354 DIPTEROUS GENUS TIPULA 



9 , Length, 20 mm. ; wings, 17.5 mm. 



Anterior leg: femur, 8.5 mm.; tibia, 11 mm.; tarsus, 12 mm. 



Similar to male. Antennae bent back do not reach the base of the ^Yings. 

 Abdomen with ill-defined median fuscous ventral line. Ovipositor testa- 

 ceous, upper valves very slender, much longer than the basal pieces; lower 

 valves shorter, parallel and very little wider than the upper valves; wing 

 pattern very pronounced, first axillary cell margined with white. 



Holotype: cf ; Jemez Springs, New Mexico. August 12, 1913.

Allotype: 9 ; Jemez Springs, August 22, 1913. 



Paratypes: Jemez Springs, July, August, six males, one female. 

 All in author's collection. 



In general appearance this species closely resembles Tipula 

 fallax, rohweri, dathrata and alia. From fallax it differs by its 

 general darker appearance, the heavy fuscous pleural stri^^e ex- 

 tends to the mesopleural suture and the lower process of the lat- 

 eral appendage is clawlike and not pendulous and membranous 

 as in fallax; the second basal and anal cells are margined with 

 whitish. In wing pattern, doanei scarcely differs from the 

 other three above mentioned species. In rohweri the fuscous 

 pleural line is less distinct, broken, and scarcely reaches the meso- 

 sternal suture, the lower process of the lateral appendage is more 

 slender and without toothlike process. The first posterior cell in 

 dathrata is white in basal third only and alia has the venter strongly 

 infuscate, especially towards the base. The lateral appendage of 

 the last two species has three processes. 



It gives me pleasure to name this species in honor of Professor 

 Doane, for his contributions to our knov/ledge of the North Amer- 

 ican Tipulidae, and also for assistance extended to the writer in 

 naming material and otherwise. 



Tipula doanei var. bifida var. n. 



Two male specimens from the same locality differ as follows : The whole 

 insect has a distinctly darker appearance. Underside of rostrum yellowish 

 fuscous; the dividing line of the middle mesonotal vitta is linear through- 

 out. The toothlike process of the lower process of the lateral appendage is 

 mjich larger, giving it an almost bifid appearance. A subfuscous patch in 

 first basal cell along first longitudinal vein near the base, a subfuscous 

 patch behind the outer white spot in second basal cell, two similar patches 

 in basal half of anal cell. 



Length, 16 mm.; wing, 15 mm.
