THE CRANE-FLIES OF NEW YORK PART II 825 



Head capsule and mouth parts similar to those of D. stulta, already described, judging from 

 the scanty material of D. badia available for study. 



Pupa. Length, 8-8.5 mm. 



Width, d.-s., 1.1 mm. 

 Depth, d.-v., 1.2 mm. 



Head, thorax, and appendages dark brown; pronotal breathing horns light yellow; abdomen 

 greenish, the cauda chitinized, light brown. 



Labrum very broad, indistinctly bilobed at tip. Labial lobes large, broadly transverse, 

 posterior margin almost straight across. Maxillary palpi broad, tips truncated (Plate XXIX, 

 119). Lateral margins of cheeks flattened into ledges. 



Pronotal breathing horns large, flattened, in lateral outline (Plate XXIX, 118) subcircular or 

 nearly so, with a row of rather widely separated breathing tubercles along margin; as viewed 

 from above, horns directed proximad, so as to be contiguous at tips. A high median crest 

 on mesonotum behind breathing horns. Wing sheaths ending before apex of abdominal 

 segment 2. Leg sheaths ending far before apex of abdominal segment 4; as usual in this 

 division, the hind legs a little the shortest, the fore legs a little the longest. Abdominal 

 segments with a distinct basal welt which is thickly margined with microscopic curved hooks. 

 Lateral spiracles distinct, but small and probably nonfunctional. Female cauda with sternal 

 valves shorter than long tergal valves, the latter (Plate XXIX, 120) almost straight, each with 

 a powerful, acute spine on lateral margin at about midlength, this directed dorsad. Near the 

 margin of segment 8, on dorsum, a pair of rudimentary spiracles. 



Nepionotype Needham's Glen, Ithaca, New York, April 16, 1917. (No. 5-1917.) 

 Neanotype. Type locality, May 7, 1917. 



Genus Rhipidia Meigen (Gr. a fan) 



1818 Rhipidia Meig. Syst. Beschr. Zweifl. Ins., vol. 1, p. 153.

Larva.' Form rather stout, body terete. Abdominal sternitea 1 to 7 and tergites 2 to 

 7 with narrow transverse basal welts of chitinized points. Spiracular disk with indistinct 

 lobes. Head capsule massive, not unlike that; of Dicranomyia. Labrum broadly transverse. 

 Mandible very broad, flattened, with only three ventral cutting teeth. Maxilla of simple 

 structure. Antenna with apical papilla or segment very flattened, disklike. Hypopharynx 

 of two chitinized plates, each with about twelve comblike teeth. Mentum almost transverse 

 across anterior margin, with from nine to eleven teeth, the outermost fused. 



Pupa. Pronotal breathing horns elongate for this subtribe, about three times as long as 

 broad. Abdomen with transverse bands of spicules on tergites 3 to 7 and sternites 5 to 7, 

 and on extreme lateral parts of sternites 3 and 4. 



Rhipidia is a small to medium-sized genus (about thirty-five species) 

 having its center of distribution in the American tropics, with some 

 species occurring thruout temperate Europe and America and a less number 

 in Africa and the Oriental region. The genus is based on a sexual char-
