white and conspicuous; present also on the front and vertex but 

 weaker. Antennae pale yellowish brown, the club still paler or 

 yellowish. Coxae and femora of legs yellowish white, the front 

 femora dusky along the lower margin; anterior and middle tibiae 

 more yellowish, especially at apex, the middle pair dusky on the 

 outer surface; posterior tibiae dilute brownish black, fading to yel- 

 lowish at apex; all tarsi yellowish, with the last joint blackish. 

 Wings with two conspicuous blackish cross bands, one with its center 

 beneath the marginal vein, the other on apical half of disk, separated 

 by a whitish band, of which the basal margin is concave and the 

 apical margin straight; basal third of wing and extreme apex also 

 whitish; the blackish bands due in part to integumentary pigment 

 and in part to the ciliation. Exserted part of the ovipositor yellow, 

 but becoming blackish at the apex. 



Male. Similar to the female, but differs in the following par- 

 ticulars: Front and vertex broader than in the female, hardly over 

 twice longer than wide; the ocelli in a less acute-angled triangle. 

 Antennal scape slightly flattened, and a little shorter than in the 

 female, the funicle and club slenderer. Wings uniformly ciliated. 

 Length, 0.9 to 1.0 mm. 



Vertex more or less blackish around ocelli; the center of the 

 occiput, concealed part of the pronotum, the mesoscutum except the 

 sides, the metanotum, propodeum, metapleura, and abdomen brown- 

 ish black; the vertex otherwise, sides of the mesoscutum, axillae, and 

 scutellum orange yellow, the latter somewhat dusky in the center; 

 the mesopleura dusky orange yellow; the front, face, cheeks, and 

 propleura yellow to yellowish white; collar of pronotum, tegulae, 

 and prepectal plates as in the female. Antennae pale brownish, but 

 the scape, pedicel, and club somewhat paler; legs colored as in the 

 female; wings hyaline. 



Described from a female and male (type and allotype) reared July 

 3, 1914, from a nearly full-grown female of a Phenacoccus sp. on 

 apple tree, Lancaster, New Hampshire (Miss G. G. Timberlake); 

 and one male (paratype) reared April 19 from small overwintering 

 female of the same species collected by the writer on March 31 on 

 the bark of apple tree at the same locality.
