Upper surface of hind wing. Most of the above-described mar- 

 ginal features appear, but far more faintly, on the upper surface. 

 The other orange marks are not represented on the upper surface of 

 those females that I have examined, nor did they appear anywhere 

 upon either surface of the fore wing. 



The Male of Neophasia menapia. — Under surface of hind wing. — 

 Sixteen examples were examined and of these about half had a 

 comparatively few dull orange or sometimes yellow scales in one or 

 more of areas 6, 7, and 8. When present they are precisely in the 

 position of the marginal markings of the female. 



Since writing the above I have had the opportunity of examining 

 6 beautiful specimens from Esquimalt, in Commander J. J. Walker's 

 collection. Well-developed marginal markings appeared on all 

 females: on (1) a beautiful cinnabar red; on (2) a pale cinnabar 

 red, a little deepened at the anal angle, apex, and costa; on (3) 

 orange, becoming orange-red in the same positions. Of the 3 males, 

 two possessed pale cinnabar scales at the apex and along the costa, 

 one of them bearing a few at the margin of the upper section of area 

 Ic and still fewer — only 2 or 3 scales — in the lower section. The 

 third male had pale yellow marginal scales at the apex and costa, 

 a few becoming faintly reddish, especially at the apex. 



Commander Walker tells me that these butterflies were all ''set" 

 immediately after capture, and that they have never been "relaxed" 

 and ''reset. " Inasmuch as Prof. Gowland Hopkins has shown (11, 13) 

 that the pigments of Pierince are soluble in water, it is probable that 

 Walker's specimens more truly represent the colors of the living 

 insect than do any of the others here described, for all of these have- 

 been "relaxed" at least once. 



The Male of Neophasia terlooti. — Under surface of hind wing. — 

 The marginal markings of the female menapia are represented on the- 

 male of terlooti, smaller indeed, but with a far richer color, being of a. 

 bright, rich vermilion tint. In the single specimen I have had the 

 opportunity of examining these markings are solely marginal. They 

 are wanting from area 4 and so slightly developed in all areas except 

 6, 7, and 8 (where they are purely linear and do not fill the last-named 

 area as in the 9 menapia) that it would be easy to count the con 

 stituent scales with a lens. In the specimen before me there are- 

 only 3 vermilion scales in area 5 on the left side and only 5 on the 

 right, but they are more numerous and usually far more numerous 

 in all the other markings. Although the dark pigment is com- 

 paratively weakly developed in the male, area Ic is divided ver^
