622 Characteristics of the Insect-Fauna 



above by the transparency of the wing. Secondaries, with 

 the basal half to a little beyond extremity of cell, a little 

 darker, and the markings of under surface appearing 

 above, as in primaries. Beneath : Primaries, marbled with 

 small narrow transverse bars, darkest toward the apex, 

 formed of blackish-brown scales, not very closely con- 

 nected ; the interspaces, at the extreme tip, white or gray- 

 ish while ; whole costal edge with short alternate black 

 and white bars. Secondaries marbled, as in the primaries, 

 but much more heavily, and with the scales of the trans- 

 verse bars black and continent ; a narrow band of white 

 scales crosses the wing in the middle, subparallel to the 

 outer border, occasionally somewhat regularly curved, but 

 most generally rather abruptly bent just beyond the tip of 

 the cell, where its rnnvx border is as far beyond the tip of 

 the cell as the width between the nervures at this point; 

 its inner border is well defined, crenate, its outer merging 

 into the marbling beyond ; crossing the wing half way be- 

 tween its base and the extremity of the cell is another 

 similar, generally less distinct, whitish band, subparallel to 

 the first; the basal half of the wing is the darkest, and 

 against the inside of the first band and the outside of the 

 second, the black bars are clustered so closely as to be 

 confluent, and form bands bordering the white bands, and 

 of nearly the same width ; beyond the outer band, the in- 

 terspaces between the black bars are more or less occupied 

 by white scales ; at the extremity of the nervures are situ- 

 ated broader black bars, which sometimes form a continu- 

 ous hind margin to the wing. 



Body black, covered with blackish and yellowish brown 

 hairs, the latter especially on the abdomen and beneath ; 

 back of head and front of thorax with many grayish 

 scales; |)alpi with long black hairs outside, shorter whitish 

 ones inside and above ; antennae brownish yellow, with a 

 line of black scales continued to the tip above, and of
