with smoky-grey. Mr. Farren, F.E.S., of Cambridge, told me tliat 

 Stainton's description was probably drawn up from a faded specimen, 

 and that his specimens were more purplish-grey, and this is certainly 

 the case ; some are much darker than others. 



Tlie larvas observed at Kingston were all full grown the first 

 week in September, but many matured in the end of August. The 

 caterpillar is chestnut-red, the sides yellowish ; others are deep red 

 all over. The head is dark brown and shiny ; the first segment 

 yellowish-brown ; segments eight, nine, eleven and thirteen have 

 each two lateral spots of a dark hue, and the twelfth has a dark mark 

 in the centre of the dorsum. There are three hairs on the side of each 

 segment, except the last, which has many. Each segment is much 

 wrinkled. The true legs are pale brown ; the prolegs pale pinkish.

 FIG. 239.— LARVA OF THE PLUM FRUIT MOTH (Opadia funebranci). 

 A, I'Hrther enlarged antenna. 



The antennre are of four segments, a bristle arises from the basal one, 

 and another from the base of the fourth, and there are two small ones 

 terminally. When full grown tlie larvte measure about f inch. 



The larv;e, when they leave the fruit, seek shelter under rough 

 bark, debris on the ground, or as was recorded from Headley, under 

 the shreds used for nailing wall trees. 



In such-like places they spin cocoons of whitish silk, and remain 

 as larvte all the winter, giving rise to amber-coloured pupa^ which 

 are dark brown towards the posterior extremity. Kollar (4) also 

 refers to them as pupating under the bark. 



Prevention. 

 Little or nothing has been done to deal with this pest, yet it is 

 one the plum grower has now and then to contend with. At present
