INSECTS INFESTING THE APPLE TREE. 109 



lines. The wings, which are only two in number, are trans- 

 parent, and marked with four black cross bands, which are 

 more or less united with each other. The only remedy seems 

 to be to gather the infested apples before the maggots have 

 deserted them, and make such use of them as will destroy the 

 maggots. This insect, so far as is reliably known, has not yet 

 been found in California, but from descriptions given of the 

 decay of late varieties of apples in 1882, it is thought neces- 

 sary to give the above description. (See U. S. Agr. Rep. for 

 1881.) 



Remedies. — Should this insect appear, it can be kept oif the 

 fruit by spraying, in July and August, with Nos. 5 or 7, but 

 probably No. 4 would be better. 



CHAPTER LIII. 



The Apple Cureulio. (Cal.) 



(Anthonomus quadrigibbus — Say. ) 



Order, Coleoptera ; Family, Curculionid^. 



[The measurements of insects in this work are given in inches and lines. The above cut rep- 

 resents one inch divided into lines and fractions thereof.] 



[Living in apples, pears, and quinces ; a curved, footless 

 grub of a white color, marked with bluish-black ; assuming 

 the pupa form within the fruit, and finally producing a rusty- 

 brown snout-beetle, having three pale lines on the thorax, and 

 four humps on the wing-cases.] 



The female cureulio punctures the apple with her long snout, 

 and after widening the puncture at the bottom, she deposits 

 therein a single egg, from which is hatched a footless grub 

 (Fig. 856) which burrows still deeper into the fruit, and feeds 

 upon the latter in the vicinity of the core. After attaining its 

 full growth, it forms a small cell, with a burrow leading from 

 ^it to the outside of the apple, and in this cell it soon casts off 

 'its skin and enters upon the pupa stage (Fig. 85a), from which 

 the perfect beetle is evolved in the course of a few weeks.
