bb. Pygidium with median pair of lobes entire, about as broad as 

 long, mesal and lateral margins subparallel, distal end broadly 

 rounded; second pair of lobes minute, inconspicuous, not incised, 

 distal end with two notches; plates not longer than lobes, ar- 

 ranged 0, 0, 7, those of each lateris arranged 1-1-1- (2-2) ; alta- 

 ceratubae apparently not prominent; brevaceratubae distinct; 

 mesospiracerores 3-4, metastpipacerores wanting; anus located 

 about eighteen times its width from caudal margin and about 

 three times cephalad of vulva; body elongate; caudad of and in 

 line with antennae, on each side a row of two or three blunt spiny 

 processes and pair of long setae. Uganda, islands of Lake Vic- 

 toria, Africa on unknown tree dura Newst. 



SPECIES OF OBLUCTASPIS 



Pygidium with median pair of lobes minute, inconspicuous, distal end 

 concave, mesal angle prolonged, sides parallel; second pair of lobes 

 smaller than median, triangular, pointed, lateral margin oblique; 

 plates small, short, broadened at proximal end, arranged 0, 1, 2, those 

 of each lateris distant; brevaceratubae small, smaller than lamacera- 

 tubae, promiscuously arranged; anus eight times its width from 

 caudal margin and three times cephalad of vulva. New Mexico on 

 Quercus. lobata Ferris. 



SPECIES OF SITULASPIS 



Pygidium with median pair of lobes large, prominent, broader than long, 

 distant, broadly rounded, lateral notch; second pair of lobes adjacent 

 to median pair, minute, bluntly rounded, as long as broad, one-fifth 

 width of median; plates slightly longer than median pair of lobes, 

 broadest at proximal end, arranged 0, 0, 1, adjacent second lobe; 

 altaceratubae wanting; brevaceratubae promiscuously arranged; anus 

 located four times its width from caudal margin and six times caudad 

 of vulva; setae small. Arizona on Condalia condaliae Ferris. 



SPECIES OF KUWANASPIS 



Scale of adult female very long and slender, sides parallel and usually 

 straight; second exuvia distinct; pygidium with median pair of lobes 

 short, divergent, slightly notched on mesal margin; latadentes round- 

 ed, serrate; plates large, much longer than median lobes, arranged 

 0, 3, those of each lateris placed one near a median lobe, one near 

 where third incisura would be located, and one midway between caudal 

 and cephalic plates; anus located cephalad of middle of pygidium; 

 dorsal oraceratubae numerous on caudal portion; latadentes few in 

 number. Japan on Phyllostachys. hikosani Knw. 



SPECIES OF INCISASPIS 



Pygidium with median pair of lobes distant, broadly divergent, project- 

 ing, oblique mesal margin with four to six notches; plates placed near 

 median pair of lobes, caudal three of each side shorter than others, 

 about 12 on each side, stout, blunt, usually curved; setae on dorsal 



aspect 6, minute; mesospiracerores 2. South Africa on Mitragyne
