Front, vertex, most of occiput, and entire mesonotum pale orange 

 yellow; face, cheeks, sides of occiput, collar of pronotum, tegulae, 

 almost the entire underparts, the metanotum, propodeum and abdo- 

 men paler yellow, with the center of the dorsum of abdomen brownish, 

 a brown spot on each side of metapostnotum and propodeum partly 

 on each, and the usual broMoi dots on collar of pronotum and tegulae 

 nearly obsolete; concealed part of pronotum blackish.. Antennal 

 scape black with the base and apex rather broadly and a narrow line 

 on upper margin yellowish white; base of pedicel, first two funicle 

 joints and a part of the tliird and club black; apical two-thirds of 

 pedicel, last three funicle joints and apex of the third yellowish 

 white. Legs yellowish with last joint of the tarsi and two narrow, 

 interrupted annuli on all the tibiae blackish. Wings inconspicuously 

 dusky on base and apex, with a transverse band at end of stigmal 

 vein more transparent, entirely due to character of ciliation; the 

 veins pale brownish. 



Male. — Front and vertex about one-half longer again than wide; 

 oceUi nearly in an equilateral triangle, the posterior pair fully their 

 own diameter from the eye margin. Aiitennal scape narrower than 

 in the female, about one-third as wide as long; pedicel and funicle 

 about the same except that the fifth joint of funicle is relatively 

 shorter and wider; club more oval and bluntly rounded at apex, no 

 wider than the preceding joint and as long as the last three joints 

 combined. Length, 1.5 mm. 



Coloration similar to that of female, but the mesonotum more 

 dusky orange especially along the sutures and the sides of the scutum 

 paler; center of occiput, the metanotum, propodeum and entire 

 dorsum of abdomen nearly pure black; dots on corners of the pronotal 

 collar distinct and blackish. Antennae orange yellow with the lower 

 half of scape except at base and apex, the base of pedicel and club 

 black, and the first funicle joint shghtly dusky. Dusky and trans- 

 parent bands of wings less distinct.

 types a to f) reared from Lecanium cerasifex on elm, Columbus, 

 Kansas, May 11-18, 1908 (W. J. Moore), and one female (paratype g)
