Moluccas, Mangiola, and Celebes; hence f. heliconia is mndi more restricted iu 

 distrilmtion than lanceolata, a phenomeuou which, tliough very remarkable, is not 

 so rare amongst Lejndoptera; f. hclironia is a localised form of a dimorjiliic sub- 

 species, and therefore termed "f loc." (see Nov. Zool. 1895, p. 189, and 1896, 

 p. 457). 



The abdomen has a more or less complete row of black dots at the spiracles, 

 besides the dots of the ventral ])lates of the segments.

Linnfi's description of heliconia, in Miis. Lud. Ulr. at least, the figure which 

 Anrivillins gives (I.e.) of a Liuneaa specimen preserved in the collection of the 

 Queen Ludovica Ulrica, and StolFs figure of sikandia, agree very well >vith the 

 present form ; the absence of a distinct yellow area at the base of the forewiug 

 above, the very broad border to the hiudwing, of which the dlscal edge is straight, 

 and the black abdominal margin of the hindwing are an association of characters 

 with which we meet only in the present Moluccau insect, and in the forms from 

 the Solomon Islands and the Bismarck Arclii{)elago, whence Liune and Cramer 

 certainly did not have any specimens. The variability of this form is not inconsider- 

 able. The black .dots on the thorax are sometimes very large, those on the patagia 

 occupying nearly the whole patagia; the abdomen has usually a dorsal row of spots; 

 in one of our imlividuals the sjiots are enlarged, forming broad black rings. The 

 yellow basal urea of the forewing is eitiier absent, or reduceil to a short streak upon 

 the submedian nervure ; the black basal dots behind the median vein are sometimes 

 merged together to a small black patch, which is mostly conspicuously bordered 

 with a white. The median white streak of the forewing is nearly always club- 

 shaped, seldom more or less linear. The amount of black on the hindwing varies 

 considerably; sometimes the black outer border is not broader than in dicta and 

 distinctly concave in the middle, while in other individuals the border occupies 

 nearly the outer half of the wing, is straight at its discal side, somewhat dilated at 

 the nervules, and sends out to the base a black streak in the midille and another 

 beyond the cell. The imderside is iu the c? sometimes as extended black as in 

 perimele from Nias.
