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 coronifcra 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 



auratilis Newst. 



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. -substriata Newst. 



SPECTES OF IIOWARDIA 

 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>
