358 Dr. C. P. Alexander on African Crane-flies 



intermediate pair ending before the suture, very narrowly 

 and indistinctly separated from one another by a pale 

 capillary line ; pseudosutural fovese large, pale ; no tuber- 

 culate pits ; scutum obscure yellowish, each lobe Avith two 

 confluent dark brown spots, the more lateral being con- 

 tinuations of the lateral prsescutal stripes ; scutellum and 

 postnotum yellow. Pleura pale yellow. Halteres with the 

 stem yellow, brightest basally, the knobs dark brown. Legs 

 with the coxae and trochanters yellow ; remainder of the 

 legs broken. Wings pale greyish subhy aline, the stigma 

 very indistinct and ill-defined ; veins dark brown. Venation : 

 Sc-i ending opposite the fork of Rs ; Sc 2 some distance from 

 the tip of Sci, the latter vein alone being a little longer 

 than R 2 +3 > R s rather long, gently arcuated ; R 2+3 almost 

 in alignment with Rs, rather short, a little longer than the 

 deflection of i? 4+5 ; r on R 2 about, or less than, its own 

 length beyond the fork of R 2+3 ', R\ beyond r, about equal 

 to Sc 1 alone ; basal deflection of R i+5 and r-m in oblique 

 alignment ; cell M x lacking ; cell 1st M 2 open by the 

 atrophy of the outer deflection of M 3 ; cell 2nd M 2 a little 

 more than twice its petiole ; basal deflection of Cui beyond 

 the fork of M, the fusion of Cu x and M z being about two- 

 thirds the length of the basal deflection of Cu x . 



Abdomen light reddish brown ; tips of the terebra broken 

 in the unique type.

The legs are lacking in the unique type, and it becomes a 

 rather difficult matter to place this fly generically. How- 

 ever, there seems no doubt in my mind but that the above 

 reference is the correct one.

Antennse small, the flagelluni yellowish; general color- 

 ation dark brown ; halteres yellow ; legs yellow, the tips of 

 the femora broadly, of the tibiae narrowly, dark brown ; legs 

 with an abundant outspreading pubescence ; wings whitish 

 subhyaline with a heavy brown pattern that is irregularly 

 cross-banded, darkest in the costal cells, paler in the caudal 

 cells ; interspaces without dark markings.
