206 TRANSACTIONS OF THE ILLINOIS 



larva produced therefrom works chiefly near the surface of the fruit, and 

 does not penetrate to the heart in the quince. When fully grown its 

 average length is about one-third of an inch, its diameter being rather 

 less than one-fourth its length ; it is straight ; dull white, with a narrow 

 dusky line along the back, which is usually indistinct on the front part ; 

 head reddish brown ; jaws black at the tips, with two teeth at the apex. 



Having completed its larval growth, it leaves the fruit and burrows a 

 few inches into the ground, but instead of changing into a pupa it remains 

 in this state during the winter, and does not assume the pupa form until 

 about the first of May, according to Prof. Riley, a few days before issuing 

 as a beetle. 



This species attacks and breeds in the haw, which is probably its 

 favorite native fruit, also the quince and pear. 



Remedies. — As this species has the habit of dropping when disturbed, 

 the same remedies applicable to the plum-curculio will be equally effectual 

 against it. 



Analeis fragarice, Riley. Strawberry Crown-borer. 



This little curculio, which is about one-sixth of an inch in length, 

 is of a chestnut brown color ; the thorax is somewhat darker, and is covered 

 with large punctures ; the wing-cases are marked with numerous lines of 

 punctures, and are more or less covered with short, pale yellow hairs, which 

 form, by their increased density, three indistinct bands, one at the base, 

 one at the middle, and one near the tip ; between these are darker partial 

 bands, darkest near the outer margin of each wing-case. 



This species is especially injurious to strawberry plants, in which the 

 larva bores and undergoes its transformations. In the latter part of June 

 and first half of July, in Southern Illinois, but somewhat later in the 

 northern part, the female beetle deposits an egg, probably in the crown 

 of the plant. The larva hatched therefrom bores its way downward into 

 the pith. Here it remains until it has acquired its full growth, working 

 into the root, and often eating its woody portions. The result is that 

 the plant is so injured that it is unable to bear the rigors of winter, and 

 dies. 



The larva is a minute, footless grub, but the legs are represented by 

 small tubercles ; it is white, thick and curved ; the head smooth and yellow, 

 with some faint transverse lines above the mouth ; the biting jaws reddish, 

 tipped with black ; a faint narrow line is visible along the back. Length 

 about one-fifth of an inch. 



Prof. Riley, from whose report the above account of this insect is taken, 

 is inclined to think, from all the facts known in reference to its history, 

 that it is single-brooded, and that it passes the winter in the perfect state ; 

 but this has not yet been positively ascertained. 



Re^nedies. — Dr. Hull says the crown-borer goes into the top of the 

 plant, and thence into the crown ; then he is beyond our reach and we 

 have no means of arresting his progress. Mr. Miller, who has had expe-
