Aspidiotus juglans-reg-iae Comst. var. Plate IV, Fig. 17. 



Scale of male, oval, elongate, i mm. in length, raised anteriorly, 

 flattened posteriori}', darker than female, exuvicC situated near 

 anterior margin, covered with white secretion, ring and dot within 

 distinctly seen upon exuviae. 



Scale of female, diameter less than 3 mm., not more than 2)4 

 mm. Ventral scale "mere film," "adheres to bark." Color and 

 position of exuviae agree fairly well. 



Female. Color pale j^ellow with "irregular orange colored 

 spots." Oral setae and last segment dark yellow. Number of 

 circumgenitals do not agree with description, as shown by my 

 drawing. 



Lobes three, three pair present, pointed, plates "simple, incon- 

 spicuous," "resemble spines," the largest found caudad of each 

 incision. Some specimens show simple plate between median 

 lobes. 



Incisions shown in figure. Mesal bases of median lobes slightly 

 chitinized. Spines agree, except that on median lobe I find a spine 

 not shown or mentioned by Comstock 



Spines. First spine on mesal lobe, a pair between first and 

 second incision, a third pair laterad of third lobe. This pair is 

 also about half way between the median lobe and fourth pair of 

 spnies. 



Plates inconspicuous, arranged as shown in drawing, one between 

 median lobes, one cephalad of first incision, two cephalad of second 

 incision, all simple. 



Circuingenital glands, five groups, variable, extremes found are 

 caudo-laterals 2 to 12, cephalo-laterals 8 to 13, anterior o to 5. 

 Chitinized clubs present along side glands as shown. From ten 

 prepared specimens of females and many scales of male and female.
