1919] Alexander: Japanese Crane-Flies 331 



The genus Antoclia has, till now, been one of the most 

 compact genera in the Tipulidae. The discovery of Antocha 

 spinifer renders it necessary to subdivide the group. This 

 latter is a curious fly with long, stout, very hairy legs that 

 suggests in its general appearance a Trimicra or an Empedo- 

 morpJia rather than an Antocha. The venation alone is normal 

 for this latter genus. The discovery of the immature stages of 

 this isolated, generalized fly will possibly result in giving generic 

 rank to the group here proposed. 



Antocha (Proantocha) spinifer sp. n. 



Size very large (wing of male over 12 mm.); legs very long and 

 stout, the fore and middle legs provided with long, dense hairs, the hind 

 tibiae set with numerous tiny spines and with a large spinous tubercle 

 on the ventral side near the base. 



Male — Length about 9 mm.; wing, 12.3 mm. Fore leg, tibia, 

 7.S mm.; tarsus, 4.8 mm.; middle leg, tibia, 7.4 mm., tarsus, 3 mm.; 

 hind leg, tibia, 13.8 mm., tarsus, 3 mm. 



Rostrum short, dull yellow; palpi short, brownish yellow, the 

 terminal segments more infuscated. Antennae with the scape and basal 

 three or four segments of the flagellum dull brownish yellow, the 

 remainder of the antennae brown. Head dull yellow, very sparsely 

 light gray pruinose. 



Mesonotum dull brownish yellow, the praescutum darker brown 

 medially, the lateral margins pale. Pleura dull yellow. Halteres 

 pale, the knobs slightly brownish. Legs with the coxae and trochanters 

 dull yellow; remainder of the legs dull brownish yellow, only the terminal 

 tarsal segments brown; the long, dense hairs that cover the fore and 

 middle legs are dark brown and obscure the ground color of the sclerites 

 that bear them. The hind legs are covered with numerous blackened 

 spinous setigerous tubercles. Claws very long, dark browTi, longer 

 than the fourth and nearly as long as the fifth tarsal segment. Wings 

 milky white, stigma indistinct, faintly yellowish; veins brown, the 

 costa beyond the point of insertion of Sc tawmy and somewhat incras- 

 sated. Venation: r tending to be obliterated by atrophy; basal deflec- 

 tion of Cui far before the fork of M. 



Abdominal tergites brownish buff, with a distinct dark brown 

 median stripe that is interrupted at the posterior margins of the seg- 

 ments; stemites reddish, on the terminal segments darker, brownish, 

 the caudal margin of the segments broadly pale. 



Habitat: Japan.
