Through the kindness of Professor Cockerell I have received 
some of the original material from which oesculi was described. 1 
have compared the two species as follows: 
A. sub. sp. solus compared with 
Scales of solus uniformly darker 
Color of exuviae of solus lighter 
Texture of scale very delicate. 
Scale flat. 
Margin*of scale irregular and 
frequently indistinct. 
Broad median lobe notched 
once on lateral margin; lobe 
bears spine. 
Laterad of lobe is an incision 
bordered by club-shaped thick- 
enings. 
Line of U-shaped openings 
extending cephalad in body wall 
from the incision. 
Caudad of incision one forked 
plate. 
Laterad of this incision from 
two to five plates. 
Laterad of median lobe on 
last segment are three pairs of 
spines, each pair composed of 
one spine from each side of the 
body wall, then a single spine 
near penultimate segment, mak- 
ing in all seven spines on lateral 
margin of the segment. 
Laterad of first incision is a 
second incision but little smaller 
than the first; the sides of this 
bear club-shaped chitinous pro- 
cesses. 
Dorsal glands numerous. 
A. aesculi, taken from the original 
material. 
than scales of msculi. 
than exuvias of cesculi. 
Texture firm. 
Scale slightly convex. 
Margin of scale distinct. 
Same. 
Laterad of lobe is an incision 
filled with chitine forming a 
crescent-shaped structure. 
Same. 
Same. 
Laterad of this incision never 
more than two plates. 
Only three spines on lateral 
margin of last segment aaid all 
arising from ventral surface. 
The body wall at this point is 
entire and no additional chitine 
is apparent. 
Dorsal glands numerous.
