 caudal three or four of each lateris unapectinae, cephalic 

 two to four plates; dorsal oraceratubae numerous; gena- 

 cerores (5-7)3-6; setae large and prominent, projecting 



beyond lobes. Florida on saw palmetto 



pseudospinosa Woglum. 



ff. Pygidium with anus five or more times its own width 

 from caudal margin; median pair of lobes quadrangular, 

 distinct mesal and lateral notches; second pair of lobes 

 long and narrow, longer than broad, entire, bluntly 

 rounded; pectinae long, subequal in length to lobes, 

 those of median incisura narrow, arranged 2, 2, 6-8, three 

 caudal pectinae of each lateris longest and broadest, 

 those cephalad of these much shorter, varying from 

 furcapectinae to plates; dorsal oraceratubae numerous; 

 genacerores (9-12)6-8; setae small, not projecting beyond 



lobes. New Jersey on Oxycoccus oxy coccus Woglum. 



ee. Pygidium with second pair of lobes with notch. 



f. Pygidium with seven or eight pectinae on each lateris; 

 median pair of lobes large, broadly rounded, proximal 

 portion constricted, distinct mesal and lateral notches; 

 second pair of lobes strongly constricted on proximal 

 portion, distal portion broadly rounded, lateral shoulder 

 and lateral notch; with shoulder-like thickening, may 

 represent third lobe; pectinae subequal in length to 

 lobes, deeply toothed, arranged 2, 2, 7-8, those of each 

 lateris adjacent to second lobe; dorsal oraceratubae 

 prominent; genacerores 2-4(3-3)3-4; mesal calles oblique, 

 not so distinct as oblique lateral calles; anus about 

 twice its own width from caudal margin. China on 

 Abies. meyeri Marl. 



ff. Pygidium with three pectinae on each lateris; median 

 pair of lobes short and broad, quadrangular, prominent 

 lateral and mesal notches, distal margin bluntly round- 

 ed ; second pair of lobes broader than long, oblique, feebly 

 crenulate or notched; pectinae subequal in length to 

 median lobes, narrow, deeply lacinate, arranged 2, 3, 3, 

 those of each lateris adjacent to third lobe; anus oval, 

 near median lobes; genacerores 4-4(7-7)3-4. California 

 on Arctostaphylos arctostaphyli Ckll. & Rob. 



dd. Pygidium with median pair of lobes entire or with lateral 

 notch only. 



e. Pygidium with median pair of lobes about as broad as long, 

 broadly rounded, mesal margins divergent, entire or with 

 indistinct lateral notch; second pair of lobes much smaller, 

 subminute, triangular; pectinae with few lacinations, ar- 

 ranged 2, 2, 7, caudal pectinae distinctly lacinate, cephalic 

 two or three modified into plates; lateres serrate cephalad 

 of plates; genacerores 3-4(8-9)5-7. Aspidiotus hartii luntii 

 Ckll. West Indies on yam. hartii Ckll.
