with a small rounded protuberance on the anterior margin, widely 
separated from one another, this being the anterior end of the 
epipharynx underneath; the sclerite is yellow with a broad band 
across the middle and a second one across the caudal margin; the 
middle band indicates the position of the epipharynx beneath (see 
Plate I, Fig. 8). Maxilla large, the outer lobe conspicuous, en- 
larged cylindrical with a small knob at the tip. Mandibles (see 
Plate I, Fig. 6) long and slender with a long, strong apical point 
and from three to four smaller lateral teeth on the inner face near 
the tip, these teeth gradually smaller from the tip toward the base 
and thus presenting a somewhat comb-like appearance. Submental 
region (see Plate I, Fig. 4) moderately well-developed, the median 
split behind quite deep; the cephalic margin with subequal teeth 
arranged regularly, four on either side, and a much smaller apical 
tooth occupying the terminal notch. 
Pupa 
(Plate I, Fig. 1) 
Male. Head viewed from beneath: Mouth parts not promi- 
nent. Maxillas appearing as two lobes, contiguous on the median 
line of the body, the palpi very long, extending laterad underneath 
the eye to the antennae. Labium small, in the shape of a caudal 
lobe behind the maxills. No spines on the front, but there are 
several dark lines on the space between the eyes that have the 
appearance of long appressed hairs, the tips directed backward. 
Antenns not prominent, rather widely separated at the base, ending 
just before the origin of the wing-pad. A small bilobed protuber- 
ance shows between the antennal bases. 
Thorax with the pronotal breathing horns directed cephalad and 
laterad, rather pointed. Thoracic dorsum without lobes or spines. 
Tips of the metatarsi about on a common level, the fore pair of legs 
ending slightly beyond the tips of the other two pairs. Legs long, 
extending about midlength of the fifth abdominal segment. Wing- 
pad ending just beyond the tip of the first abdominal segment. 
Abdominal tergites with transverse rows of scattered setigerous 
punctures, which rows are fairly well defined on the anterior seg- 
ments, especially on the first segment, where there are some 20 to
