 small, hardly longer than median pair of lobes, those of each lateris 

 much longer and arranged singly and distant from each other; margin 

 of lateris thickened, toothed; genacerores 5-5(24-27)29-35. Australia

SPECIES OF SCRUPULASPIS 

 a. Pygidium with second pair of lobes not incised.

 those of second incisura short, subdivided, pectinae-like,

 as broad as median lobe, with spine-like projection on mesal 

 corner, hardly longer than lobes, those of each lateris situ- 

 ated, small one near second lobe, one at middle, third at 

 cephalic end; caudal segment of preabdomen with two 

 plates on each side; median pair of lobes adjacent; gena-

cc. Pygidium with median pair of lobes triangular or subtriangu-
