Rostrum: Reaches to the base of the abdomen; dark excepting 

 the basal third which is amber. Thorax: Dark amber with black 

 spots around the spiracles and on the dorsum arranged in trans- 

 verse rows. Abdomen: Dark amber or reddish-brown, with black 

 markings around the spiracles and black spots along the sides. 

 Legs: Average in size, differing in no important respects from 

 those of the wingeci form. Cornicles: Greatly resemble those of 

 the winged form in size and shape as shown in Fig. 2, E. The 

 area arounci the base is more mottled and not uniformly dark as in 

 the winged form. Cauda: Rounded, hairy, dusky around the 

 margins. 



Young 



The immature forms vary from very light yellowish or amber to 

 dark amber and may or may not be covered with the whitish 

 powder. 



Food Plant 



This species feeds upon the bark of the small twigs of the Jap- 

 anese dwarf silver spruce, Picea glehni Mast. The insects are often 

 so abundant as to entirely cover the small branches. 



Locality 

 This species has only been taken from two trees growing together 

 in the Capitol Park, Sacramento, Cal., near the east entrance of the 

 Capitol Building. The trees are said to have been imported from 

 Japan and it is possible that the insect in question was imported 

 with them.
