THE CRANE-FLIES OF NEW YORK PART II 931 



Coloration, pale brownish yellow. 



Form moderately elongated. Body covered with a sparse appressed pubescence. Spi- 

 racular disk (Plate LXXIII, 388) surrounded by five lobes, the dorsal one notably smaller 

 than the paired lobes; inner face of lobes with two subparallel brown lines, connected at 

 their outer ends to form narrow V's; disk marked with about six spots between spiracles, 

 the largest at base of ventral lobes; disk fringed with short hairs, which are interrupted for 

 a short distance between lobes. Anal gills moderately elongated, pale. (Beling describes 

 the three dorsal lobes of the disk as having the entire inner face shiny blackish brown, and 

 the ventral lobes merely margined with brownish; there would thus seem to be some varia- 

 tion in the character and degree of markings in this species.) 



Head capsule as in the tribe. Antenna with the basal segment stout, cylindrical, the 

 apical papilla very short, subpyriform. Mandible flattened; teeth large but very bluntly 

 rounded; apical tooth the largest, with a slightly smaller denticle en either side. 



Pupa. Length, 7-9 mm. 



Cephalic crest small; lobes pointed, directed ventrad, each bearing a short, stout seta. 

 Labrum narrow. Labial lobes large, divergent, caudal margin almost straight across. Sheaths 

 of maxillary palpi slender, narrowed at tip (Plate LXXIII, 390). Antenna moderately 

 angulated, ending just beyond base of wing. Pronotal breathing horns elongate-cylindrical, 

 directed ventrad and cephalad, with rows of breathing pores along dorsal face; ventral face 

 transversely wrinkled. MesDnotum moderately declivitous, at broad crest (Plate LXXIII, 

 389) armed with numerous black chitinized spines directed backward; these spines most 

 num rous proximally, interrupted by a medianispace, less numerous along shoulder; four setae 

 in a transverse row across mesonotum, two on either side of median line; lateral angle of 

 thorax broad and blunt, with two small setae, the outermost one the larger, the inner one 

 about half its size; an arcuated longitudinal row of about six pits extending from above 

 axil of wing toward crest of mesonotum. Wing sheaths short, ending before tip of second 

 abdominal segment. Leg sheaths ending opposite or slightly beyond tip of third abdominal 

 segment; hind legs much the longest, middle legs much the shortest, fore legs intermediate 

 (Plate LXXIII, 391). 



Abdomen with a rather strong armature of stout black spines on sternal segments, on 

 segment 3 this appearing as a small area of about ten spines, on either side of tips of hind 

 tarsi; tergal armature much weaker or lacking; lateral spiracles very distinct, tubular, in 

 cast pupal skin the principal tracheal trunks being very conspicuous. Female cauda (Plate 

 LXXIII, 393) with tergal valves the longest, terminating in sharp cylindrical points; sternal 

 valves much shorter, blunt at tips; dorsum of segment 8 with five blunt lobes. Male cauda 

 (Plate LXXIII, 392 and 394) with dorsal valves the longest, each terminating in a long, 

 subacute, chitinized spine directed dorsad and laterad and bearing before its tip two stout 

 setae; ventral lobes stout and blunt, longer than dorsal lobes. 



Nepionotype. Fell, between Oraefa and Heineberg, southeastern Iceland. 



Neanotype. Cast pupal skin, with type. 



Paratypes. Numerous cast pupal skins, with types (in the collection of the Copenhagen 

 Museum).
