the movable segments, at the caudal margin of the ridge and 
extending all around the segment; segmentation in abdominal 
segments 8 to 10 hard to determine; the eighth segment usually 
polished, its dorsal cephalic margin roughened and plate-like, 
with a row of punctures along the cephalic margin of the plate 
and opening cephalad; abdominal segments with two dorsal 
rows of tubercule scars and one ventral row; cremaster short, 
never exceeding two millimeters in length, broader than long 
and broadly and shallowly bifurcate at tip. Length 134’-21%’; 
girth about equal to length. 
Genus Basilona Boisduval. 
Face parts slightly elevated above the level of the append- 
ages; body surface roughened with spines; eye-pieces both 
present; invaginations for the anterior arms of the tentorium 
small and indistinct; clypeo-labral suture present; labrum 
with the length and breadth approximately equal; maxillae, 
measured on the meson, with the length twice the greatest 
width and one-half the length of the wings, triangular in out- 
line; tips of the tarsi of the first pair of legs usually meeting on 
the meson, but sometimes falling short so that the tips of the 
maxillae lie between them; tips of the second pair of legs 
always meeting obliquely on the meson; median line distinct 
on prothorax and mesothorax and sometimes showing on the 
cephalic half of the metathorax; metathorax with a prominent 
oblong roughened tubercule with fluted edges on each side the 
meson, extending half the distance between the meson and the 
margin of the first pair of wings; cephalic margins of abdominal 
segments 5 to 7 never with any indications of a plate or ridge; 
spiracular line curved slightly ventrad; cremaster long, bifurcate 
at tip. . 
This genus contains a single species, Basilona imperialis, 
found in the states east of the Mississippi. 
Basilona imperialis Drury. Color dark brown; body sur- 
face with indeterminate sculpturing and roughened with 
spines; antennae with the length four times the greatest width, 
the central axis set with a row of short spines directed caudad; 
face parts roughened with spines irregularly arranged, with 
the exception of a row extending cephalad from each proximo- 
lateral angle of the labrum to the proximal end of the antenna,
