(8). Phenacoccus comari (Kunow). Coccus comari Kunow, Ent. 
1880. Near Königsberg. See also Douglas,

(4). Dactylopius edgeworthix, n. sp—? about or hardly 2 mm. 
long, pale gray, with light brown legs and antenne. 
Form oval, back so thickly dusted with white meal as 
to appear white with a grayish tint; no distinct lateral 
or caudal appendages; extremely short, hardly notice- 
able thick caudal tufts. The white secretion on the . 
back forms three more or less distinct longitudinal rows 
of small protuberances, giving the insect an obscurely 
tricarinate appearance. Immature ¢ similar, but not 
so mealy. 
ọ boiled in KHO turns very dark lake-red, but does 
not stain the liquid. Antenne 7-jointed, formula 7 
(82) (41) 65. 3 is perhaps a little longer than 2; 7 is 
considerably longer than 5+6 ; 5 is very little shorter 
than 6; 4 is conspicuously shorter than 2 or 3. Legs 
ordinary, femur quite stout, its upper edge convex ; 
tibia a little shorter than femur, stout; tarsus a little 
shorter than tibia. Claw moderate, with a minute den- 
ticle on its inner side. Digitules of claw slender, some- 
what curved, extending a little beyond tip of claw, with 
fairly distinct knobs; no tarsal digitules. Anal ring 
with the usual six bristles. Caudal tubercles very low, 
ordinary, each with a large bristle, some short ones, 
round glands and a pair of conical spines. The insect 
throughout is very little hairy. The skin exhibits 
numerous gland-dots. 
3 sac ordinary; a 3 with wings expanded taken 
from a sac. Length of body about 1% mm.; head to tip 
of wing about 2mm. Wings white, the nervures very 
distinct, costa not at all darkened. Antenne pale och- 
reous, head pale olivaceous, prothorax dark slate gray,
