lobes more or less deeply forked; genacerores 0-4(7-10)7-8. Japan on 

 Pinus. carticis-pini Lindgr. 



SPECIES OF ASPIDOIDES 



a. Pygidium with median pair of lobes entire. 



b. Pygidium with median pair of lobes large, long and broad, quad- 

 rangular, distal margin bisinuate; second pair of lobes much 

 smaller, elongate, bluntly pointed, slight mesal notch; third pair 

 of lobes triangular, as broad as long, entire; pectinae longer than 

 lobes, deeply lacinate, mostly unapectinae, arranged 2, 2, 3, 4, 

 those of each lateris in two groups; genacerores in two groups of 

 two pores each; anus located near margin of pygidium. New Zea- 

 land on Corokia. corokiae Mask. 



bb. Pygidium with median pair of lobes rectangular, entire, distal end 

 oblique; second and third pairs of lobes bluntly rounded, contrict- 

 ed at proximal end, with an outer shoulder, entire; pectinae nor- 

 mal in form, subequal in length to lobes, arranged 2, 2, 3, 2-4, those 

 of each lateris adjacent to third lobe; anus large, located near 

 middle of pygidium; genacerores represented only by two groups 

 of 1-4 cerores, probably represent pregenacerores ; dorsal oracera- 



tubae numerous. Australia on Hake comperei Marl. 



aa. Pygidium with median pair of lobes with mesal and lateral notches, 

 quadrangular, distal end broadly rounded; second pair of lobes 

 smaller, similar, unsymmetrical with short oblique margin; third 

 pair of lobes smaller than second, somewhat pointed; pectinae of 

 median and second incisurae as long as median lobes, furcapectinae, 

 others deeply lacinate, those of each lateris longest, cephalic four 

 often short, arranged 2, 2, 3, 4-5; genacerores arranged in two groups 

 of 4-6 cerores. Canary Islands on Olea tafiranus Lindgr. 



SPECIES OF MARLATTASPIS 



Pygidium with median pair of lobes sloping inwards, outer margin of 

 each with conspicuous notch and smaller notch on rounded lateral 

 margin at distal end; each lateris with two deep indentations cephalad 

 of lobes, and several pectinae, some are simple, plate-like and others are 

 broad and conspicuously forked; genacerores one or two on each side 



and sometimes with a single mesogenaceroris. China on Campanula 



implicata Mask. 



SPECIES OF FURCASPIS 

 a. Pygidium with median and second pairs of lobes subequal. 



b. Pygidium with each lateris produced near middle of its length 

 into prominent tooth-like projection with single furcapectina 

 cephalad of it; median pair of lobes quadrangular, broadly round- 

 ed, subtruncate, entire; second pair of lobes similar in size and 

 shape to median; third pair of lobes similar in shape to second, 

 smaller; pectinae subequal in length to lobes, furcapectinae, ar- 

 ranged 2, 2, 3, 1, those of each lateris distant from third lobe; 

 second and third incisurae with densariae; genacerores (4-5)4-4.
