440 Professor E, B. Poulton on 



It is now necessary to dcsciibc, as briefly as possible, 

 some of tlie chief features in the fore-wing pattern of each 

 of the ccnca forms : — 



Fig. 7 (No. 18) : spot (5), divided in tlie parent, is here 

 undivided : a distinct trace of (4a) can be seen on the 

 under surface. The marginal spots are much less 

 developed tlian in the parent, (y) and (8) being minute 

 and the otliers wanting: below (o) is wanting also. Part 

 of the pupal case is still adhering behind the head. 



Fig. 8 (No. 6) : (5) divided on right side, undivided 

 below : very faint traces of (4ft) and (2a) can bo made 

 out witli a lens on the under surface, (a) can be 

 made out witli a lens, (/3) minute, others small. All 

 distinct below and (y) large. 



Fig. 9 (No. 32) : (5) divided on upper surface only, but 

 the outer portion is very minute especially on right 

 side. The additional spots are unrepresented on under 

 surface, {a)-{h) well developed, (a) and (8) more so 

 than in parent. 



Fig. 10 (No. 20): (5) undivided: under surface as in 

 Fig. 9 ; marginal spots nearly as in Fig. 8. Below 

 (a) minute on left side, (^3) and (y) large, (8) absent. 



Fig. 11 (No. 14): (5) undivided: a small but distinct 

 trace of (2a) below : marginal spots absent above : 

 below {a)-{y) small and (/?) barely visible on left side. 



Fig. 12 (No. 10) : (,t) divided distinctly above and nearly 

 divided below : (4a) distinct below and a trace can 

 be identified with a lens above: (2a) wanting below: 

 (a) absent, (8) minute, others normal as in parent. 

 Below (8) absent : others normal as in parent. 



Fig. 13 (No. 17) : (5) as io Fig. 12 but the lower spot 

 is minute, especially on right side : (2a) distinct below 

 and (4a) a trace : marginal spots as in Fig. 12 except 

 that (8) is large. 



Fig. 14 (No. 23) : (5) divided on left side, fused but 

 constricted on right, below fused on both sides : (4a) 

 small but quite distinct, larger below : (y) minute, all 

 others absent, similar below except for a minute trace 

 of (/3) on left side only. 



Fig. 15 (No. 7) : (5) divided, but not below, though 

 traces of division are distinct: (4«) as in Fig. 14< but 

 rather larger: a trace of (2a) below: marginal spots 

 much as in Fig. 13, but (/:{) even more minute above, 

 and (a) absent above and below.
