 Plate XLII, fig. 1. 



On the 30th of July, 1872, Mr. W. H. Harwood 

 kindly sent me eggs of this species, laid close together 

 on the side of a chip box ; and he supplemented his 

 gift by a few more, which came from a correspondent 

 of his on the 8th of August, laid in clusters ; in both 

 instances some of the larvae were hatched in transit, 

 and all of them were out by the 13th. 



The egg is hemispherical, most minutely pitted on its 

 surface ; of a rather glaucous bright green colour, 

 turning olive, and again dark brown just before hatch- 

 ing ; a large hole is eaten by the escaping larva in the 

 upper part of the shell, which looks quite white when 

 empty. 



The young larva for a day or two is rather gelatinous 

 looking, of a dirty whitish tint, but soon acquiring an 

 internal pinkish tinge, showing a brown streak within 

 the thoracic segments, the head being dark brown, and 

 the body bearing some rather long, dirty whitish hairs. 

 In about ten days the first moult takes place, when, as 

 is the case with other species of Lithosice, so much of 

 the characteristic marking and colouring of the mature 

 larva is assumed, as suffices, even then, to distinguish 

 it from its congeners ; the whole larva now becomes 

 tougher in texture, and the back becomes yellowish, 

 prettily outlined with black, and with an interrupting 

 spot on the eighth segment. 



Unfortunately, I cannot give an account of the 

 appearance during hibernation; both the young larvae 

 referred to above, and those also which on two other 

 occasions I received from other friends, having died 

 whilst no more than a quarter of an inch in length. 

 However, I think that the smallest of the three I am 

 now about to describe had, when first sent to me, 

 scarcely increased in bulk since hibernation. 



Mr. Harwood, still most kindly mindful to help me
