joint about half as long as the middle joint : antennae simple : head whitsh grey. Fore 

 wings — with the costa arched near the base and slightly bent downwards towards the apex, 

 but flattened along the middle; apex somewhat rounded; apical margin oblique — pale whitish 

 grey, irregularly speckled and mottled with dusky cinereous, most conspicuously so in an 

 oblique abbreviated fascia from before the middle of the costa, and a triangular costal patch 

 beyond it, the intermediate space being shaded and streaked with the same colour : some 

 minute abbreviated dusky streaks along the dorsal margin, an irregular double row of dusky 

 cinereous mottlings parallel to the apical margin, and three conspicuous black dots, two before 

 the fascia and one at the end of the cell : cilia stone-grey. Hind wings and cilia rather shining 

 stone-grey. The type figured is a female. 1 c?, 5 ? . Expanse of wings 19 millims. 

 Near Mendocino, California, June 4th, 1871. 



SciapMla basiplagana. (Plate LXV. fig. 8.) 



Fore wings lanceolate, three times as long as wide — the anal angle almost obsolete in the 

 general curve of the apical and dorsal margins — stone-grey, slightly mottled with faint greyish 

 fuscous ; a dull greyish-fuscous basal patch extending less than one fourth along the wing, 

 with a narrow streak of dull fuscous scales from the costa at its outer edge, followed by two 

 smaller streaks of fuscous scales below and beyond it, tending obliquely towards the middle of 

 the dorsal margin ; at a short interval another oblique line of fuscous streaks, each followed 

 by a faint greyish-fuscous shade, appear to indicate the direction of a subobsolete central fascia : 

 there are some faint greyish- fuscous spots along the costa. Hind wings pale brownish grey.
