one in front and a much larger one behind bearing a small tooth in front and with its tip 
directed backward; lateral appendages, viewed from above, two in number, anterior one the 
larger, directed sharply backward, the second smaller, conical; ventral appendages, viewed 
from side, four, anterior pair the larger, posterior pair small, slightly behind the others. 
Dorsal appendages of abdominal segments (Plate LX X XV, 457) as follows: first segment with 
two pairs of appendages; anterior pair the shorter, conical, tips strongly recurved and bearing 
a tiny tooth on anterior face at about midlength; posterior pair much longer, with tips 
bent strongly backward, a small tooth on anterior face at about one-third length from base; 
segments 2 to 7 with four pairs of appendages, the first pair very small, conical, the second 
exactly similar but larger, the third and fourth pairs similar to appendages of first abdominal 
segment; the tiny anterior appendage largest on second segment, gradually becoming smaller 
toward end of body. Lateral abdominal appendages as follows: first segment with three 
pairs of appendages, the first directed laterad, the posterior two more recurved and directed 
caudad; segments 2 to 7 with four pairs of appendages, the first very small, situated at antero- 
lateral angle of segment, the other three subequal and directed caudad. Ventral abdominal 
appendages as follows: first segment with three pairs of appendages, which are successively 
larger from the short anterior one to the large posterior one; segments 2 to 7 with five pairs 
of appendages, the first three small, the fourth intermediate in size between them and the 
enlarged fifth pair. Eighth segment bearing spiracular disk and its lobes; dorsal side of 
field with a pair of long, slender lobes bent conspicuously cephalad. Spiracular disk (Plate 
LXXXvV, 461) small, oval, the two rounded-oval spiracles situated side by side and close to each 
other, inclined toward each other and capable of being closely appressed; ventral lobes of 
disk directed ventrad, inner faces of lobes with a conspicuous jet-black line, tip of each lobe 
ending in a sharp recurved hook. (Miiggenberg regards these lobes as representing the 
ninth abdominal segment.) Ventral surface of terminal segments with small protuberances. 
Head completely retractile into first thoracic segment. Mentum (Plate LX X XV, 458) with 
about seven teeth on either side, terminal pair the larger, separated by a V-shaped notch. 
Antenna (Plate LX X XV, 460) two-segmented, basal segment elongate-cylindrical, tip very 
short, thimble-shaped, with a diameter less than that of elongate basal segment. Mandible 
(Plate LXXXV, 459 and 460) many-toothed on inner face, with a prominent basal prostheca; 
mandibles working vertically against teeth of mentum. Maxilla (Plate LXXXV, 458) with 
palpi very short, broad, basal segment chitinized, tip narrow, pale. 
Pupa.— Length: male, 10.4-11.4 mm.; female, 10-13 mm. 
Width, d.-s.; male, 2—2.2 mm.; female, 2.2-2.6 mm. 
Depth, d.-v ; male, 1.9-2.2 mm.; female, 2.1-2.5 mm. 
Living pupae with pronotal breathing horns light yellow, the terminal half a little more 
brownish; a brownish black mark on prescutum; abdomen greenish, more yellow behind; 
dorsal spines clear light green thruout or with tips in some specimens a little infuscated. 
(In pupae preserved in alcohol, the greenish colors are lost, the dark brownish black mark 
of the mesonotal prescutum is irregularly U-shaped, with the arms of the U directed back- 
ward, and the dark color is produced caudad and cephalad along the dorso-median line; 
there is a triangular or rounded black spot on either side of the scutellar lobe; on the metano 
tum is a large blackish median blotch, which is continued cephalad onto the mesonota 
postnotum; the abdomen has an interrupted brownish black longitudinal line along eithe 
side of the midline of the dorsum; the posterior margin of each tergite is suffused wit
