INSECTS INFESTING THE APRICOT.

ference between this species and the striped cucumber beetle 

 can be readily distinguished. The larva probably lives in the 

 roots of some kinds of plant. 



Remedies. — Spray trees infested by this beetle with No. 5, 

 or 7, or 65. If the trees are seriously infested, by stirring or 

 mixing one pound of buhach in fifteen gallons of the mixture, 

 it will effectually destroy the beetle. When gathered in large 

 numbers in one place, as described above, the solution, mixed 

 with buhach, should be used.

[Feeding upon the l)uds and leaves of v^arious kinds of 

 plants, and also upon ripe or nearly ripe fruit ; a yellow beetle 

 (Fig. 112^) about three lines long, the head black, and the 

 wing-cases marked with twelve black spots.] 



The early stages of this beetle have never been 

 traced out, but it probably lives in the ground 

 in the larva state, feeding upon the roots of 

 plants.

 Remedies. — The fruit in an orchard in this vicinity (Sacra- 

 mento) was attacked by these pests in the month of August, 

 1883. The owner sprayed the trees with a solution composed 

 of six pounds of buhach steeped in one gallon of alcohol, then 

 diluted with twenty gallons of water; this destroyed the pests 

 very etlectually. I have succeeded in driving them off' of the 

 trees by spraying the latter with Remedy No. 5 or 7, one pound 

 to each gallon of water used. 



Note. — Since writing the aitiole on the Horned Flower-beetle (page 259), I learn that these 

 beetles sometimes burrow into ripe peaches, pears, and plums ; and they are alf-o charged with 

 gnawing off the green grapes and letting them fall upon the g'round.
