NEW NEARCTIC CRANE-FLIES (RHYPHID^ AND TIPULID^, 



DIPTERA) PART VI L 



BY CHARLES P. ALEXANDER, STATE LABORATORY OF NATURAL HISTORY, URBANA, 



ILLINOIS. 



Family RhypliidcB. 

 Trichocera colei, new species. 



Thoracic stripes indistinct; wings light grey, yellowish at the base, a faint 

 brown cloud on r-ni; male hypopygium conspicuously enlarged. 



Male. — Length, including the hypopygium, about 7-7.5 mm.; wing 6 mm. 



Rostrum and palpi dark brown. Antennas of the male setaceous, black. 

 Head dark grey. 



Mesonotum brownish grey without distinct stripes, the posterior half of the 

 scutellum yellowish; postnotum dark. Pleura dark brown, sparsely grey 

 pruinose. Halteres pale, the knobs dark. Legs light brown, the coxse, tro- 

 chanters and bases of the femora paler. Wings with a faint grey tinge, the 

 base of the wing yellowish; stigma brown, diffuse; a brownish cloud on r-m. 

 Venation: Sc ending slightly before r; R2+3 a very little longer than R2 before r. 



Abdomen dark brown, the incisures paler. Male hypopygium conspicuous, 

 very large for this genus of flies. Pleurites with a group of setae near the distal 

 end on the inner face. Pleural appendage longer than the pleurite, at the 

 apex enlarged into a blackened lobe which is densely covered with short, erect, 

 yellowish hairs; on the dorsal inner face near the base of this lobe, a slender 

 cylindrical arm. Penis-guard broad at the base, rapidly narrowed to the blunt 

 tip. Gonapophyses in the form of two strongly divergent chitinized horns. 



Habitat. — Oregon. 



Holotype. — cf, Forest Grove, Washington Co., November 11, 1918, (F. 

 R. Cole). Type in the collection of the author. Paratype. — d", Vancouver, 

 Washington, Dec. 12, 1918, (Wm. Giles); reared from turnips. In the collec- 

 tion of the U. S. National Museum, Chittenden, No. 2772. 



The conspicuous male hypopygium will easily separate the fly from any 

 of the known American species. The species is dedicated to Mr. Frank R. 

 Cole to whom I am indebted for many favours.
