dusky pale green. Tibia dusky yellow, tips and tarsi black. Last 

 abdominal segment and cauda in some specimens distinctly pale 

 green." 



This species was first found on Cupressus in the Stanford Uni- 

 versity nursery by Childs and Crawford on February 21, 1912, and 

 the above color notes were written by Morrison on this date. Both 

 alate and apterous forms were present. It was taken again at the 

 same place on March 17, 1912, and April 14, 1912. It was again 

 taken by Morrison on May 21, 1915, in Golden Gate Park, San 

 Francisco, alate and apterous adults and apterous nymphs, and by 

 Harold Compere at the same place during the same month. In 

 August, 1916, Swain found the apterous form on terminal leaves in 

 Exposition Park, San Diego.

There is in the national collection a metatype slide, containing two 

 adult alate viviparous females, two alate nymphs, one apterous 

 viviparous female, and one intermediate. This collection was made 

 in Minnesota from Ndbalus alhus on July 11, 1903, by Pergande and 

 determined by Oestlund. All drawings were made from this slide, 

 and the following descriptions are chiefly from this slide, supple- 

 mented by comparisons with certain other specimens. 



Alate viviparous jemale. — Antennae longer than body, dark colored, 

 segments III, IV, and V very tuberculate for their entire lengths; 

 one specimen with only a few on V; hairs conspicuous and heavy 

 with a tendency to be knobbed. Antennal tubercles rather short. 

 Beak reaching second coxae. Radial sector going somewhat closer
