A. cyanophyUi Sign., Ann. Soc. Ent. Fr., (4), ix, p. 119 (1869). 



Scale of female: Circular, brownish-yellow; exuviae central, 

 bright yellow, covered by white secretion. 



Scale of male: Similar to scale of female, elliptical in outline, 

 exuvia sub-central. 



Female: Median lobes very large, as broad as long, notched on 

 each side near apex, appearing to project into the segment; second 

 lobes long, narrow, about one-third the width of the median lobes, 

 slightly notched on each side near apex; third lobe similar but smaller. 

 Plates long, extending beyond lobes, deeply incised; two between 

 median and second, three between second and third lobes, and outside 

 of third lobe five or more simple bi-furcate or tri-furcate plates. 

 Spines long and slender, not exceeding the plates in length; on the 

 dorsal surface there is a spine on each lobe and one two-thirds of 

 distance to penultimate segment; on the ventral surface a spine lat- 

 erad of each corresponding dorsal spine except on the median lobe. 

 A few smaller spines scattered over surface of segment. Four groups 

 of cireumgenital gland-orifices; anterior lateral, 4-5; posterior lateral, 

 3-5. Anal orifice large, remote from margin of segment. 



Remarks: On leaves of palm, Pritcliardia fiUfera, in Ohio 

 State University Conservatory. Originally described by Signoret 

 at Paris from Cyanophyllum magnificum.

Being unable to procure specimens of this species, the following 

 description, and the illustration are taken from the above bulletin: 



Scale of female: "Circular, 2 mm. in diam., convex, dull-reddish- 

 gray; exuviae sublateral, inconspicuous with exception of the first 

 skin which shows as a yellow prominence." 



Female: "Female anal segment with median lobes long and close 

 together, each lobe notched on both inner and outer margins, outside 

 margin of lobe straight below notch; rudiment of second lobe wide, 

 often notched; rudiment of third lobe slightly raised at inner angle. 

 Median incisions narrow, edges straight; second and third incisions 

 small. A small chitinous process at outer base of median lobe; a broad 

 chitinous band surrounding each second and third incisions, either 

 band sometimes, but rarely, divided at apex of incision so as to appear
