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. Maxillae appearing as two lobes, contiguous on the median 

 line of the body, the palpi very long, extending laterad underneath 

 the eye to the antennas. Labium small, in the shape of a caudal 

 lobe behind the maxillae. 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. 

 Antennae 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
