ALEXANDER, CRANE FLIES FR. S. CHILE & TIERRA D. FUEGO. 23 



The antennae are dark brown, the second segment only 

 being light yellow. Mesonotum reddish gray, the praescutum 

 with three broad grayish brown stripes, the median stripe 

 being very broad, the interspaces correspondingly narrow, 

 almost obliterated opposite the anterior ends of the lateral 

 stripes which are thus practically confluent with the median 

 stripe; postnotum with a capillary dark brown line. Femora 

 brownish yellow, the tips broadly dark brown, a distinct 

 yellowish subapical ring; tibiae brownish yellow, the tips 

 narrowly darkened; tarsi dark brown. VVings subhyaline, 

 marbled with brown and gray; base of the wing, at the ar- 

 culus, darkened; the subcostal cell has two comparatively 

 small brown marks in addition to the brown base and tip; 

 of these marks, the first is smaller, the second larger, sub- 

 quadrate, passing into cells R and 1st Ri\ stigma dark brown, 

 including the end of cell 8c and connected with a large 

 brown mark at the end of the sector; asparsegray clouding 

 in the centers of cells R2, Rst R5, Mi, 2nd M2, Mé, Ci// and 

 more irregularly in the anal cells; a broad brown seam along 

 the forks of Cu\ veins dark brown. Venation: cell ilf i large 

 and ample; m-cu long and conspicuous. In the holotype, 

 cell 1st M2 is open in both wings by the atrophy of m. 



Abdomen dark brown, badly discolored in the types; the 

 caudal margins of segments two to seven broadly margined 

 with yellow. Ovipositor with the tergal valves slender, 

 long, the sternal valves much shorter, flattened, the tips 

 truncated.

Type in the Riksmuseum in Stockholm. 



Compared with Tipula magellanica, the present species 

 is seen to have the head clearer gray, the yellow femoral 

 ring more distinct and the wing-pattern very different, the 

 ground-colour being nearly hyaline, marbled with gray and 

 brown; the centers of the posterior cells are completely en- 

 circled by påle whereas in T. magellanica only the outer 

 ends are påle. It is probable that the two forms are rather 

 closely related, however.
