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

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

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

 brown longitudinal lines arranged in pairs; there is a double medio-dorsal 

 stripe, and thnu' double stripes on each side, the lowest darkest and broadest. 

 The spiracles are black, and 1)p1ow them is a creamy-white stripe."

6 (f 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 

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

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

 five or six vennlar dots — one on the costal, two on the subcostal, and one on 

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

 lin(»). A broad, rusty-l)ro\vn, straight shade crosses the wing at the origin 

 of the hrst and second venules. A slightly-curved row of about nine vennlar 

 black dots; just Ijeyond, a tlxint rusty shade (sometimes connected and tbrm- 

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

 colorons with the wing. Hind wings very slightly paler than the anterior 

 ])air, with an external row of about eight venular black dots. No discal dots 

 to be seen above. Beneatli, four large discal dots; the extradiscal forming a 

 row of dots common to l)oth wings. Under side concolorous with the upper 

 side of tlie front wings, with fine scattered scales. Legs and abdomen con- 

 colorous withthi^ wings.

Tills tine species diil'ers from the others of the genus in its large size, 

 the more convex costa, and fidcate 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. 



(!erlain small individuals from C'idifornia 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 

 Calilbrma (Edwards), the dots are connected. .Tud form tv/o distinct lines.
