convex, circular to broad oval, pitch-black; exuvize concolorous, very incon-

from A. longispinus by the contiguous lobes, the first pair of spines short, three 
following pairs very long, and thirteen strongly serrated and divided plates 
on each side of the lobes. It is evidently what Maskell recorded as A. longi- 
spina in Trans. N. Z. Inst., xxvii, 38. Div. Ent. 6086, ‘‘on Ohia tree, from W.

contiguous median lobes, which are long and slender, the absence of other 
lobes, the anal orifice at base of lobes, and especially the very long spines,
