but the basal half entirely dark brown; eight and nine orange; sternites generally 

 similar, segments two to five with a brown posterior band, reduced to a triangle 

 on the second and third segments, the second segment with an additional brown 

 band near midiength; segments six and seven dark brown, the caudal margin 

 very narrowly yellow. Ovipositor with the tergal valves long and slender, 

 the tips curved a little ventrad; sternal valves compressed, the tips broadly

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



This magnificent crane-fly is apparently related to the much smaller and less 

 brightly coloured Tipulodina kinangopensis Riedel (British East Africa) and is 

 referred, provisionally, at least, to the subgenus Tipulodina Enderlein. The 

 white tibial bands in the present species suggest that this reference is correct 

 although the two African forms are very much more brightly coloured than the 

 numerous Oriental species as known. Tipula milanjii in its general appearance 

 suggests a large and handsome species of Nephrotoma. 



Tipula silinda, sp. n. 



Allied to T. jocosa; mesonotal praescutum yellow with three yellowish 

 stripes that are margined with brown; lateral and anterior margins of the prae-

 a dark brown spot above the base of the halteres; pleura yellow, faintly marked 

 with brown ; legs yellow, tips of the femora broadly blackened ; wings brownish 

 subhyaline, a darker brown spot at arculus, stigma dark brown, brown seams 

 along the cord; whitish obliterative areas beyond the arculus and before the 

 stigma; cell 1st M-2 ample; abdomen brownish yellow, margined sublaterally 

 with dark brown.

 leg, femur 14.5 mm.; tibia 17.8 mm.; metatarsus 16.2 mm. 



Frontal prolongation of the head brownish yellow; mouth-parts and palpi, 

 brown. Antennae with the scape and basal two or three flagellar segments 

 yellow, the remainder of the flagellum passing into dark brown ; verticils long 

 and conspicuous. Head obscure brown. 



Pronotal scutum light brown; scutellum more yellowish. Mesonotal

 margins distinct, the lateral margin broader than the proximal; at the anterior 

 ends of the lateral stripes a large, rounded, dark brown spot; anterior margin 

 of the praescutum narrowly dark bnnvn; scutum obscure yellow anteriorly, 

 dark brown posteriorly, this colour confluent across the median line; scutellum
