be looked for in the same situation: — "The caterpillars, which emerge al the 

 end of May, feed on the common brakes {Pteris aquilina). When full-fed 

 their length is rather more than an inch; the ground colour of the back isolive 

 green, of the belly paler; the white body is covered with slender chocolate- 

 brown Longitudinal lines arranged in pairs; there is a double medto-dorsal 

 stripe, iiiid i luce double stripes on each side, the lowest darkest and broadest. 

 The spiracles are black, and below them is a creamy-white stripe."

5 $ and 1 9. — This is the largest species of the genus yet known from 

 this country. The wings are decidedly falcate, the costa being convex and the 

 apes acute. Body and wings pale ochreous, with a pale rusty hue. Fore 

 \\ ings with a basal curved series of discal dark dots, consisting usually of about 

 live or six venular dots — one on the costal, two on the subcostal, and one on 

 the median and internal vein each (sometimes connected, forming a wavy 

 line). A broad, rusty-brown, straight shade crosses the wing at the origin 

 of the first and second venules. A slightly-curved row of about nine venular 

 black dots; just beyond, a taint rusty shade (sometimes connected and form- 

 ing a waved line). A marginal row of intervenular dots. Fringe pale, con- 

 colorous with 'the wing. Hind wings very slightly paler than the anterior 

 pair, with an external row of about eight venular black dots. No discal dots 

 to be seen above. Beneath, four large discal dots: the extradiscal forming a 

 row of dots common to both wings. Under side concolorous with the upper 

 side of the front wings, with tine scattered scales. Legs and abdomen con- 

 colorous with the wings. 



Length of body, <?, 0.55-0.72, 9, 0.55; fore wings, S, 0.58-0.80, 9, 

 0.65; expanse of wings, 1.20—1.50 inches.

This line species differs from the others of the genus in its large size, 

 the more convex costa, and falcate fore wings, and by the two rows of dis- 

 connected dots on the fore wings, sometimes represented by lines. The 

 palpi are also a little longer than in the other species. 



Certain small individuals from California differ so much at first sight 

 from the Vancouver Island forms that they might he regarded as a different 

 species. In two specimens of the same size, from Sanzalito (Behrens) and 

 California (Edwards), the dots are connected, and form two distinct lines.
