HTSTEICHOPHOEA. — GRAPHOLITHA. 65 



This genus may be distinguished from Phoxopteryx, Tr., and from Steganoptycha, H.-S., 

 by its longer and more conspicuous palpij as well as by tbe form of their middle joint, from 

 Semasia by its less oblique apical margin and almost falcate apex, and from Pcsdisca by tbe 

 absence of a costal fold in the male ; wbilst the venation of the hind wings separates it from 

 GrapJiolitha, Tr. It seems, perhaps, more nearly allied to Phoxopteryx tban 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 : antennae 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(^,1$. Expanse of wings 19 millims. 



Var. aurantiana. 

 Pore wings golden saffron streaked with golden brown, paler towards the costa. 2 J* . 



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 May to the middle of June 1871, in 

 Sonoma, Lake, and Mendocino Counties, California ; the bright variety in Shasta County in 

 the middle of July. 



GRAPHOLITHA (iy.-/S.), fiem. 



Grapholitlia 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
