THE COCCIDAE 



at proximal end; second pair of lobes elongate, incised, lobe- 

 lets spatulate, mesal lobelet larger than lateral; plates long,, 

 particularly those of lateres, arranged 0, 1, 11, those of each 

 lateris arranged 1-2-2-6; altaceratubae about seven, their ora- 

 ceratubae located in latadentes, those of second and third in- 

 cisura elongate, bluntly pointed, none of the oraceratubae 

 adjacent; each lateris with three pairs of adjacent, short, 

 broad, serrate latadentes; rows of oraceratubae of brevacera- 

 tubae interrupted on meson and divided into mesal and lateral 

 groups; mesospiracerores forming large cluster. Ceylon on 



Fagraea. fagraeae Green. 



cc. Pygidium with genacerores 14-17(28-37)26-56; median pair of 

 lobes narrowed at proximal end, expanded at disto-lateral 

 angles and broadly rounded; second pair of lobes incised, 

 lateral lobelet conspicuous, distinctly rounded at distal end, 

 similar in shape to mesal lobelet; brevaceratubae in two rows; 

 mesospiracerores 19-20, metaspiracerores wanting; plates ar- 

 ranged 0, 1, 11, those of each lateris arranged 1-2-5-3; latadentes 



distinct. Ceylon on Myristica myristicae Ruth. 



aa. Body pentagonal in outline, never oval or trigonal, cephalic margin 

 consisting of three subequal portions, mesal transverse portion and 

 on each side an oblique portion which joins straight lateral thorac- 

 ic margin at an angle; pygidium with median pair of lobes oblique, 

 not or slightly projecting beyond pygidial incision, lateral margins 

 not free, mesal margin slightly convex and serrate; second and third 

 pairs of lobes incised, lobelets bluntly rounded, mesal lobelet slightly 

 longer than lateral; plates of incisurae short, longer than lobes, 

 distinctly shorter than long plates of lateres, arranged 0, 1, 1, 5, 

 those of each lateris arranged 1-1-1- (1-1) ; latadentes in second and 

 third incisurae nearly as large as lateral lobelets; genacerores in 

 five groups. Java on Ilex penzigi Leon. 



SPECIES OF EPIDIASPIS 



Pygidium with median pair of lobes large, broad, rounded, faint lateral 

 notch; second, third, and fourth pairs of lobes small, rudimentary, 

 incised, mesal lobelet largest, all probably latadentes; dorsal setae 

 cephalad of second pair of lobes surrounded by densaria-like thicken- 

 ings; brevaceratubae few in number, elongate, irregularly arranged; 

 plates short, broad, arranged 0, 0, 1, 1, 6, those of each lateris ar- 

 ranged 1-1-1-2-1; anus eight times its width from caudal margin and 

 once caudad of vulva; genacerores (12-16)9-10. Diaspis leperii Sign., 

 Epidiaspis piricola Del Guer. Italy, France, Portugal, Germany, Eng-

 SPECIES OF COCKERELLASPIS 



Pygidium with median pair of lobes distant, rounded, very low, not 

 oblique or divergent, height above margin less than half their breadth; 

 second and third pairs of lobes small, rounded, nearly obsolete; plates 

 small, spine-like, arranged 0, 0, 1, 7, those of each lateris arranged 

 l-(l-l)-l-3; anus longer than broad, located sixteen times its width
