Hercditij in six families of Pcvpilio dardanus. 441 



Fig. 16 (No. 22): deformed: yellower spots in fore- 

 wing than any except Fig. 9: (5) divided below as 

 well as above : (4a) as in Fig. 15 : (2rt) iu two patches 

 below : submarginal spots similar to parent on both 

 surfaces, except that (a) is wanting above. 



Fig. 17 (No. 27): (5) divided and the larger portion 

 also nearly divided, so that the marking appears as 

 three sub-equal spots: below the ordinary division 

 holds and the other is indicated : (4a) as in Fig. 15 

 etc. and very distinct below : submarginal spots like 

 parent but (a) (/3) smaller and (y) (8) larger both 

 above and below : (y) below larger than (8). 



Fig. 18 (No. 24) : (5) very large, undivided above and 

 below : (4«) distinct above and below : no trace of 

 {2a) below : marginal spots very similar to Fig. 17 

 only (a) absent above and minute below. The rather 

 marked transition to liippocoon shown in this speci- 

 men has been already pointed out (p. 439). 



Fig. 19 (No. 31): much like Fig. 18 except that a very 

 slight trace of (2a) appears below, especially distinct 

 on left side : (8) absent above and below, others 

 normal on both surfaces, (a) being minute above as 

 usual. 



Fig. 20 (No. 9) : fore-wings deformed, especially on 

 right side : (5) divided on both surfaces : (4a) dis- 

 tinct below, especially on right side, absent above : 

 (2a) small on left side, large below ; on right side in- 

 visible above (perhaps due to fold in wing) ; small 

 below but evidently much concealed in fold : (y) and 

 (8) alone present above : below on left side (right 

 much deformed) (8) absent but other three normally 

 developed. 



Fig. 21 (No. 12): (5) divided above but not below: no 

 (4a) on either surface : (2a) very large both above 

 and below : (a) and (^8) can only be identified by a 

 lens, (y) and (8) are well developed and sub-equal ; 

 below (8) is minute on right side, absent en left, (a) 

 and (/3) normally developed and (y) large. 



The single hippocoon offspring. — The pattern of this 

 specimen is well shown in Plate XXIV, fig. 22. 



Fig. 22 (No. 16): (5) divided above but not below: 

 (2a) is much the largest spot in the subapical bar of 

 hippocoooi on both surfaces. (4a) is absent, for a linear
