Aspidiotus cydonia Comstock. 



Aspidiotus cydonim Comstock, Fernald, Cat. Coccidae of the World 

 (1903), 256. 



Female scale circular, 1.5 millimeters in diameter, convex, 

 gray; exuviae subcentral, marked by a brown spot. Adult fe- 

 male circular; median lobes of caudal margin with a notch on 

 each side, second and third lobes represented by thickenings of 

 the body wall or slight projections; simple plates between me- 

 dian lobes, five fringed plates laterad of these lobes ; short spines 

 laterad of the lobes and thickenings (Plate V, fig. 1). Circum- 

 genital glands with anterior laterals of 8 or 9 orifices, posterior 

 laterals of 5 to 7.

Very similar to Aspidiotus cydonise. in characters of the female 

 and color of female scale, but the exuvise differ; however, the 

 exuviae are similar to those of A. latanise. The three are so 

 much alike that they may be no more than varieties.

Aspidiotus latanise Signoret, Fernald, Cat. Coccidae of the World 

 (1903), 266; Cockerell, Proc. Davenport Acad. Sci. (1905), 10, 133. 



Female scale circular, 2 millimeters in diameter, flat; exuviae 

 cream white, densely coated, but a yellow spot in the center of 

 each scale. Median lobes of caudal margin large and prominent, 

 notched on each side, notch on inner side often imperceptible; 

 two deep incisions on each side with conspicuous, thickened 

 chitinous rim; laterad of each thickening a pointed glandular 

 process; two spines between the median lobes, fringed spines 

 laterad of median lobes. Circumgenital glands with anterior 

 laterals of 3 orifices, posterior laterals of 6 or 7 orifices. In 

 every respect the characters of the caudal margin agree with 

 those of A. cydonise. (From Green and from the original de- 

 scription of Signoret.)
