less wrinkled appearance; without spines, rods, or any form of 

 wax secretions; margin finely crenulate, without wax fringe. 

 Vasiform orifice subtriangular, with angles rounded, about four- 

 fifths as broad as long; operculum semicircular, slightly broader 

 than long and reaching nearly half the length of the orifice; 

 lingula rather coarsely papillose for nearly its entire length, 

 irregularly seven-lobed, the terminal lobe projecting between two 

 spines or setae which are about 16/x long. 



Adult female about .86mm. long; fore wing about 1.34 x 

 .54mm., white, immaculate; body, legs, head and antennae, pale 

 yellow ; eyes strongly constricted but not divided. Entire surface 

 of body and wings covered with a mealy secretion of wax. Male

Pupa case, about .80 x .46 mm., broadly elliptical greenish 

 yellow, the margin finely crenulate; dorsum nearly flat, rugose; 

 segmentation fairly distinct ; no lateral wax rods and no wax rods 

 on disk of dorsum ; two submarginal rows of wax rods, the outer 

 radiating, variable in length, but never exceeding three-fourths 

 the breadth of the dorsum ; the inner series of rods are also vari- 

 able in length, rarely exceeding the breadth of the dorsum, and are 

 curved upward over it. Vasiform orifice subtriangular, corners 

 rounded, longer than broad, bounded laterally by chitinous ridges. 

 Operculum has the form of half an ellipse (cut through the short- 

 est axis) reaching a trifle more than half the length of the orifice; 

 lingula with apical lobe between two spines, and three pairs of 

 lateral lobes, densely covered with minute setae in longitudinal 

 rows. A shallow furrow reaches from orifice to caudal margin. 



Adult female about 1.17 mm. long; fore wing about 1. x .5 mm., 

 immaculate, abdomen pale yellow, head, thorax, legs and antennae 

 pale buff, tip of rostrum black, covered with white flour-like or 

 mealy wax secretion. Male like female though smaller. 



This was formerly confused with the following species and 

 occasionally infests strawberries to such an extent as to cause 

 distinct injury.
