THE LARVAE 



OF THE 



BRITISH MOTHS. 



Cymatophora duplaris. 

 Plate LIV, fig. 3. 



On the 12th September, 1869, Mr. George H. 

 Kenrick, of Inverhadden, by Kinloch Rannoch, kindly 

 sent me eight examples of the larva of this species, of 

 different sizes. 



This larva, when full fed, is about seven-eighths of 

 an inch long, moderately stout and cylindrical, the 

 head rounded. 



The ground colour a pale and dull olive green, 

 deeper in tint on the back, with a dorsal pulsating 

 stripe of dingy olive green ; the subdorsal stripe very 

 broad, of a dusky olive, sharply defined at its lower 

 edge, but softened above into the ground colour of the 

 back ; midway between it and the spiracles a fine 

 thread-like line of dull yellowish runs along the sides ; 

 the spiracles are black, each within a blackish-olive 

 blotch ; the tubercular dots are small and black, those 

 on the back have a ring of paler olive at their base ; 

 the dark olive of the subdorsal on one side unites with 

 that of the other side transversely on the twelfth seg- 

 ment, forming there an abrupt termination of the dark 

 colour. The head is reddish and a little shining,
