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 LXXX V, 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 

 LXXXV, 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 

 endmg in a sharp recurved hook. (Miiggenberg regards these lobes as representmg the 

 ninth abdominal segment.) Ventral surface of terminal segments with small protuberances. 

 Head completely retractile into first thoracic segment. Mentum (Plate LXXXV, 45S) with 

 about seven teeth on either side, terminal pair the larger, separated by a V-shaped notch 

 Antenna (Plate LXXXV, 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. IMa.xilla (Plate LXXXV, 458) with 

 palpi very short, broad, basal segment chitinized, tip narrow, pale. 

 Pupa.— Length: male, 10.4-n.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 mesonotal 

 postnotum; the abdomen has an interrupted brownish black longitudinal line along either 

 side of the midline of the dorsum; the posterior margin of each tergite is suffused with
