16 EMMELESIA BLANDIATA. 



had reared myself ; these were about a week later in 

 their changes than the larvge of 1880. 



The egg of Emmelesia blandiata is oblong and 

 somewhat flattened, one end more rounded than the 

 other ; rather more than one-sixtieth (- 6 - -) of an inch 

 long and about one-hundredth (y^o) °f an inch wide ; 

 the shell reticulated rather coarsely and shallowly, not 

 very shining, and of a deep yellow colour ; when empty 

 the shell looks white. 



The newly hatched larva is rich yellow, with 

 blackish-brown head and narrow plate across the 

 middle of the second segment ; ifcs skin is glossy, the 

 bristles from the usual spots are somewhat clubbed ; 

 in four days' time it is decidedly grown, still yellow,* 

 and with the addition of a dark purplish-brown dorsal 

 line, and a subdorsal line rather paler than the yellow 

 ground and faintly edged with darker. After a moult 

 and increase of size the colouring is more opaque and 

 of a light buff-yellow ; afterwards a very faint brownish 

 colour tinges the back, and a slight pearly greyish- 

 whiteness the belly ; as they grow they become pale 

 dull green, with a dull purplish dorsal line ; but they 

 continue to be very plain little larvse until the last 

 moult, which is passed when the length of three- 

 eighths of an inch is attained ; at full growth the 

 length is half an inch or a trifle more, and the larva 

 is not quite so thick in proportion as its congener 

 JE. unifasciata, though the segments are plump and 

 well defined, each having two transverse wrinkles 

 near the end ; the form tapers gradually forward from 

 the seventh to the head, which is the smallest, and 

 backward a little from the tenth to the end of the 

 thirteenth. The general ground colour is green, 

 varying in richness in different individuals, and is 

 yellower and brighter for the first few days ; the head 



* The rich yellow colouring of the egg and young larva strikes me 

 as assimilating wonderfully with certain spots, apparently some fungus, 

 with which the euphrasy is much infested ; there is also a little yellow 

 grub, apparently dipterous, that shows the same colouring, but we have 

 not reared any to full growth.
