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. 



" It 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 8. sjnni, the influence 

 of this latter species is seen both in the reduction of the sexual 

 disparity and also in the prevailing aspect of the larva? 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 PI. 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 

 wa y by the number of larva; that failed to attain the perfect 

 condition.

 to mention that a passage in Mr. Tutt's very complete account
