SEMASIA. 63 



third of the wing, with a triangular patch before the anal angle, and some ill-defined small 

 blotches above it towards the apex, with some fuscous streaks passing through or between 

 them from the costa before the apex towards the apical margin and anal angle. The hind 

 wings are pale brownish fuscous, paler beneath^ especially in the female : anal tuft with an 

 ochreous tinge in both sexes. 6 (5* , 1 ? . Expanse of wings 19 millims. 



I met with this species in some abundance at Camp Watson, on the John Day^s River, 

 about 70 miles from Canyon City, in Oregon, in the beginning of April 1872, and have in my 

 own collection several varieties intermediate between the two above noticed ; but the insect is 

 very plain in its colouring, and, although very distinct, is by no means a striking species. 



Semasia amphorana. (Plate LXXIV. fig. 9.) 



Palpi greyish fuscous, depressed, much widened in the middle, thickly clothed to the 

 apex, not twice the length of the head : antenna! slightly pubescent in the male ; greyish 

 fuscous: head and thorax greyish fuscous. Fore wings — three times as long as wide, the 

 costa nearly straight, with no costal fold in the male ; apical margin oblique — whitish grey, 

 almost entirely shaded with fuscoiis from the base to beyond the middle, leaving only a few 

 wavy grey streaks : beyond the middle is an ocellated mark o£ the form of a double-handled 

 bottle, extending over the entire width of the wing ; the lower half of this within the anal 

 angle is occupied by a collection of twelve rather square black dots in two groups of six each, 

 divided and margined at the sides by shining silvery scales ; the upper half is crossed by two 

 transverse greyish-fuscous lines, the short neck of the bottle opening on the costa, the margins 

 and handles being marked out internally with greyish fuscous, externally with sublustrous 

 silvery lines : cilia shining greyish fuscous : underside pale shining yellowish grey. Hind 

 wings pale brownish fuscous; cilia paler. 7^,1 ? . Expanse of wings 17-21 millims. 



Beginning of April, Camp Watson, on John Day^s Eiver, Oregon. 



This species greatly resembles Padisca dodecana of Zeller in the character of its orna- 

 mentation, especially in the cluster of black dots. The absence of a costal fold and the much 

 darker colour of the fore wings at once distinguish it. 



Semasia refusana. (Plate LXXIV. fig. 10.) 



Grapholita refusana, Walle. Cat. Lep. Het. xxviii. p. 382. 



Palpi projecting about the length of the head beyond it, together with the head rough 

 brownish ochreous ; the apical joint not exposed : antennae brownish, slightly pubescent. 

 Fore wings — with the costa slightly arched, apex rounded ; apical margin oblique, slightly 

 indented — dull cinereous ochreous, profusely irrorated with brownish scales, giving the whole 

 wing, excepting the parts adjacent to the costal margin, a dull brownish appearance ; there 

 are some abbreviated brownish streaks towards the apex alternating with silvery- grey metallic 

 lines, which are continued round the margins of the ocellated spot ; this contains five black
