Genus TIPULA Linnaeus. 

 19. Xipula carizona new species. 



Monilifera group; wings light brown, subhyaline markings scanty; abdo- 

 men yellowish brown, trivittate with darker brown. 



Male, length, 11.4-13.2 mm.; wing, 13.3-14.5 mm.; antennae, 9 mm. 



Palpi dark brown ; antennae of the monilifera type of structure, scapal 

 segments light yellowish brown, third segment with the basal half yellowish 

 brown, passing into dark brown at the tip, remainder of the antennae dark 

 brown ; frontal prolongation of the head brown with a gray bloom ; front, 

 vertex and occiput light gray with three longitudinal brownish stripes, one 

 median and one along either inner margin of the eye. 



Pronotum light gray, with a very narrow and indistinct median brown 

 mark, sides of the sclerites darker. Mesonotal praescutum light gray, with 

 darker longitudinal stripes as follows : a very narrow brown median stripe 

 extending the length of the sclerite, on cither side of this, narrowly separated 

 by a strip of the ground color, is a gray band, behind the pseudosutural or 

 humeral region begin the abbreviated grayish lateral stripes, sides of the 

 sclerite brown, much of the gray ground color is speckled with dark brown ; 

 scutum gray, with the lobes brown, a dark brown median spot on the caudal 

 margin of the sclerite, this running back across the scutellum as a median 

 vitta; scutellum very pale gray, with the caudal margin broadly dark brown; 

 postnotum clear gray, with a conspicuous dark brown median stripe and a spot 

 of the same color on the sides of the basal half of the sclerite. Pleurae light 

 gray, with large indistinct markings of brown. Halteres light brown, the knob 

 a little darker. Legs, coxae light brown, with a gray bloom, trochanters and 

 femora light brown, the latter broadly dark brown apically, tibiae brown, the 

 dark tip still broader, tarsi dark brown. Wings with a rather uniform light 

 brown suffusion, stigma a little darker brown, a subhyaline spot beyond the 

 stigma in cell zd R„ a second along the cord, most noticeable in cells ist M. 

 and base of 71/^. Venation as in PI. 4, fig. 7. 



.Abdominal tergites yellowish brown, with a dark brown median stripe 

 extending to the 8th segment, lateral margins of the sclerites dark brown ; 

 stcrnites yellowish, becoming much more infuscated along the apical segments. 

 Male hypopygium : 9th tergite from above with the caudal margin deeply and 

 broadly incised, this broad notch with a median protuberance which is again 

 incised by a triangular cut, ventral margin of the 9th tergite produced entad 

 into a rounded lobe. 8th sternite produced caudad into a long flat point, 

 which is densely clothed with long hairs, viewed from beneath this appendage 

 is seen to be constricted at the extreme base, soon widening. 9th sternite 

 rather large, the pleural piece complete, oval, bearing three appendages, the 

 more dorsal being long, slender, fleshy and directed dorsad, clothed with long 

 pale hairs; the more ventral appendage projecting caudad from the ventro- 

 caudal angle of the sclerite, short, densely clothed with short appressed hairs ; 

 the median appendage is largest and longest, its base about as wide as the 

 length of the pleura, the appendage narrowed before the enlarged axe-like tip.
