to PC, and M half-way to M-, slightly curved ; a median line of bars, parallel to the 

 first, entering cell at base of R"', crossing M just before M-, with bar M- — (SM') very 

 long and parallel to M", the tawny olive interspace between these lines of bars 

 continued to discal series of bars, forming a baud of about If mm. in width which 

 is paler at ends ; median bars (SM') — SM' oblique, often obliterated ; discal bars 

 continuous, the last from R' — SM- Inniform, the line crossing R' 3 to 5 mm. from 

 M', bordered bluish white distally, followed by a continuous band (about 1 i to 

 2i mm. broad) of maroon red spots (sometimes more ferruginous red) ; spots 

 R' — SM^ Inniform, all bordered distally by the postdiscal black bars ; pale green 

 submarginal spots as above, bordered with pale silver grey, black submarginal dots 

 close to outer edge of this whitish area ; admarginal spots orange-baff, often very 

 small and ill-defined ; marginal border bistre-colour, about 1 mm. broad, much 

 narrower at anal angle, where it is nearly black ; tails with pale blue streaks.

 broader, its outer edge on the whole less concave ; tails blanter.

The species has not been bred, the larva and pupa being, in fact, unknown to 

 science ; but there is scarcely any doubt that there are two broods, which differ so 

 considerably from one another, though they are connected by all intergradations, that 

 they have been described as two species. Mr. Leech, in Butt. China L j). 127, sa3'8 

 that " the sijecies is on the wing from April to August, but the type-form appears 

 only to be found from April to June." According to the specimens that are dated, 

 the individuals with the greenish white colour of the wing extended (f. temp. 

 narcaeus) belong to the spring brood, or, as is perhaps safer to say, emerge from 

 April to June ; whUe the examples that come out later in the year have the 

 greenish white colour of the wings restricted (f. temp, mandanmis), and represent 

 most likely a second brood. The differences between the two forms are remark- 

 able in one respect. The early form narcaeus lias the black colour of the wings 

 restricted, as is the case with the sjjring broods of E. athamas, Papilio sarpedon, 

 eurypylus, etc. ; but the abdomen is much more extended black in f. temp. 

 narcaeus than in the dark-winged f. temp. 7na7idarinus, while in Eidepis athamas 

 the darker-winged specimens of the summer brood (or broods) have also the 

 darker abdomen. 



In the individuals from Central and Western China the tawny olive bauds of 

 the underside are, as a rule, more olive than in the specimens from Eastern China. 



The rows of scales on the greenish jiarts of the underside do not cover one 

 another, the green wing membrane is visible between them ; on the forewing the 

 scales of the discal greenish band are rounded at the apex, while those of the discal 

 band of the hindwing are unisinuate. 



The tenth abdominal segment of the S is broad and sinuate at the apex ; the 

 tooth-like dorsal dilatation of the clasper is generally acute.
