and last three funicle joints pale yellow. Legs yellowish white, 

 with a pale brown spot on upper side of the femora near apex, and 

 with two blackish brown annuli on all tibiae, sometimes interrupted; 

 tarsi pale brownish yellow, the last joint hardly darker. Wings with 

 contrasting bands of dark and whitish cilia as described above; 

 veins pale brownish. 



Male. Front and vertex a little less than twice as long as wide; 

 ocelli arranged as in the female. Antennal scape a little narrower 

 than in the female, widest across the middle; pedicel shorter and 

 wider, about as long as the first two and one-half of the third funicle 

 joint combined; first funicle joint rounded, a trifle wider than long, 

 following joints distinctly wider than long and increasing in width, 

 the first four subequal in length, the last two somewhat longer; club 

 usually not wider than preceding joint, widest across the base and 

 tapering to bluntly rounded apex, as long as the last four funicle 

 joints combined. Wings as in the female. Length: 0.7 to 0.9 mm. 



Coloration very nearly as in the female, but the dark markings 

 of abdomen more extensive and sometimes nearly pure black, with 

 the transverse, basal white band reduced to a spot on each side of 

 dorsum, and the submarginal lateral streaks present but shorter 

 and yellowish in color. The black on antennal scape somewhat 

 more extensive, and the first three funicle joints and club more 

 brownish. 



Redescribed from thirteen females, ten males (cotypes) reared from 

 Lecanium on pine (probably PJiysoJcermes insignicola Craw) and Le- 

 canium on Heteromeles and Quercus agrifolia, two males from Los 

 Angeles County, California, remainder- of specimens 1 from Ala- 

 meda County, California (A. Koebele), Koebele's Nos. 193, 215, and 

 406; also a large series of both sexes reared from PJiysolcermes 

 insignicola (Craw), Santa Maria, California, August 4-24, 1911 (R. C. 

 Wylie), from Lecanium pub escens Ehrhornand Lecanium corni Bouche", 

 Berkeley, California, March 30 to May 5, 1911 and 1912 (H. J. Quayle, 

 P. H. Timberlake). 



The male described by Dr. Howard is a much different insect and 

 appears to be a new species of Blastothrix.
