THE CRANE-FLIES OF NEW YORK PART II 865 



region roughened by tiny groups of parallel ridges. Mental region consisting of a heavily 

 chitinized transverse bar which is delicately grooved, enlarged at ends, and articulating with 

 a small ventral bar. Antenna (Plate XLIV, 206) long and slender; basal segment short and 

 broad; second segment elongate-cylindrical, bearing at its tip a small, hyaline, sensory papilla 

 which appears delicately crosshatched by fine impressed lines, this papilla elongate-oval 

 with the apex broadly rounded; a long hair near base of this papilla and about twice its length. 

 Mandible (Plate XLIV, 207) long and powerful, the tip produced into a slender point, the 

 cutting edge at about midlength with a single row of three or four flattened, bladelike teeth 

 which are truncated at their tips, these teeth varying considerably in their shape and relative 

 proportions. Maxilla with outer lobe elongate, the base strongly chitinized, this chitinized 

 part continuing up margin of lobe almost to tip, the apical part nearly hyaline; at about 

 midlength, the small palpus and a long seta. Esophagus enlarged, the walls thickened and 

 roughened. 



(A slide of a larva that was supposed to belong to this species differs considerably from 

 the material described above. The antenna is much shorter, with the apical tubercle much 

 larger and elongate-cylindrical; the mandible has the teeth fewer and more acute, quite 

 as shown by De Meijere for Limnophila [Phylidorea] ferruginea. It is probable that this 

 species likewise is a Phylidorea.) 



Pupa. Length, 14-16 mm. 



Width, d.-s., 1.8-2 mm. 

 Depth, d.-v., 1.9-2.2 mm. 



Breathing horns pale whitish brown, a little darker at base; remainder of body dark 

 brownish black, abdomen a little lighter-colored; incisures of segments, and pleural line, pale. 



Cephalic crest very small, inconspicuous, bilobed, each principal lobe subdivided into 

 two smaller lobes terminating in a small seta; another seta on anterior face. Labrum 

 rather blunt and truncated at apex. Labial lobes terminating in sharp points projecting 

 proximad. Maxillary palpi short and stout, tapering to blunt tips (Plate XLV, 210). 

 Antenna of male elongate, reaching to beyond midlength of wing sheath; antenna of female 

 short, ending at about one-fourth length of wing sheath. Segments of antenna cylindrical, 

 unarmed. 



Pronotal breathing horns (Plate XLV, 209) short, broad, somewhat compressed, a little 

 pointed at tip. Thorax broad and deep, the pronotum flattened, carinate medially. 

 Mesonotum high, convex, transversely wrinkled. Wing sheaths ending some distance before 

 tip of second abdominal segment. Leg sheaths short, ending before tip of third abdominal 

 segment, the hind legs a little longer than the other legs, which end about on a common 

 level. 



Abdomen depressed, lateral margin carinate. Abdominal segments distinct, incised, each 

 segment divided into two a'nnuli, basal one about half length of posterior one. Basal ring 

 on dorsum with a transverse single, or somewhat double, row of small subacute spines, which 

 are more numerous and larger on mid-dorsal area. Pleura unarmed. Sternum with an 

 oblique flattened lobe or wing on each side, directed caudad and proximad; between these 

 lobes a more or less broken transverse row of from six to twelve slender tubercles. Posterior 

 ring on dorsum with numerous small scattered tubercles. Pleura with a small circular 

 spiracle near base and close to dorsal margin; a slender seta near spiracle and ventrad of it;
