frontovertex; the axillae and scutellum smoother, the latter being consid- 
erably polished at apex; propleura, prepectal plates, and metapleura very 
finely sealy-reticulate, but nevertheless smoothish and shining; the reticu- 
lations on the metapleura much Jess apparent; mesopleura smooth and 
polished; abdomen comparatively coarsely, transversely reticulate, espe- 
cially on the basal tergite, with the reticulations formed by fine raised 
lines, each reticulation generally over twice as wide as long. 
Lower part of face, the cheeks, frontovertex, eyes, and mesonotum 
rather densely covered with fine, short, dark-colored setae, which are reclin- 
ate on the notum, erect and somewhat shorter on the eyes, suberect on 
the frontovertex, and inclined forward on the face and cheeks; scutellum 
with a pair of fine and considerably longer setae on each side of apex; 
pubescence of abdomen rather sparse and longer than that of the thorax, 
but not in any way- conspicuous or distinctive. 
General color dark metallic green, the face brilliant green, with the 
upper part of the antennal prominence above the socket dark purple; 
mesopleura also somewhat purplish; abdomen nearly black with a purplish 
and greenish luster; antennae black; legs metallic blackish with trochan- 
ters, base of all the femora, knee joints, tip of hind tibiae, apical third 
of front and middle tibiae and all the tarsi except apical joint brownish 
yellow, this color of the middle tibiae and tarsi being somewhat paler, and 
the hind tarsi dusky above; mandibles brown; the palpi yellowish white; 
wings hyaline, with dusky yellowish veins. 
Length of body, (0.655 to) 1.07; length of head, 0.884; width of head, 
0.419; thickness of head fronto-occipitally, 0.252; width of vertex at 
anterior ocellus, 0.209; length of antenna, 0.659; width of mesoscutum, 
0.421; length of fore-wing, 0.912; width of fore-wing, 0.426 mm. 
Described from 153 females, 59 males (holotype, allotype 
male, and paratypes) reared from Pseudococcus calceolariae 
(Maskell) on sugar-cane collected at El Potrero, Vera Cruz, 
Mexico, in May, June, and July, 1922, by H. T. Osborn, and 
in part bred in Honolulu from the same host and also from 
Pseudococcus sacchari (Cockerell) and Pseudococcus kraunhiae 
(Kuwana).
