teeth; the more apical ones larger, the basal one very broad and truncated; two or three 

 dorsal teeth, gradually lessening in size from tip of mandible toward base; two conspicuous 

 tufts of long setae at prosthecal region; base of mandible on dorsal side with a large, some- 

 what curved, plate overlying head sclerites. Maxilla (Plate XXXIV, 152) with cardo long 

 and narrow, transverse, with three conspicuous setiferous punctures bearing long setae; 

 outer lobe short and stout, a little narrowed to tip; palpus rather large, flattened, disklike, 

 the truncated apex with several tiny hyaline pegs; inner lobe with a sensory bristle and 

 an inner fringe of rather short hairs. 



Pupa. Length, 6.4-7 mm. 



Width, d.-s., 1.2-1.3 mm. 

 Depth, d.-v., 1.2-1.6 mm. 



Mouth parts, wing sheaths, and leg sheaths rather dark brown; thoracic dorsum and 

 abdomen light yellowish brown; pronotal breathing horns dark brown, passing into light 

 yellow on apical third or quarter; mesonotal prescutum retaining its light color even in old 

 pupae and those preserved in alcohol. 



Cephalic crest (Plate XXXV, 155) represented only by a small bilobed protuberance 

 behind and between antennal bases, each lobe tipped with a very tiny seta. Labrum short, 

 bluntly rounded at tip. Labial lobes appearing as a large, roughly quadrate plate, a little 

 narrowed behind and with all angles rounded. Sheaths of maxillary palpi very long and 

 slender, rather stout at base, tapering to blunt tip. Antennae not conspicuous, rather 

 widely separated at bases, ending just before or opposite origin of wing pad. 



Pronotal breathing horns (Plate XXXV, 154 and 155) long and conspicuous, cylindrical, 

 gradually tapering to subacute and flattened apices; horns directed laterad and cephalad, 

 widely divergent. Thoracic dorsum without lobes or spines. Wing sheaths extending to 

 just beyond end of second abdominal segment. Leg sheaths extending to about midlength 

 of sixth abdominal segment; tarsal sheaths ending almost on a common level, the fore legs 

 being a very little the longest, the middle legs a little shorter. Abdominal tergites with trans- 

 verse rows of scattered punctures; on tergites 2 to 6 a transverse band of subchitinized points, 

 producing a shagreened appearance; these bands located on basal rings of segments excepting 

 the last two, which are on extreme ends of segments 5 and 6; on sternites the bands appearing 

 only on segments 7 and 8, the other sternites being largely concealed by the unusually long 

 leg sheaths; band on segments very broad, but narrowly interrupted medially. Male cauda 

 with ventral lobes bluntly rounded and inclosing pleural appendages of adult (in fully 

 colored pupae these show thru the pupal skin as from twelve to fifteen strong, chitinized 

 points on the inner posterior face) ; dorsal lobes (Plate XXXV, 157) very short and blunt, and 

 closely approximated medially; on eighth tergite a broad rectangle of five lobes, including 

 an anterior and a posterior lobe on either side and a much broader anterior median lobe; 

 just proximad of anterior lateral lobes a large and distinct spiracle, in the cast skin with the 

 large tracheal trunks still attached. Female cauda (Plate XXXV, 156) stout, tergal valves 

 a little longer than sternal valves and a little upcurved.
