with the exception of the base, light yellow. Antennal scape orange- 

 yellow, the flagellum black, the segments of the latter nearly cylindrical, 

 with a dense, microscopic white pubescence. Head light gray, the sides 

 of the vertex more brownish, set with abmidant setae. 



Mesonotal praescutum light gray, with three darker gray stripes, 

 the median stripe broadest, strongly narrowed behind, split by a 

 capillary velvety-black line; scutum light gray, each lobe with two 

 darker gray blotches; scutellum and postnotum darker gray. Pleura 

 dark colored, with a dense blue-gray pollen, the dorso-pleural membrane 

 conspicuously dull yellow. Hailteres brown, the extreme base brownish 

 yellow. Legs with the coxae blue-gray; trochanters yellow; femora 

 brownish-yellow, brightest at the base, the tips brownish black; tibiae 

 brownish black, darkest apically; the posterior tibiae with a broad, 

 indistinct, whitish, sub-basal band; tarsi black. Wings with a faint 

 yellowish tinge, brightest at the wing-base; costal cell more saturated; 

 subcostal cell dark ; stigma dark brownish black ; a broad dark brownish 

 black seam along the cord; wing-apex blackish, this occupying the end 

 of cell R2, nearly the apical half of cells Rz and R^ and part of Mi. 

 Venation: Rs short; R^ persistent; 2nd Anal vein running very close 

 to the anal margin so the 2nd Anal cell is very narrow. The wing is 

 strongly petiolate. 



Abdomen with the basal tergites yellowish, especially laterally, the 

 fifth to ninth tergites black; steniites paler; abdominal segments mar- 

 gined laterally and ringed caudally with paler. Male hypopygium not 

 conspicuous; ninth tergite rather small, the caudal margin almost 

 straight across or but feebly notched. Outer pleural appendage rather 

 small, flattened, greenish white in color, broadest at the base, tapering 

 gradually to the apex. Inner pleural appendage pale greenish, termi- 

 nating in two subequal blackened spines that are slightly divergent, 

 claw-like; a broadly spatulate blade projects toward the ninth tergite. 

 Ninth stemite with a small but deep V-shaped median notch. Eighth 

 sternite projecting caudally, the margin unarmed. 



Habitat: Japan.

Paratopotype, cf. 



This exquisite species is dedicated to the memory of my 

 mother, Mrs. Jane Parker Alexander. It shows numerous 

 points of resemblance to T. pedata Wied. and allied forms and 

 if the group Tiptilodina Enderlein is to be recognized as a valid 

 genus this species will probably have to be placed therein, 

 although the hypopygium is strikingly different from that of 

 the genotype of Tipulodina {pedata). For a discussion of the 

 status of the group Tipulodiyia, consult a paper by the writer, 

 Proceedings of the United States National Museum, vol. 49, 

 p. 184; 1915.
