outer gradates brown; Rs, shortly after separation from MA, forking 

 into 112 -f 3 and R4+5, considerably basad of point of coalescence of 

 So and Rl; R2+3 in right wing forking slightly distad of point of 

 coalescence of Sc and Rl and with an additional sectoral cross-vein 

 slightly basad of 2d r, in left wing R24-3 forking distad of 2d r and 

 with an apparently abnormal loop ending at 2d r and with no addi- 

 tional s; 2d r basad of s between R2 + 3 and R4+5 in both hind wings 

 (except additional abnormal cross-vein mentioned above) ; Cul with 

 three branches to margin in right wing, and fom' in left; seven outer 

 gradates in right hindwing, six in left; ten costal cross-veins before 

 pterostigma. 



Female genitalia (fig. 24, c): Eighth tergite shorter dorsally, 

 longer ventrally; ninth tergite with each lateroventral half large, 

 moderately elongate, with one posterior thick articulation ridge, dorsal 

 margin sloping gradually posteroventrally, anterior margin bent at 

 approximately midpoint at an angle, then sloping posteroventrally, 

 ventral margin straight for a short distance before cm-ving postero- 

 dorsally to articulation point; tenth tergite of almost equal length 

 throughout, tapering slight!}^ posteroventrally; ninth sternite with 

 apex rather sharply bent and a group of about five setal pits m apical 

 portion. 



Holotype: a female (pinned) from Puerto Varas, Llanquihue, 

 Chile, December 1926 (R. and E. Shannon) ; USNM 62259. 



It is seen from the account of the South American itinerary of 

 Shannon and Edwards (Edwards, in Alexander, Diptera of Patagonia 

 and South Chile, pt. 1, p. xii, 1929) into the southern Andes region 

 that collections at Puerto Varas were made on December 16. 



The holotj'pe has the left meso thoracic leg, the right antenna be- 

 yond the basal segment, and the tip of the left antenna missing (41 

 segments remaining in left antenna). The abdomen beyond the 

 anterior portion of the third segment is in glycerin; the right pair of 

 wings is mounted on a balsam slide. 



The male is unknown. 



This large species of Climacia is easily distinguished from most 

 species by the absence of any basal radiomedial streak or other pro- 

 nounced spotting in the forewing except the setal spotting. It is 

 separated from townesi, which also has no radiomedial streak, thi'ough 

 the bordered setal pits, basal position of 2d m in relation to 1st r-m, 

 color of veins m the hindwing (darkening of veins in vicinity of 1st r), 

 and the absence of the heavy anal streaking in chilena. C. carpenteri 

 also has the bordered setal pits similar to those of chilena, but, in 

 addition, possesses the radiomedial streak and antepterostigmal 

 spots. The pronotal coloration of chilena is distinctive. 



Whether the more basal forking of R2+3, the forking of MA at 

 the center of the wing, the additional s and m cross-veins of the right
