PAPILIONID^. 



The late Mr. H. Pryer informed me that in its earlier stages P. rapce, in 

 Japan, is quite typical, and the larvae feed on Cruciferse. 



Bistnhufion. Europe, North Africa, and the temperate parts of Asia. 



Genus SYNCHLOE. 

 Synchloe, Hiibner, Butler, Cist. Entom. i. p. 51 (1870). 



"Front wings subtriangular ; upper discocellular about half the length of the lower, oblique; 



lower discocellular angulated, nearly perpendicular. 

 " Hind icings. Upper discocellular half the length of lower, oblique ; lower discocellular much 



less oblique, and more or less arched. 

 " Bodi/ hairy ; palpi slender, hairy beneath ; antenusE with more or less distinct flattened club. 

 " Type S. calUdice, Esper." (Butk); I c.)

" Expands 1-50 to 1-80 in. AYings white, marked with black and grey above ; the hind wings 

 having a chequered pattern of green beneath. The tip of the fore wings is black in both 

 sexes, divided by four small white spots, each one sending an elongation into the marginal 

 fringe ; at the extremity of the discoidal cell is a black spot, in which the discoidal nervure 

 appears as a fine white line ; this black spot is narrow in the male, large and scjuare in the 

 female; the latter has also a black spot of a round or lunar shape near the hind jnargi a. 

 The hind wings are white and unspotted in the male, showing the pattern of the underside 

 through. In the female they have a black border formed of crescentie patches, with the 

 convex edge inwards, and divided by black dashes. Underside : — Pattern of the fore wings 

 the same as above, except that the border of the tip and hind margin is powdered with green 

 scales, also the discoidal spot ; the base of the wing is tinged with greenish yellow and there 

 is a l)lack spot near the inner margin in both sexes. Jlind wings green, with a slight tinge 

 of yellow, and finely powdered with black scales ; on this ground-work there is an arrange- 

 ment of white spots, disposed as follows : — Two or three irregularly placed near tlie base of 

 the wing ; outside these a row forming a band ; and again external to these, a marginal row 

 of five spots, oval or nearly ([uadrato. 



" Larva. Greyish blue, covered with small black granulations, witli four longitudinal white 

 8trij)cs, and with a yellow s\wt on each segment. The legs and ventral surface are white. 

 Clirysalis groy, speckled with black, and with reddish stripes. The larva feeds, like other 

 species of the genus, on Cruciferic and llesedacea;." (Lang, I. c.)
