" This bug is a very variable species, the males being 

 generally much darker than the females. The more com- 

 mon color of the dried cabinet specimens is a dirty yellow, 

 variegated * * * with black and dark brown ; and one 

 of the most characteristic marks is a yellow V, sometimes 

 looking more like a Y, or indicated by three simple dots on 

 the scutel, (the little triangular piece on the middle of the 

 back, behind the thorax.) The color of the living specimens 

 * * * frequently inclines to olive- green. The thorax, 

 which is finely punctured, is always finely bordered and 

 divided down the middle with yellow lines, very frequently 

 obsolete behind. The thighs always have two dark bands or 

 rings near their tips." — (Riley.) 



Remedies. Pyrethrum is effective against this insect, 

 as is also the kerosene emulsion, provided it contains not less 

 than five per cent, of the kerosene.
