 inches long when full grown, of a dark, sooty color, somewhat 

 hairy, and with a double row of five 

 pairs of blue and six pairs of red tuber- 

 cles down the middle of the back, 

 which distinguish it from all other com- 

 mon caterpillars. The brown-tail moths 

 are pure white, with a brown tuft of 

 hairs at the tip of the abdomen, more 

 prominent in the female. Both sexes 

 are strong flyers and are carried readily

 with brown hairs from the tip of the 

 female's abdomen. They hatch early 

 in August, and after feeding two or 

 three weeks the little caterpillars draw FlG . 323 . The brown . tail moth|
