pair of lobes large, broad, blunt, deeply notched 

 on mesal and lateral margins; second pair of 

 lobes incised, mesal lobelet much larger than 

 lateral, their margins entire or irregularly- 

 notched; plates arranged 2, 2, 6, those of each 

 lateris arranged in three equidistant groups of 

 two each; genacerores 5-14(9-24)8-18; mesospira- 

 cerores 3-6. — United States, Brazil, Europe, Japan, 

 Australia on elm, apple, pear, plum, willow, dog- 

 wood, poplar, etc. ulmi Linn. 



hh. Pygidium with five plates on each lateris; me- 

 dian pair of lobes large, broad, blunt, deeply 

 notched on mesal and lateral margins; second 

 pair of lobes incised, mesal lobelet much larger 

 than lateral; plates arranged 2, 2, 5, those of 

 each lateris arranged in three equidistant groups, 

 two at caudal end, two at cephalic end, and one 

 near middle; genacerores 10-10(14-14)21-23; meso- 



spiracerores 11. — New Zealand on Pittosporum 



multipora Leon. 



dd. Pygidium with median pair of lobes entire and rounded at 

 distal end, at most, only finely notched. 



e. Pygidium with mesal lobelet of each second lobe never 

 approximating median lobe in size, always much smaller, 

 f. Pygidium with median pair of lobes broader than long, 

 subtriangular in outline; second pair of lobes incised, 

 two lobelets subequal in length, margins entire; plates 

 arranged 2, 2, 6, those on each side of each second 

 pair of lobes distinctly shorter than others, each lat- 

 eris with plates arranged in three equidistant groups 

 of two each, two cephalic groups in deep indentations; 



genacerores 4-4(7-9)7-8. — Japan on Eurya 



euryae Knw. 



ff. Pygidium with median pair of lobes as long as or 

 longer than broad, sometimes faintly or irregularly 

 notched, distal end broadly rounded or truncated; sec- 

 ond pair of lobes incised, two lobelets with entire mar- 

 gins, mesal distinctly longer than lateral; plates ar- 

 ranged 2, 2, 4, those on each side of each second pair 

 of lobes subequal in length to those of median incisura, 

 each lateris with four plates in three equidistant 

 groups, two at caudal end, one near middle, and one at 

 cephalic end, those of two cephalic groups much smaller 

 than plates of caudal group; genacerores 1-7(7-13)7-12; 



mesospiracerores 2-3. — Bohemia, Japan on Pinus 



newsteadi Sulc. 

 ee. Pygidium with mesal lobelet of each second lobe equal to 

 median lobe in size; median pair of lobes as broad as long, 

 lateral and distal margins convex, converging, distal end 

 rounded, entire; second pair of lobes incised, mesal lobe- 

 let as large as median lobe, broader than long, subquad-
