or streaks ; the first of
