The specimen figured by Boisduval and named boixdmydi by P>utler is a small 

 individual of the present species. 



The insect described by Scliaufuss as ahhoti is doubtless the same as coj/'eae.

<??. This magnificent species is ajiparently rare. Antenna very ])ale buff. 

 Brownish black border of hindwing 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 cojeae, 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 

 stuaiti (PI. 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 e.xamined !). No armature to penis-funnel, 

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

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

c??. Ground-colour of wings variable, often with a rather obvious oehraceons 

 tint. Eighth abdominal sternite with white ajjical 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, reaching 

 to cell, then continued to costa by a narrower band; 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. 



S. Tenth abdominal segment similar to that of iiictitans, but ditferiug 

 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.
