at the apex, and the Proharpe is much broader basally than in ncii- 

 moegeni. The Penis (PI. VI, Fig. 9) is curved; the terminal arma- 

 ture is distinct from that of ueumoegeni, consisting of 3 or 4 minute 

 teeth directly on the distal margin, each on a separate chitinous fold ; 

 behind these are two still more minute teeth situated on the outer sur- 

 face. The 9 organ (PI. VI, Fig. i) differs most prominently from that 

 of neumoegeni in the shape of the Alae, which are not pointed apically, 

 but bent over and rounded, giving a distinctly hood-like appearance to 

 the whole portion. Great care must be exercised in making prepara- 

 tions of this organ, as the chitinous fold of the inner margin of the 

 Alae is very liable to become disconnected or bent, giving an entirely 

 erroneous impression of the shape.

" $ . Head above gray, below white ; antennae black, with a few white scales 

 at the joints and white at the base of the club; body above orange-fulvous, gray 

 beneath. Primaries — Black and orange-fulvous, with a black border to the 

 exterior margin evident at the ape.x ; on the orange-fulvous inside of this border 

 is a black spot of irregular shape ; in the centre of the wing is another black 

 spot irregularly round in shape ; the base of the wing is orange-fulvous. Secon- 

 daries — Border black ; there is an orange-fulvous band which starts below the 

 costa and extends nearly to the interior margin ; the base is orange-fulvous. 

 Underside — Primaries : These are much as above, except that the upper part 

 of the orange-fulvous band is white. Secondaries — Gray, with an irregular whit- 

 ish band parallel to the costa and exterior margin ; it begins as a spot and then 

 narrows into a line and then gradually widens in an irregular way ; in the 

 centre of the wing are two whitish spots, the lower one much the longer of the 

 two. Expanse 44 mm The female is a trifle larger, but the markings are the 

 same. This species is allied to neumoegeni Edw., but is smaller and may be 

 differentiated at once by the white band on secondaries below." 



Skinner's description applies to the 9 only. We called his atten- 

 tion to this fact over a year ago when sending specimens to be com- 

 pared with the type, including both $ $ and 9 9 . We note, however, 

 that he still persists in this error in his latest compilation of original 

 descriptions. 



The $ follows the general tendency of this group in having the 

 yellow banding more reduced than in the 9 , and the yellow costal 

 spot separated from the subterminal band. Apart from its smaller
