SPECIES OF DIASPIDISTIS 

 Pygidium of adult female with median pair of lobes largest, crenulate; 

 second and third pairs of lobes incised, lobelets subequal, crenulate; 

 fourth pair of lobes deeply incised into five subequal crenulate lobe- 

 lets; each lateris with seven or eight subequal projections or lata- 

 dentes; plates arranged 2, 1, 1, 0; second, third, and fourth incisurae 

 with broad lobe-like latadentis bearing oraceratuba; genacerores (15- 

 28)28-27. — Brazil on Myrtaceae multilobia Hemp. 



SPECIES OF PSEUDOPARLATORIA 

 a. Pygidium of adult female with median pair of lobes rounded, 

 minutely serrate, not notched; second pair of lobes divided into 

 three lobelets; plates of median incisura hardly projecting beyond 



lobes; genacerores 2-2(12-15)11-15. — Mexico on Myrtus 



serrulata Towns. & Ckll. 

 aa. Pygidium with median pair of lobes not serrulate. 



b. Pygidium with five groups of genacerores, 7-7(20-20)16-18; median 

 pair of lobes rounded at distal end, sides sloping, subbasal 

 notches wanting; second and third pairs of lobes incised; plates 

 of median incisura subparallel, longer than lobes. — Brazil on 



Nectandra. noacki Ckll. 



bb. Pygidium usually with four groups of genacerores, 0-2(9-15)7-10; 

 median pair of lobes quadrangular, deep mesal and lateral 

 notches; second and third pairs of lobes similar, incised, mesal 

 lobelet largest, lobelets triangular, bluntly pointed, often with 

 lateral notch; plates arranged 2, 1, 1, 0, those of median incisura 

 subequal to lobes, those of other incisurae longer than lobes; 

 each lateris with four slight projections, arranged in pairs, 

 caudal pair distant from third lobe; anus midway between vulva 

 and caudal margin, about three times its width from each. — 

 Florida, Mexico, Brazil on Persea, Drimys, Psidium, Oncidium, 

 Magnolia, peach. parlatoroides Comst. 



SPECIES OF PSEUDAULACASPIS 

 a. Pygidium always with two or more pairs of distinct lobes, median 

 pair large and prominent, second pair always small. 

 b. Pygidium with more than two pairs of lobes. 



c. Pygidium with second and third pairs of lobes incised, 

 d. Pygidium with median pair of lobes rounded, radiately 

 striate, moderately large, margins irregularly crenulate; sec- 

 ond pair of lobes consisting of two large subequal lobelets; 

 third pair of lobes consisting of two lobelets, mesal small- 

 est; fourth pair of lobes consisting of two very broad, low 

 lobelets, mesal low and conical, lateral gently convex and 

 serrate with five teeth; fifth pair of lobes represented by 

 two broad low processes; plates arranged 0, 1, 1, 1, 0, 0; 

 most of described lobes probably latadentes; latadentes of 

 each second and third incisurae as large as mesal lobelet, of 

 each third incisura smaller; genacerores 29-30(49-58)21-31. — 

 China, Japan on Eleagnus. crawii Ckll.
