'9*3- The Amer i ca n Fl o r /st. 213 soaked In a solution, or the plants dusted with the poison In a powdered form before planting. The scale In- sects which attack the roots of Opuntla plants do n"i have a marked affect on their vigor, i 'i i he coreld bug, which attacks the joints externally, the bulletin furnishes the following description: "it is a yellowish bug, resembling the com- mon squash bug In general appearance, feeding generally gregariously on the Joints of Opuntla and allied genera. It Is chiefly nocturnal in its ; These i. by far the most harmful Insects feeding "ii the plants. The bug leaves i small circular discoloration on the joints of the plant which are nol dis- covered for some time after the feed- ing begins, li becomes very conspicu- ous soon, however, and the plant be- COmeS weakened and falls over. The scientific name of this img is Chelini- dea vittigera, and with it is sometimes found the Chelinidea tabulata West- wood. This latter insect is not com- mon, the only thing which keeps it from being a serious menace. The bulletin recommends the burn- ing of the trash upon which the insects collect in winter when they are nearly dormant. The gasoline torch may be used effectively to get rid of the im- mature insects, at which stage they are of a very gregarious habit. Next in importance to these Chelinidea bugs is the Mimorista flavidissimalis. Its range is limited, however, being con- fined to parts of Texas and Arizona. The cottony cochineal insect, closely allied to the true cochineal insect, which is not found in the United States, are frequently found in large masses in the joints of Opuntia. The true cochineal insect has long been well known as the source of a dye taken from the dried bodies of the female. The larvae of the insects which feed on the inside of the joint are laid on the outside and the insects work their way inside
