1919 Dietz: Streptocera Group of Tipula, 87 



Allotype, 9 , has the ovipositor elongated, testaceous and 

 highly polished. The upper valves long and slender, pointed. 

 The lower valves nearly four-fifths the length of the upper 

 valves, obtuse at the apex. 



Tipula fragmentata sp. n. 



Reddish-brown with some lustre. Thoracic stripes distinct; ninth 

 tergite rounded posteriorly, with a subtriangular prolongation from 

 beneath the posterior margin. Pleural prolongation slender, twisted, 

 strongly inclined proximad. 



Male, length 1 1 millimeters, wing 13.5 millimeters. 



Head dark, margin of orbits whitish. Frontal prolongation rather 

 long, reddish-brown, shining, beset with black hairs. Nasus short, 

 obtuse, with a tuft of white hair at the apex. Palpi brown. Scape and 

 first flagellar joint of the antennae pale yellow, second flagellar joint 

 fuscous, remainder of antennae wanting. 



Thoracic stripes reddish-brown, with some lustre, separated by five 

 yellowish lines of the ground color; the median stripe divided by a 

 fine line. Pleura fuscous, dull. Scutum uniformly dark fuscous with a 

 faint lustre. Scute! yellowish and like the yellowish-fuscous postnotum, 

 shining. Legs slender, yellowish, femora yellow, apices fuscous; tibise 

 and tarsi yellowish-fuscous. Halters yellowish, knob wanting. Wings 

 grayish, stigma fuscous, the antestigmal spot faint interrupted in 

 cell 1st, M2; a hyaline spot beyond the stigma. 



Abdomen pale testaceous, shining, with median dorsal and lateral 

 stripes, the latter somewhat interrupted; the median stripe does not 

 extend upon the posterior tergites. Hypopygium (Plate XXX, Figs. 

 3 and 4) yellowish, pleural processes brownish. Ninth tergite rounded 

 posteriorly and from beneath its posterior margin extends a sub- 

 triangular process or prolongation. Ninth sternite deeply emarginate, 

 the emarginations almost entirely canceled by the narrowed end of 

 the prolonged eighth sternite, the latter with a brush of hair at its apex. 

 Pleural processes twisted, broad at the base, strongly attenuated and 

 twisted outwardly, inclined towards each other. The outer apical 

 appendage digitiform, extends obliquely inward. 



Holotype, cf, bears a label marked California (Bradley), 

 Type C. U. 



The specimen is in the collection of Mr. C. P. Alexander. 

 It was received in alcohol and practically dismembered. In its 

 hypopyginal characters, however, more especially the rounded 

 ninth tergite, it is at once differentiated from all the other 

 species. In its distinct thoracic stripes it resembles streptocera* 

 trypetophora and opisthocera. 



* A specimen, labeled T. streptocera, received from Prof. Doane, and another 

 from my collection, determined by him, have the thoracic stripes nearly ob.solete. 

 The same is also the case in nearly all the specimens of this species in my col- 

 lection.
