SPECIES OF CORONASPIS 



a. Pygidium with median pair of lobes rounded, not tricuspid; two 

 or three pairs of minute inconspicuous bluntly lanceolate lobes, 

 median pair simple, second pair incised; plates prominent, ar- 

 ranged 0, 1, 8, those of each lateris arranged 1-1-1-1-4; dorsal ora- 

 ceratubae large, conspicuous, arranged in more or less definite 

 rows; anus broader than long, about eight times its width from 

 caudal margin; body after gestation reddish and densely chitin- 

 ous; antennae consisting of corona-like area bearing four to six 

 stout spines and central curved seta; caudad of each antenna and 

 scattered over thoracic region oval translucent spaces; margin of 

 preabdominal and caudal thoracic segments with numerous ora- 

 ceratubae, obscure in densely chitinous individuals; scale of adult 

 female white, sometimes tinged with ochreous, exuviae reddish, 

 sides of scale sloping up and forming median longitudinal rounded 



ridge. Ceylon on undetermined tree coronifera Green. 



aa. Pygidium with median pair of lobes small, mesal and lateral mar- 

 gins subparallel, distal end tricuspid; second pair of lobes incised, 

 mesal lobelet large, lobe-like, much larger than a median lobe, mar- 

 gin rounded, entire, lateral lobelet tricuspid, similar in form to a 

 median lobe; plates slender, longer than lobes, arranged 0, 1, 2, 

 those of each lateris located one near second lobe and other at 

 cephalic end; altaceratubae 5-6 on each side; lateres serrate be- 

 tween altaceratubae ; antennae adjacent cephalad of head skeleton, 

 each corona-like, margin with long spiny process, two longer than 

 others, and two long setae; mesospiracerores 3, mesoperitreme 

 very large and depressed; scale of adult female elongate, strongly 

 convex, pure glistening white, finely laminate, exuviae orange yellow 

 to orange brown; male scale strongly carinate, secretionary portion 



dull gold color. Uganda, islands of Lake Victoria, Africa

SPECIES OF DENTASPIS 



Scale of adult female satiny-white, transversely striate, striae equidis- 

 tant and distinct, sides subparallel; body with cephalic region nar- 

 rowed; pygidium with median pair of lobes distant, not located in 

 pygidial incision, projecting, distal margin deeply serrate; second 

 pair of lobes distant from median pair twice its width, similar in 

 form, smaller, incised, deeply serrate; third pair of lobes only slight 

 projection on margin, serrate, not incised; plates longer than lobes, 

 arranged 0, 1, 1, 1-2, those of each lateris near third lobe; altacera- 

 tubae with tubes about as long as wide, arranged two cephalad of 

 plate in second incisura, one associated with each second lobe and 

 one near each third lobe. Uganda, Africa on palms. -.subs triata Newst. 



SPECIES OF HOWARDIA 



Scale of adult female broadly oval, caudal end narrowed, often almost 

 circular, exuviae terminal; pygidium with median pair of lobes large, 

 prominent, mesal angle roundly protuberant, lateral margin finely ser- 

 rate, mesal margin substraight, not adjacent; second pair of lobes 

 not incised, small, bluntly pointed, entire; lateres with serrate pro-
