The Gloomy Scale 
17 
shape of the body is broadly triangular, with the head narrow. The 
antennae, legs, and wings are developed as sack-like outgrowths of the 
body. 
The pupa is pale chitin yellow in color, with the legs, wing pads, 
antennae, and style well developed (Tig. 10). The antennae reach to 
almost the base of the abdomen. The forelegs are folded forward, with 
the tips of the tarsi reaching the base of the antennae. The femora of 
the middle legs project later ad and the tarsi are bent toward the end of 
the abdomen. The hind femora project backwards, with the tarsi bent 
at almost right angles. The style is short, measuring about .10 mm. 
in length.

The adult male is a strong chitin yellow in color, with head and 
eyes darker (Tig. 11) ; the wing expanse is about 1.60 mm.; length of 
body, including the style, .75 mm.; style long and slender, about .24 mm. 
long; the antennae are as long as the body, ten-jointed; basal joint short, 
scarcely half as long as second; second, third, and fourth sub-equal, 
which are one-half longer than fifth and sixth; seventh and eighth half 
as long as fifth; ninth as long as seventh and eighth together, broader; 
tenth about three-fourths as long as ninth, gradually tapering to a fine 
point. The antennae are covered with short, sparse hairs. The head is 
small, with the lateral eyes situated just laterad to the antennae; the 
diameter of the ventral eyes is about twice that of the lateral eyes. The 
prothorax is crescent shaped, about one-tliird as long on the middle as 
the mesothorax. The thoracic band is brownish in color and rather 
broad. The metatliorax is about one and a half times as long as meso¬ 
thorax and considerably inflated. The abdomen is flat and expanded. 
The scale of the male (Tig. 12) is broadly oval in outline, of the 
same color as the female scale, and measures about .910 mm. in length 
and about .0680 mm. in breadth at the broadest part. The larval skin is 
near the anterior end. The ventral scale is white, with the margins 
darker and somewhat thicker.
