slightly longer than lobes adjacent to them, plates of each 

 lateris distant; genacerores 7-7(11-12)8-14. Australia on Eu- 

 calyptus. lidgetti Ckll. 



SPECIES OF LEPIDOSAPHES 



a. Pygidium with second pair of lobes not incised or at most only 

 deeply notched. 



b. Pygidium with median pair of lobes with their proximal ends 

 distant; plates of median incisura always much longer than 

 median pair of lobes. 



c. Pygidium with median pair of lobes deeply notched on mesal 

 and lateral margins; second pair of lobes smaller, notched on 

 mesal and lateral margins, bluntly pointed; plates arranged 

 2, 2, 3, large and broad, much longer than lobes, three plates 

 of each lateris near second lobe; lateris deeply incised and 

 finely serrate; genacerores 3-3(5-8)3-6. Australia on Mela- 



leuca. melaleucae Mask. 



cc. Pygidium with median pair of lobes not deeply notched, finely 



serrate or entire. 



d. Pygidium with median pair of lobes broad, broadly rounded, 

 finely serrate; second pair of lobes minute, inconspicuous; 

 plates arranged 2, 2, 2, those of each lateris adjacent near 

 second lobe; plates long and slender, distinctly longer than 



lobes; genacerores 3-3(7-10)7-9. Japan on Miscanthus 



arii Knw. 



dd. Pygidium with median pair of lobes subquadrangular, en- 

 tire; second pair of lobes similar in shape and smaller; 

 plates arranged 2, 2, 9, long and slender, much longer than 

 the lobes, those of each lateris arranged in groups of three; 

 lateres entire, not deeply incised; genacerores 1-7(15-15)15-22. 



Algeria on Ampelodesma. ampelodesmae Newst. 



bfo. Pygidium with median pair of lobes with their proximal ends 

 adjacent. 



c. Pygidium with four groups of genacerores, (3-3)4-4; median 

 pair of lobes longest on mesal half, lateral margin longer than 

 mesal, both sloping and finely serrate; second pair of lobes 

 much smaller and finger-shaped; plates arranged 2, 1, 1-3, those 

 of median incisura small, those of each lateris much larger 



than others. Japan on Calicornia,. Elaeagnus, Quercus 



craurii Ckll. 



cc. Pygidium with five groups of genacerores, 2-3(8-11)5-6. This 

 was described as variety of crawii Ckll. The figures of 

 Maskell and Leonardi and description of Cockerell are more 

 different than is implied by description by Maskell. Japan on 



Quercus. canaliculata Mask. 



aa. Pygidium with second pair of lobes incised. 



b. Pygidium with proximal ends of median pair of lobes distinctly 

 separated. 



c. Pygidium with only single plate or without plates in each 

 second incisura.
