48 INSECTS INJURIOUS TO GABDEN AND ORCHARD CROPS. 



The distribution of this plant-bug comprises the entire Gulf region, 

 where it is very abundant, and includes most of the neighboring States 

 if we may judge by its recorded distribution in Arizona, Missouri. 

 South Carolina, and Indian Territory. 



REMEDIES. 



Both of these plant-bugs can be controlled by hand-picking or by 

 capturing them in inverted umbrellas, bags, or specially prepared nets 

 saturated with kerosene, the best time for their capture being in the 

 early morning or late in the evening, as they are apt to be active, taking 

 wing readily, in the heat of the day. 



A certain measure of relief should be obtained by the free use of 

 kerosene emulsion, which will at least kill the younger nymphs. 



The Southern or banded leaf- footed plant-bug could be captured by 

 the use of thistles planted about the infested gardens, fields or orchards, 

 as these plants would attract the insects where they could be more 

 readily dealt with than if scattered. The thistles should be cut down 

 before the seeds mature, and the heads at least should be destroyed by 

 burning, as a single large patch of thistles has been known to infect a 

 wide area. It is possible that immunity from attack might be secured 

 by the destruction of all the thistles within a large area in the neigh- 

 borhood of groves of oranges or gardens, and that no further measures 

 would be needful for the suppression of the pest than constant watch- 

 fulness that no thistles be allowed to grow in the vicinity.

THE EGG- AND OVIPOSITION. 



In Circular 2s"o. 31, on our common striped cucumber beetle, attention 

 was called to the absence of any published observations on the egg and 

 oviposition. Of the normal method of the latter nothing has 

 been positively learned, but egg^ were obtained from which 

 the following description and accompanying illustration were

 Repi. St. Ent. Ills, for 1882, p. 18). There appear to be by estimate 

 about 35 pits in the entire length of the egg.
