56 CLASSIFICATION OF THE ALEYRODID.E. 
Wings hyaline, powdered with white. Both the forewings and 
the hind wings provided with small, irregularly formed, brown 
spots that are sparsely scattered. Costa in the forewing fine, but 
distinct. Radial sector (r) in both wings strongly bent in the middle 
toward the exterior margin. In both wings the cubitus terminates 
in the hind corner of the exterior margin. Cubitus in the forewing 
is strongly sinuate at its base, but near its end it is only slightly 
undulated and sinuate. "Analis " in the forewing fine, but can be 
followed distinctly as far as its bouchare in the middle of the pos- 
terior margin, not present in the hind wing. Media and cubitus 
in both wings not quite reaching the margin of the wings, and the 
radial sector terminating quite a distance from the margin of the 
wings. 
Length of the body, male 2.5 mm., female 2 mm.; length of 
abdomen, male 1.75 mm., female 1 mm.; length of forewings, male 
2.5 mm., female 3 mm.; length of hind wings, male 2.1 mm., female 
2.75 mm.; greatest expanse of forewings, male 1.5 mm., female 
2 mm. ; greatest expanse of hind wings, male 1.15 mm., female 
1.5 mm.

Coconut leaves infested with this insect were received August 22, 
1011, from Mr. G. E. Xesom, director of agriculture, Manila, P. I., 
with the statement: 
This scale is ofteu found upon the stems of young fruit and in some cases; 
due to their presence, the tree is unable to set fruit. According to the natives, 
trees infested with this insect often die. Many of the owners of coconut groves 
in the vicinity where this scale is prevalent are rather frightened, and seem 
to believe that if something is not done to check this insect their groves will 
be completely destroyed. 
From the above it would appear that this insect is an important 
enemy of the coconut, exceeding, perhaps, in destructiveness its 
congener cocois, long known from the West Indies.
