XENOLIMNOPHILA subgen. nov. 



Antennae Avitli seventeen segments in both sexes. Wings reduced to linear 

 pads in both sexes. Legs very long and slender, the tibiae with long spurs. 



This peculiar fly is well worthy of subgeneric rank. The genvis Zaluscodcs 

 Lamb(^) is based on Z. aucklandicus Lamb, a small, brownish-yellow fly from 

 the Auckland Islands. This group and Alfredia Bezzi(^) are apparently 

 degenerate species of Limnophiia, since they possess sixteen-segmented 

 antennae and other Limnophiline characteristics. Apparently these species, 

 together with L. aspkloptera Coq. and L. suhaptera Alex., of Western 

 North America, have no more claim to generic rank than have the 

 numerous subapterous species of TIpida and related genera, Xenolimnophila, 

 however, has seventeen-segmented antennae of a rather peculiar structure, and 

 the affinities of the group may be closer to Gynoplistia, in spite of the almost 

 simple structure of the antennal flagellum. 



LIMNOPHILA (XENOLIMNOPHILA) ZALUSCODES sp. nov. 



iSubapterous in both sexes ; legs long and slender, longer in the male than in 

 the female. 



6 Length, about 13-5 mm.; wing, 2 mm. Fore leg, femur, 13-5 mm.; 

 tibia, 18 mm.; hind leg, femur, 13-8 mm.; tibia, 19 6 mm. $ Length, about 

 Id 0-16 mm.; wing, 2 mm. Fore leg, femur, 7-9 mm.; tibia, 9-3 mm.; hind 

 leg, femur, 81 mm.; tibia, 11-4 mm. 



Kostrum and palpi dark brown. Antennae seventeen-segmented, moderately 

 elongate, dark brown, the scapal segments more reddish ; flagellar segments 

 subcylindrical, the inner face a little produced. Head reddish-brown, narrowed 

 behind. Mesonotum reddish-brown, the praescutum with two narrow darker 

 lines; pleura sparsely pruinose. Thorax small, the dorsum flattened as in most 

 subapterous Tipulidae. Halteres yellow, the knobs dark brown. Legs of the 

 male much longer than in the female, as shown by the above measurements, 

 giving the insect a spider-like appearance; coxae long and prominent, heavily
