22 ARKIV FÖR ZOOLOGI. BAND 13. NIO 6. 



Abdomen dark brown, the incisures påle; the type is 

 discolored and the true coloration in fresh specimens is in 

 doubt. 



The male hypopygium (plate 2, fig. 10) has the ninth 

 tergite (Plate 2, fig. 11) large, with a very broad and deep 

 U-shaped median notch, the lateral lobes comparatively 

 narrow and obtusely rounded at their tips which are mar- 

 gined with erect delicate hairs. Ninth pleurite complete but 

 rather small, the ventral proximal angle produced dorso- 

 caudad as a slender lobe that is clothed with short erect 

 hairs; outer pleural appendage comparatively large and stout, 

 cylindrical, provided with long, divergent hairs; inner pleural 

 appendage long and slender, compressed, the caudal margin 

 with erect påle hairs, the apex produced into a compara- 

 tively slender beak that juts into the notch of the tergite. 

 Ninth sternite profoundly incised on the mid-ventral line; 

 on the caudal dorsal margin close to the pleurite with a 

 small globular lobe that is densely hairy. Eighth sternite 

 (plate 2, fig. 14) with a small semicircular appendage whose 

 apex is indistinctly bilobed by a small median notch, the 

 edges fringed with abundant long hairs. 



Hahitat. — Territory of Magallanes, Chile. 



Holotype, J*, Punta Arenas, Straits of Magellan, Novem- 

 ber 28, 1895 (Ohlin) Collector's No. 212. 



Type in the Riksmuseum in Stockholm. 



Tipula magellanicola, sp. n. 



Antennae dark brown, only the second segment light 

 yellow; mesonotum reddish gray, the praescutum with three 

 very broad dark brown stripes ; f emora with a yellowish ring 

 before the dark tips; wings subhyaline, marbled with brown, 

 the subcostal cell with four dark brown marks, one being at 

 the base and another at the tip of the cell; outer cells of 

 the wing with the centers gray; abdominal tergites dark, the 

 caudal margins broadly margined with yellow. 



Female. — Length about 19 mm.; wing, 16 mm. 



A rather small species that agrees in many respects with 

 T, magellanica, sp. n., but which presents several features 

 that cannot be reconciled with the condition found in the 

 latter species.
