428 THE COCCIDAE 



cc. Pygidium with cephalic portion abruptly constricted so that 

 subparallel lateral margins of portion caudad of constriction 

 meet cephalic portion at an angle; pectinae and lobes like 

 those of occultus; oraceratubae few in number; pectinae long 

 and deeply lacinate; insects forming cylindrical galls twice 

 as long as wide, constricted at base, ends often studded with 

 irregular tubercles, upon lower surface of leaf. — Aspidiotus 

 (Cryptophyllaspis) occultus elongatus Green. — Ceylon on 



Grewea. elongata Green. 



aa. Pygidium with three pectinae on each lateris. 



b. Pygidium with three deeply lacinate furcapectinae on each lat- 

 eris; median pair of lobes with slight mesal and lateral notches; 

 three pairs of lobes not darkened; pectinae narrow and strongly 

 fringed, each lateris with three double pectinae each having ap- 

 pearance of two squames (plates?) joined at proximal end; in- 

 cisurae with densariae; dorsal oraceratubae not numerous, ar- 

 ranged in two rows on each side; setae small. — Bismarck Archi- 

 pelago on Codiaeum. rubsaamcni Ckll. 



bb. Pygidium with three deeply lacinate unapectinae on each lateris; 

 median pair of lobes elongate, deep mesal and lateral notches, 

 distal margin bluntly pointed; second pair of lobes much smaller, 

 unsymmetrical, oblique, margin with deep lateral notch or cren- 

 ulate; third pair of lobes irregular, pointed, notched; pectinae 

 deeply lacinate, much longer than median pair of lobes, arranged 

 2, 2, 3, 3-5; dorsal oraceratubae distinct; insects forming small 

 conical galls on leaves. — Canary Islands, Maderia on Globularia.__
