oblique streaks, lightest on the costa. A streak of bUick begins on apex, 

 and proceeds parallel to costa to about middle of cell, interrupted at half 

 its length. An obscurely black streak on median line, between basal patch 

 and inner third, a few black scales overlaying white patch on dorsal 

 margin before inner third. Outer margin and cilia dark fuscous, a black 

 dash in cilia just below apex. Hind wing dark smoky-brown, cilia darker. 

 Under side fore wing dark smoky-brown, cilia lighter ; five geminate 

 whitish spots on costa. Under side hind wing and cilia fuscous. 

 Abdomen, upper side same as thorax, black, with a few very minute 

 brown specks, anal tuft purplish brown. On the second or third 

 abdominal segment is a flattened tuft of long scales. Under side of 

 abdomen and legs light fuscous, latter annulated with black vand speckled, 

 same as upper side of abdomen and thorax. 



Protopteryx Columbia, var. intdiostriana, var. nov. — Head brown, 

 mixed with lighter and darker scales, mottled. Palpi mottled-brown 

 outside, nearly white on inside and apex. Thorax smoky-black, very 

 minutely speckled with brown ; patagia with white spot on posterior end. 

 Fore wing, ground colour very uniformly mottled bluish-grey, fuscous and 

 black scales, with a few brown scales in patches and streaks. Beginning 

 at base on median line and extending to outer margin just above 

 anal angle is a pinkish fawn-coloured streak, slightly wider at outer 

 end ; a second streak of this same colour begins at base, but only extends 

 to inner third, below and parallel to the long one, they are joined together 

 at base. A number of geminate whitish dots on costa. Hind wing smoky 

 fuscous, cilia fuscous. Under side, fore wing smoky fuscous, with geminate 

 whitish dots repeated on costa. Hind wing fuscous, darker before apex. 

 Abdomen very dark fuscous ; under side paler. Legs fuscous. 



Described from about 60 specimens, of which ten per cent, are var. 

 albidorsana and the same number var. mediostriana. Bred by Dr. Dyar, 

 Kaslo, B. C, on willow (?), and collected by Dr. Taylor, Wellington and 

 Vancouver, B. C. and by Mr. Bryant, Wellington, B. C, latter part of 

 February to latter part of March. U. S. Nat. Mus. Type Nos. 7789, 

 7790 and 7791, respectively. 



This species is nearest to the European Protocpteryx crenana, Hbn., 

 inasmuch as both are extremely variable ; all of the British Columbian 

 specimens are larger than crenana, the general colour of the latter is 

 brighter and less sombre, and the hind wings oi crenana decidedly lighter. 

 I have no knowledge of the variety mediostriana occurring at all in Europe. 



Named in honour of the earnest and hard-working Entomologists of 

 the British Columbia district.
