A Southern Insect. 



The Harlequin Cabbage-bug is a sontliern in.sect, the first informa- 

 tion of which came from Texas in the year 1866, when it destroyed all 

 the cruciferous plants in a number of gardens. Since that time, it has 

 gradually worked its way northward. Although no complaints have

 ably at the present time, judging from its observed rate of progress, 

 made its appearance in the southern counties of the State. It is there- 

 fore important that our cabbage and turnip culturists should, in ad- 

 vance, inform themselves of the appearance and history of this pest, 

 which is steadily moving toward them, in order that those who hold 

 the advance ground of the invasion may interpose every possible im- 

 pediment in the way of its permanent occupancy and its northward 

 extension. 



During the last two years, several statements have reached me from 

 localities in Virginia and Tennessee, detailing the injuries inflicted by 

 this bug upon cabbages, and asking for remedies against it. A corre- 

 spondent from Ivy Depot, Va., under date of Sept. 24th, writes : *' I
