 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, metaB(pi(raceroires avanting; 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-

 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. lohata 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
