dd. Median pair of lobes uiformly rounded, entire, not notched, 

 scarcely adjacent, mesal margins divergent; second pair of 

 lobes similar to first, entire, not notched; small rounded 

 lobelet caudad of second lobe may be lateral lobelet of sec- 

 ond lobe; plates arranged 0, 1, 3, those of each lateris sit- 

 uated, one near second lobe, one at middle, one at cephalic 

 end; genacerores 6-6(16-17)11-12; mesospiracerores 7-10. —

SPECIES OF HEMIASPIS 

 Pygidium of median pair of lobes adjacent, semicircular in form, mar- 

 gins entire, lateral margin entire or with faint notch; other lobes 

 wanting; plates flattened, caudal one not as long as lobes, arranged 

 0, 1-1-1-1, cephalic plate very broad; minute paraphyses, two pairs, 

 or thickenings located between caudal, first and second, and second 

 and third plates; dorsal octaceratubae few; genacerores 4-4(6-6)4-4. — 

 Lepidosaphes hemichionaspiformis Green. — North Australia on Mela- 

 leuca. hemicMo7iaspiforviis Green. 



SPECIES OF ISCHNASPIS 

 a. Pygidium with two plates in each second incisura; plates arranged 

 0, 2, 6, those of each lateris two, distant, at caudal end, two sub- 

 adjacent one-third from caudal end, and two subadjacent near 

 cephalic end; median pair of lobes broadly rounded, widely sepa- 

 rated, not oblique, finely serrate; second pair of lobes incised, each 

 lobelet similar to median, entire, broadly rounded, mesal lobelet 

 larger than lateral; large oraceratubae in each second incisura 

 laterad of its plates and another laterad of each second lobe; mar- 

 gin of pygidium broadly concave between caudal oraceratubae; 

 genacerores in three groups, median group 3-4 and each lateral 

 group 4-6. — Lepidosaphes ritsema-bosi Leon. — United States, West 

 Indies, Brazil, Great Britain, Japan, Australia on Pandanus, Latania,

 aa. Pygidium with single plate in each second incisura; plates arranged 

 0, 1, 3, those of each lateris situated, one near second lobe, one near 

 middle, and third near cephalic end; median pair of lobes large, 

 broadly rounded, strongly oblique, distinctly separated, finely ser- 

 rate; second pair of lobes small, incised, mesal lobelet much larger 

 than lateral, bluntly rounded, serrate; oraceratubae in each second 

 incisura adjacent to second lobe, two adjacent ones cephalad of 

 caudal plate of each lateris and one cephalad of each of other 

 plates; pygidial margin deeply concave between plates of second 

 incisurae and median lobes situated in concavity; genacerores ar- 

 ranged in five groups, 2-3(6-12)4-4; mesospiracerores 0-1. — South 

 Africa on Cyclostomum, Strychnos. Mpindensis Lindgr. 



SPECIES OF MYTILELLA

 notched on lateral margin, distant; second pair of lobes incised, 

 mesal lobelet slightly larger than lateral, notched on lateral margin,
