12 EMMELESIA UNIFASOIATA. 



leave wiser beads than mine to determine which is the 

 cause of the other. 



The eggs were too far gone for description when I 

 had them. 



The newly hatched larva is exceedingly small, yellow 

 in colour, with a dark head. Afterwards it becomes 

 paler, of a yellowish-white, and is to look at like a 

 small maggot. 



On the 14th of October, just before its last moult, 

 I made this note of its appearance : 



Full a quarter of an inch long, and plump, but able 

 to stow itself away in a Bartsia seed-pod ; tapering 

 towards the head, and not so much towards the tail : 

 the skin smooth and glossy; the usual dots very 

 minute but distinct, being dark; the ground colour 

 yellowish-white ; the head dark brown ; plate on the 

 second segment pale brown ; a sort of pale brownish 

 plate also on the thirteenth segment, which looks 

 darker from the tubercular dots on it being black. 

 On a very close inspection one can trace the course of 

 the lines — soon to be developed distinctly, but they 

 cannot yet be described as plainly noticeable. 



Immediately after the last moult its appearance is 

 much prettier than at any other time, the ground 

 colour being of a pale delicate buff, and the lines very 

 clear and almost black ; but this contrast is soon lost, 

 the ground becoming darker and dingier, and the lines 

 paler and more diffused. 



When the larva has become full-fed the length is 

 about half an inch, the figure stout, somewhat flattened ; 

 the fourth, third, and second segments tapering rather 

 rapidly ; the head still narrower than the second, and 

 round in shape ; half the second segment scale-like 

 and shining; the hinder segments also taper to the 

 tail ; the skin is rough and wrinkled ; the tubercles 

 are dull white, furnished with short dark brown hairs ; 

 the ground colour varies in different individuals, 

 being greyish-yellow, greenish-grey, greyish-brown, or 

 brown ; the dorsal line is blackish, beginning very fine
