56 CLASSIFICATION OF THE ALEYRODID^. 



Wings hyaline, powdered with white. Both tlie forewings and 

 the hind wings provided with small, irregularly formed, broAvn 

 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 forev/ing 

 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

Coconut leaves infested with this insect were received August 22, 

 1911, from Mr. G. E. Nesom, director of agriculture, Manila, P. L, 

 with the statement: 



This scale is often found upon the stems of young fruit and in some cases, 

 due to their presence, the tree is luiable 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.
