Redescribed from two females (cotypes) reared from a Lecanium 

 on Adenostoma fasiculatum, Alameda County, California, June, 1887 

 (A. Koebele), Koebele's No. 252; and two females reared from 

 Lecanium corni Bouche, Santa Rosa, California, June 15, 1908 (E. M. 

 Ehrhorn). The following Eastern specimens hardly differ and must 

 be considered to belong here, at least until the species is better known 

 from larger series: One female, Oakland, Maryland, July 12; and one 

 female reared from Lecanium nigrqfasciatum Pergande, Harrisburg, 

 Pennsylvania, October 22, 1909 (P. R. Myers), Myers' No. 269.
