REPORT ON A COLLECTION OF JAPANESE CRANE- 

 FLIES {TIPULIDM, DIPTERA). 

 (Continued from Vol. XLV., p. 322). 



BY CHARLES P. ALEXANDER, ITHACA, N. Y. 



Subfamily: TIPULINM. 



Tribe: Dolichopezini. 



Genus: Nesopeza, gen. n. 



Antennae 13-segmented, segment 1 cylindrical with a few long 

 hairs; segment 2 oval-cylindrical; segment 3 very long, cylindrical; 

 the succeeding segments gradually shorter, the last very slender. 

 Palpi with the apical segment slender, as long as all of the preceding 

 segments combined. Legs excessively long and slender. Wing- 

 venation as in Dolichopeza Curtis (lack of cell 1st M2, basal deflec- 

 tion of Cui far before the fork of M, etc.), but the radial sector is 

 very elongate, angulated at origin, almost as long as R3 beyond 

 the fork, Rs not short and simulating a cross-vein. 



Type of the genus: Dolichopeza gracilis, de Meij. 



Nesopeza gracilis de Meijere. 



1911. — Dolichopeza gracilis de Meijere ;Tijd.voor Ent., vol. 54, 

 p. 60, 61; pi. 4, fig. 46. 



One 9 from Tokyo, Japan; August, 1912. (Vial D.) 



This new genus represents one extreme of the Dolichopeza 

 group and Scamboneura Osten Sacken, the other. In this genus 

 the radial sector is extremely elongated, in Dolichopeza Curtis 

 almost transverse and simulating a cross-vein, while in Scamboneura 

 the origin of the sector is farther distad than the tip. See my key 

 to the Dolichopezini, Psyche, vol. 19, p. 64. (April, 1912.) 



Genus: Dictenidia Brulle. 

 Tribe: Ctenophorini. 

 Dictenidia fasciata Coquillett.

 One o 71 from Tokyo, Japan, Aug. 1912 (Vial 39). It agrees 

 very closely with Coquillett's description. The specimen offers the 

 following measurements:
