THE CRANE-F Lies oF New York — Part II dele 
obliquely proximad to near median line, where there is a median lobe densely covered with 
long hairs. Epipharynx small, subquadrate, margin almost transverse, with about seven 
blunt teeth; sides of organ with long hairs which are directed backward. Labium (Plate 
XIV, 12) with submentum much narrowed on basal half, sides subparallel, thence expanded 
so that cephalic end is about twice as wide as caudal end; anterior lateral margins produced 
into blunt projections; mentum (Plate XV, 17) broadly subquadrate, anterior margin nearly 
transverse and with from twenty to twenty-two teeth forming an irregular comb. (There is 
considerable variation in the shape of this comb and in the form of the individual teeth com- 
prising it; usually the median third of the mentum is produced outward beyond the lateral 
parts, but this condition is not always well-marked; the individual teeth may be blunt or 
acute. In the specimen shown the normal condition is illustrated; the central lobe includes 
six teeth, and each lateral part about seven teeth, the lateral teeth being usually a little the 
larger; in some specimens the median lobe has the teeth very indistinct, while in others 
there is a conspicuous tendency for the median pair to unite into a single broad tooth.) 
Prementum pale basally, indistinctly covered with pale papillae; palpi lying close together, 
subparallel, the lateral parts with short, dense hairs, the ventral face with shorter papillae; 
each lobe bearing at tip a small, blunt, cylindrical knob which is slightly chitinized. Antenna 
(Plate XV, 18) short, almost cylindrical but slightly narrowed basally, bearing on truncate 
apex about five sensory papillae of various diameters, one being much the largest, two others 
being long and very slender; one of the papillae is bisegmented, the apical part being more 
slender than the basal part. (De Meijere [1916, fig. 14] shows his European Ptychoptera 
as having the antennae two-segmented and with the sensory papillae very different from 
the condition found in P. rufocincia.) Mandible (Plate XV, 19) strong and powerful; cutting 
edge subtriangular, with three large outer teeth and about six or seven small inner ones; 
of the larger teeth the outermost is the slenderest, the third is the largest and stoutest; small 
inner teeth subequal in length, the outermost stout, inwardly the teeth becoming more 
slender; mandible on ventral face near margin with two powerful setae, the posterior one 
often recurved, the anterior one directed forward. Maxilla (Plate XV, 19) with cardines 
roughly elongate-triangular, proximal angle acute, ventral face with three iarge setiferous 
punctures bearing several bristles of unequal length (the writer has not been able to locate 
setae on the middle puncture); outer edge of sclerite with a fringe of long hairs, longest at 
narrow inner end of segment; stipites roughly triangular, with a group of short spines at 
apex; palpi antenniform, stout, cylindrical, with sensory papillae at tip (one large papilla, 
about three of medium size, and three or four small ones); outer lobe of maxilla with a small, 
egg-shaped or subcylindrical, knob at its outer angle, below which the rounded lobe is 
densely clothed with long, pale hairs; caudad of these, along margin, a row of from six to 
eight powerful spines and a few long hairs.
