Genotype. — Ozodiccra argcntina van der Wulp (Argentina). 



Enderlein (Zool. Jahrb., Vol. 32, pt. i, p. 27; 1912) places argen- 

 tina in his restricted genus Osodicera under the mistaken belief 

 that the antennae are unipectinate. In reality, the antennae in the 

 male sex, at least, are long-bipectinate and of a structure that di- 

 verges widely from all species of the genus Ozodicera. Likewise in 

 its wing-venation which is almost identical with the normal type of 

 the genus Tipula and the simple male hypopygium this species de- 

 parts from the compact type of Ozodicera. The presence of ten 

 pectinate flagellar segments and the petiolate cell M^ are ample char- 

 acters upon which to remove this fly from Ozodicera to a position 

 nearer the genus Tiptda, to which it is obviously more nearly allied. 

 The genitalia and color of the body closely resemble those of species 

 of the monilifera group of the genus Tiptda and it seems probable 

 that the true affinities of this fly are not far distant from this group. 



I am indebted to Senor Jorgensen for a specimen of this interest- 

 ing fly, taken at Esquina Grande, Catamarca, Argentina. April 7, 

 1915- 



Genus Tipula Linnaeus. 

 Tipula bruchi new species. 



Antennae bicolorous ; mesonotal praescutum with dark brown stripes ; legs 

 very long and slender, the tips of the femora and tibiae black ; wings with the 

 costal margin yellowish, the membrane clouded with gray and with four dark 

 brown blotches in the subcostal cell. 



Male. — Length about 17-18 mm.; wing, 18-19. 2 mm. 



Hind leg, femur, 14.2 mm.; tibia, 16 mm.; metatarsus, 21.6 mm. 



Frontal prolongation of the head slender, buffy, the sides darker; nasus 

 slender with long yellow hairs. Antennae short, the three basal segments dull 

 yellow, the remaining segments yellow with the basal enlargement black; ter- 

 minal segments more uniformly darkened ; verticils longer than the segments 

 that bear them. Head yellowish buff with a long dark brown medidn mark on 

 the vertex ; vertical tubercle rather conspicuous, brown medially, with an im- 

 pressed median furrow. 



Pronotum pale yellowish brown with three dark brown marks. Mesonotal 

 praescutum light buff with three dark brown stripes, the median stripe divided 

 by a broad pale line which, in turn, is split by a capillary dark brown median 

 line ; humeral region dark ; scutum buffy gray, each lobe with two large dark 

 brown marks; scutellum light brown with a dark brown median line; post- 

 notum grayish, the posterior margin and median area more grayish, the latter 

 with a capillary dark brown line. Pleura light buff, indistinctly spotted with
