They were all brown in colour, two (Nos. 1230 and 1327) being 
a little paler than the rest. 
- “The first emergence took place on March 17, 1896. It is 
the female numbered 1327 in the exhibit, and resulted from 
the bright green pavonia-like larva which spun on July 27, 
making a rather light-brown cocoon. Only one more of my 
six specimens reached the perfect state, and this did not 
appear until Dec. 1, 1896. It came from the bright green 
larva which spun a dark reddish-brown cocoon on July 24, 
1895, and is the male numbered 1443. The other four 
specimens having shown no sign of emergence, I opened and 
examined the cocoons in April, 1898. Three of them (num- 
bered 1969), all dark brown, each contained a dead larva. 
The fourth (the last one to be spun) was a somewhat pale- 
brown cocoon of a curious shape, having two orifices for 
emergence, only one of which was furnished with converging 
bristles (No. 1273). It contained the cast larval skin and a 
dead pupa. 
“The four remaining examples of this hybrid now shown 
belong to that portion of the original batch which was con- 
signed on June 29 to the Hope Department. They were 
reared with the rest, as I have related, up to the fourth larval 
stage. I have no record of the time of their emergence. 
“Tt will be seen that in this form (S. schaufussi) there is far 
less difference between the sexes than in S. pavonia. In spite 
of the fact that only one grandparent is S. spinz, the influence 
of this latter species is seen both in the reduction of the sexual 
disparity and also in the prevailing aspect of the larve in their 
last stage. The difference between the male (No. 1443) and 
those which emerged in the Hope Department is very notice- 
able, A similar variability in the males of the same hybrid 
was observed by Standfuss (‘ Entomologist,’ 1900, p. 346, 
note ; and Pl. VII, figs. 6, 7). I attribute the semitranspar- 
ency of most of the specimens to the want of vigour char- 
acterising the batch generally, and showing itself in another 
way by the number of larve that failed to attain the perfect 
condition. 
“While on the subject of Saturnia I may perhaps be allowed 
to mention that a passage in Mr, Tutt’s very complete account
