short, deeply incised, lateral lobelet usually mi- 

 nutely crenulate; plates arranged 2, 0, 2, 5, those 

 of each lateris in two groups, caudal group of one 

 or two near third pair of lobes and cephalic group 

 of two or three some distance cephalad of caudal 

 group; lateral margin of three caudal segments 

 of the preabdomen with three plates each. Mexi- 

 co on Mimosa. mimosarum Ckll. 



hh. Pygidium with genacerores 4-4(6-7)3-4; median 

 pair of lobes pointed, finely serrate, distant; sec- 

 ond pair of lobes incised, lobelets bluntly round- 

 ed, subentire, mesal lobelet larger than lateral, 

 lateral different in shape but subequal in size to 

 median lobe; third pair of lobes large, deeply 

 incised, subentire, lobelets bluntly rounded, mesal 

 lobelet much larger than lateral; plates arranged 

 2, 0, 1, 3, those of each lateris situated, one near 

 third lobe, one near middle projection, and other 

 at cephalic end; plates of median incisura as long 

 as or longer than median lobes; second and third 

 incisurae with blunt lobe-like projections bearing 

 oraceratubae ; each lateris finely serrate with lata- 



dentes. South Africa on Cynometra 



aberrans Lindgr. 



gg. Pygidium with median pair of lobes fused at proxi- 

 mal end, the median incisura represented by narrow 

 deep indentation, distal ends bluntly rounded, en- 

 tire; second pair of lobes small, incised, lobelets 

 adjacent to each other and median lobe; third pair 

 of lobes deeply incised, tooth-like projections; 

 plates arranged 2, 0, 2, 6, those of each lateris in 

 three groups, group of two near third lobe, three 

 equidistant near middle, and one at cephalic end; 

 plates of median incisura short and slender, much 

 smaller than other plates; postgenacerores four, 



others not determined. India on Aglaia 



travancorensis Lindgr. 



dd. Pygidium with each third lobe divided into three lobelets, 

 median portion largest and lateral portion notched, not 

 pointed; median pair of lobes notched on lateral and mesal 

 margins; mesal lobelet of second pair notched on lateral 

 margin; plates arranged 2, 1, 1, 2, all large and subequal 

 in size, much longer than lobes, those cephalad of second 

 pair of lobes sometimes f urcapectinae ; two plates of each 

 lateris distant; genacerores 7-8(10-15)14-19. Brazil on 



Baccharis. perlonga Ckll. 



cc. Pygidium with third pair of lobes consisting of considerable 

 number of minute lobelets, always more than five; median pair 

 of lobes large, rounded, entire; second pair of lobes incised, 

 two lobelets entire and subequal; plates arranged 2, 2, 1, 2,
