ally spray tbe trees. He therefore picked the fruit as the only remedy. 

 The same difliculty— that the bugs are continually flying to the 

 groves — will operate against any remedy which may be tried at this 

 time. The only remedy previously published we may quote from Mr. 

 Hubbard : 



As was long ago suggested by Mr. Glower, in his report above mentioned, the bugs 

 may be attracted to small heaps of sugar-cane trash with which Paris green or some 

 other poison should be mixed ; or the bugs, when collected upon piles of cotton-seed 

 in winter, may be destroyed by drenching them with boiling hot water. The expe- 

 rience of several cotton planters with this last method has shown it to be practica- 

 ble, but to be effective it must be thoroughly carried out. As the eggs can not all be 

 reached and destroyed by hot water, the operation needs to be repeated several times 

 at such frequent intervals that the bugs are not allowed to reach maturity and deposit 

 fresh eggs. 



In the orange grove effective traps may be made with refuse oranges, orange peel, 

 etc., and the bugs, when thus collected, maj^ be destroyed with the kerosene washes 

 used for Scale insects. The kerosene solutions will also be more etfective than hot 

 Avater in reaching and killing the eggs. 



As Mr. Hubbard further states, the cultivation of cotton through the 

 orange-growing district of Florida is for many other reasons likely to 

 diminish rather than to increase, and with the abandonment of this 

 cultivation we may expect the Eed Bug to do less and less damage to 

 oranges, if not to disappear entirely as an orange pest, unless (and this 

 is not over likely to happen) it should breed extensively upon some 

 wild plant. 



CAN THE RED BUG BE USED AS A DYE? 



In the old days of expensive dye substances it was thought from the 

 brilliant red color of these bugs that they could be used for some such 

 purpose. Accordingly Dr. Charles T. Jackson, of Boston, was sent a 

 number of these bugs in 1858 from this Department (then a bureau of 

 the Patent Ofiice), and from his report, published in the Annual Report 

 for that year, it api^ears that the whole substance of the insect could 

 be converted into a rich orange-yellow dye which could be readily fixed 

 upon woolens or silks by the alum-mordant liquor. He also found that 

 an ochreous yellow-lake could be made from them by precipitating the 

 coloring matter with gelatinous alumina. 



A PARASITE OF THE SUPPOSED EGGS OF THE COTTON STAINER. 



By L. O. Howard. 



In the article just preceding this parasite is mentioned and at Fig. 50 

 is shown one of the eggs which was so transparent that the contained 

 parasite could be quite plainly seen. Carefully removing the egg-shell 

 the parasites were found to be adults and in such i)erfect condition — 

 evidently just ready to issue — that the following description was drawn
