ventral margin of the clasper. Penis-sheath (PI. LIII. f. 40) ending in an obtnse 

 dorsal Icibe, which is dentate at the end ; on the left side there is a dentate 

 longitudinal ridge, while there are onlj' a few teeth at the apical margin on the right 

 side, besides two bristles, which stand on a short process in one of the specimens 

 dissected.

The specimen figured by Boisduval and named boisdxraU. by Butler is a small 

 individual of the present species. 



The insect described by Schaufuss as ahboti is doubtless the same as cojj'eae.

(? ? . This magnificent species is apparently rare. Antenna very pale bnff. 

 Brownish black border of Lindwing gradually widening behind, very broad, touching 

 lower angle of cell ; a small black stigma; costal area of hindwing orange-rufous, 

 much more reddish than in cojfeae, ericea, etc. Tenth tergite (PI. XLI. f. 20) 

 broad and rather short ; sternite suddenly narrowed into a long, slender, feebly 

 curved hook, which is somewhat dilated near the base. Harpe similar to that of 

 stmii/i (VI. XLVII. f. 3), but slightly broader at the end. Penis-sheath 

 (PI. LIV. f. 2) with a short, rather prominent, dentate ridge at the right side; the 

 left lobe high, more prominent than in any other species, whip with teeth only 

 at the end (in all specimens ? one only examined !). No armature to peuis-fnnuel, 

 but there is a long, slightly asymmetrical, rounded, concave lobe ventrally of the 

 penis-sheath (PI. LIV. f 2).

cJ ¥ . Ground-colour of wings variable, often with a rather obvious ochraceons 

 tint. Eighth abdominal sternite with white apical fringe. Interspaces between the 

 dark lines of the forewing, above, rather obviously marked with silvery grey ; a 

 broad black patch in middle of hinder margin, widening towards base, reaciiing 

 to cell, then continued to costa by a narrower baud ; forewing below chrome- 

 yellow from base to disc, this colour gradually merging into the bright tawny 

 colour of the anterior part of the disc. Scaling of antenna, base and hook excepted, 

 very pale. 



cJ. Tenth abdominal segment similar to that of nictitans, but diiferiug 

 essentially in the triangular tooth of the sternite standing in nictitans before the 

 apical hook being barely indicated in tacita. Harpe (PI. XLVII. f. 2) truncate,
