Tur CRANE-Firrs or New York — Part II 913 
° 
loward tip, shaped somewhat like an ear of corn, the surface delicately sculptured; besides 
is papilla, two or three much smaller cylindrical ones. Mandible (Plate LXV, 349) slender, 
nding in a blunt rounded lobe; ventral cutting edge with four blunt teeth, the second from 
e base very tiny and connected with the third from the base (in some specimens the teeth 
re very blunt and rounded, so that the cutting edge appears crenulated or wavy); a single 
ooth on dorsal cutting edge, immediately behind apex; prosthecal region of mandible with 
longitudinal slitlike opening filled with a dense row of long setae. Maxilla (Plate LXV, 
50) large and blunt, the outer lobe pale, roughly triangular, covered with numerous short 
airs, and with a few small sensory papillae near apex, surrounding palpus; inner lobe a 
ttle shorter, densely clothed and fringed with abundant long yellow hairs. 
Pupa.— Length, 6.2-7.3 mm. 
Width, d.-s., 0.7-0.8 mm. 
Depth, d.-v., 0.S-1 mm. 
Head, thorax, and appendages brown, when fully matured almost black; breathing horns 
ellowish; abdomen pale yellowish white. 
Cephalic crest of moderate size, consisting of two conical lobes directed forward and bearing 
stout seta on anterior face; immediately in front of these, a smaller transverse crest lying 
etween antennal bases. Front rather broad. Labrum triangular; lobes of labium triangular, 
ivergent; maxillary palpi elongate, moderately stout, narrowed at tips and extending beyond 
ints of fore legs. Thorax prominent, carinate medially before declivity. Breathing 
orns long and slender, sinuously curved, apices directed forward. Declivity of mesonotum 
late LXVI, 352) precipitous, at the crest armed with four powerful teeth, median pair the 
rgest, somewhat divergent, separated by median line; a few tiny setae on mesonotum, includ- 
g four in a transverse row at about the level of wing root. Wing sheaths ending opposite 
pex of second abdominal segment. (In fully matured pupae the characteristic venation of 
his genus shows on the wing pads.) Leg sheaths rather short, ending about opposite mid- 
ngth of fourth abdominal segment; hind legs slightly the longest, fore legs a little shorter, 
iddle legs conspicuously shorter, ending about opposite apex of fourth tarsal segment of 
re legs. 
Abdominal segments with two very narrow basal rings and a much broader posterior 
ng. Abdominal spiracles distinct on segments 2 to 7. Setae as follows: on pleura, one 
mediately caudad of spiracle, a second caudad and somewhat dorsad of spiracle opposite 
gsterior ring, another opposite anterior ring. Tergum with two setae on sides of posterior 
ng. Segment 8 with four blunt lobes on dorsum. Male cauda (Plate LXVI, 353 and 354) 
ith ventral lobe large, bluntly rounded at tips; dorsal lobes ending in two acute, chitinized 
oints which are widely separated and directed dorsad and slightly caudad, on outer face 
ith a small seta; near base of cauda on dorsum, surface tumid and bearing a small seta on 
ther side. Female cauda (Plate LXVI, 355 and 356) with sternal acidothecae much shorter 
an the very long tergal valves, these latter, just before apex, with an acute spine which is 
irected dorsad and with a seta on side. (When the pupa is nearly ready to transform 
the adult, the long, coarse bristles covering the body of the adult, and the chitinized 
nitalia, show thru the pupal integument.)
