The Crane-Flies of New York — Part II 871 



lines. Maxilla with dense tufts of long yellow hairs; outer lobe produced cephalad as a 

 hyaline, flattened blade which projects from prothoracic orifice when head is retracted. 



Pupa. — Length, 8..5-9 mm. 



Length of pronotal breathing horns, nearly 2 mm. 

 Width, d.-s., 1 mm. 

 Depth, d.-v., 1 mm. 



/ Head, thorax, and appendages dark brown; pronotal breathing horns similar, but terminal 

 half gradually paler, the tip almost yellow; abdomen pale brown. 



Cephalic crest consisting of two prominent lobes, each with three strong setae, the most 

 ventral directed outward; just before primary crest and lying between antennal bases, a very 

 low, slightly bilobed crest which is not setiferous. Labrum elongate, obtusely rounded at 

 apex and separating labial lobes, the latter produced caudally into subacute points. Maxillary 

 palpi stout at base, narrowed to tip (Plate XLVH, 221). Antenna short (in female sex, at 

 least), extending but a short distance beyond knee joints of fore legs. PronotRim (Plate 

 XLVn, 220) high, feebly carinate medially. Breathing horns separated basally, very long 

 and slender, sinuous, transversely wrinkled, at tip split into two flattened divergent lobes 

 (Plate XLVIL 222 and 223). Mesonotum very short and convex, with numerous black dots 

 which are most abundant anteriorly. Two small setae on either side behind wing axilla. 

 Lateral angles of mesonotum blunt, but tip produced into a slender setiferous tubercle. 

 Wing sheaths ending opposite tip of second abdominal segment. Leg sheaths short, ending 

 just before tip of third abdominal segment, hind legs a little longer than others. 



Abdomen with a narrow basal ring and a much broader posterior ring, the latter armed 

 before posterior margin with a transverse row of small black spines, strongest on pleura, 

 weakest on dorsum; on dorsum (Plate XL VI I, 224) the spines reduced in number, there 

 being from one to five (or in some cases none), and occurring only at or near ends of row; 

 ends of row with two setae; on either side of median line a group of three closely approxi- 

 mated setae; usually segments 2 and 3 have the spines weak or lacking; segments 4 to 6 

 with two spines, and segment 7 with one spine, but in some specimens the number is slightly 

 increased. Sternites (Plate XLVH, 225) with the intermediate segments (4 to 6) having 

 about twenty spines in an almost continuous row which as a rule is uninterrupted; at 

 each end of row about two strong setae; near base of posterior ring a narrow transverse 

 area with two setae at each end. Pleura with a few powerful spines, small or lacking on 

 basal segments, larger and more numerous on posterior segments, there being usually two 

 on segment 4, thre^; on segments 5 and 6, and four on segment 7; on pleura at about mid- 

 length of posterior ring and nearer dorsal side, three black setae in transverse alinement, 

 these somewhat longer on basal segments; opposite basal ring a stout seta. Female cauda 

 (Plate XLVn, 223) elongate; tergal valves slender, slightly upcurved, near apex with a 

 sharp black spine which is directed dorsad, laterad, and caudad; two weak setae on either 

 side before apex. Dorsum of segment 8 with four lobes; posterior pair elongate, slender, 

 curved, and divergent; anterior pair blunt, small, and more approximated; just ventrad of 

 these lobes a stout seta; pleural region with two powerful spines, above the more dorsal 

 of which is a stout seta; a seta near ventral margin.
