equal in size to posterior upper pair. Antennae yellowish, ten-jointed. 
First joint short, cylindrical, second a little longer but thick and oval, 
third a little shorter and slender, enlarged toward tip. Fourth, fifth, 
sixth and seventh subequal, slender, each about twice as long as third; 
eighth, ninth and tenth subequal, the three being not quite as long as 
sixth and seventh together; eighth and ninth distinctly swelled, tenth 
slightly. Three long knobbed hairs at end of tenth joint, All joints 
except first and second with numerous curved hairs. Legs yellow, 
with a slightly brownish tinge, quite hairy. Style, lemon yellow, tap- 
ering sharply at tip. Wings hyaline, with a microscopic pubescence, 
heavier at veins. Veins yellowish. 
Male Puparium—tLength, 1.7 mm.; width, .7 mm. Glassy white 
surface, rounded. Two lines, beginning at the anal opening diverge 
upward for a short distance and then proceed with only a slight di- 
vergence to near the anterior end, when they diverge outward again. 
Surface of the coronet slightly more convex. A quarter of the dis- 
tance from the anterior end, where diverging lines begin to run al- 
most parallel, is a cross carina; another carina crosses the coronet at 
a little more than a quarter of the distance from posterior end. Just 
back of this carina are two spiracular channels, from coronet to each 
margin. Half way between the two cross carinae are the other two 
spiracular channels, running from coronet to margin. There is a 
triangular space for the anal operculum and a cleft from this to the 
margin. 
Egg.—Length, .21 to .24 mm.; width, .12 to .15 mm. Color, lemon 
yellow; oval shaped. When first deposited, light yellow, changing to 
a slightly darker tinge before hatching. Eyes show up as minute 
black spots. 
Larva.—Length, .25 to .3 mm.; width, .15 to .19 mm.; length of 
spines, .1 to .12 mm. Antennae, .07 mm. Color, light yellow, eyes 
minute black spots, body flat and oval, slightly broader and more 
rounded at anterior end. Anal spines slightly less than half the 
length of the body. Antennae six-jointed. Eggs and larva are more 
yellowish than C. hesperidum. 
Habitat, as far as known, on the leaves and twigs of citrus 
trees only. The young scales settle mostly on the leaves and 
when about half grown migrate to the small twigs. No scales 
have been found on twigs larger than one half inch in diam- 
eter. When the insects are abundant, and such is usually the 
case, they are arranged on the twigs in a curiously imbricated 
manner which is quite characteristic. The infestations are 
largely confined to the lower half of the tree.
