is connected with the attarks of ground-hornbills or with some 

 other unfavourable condition ; for it is t(i be noted that the 

 females captured at Chirinda are on the whole considerably 

 larger than the bred ones. On the other hand 2 out of 18 

 captured Chirinda females in the Hope Department bear 

 distinct traces of " tails." H, I, P and are other families 

 which exhibit well-marked vestiges in single females or slight 

 traces in more than one. 



The female parent of Family D was a remarkable form, well- 

 known, although rare, in Chirinda. The first of its female 

 offspring to emerge was much nearer to leighi, Poulton, than 

 the parent or any of the 4 other offspring of this form. The 

 parent and these 5 offspring resemble leighi in the relative 

 paleness of the hind-wing patch, but the difierence between 

 this and the other markings is much less than in leighi, whose 

 fore-wing spots and patches are richer and deeper in tint. 

 The squareness of the hind-wing patch is a peculiar feature, 

 especially pronounced in the parent and two of the offspring, 

 in which the angle opposite the end of the cell is drawn out to 

 a remarkable extent. The pattern of the Chirinda form differs 

 from that of leighi in the spreading of the principal spot into 

 a triangular marking with its base along the inner margin of 

 the fore-wing, resembling but much smaller than the corre- 

 sponding feature in hippocoon and trophonius. A broad tract 

 of scattered dark scales indicates the distinction between the 

 principal spot and the rest of the marking, while the two elements 

 are almost entirely separated in the most leighi-\ike individual. 



A FAMILY CONTAINING NINE HIPPOCOON AND EIGHT DIONYSUS 

 BRED FROM A HIPPOCOON FEMALE OF PaPILIO DARDANUS IN 



S. Nigeria by W. A. Lamborn. — Prof. Poulton exhibited 

 all the female offspring together with 2 of the males and the 

 female parent, of the form hippocoon, F., captured by Mr. W. A. 

 Lamborn at Moor Plantation (480-580 ft.), 4 miles west of 

 Ibadan, S. Nigeria. The female, taken Nov. 19, 1913, ovi- 

 posited 19-23 and died Nov. 24. The whole life-history was 

 passed in the dry season, which began Nov. 5. 



Some of the pupae were exposed to cold for the periods 

 shown in the tabular statement. The conditions were described 

 by Mr. Lamborn as follows : —
