The species are readily distinguishable. Two of them are unknown 

 to me but apparently distinct enough from the descriptions. 



Falcaia Neumoegen, is said to have the primaries somewhat falcate 

 — an obvious distinction, for none of the other species have any approach 

 to this. The generic reference may be inaccurate. It is compared by 

 its describer to P. flava. 



Aurea Grote, is a very small species, smaller than flava, with very 

 dark primaries, the reniform white and contrasting. The secondaries 

 have the black margin to primaries narrow, and have also the costal 

 margin black — a somewhat distinctive feature. 



Flava Grote, is also a small species with more bruwni^^h primaries 

 with narrow white lines emphasizing the maculation, the median lines 

 variably separated, and with a usually somewhat faint connecting line. 

 Singula Grote, is decidedly larger and very distinctly marked. The 

 median lines are very distinctly connected by a black dash and there is 

 an oblique, black, sub-apical shade. The t. p. line has a distinct though 

 not prominent outward tooth over reniform. 



Flavidens Grote, is still larger and is the largest species of the genus. 

 The median lines are very even, somewhat approximate and with a very 

 faint connecting line, often entirely wanting. A whitish shade accom- 

 panies the t. p. line, and there is a very distinct median shade line 

 through the outer portion of median space, which is found in none of 

 the other species. 



In tabular form the scheme is as follows : 



Primaries with marked apices, sub-falcate falcata 



Primaries with rectangular or rounded apices. 



Size very small ; reniform contrasting, white, color dark ; secondaries with oslal 



margin black . aurea 



Size small ; reniform not contrasting, color more brownish, costal maigin- of 



secondaries not black flava 



Size larger, moderate. 



Median lines well separated ; distinctly connected by a black dash on subaiedian 



fold. No distinct median shade hne singula 



Median lines more approximate, even ; no distinct connecting line ; a very distinct 



median shade line flavidens 



P. falcata Naum. Papilio, 3, 141, 1883. 

 Antennse, head, thorax and abdomen light brown, with anal tuft of a lighter 

 shade. Underside of abdomen and legs of the same lighter shade. Primaries very 

 pointed at apex, then considerably bulging out along exterior margin, and rounding 

 off at inner angle. Color of same a light brown. A light transverse line from near 

 apex to inner margin ; the space enclosed between the same and exterior margin of 

 a lighter shade, darkening along the latter and showing faintly a marginal line ot ir- 

 regular dots from apex to inner angle. Another faint, oblique line from costa near 

 base to middle ot interior margin, nearly joining there the anterior transverse line. 

 A faint whitish reniform discal ring, having a larger, oblong anterior companion ring. 

 Fringes light brown.
