spicuous, shiny black stripes, the lateral stripes anteriorly subcontiguous with 

 the median stripe; scutum yellow, the lobes largely shiny black; scutellum and 

 postnotum light yellow. Pleura yellow; an obscure brownish area beneath 

 the wing-root and surrounding the base of the halteres; mesosternum faintly 

 brownish. Halteres long and slender, dark brown. Legs with the coxce and 

 trochanters reddish yellow; femora obscure yellow, the tips black; tibiae brown, 

 the tips narrowly dark brown; tarsi dark brown. Wings with a grayish \ellow 

 tinge, the costal cell light yellow, the subcostal cell a little darker; stigma elongate, 

 medium brown; veins dark brown. Venation as in the subgenus; ?n-ct{ present. 

 Abdomen with the basal tergites yellowish, longitudinally striped medially 

 and less distinctly laterally with jet-black, these three lines narrowly connected 

 across the caudal margin of the segments; segment five largely black, the tergitc 

 narrowly, the sternite more broadly, reddish at the base; segments six and seven 

 black, excepting the extreme base; segment eight reddish, the tergite darker 

 laterally and with a narrow, clear-cut median line, the sternite broadly darkened 

 laterally and medially; hypopygium bright orange. Male hypopygium with 

 the sclerites fused into a continuous ring; tergal region very narrow, the median 

 area slightly produced caudad and with a rounded median notch, the blunt 

 lateral lobes thus formed directed slightly proximad and densely set with short, 

 blackened spinules. Outer pleural appendage rather narrow, narrowed at the 

 base and apex, the latter bluntly rounded, the outer face of the appendage 

 sparsely provided with moderately long bristles; inner pleural appendage 

 moderately complicated in structure, divided into two arms, the cephalic arm 

 compressed into a blade, the posterior arm more slender. Ninth sternite with 

 a deep median incision filled with membranous tissue, the caudal proximal 

 angles provided with a brush of long hairs. Eighth sternite unarmed.

Type in the collection of the British Museum (Natural History). 



The female that is referred to this species has the antennal flagellum black; 

 the median praescutal stripe narrowly split behind Ijy a capillary pale line; the 

 subterminal abdominal segments are narrowly ringed basally with obscure 

 yellowish; seventh tergite yellow, narrowly but conspicuously margined laterally 

 and caudally with black; ovipositor with the tergal valves very slender and 

 divergent as in this group of species, the sternal ^'al\'es much shorter and com- 

 pressed. 



Tipula neavei, sp. n.
