 and their length is equal to about one sixth the width of the body. The 

 anal filaments or tails are about as wide and twice as long as the lateral 

 filaments. 



Food Plant — So far as the records show this insect feeds only upon 

 the coast sequoia or redwood {Sequoia sempervirens) .

 ford University campus, Palo Alto, Cal., at Woodside, Cal., and in the 

 Sierra Morena Mountains.

 coccus solani, on the lower branches of Malva

 Aster sp., Malva rotundifolia, nightshcide (Solanu^n douglasii), pigweed 

 {Amaranthus retroflexus) , potato [Solanum tuherosum), purslane
