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



includes 13*6 mm. ; wing 12 mm. ; hind leg, femur 9 mm., 

 tibia ll'-l mm. 



Rostrum and palpi dark brown. Antennae dark brown, 

 the base of the elongate first scapal segment sparsely golden- 

 pollinose ; second scapal segment obliquely subglobular ; 

 three basal flagellar segments united into a stout fusion- 

 segment, the suture between the second and third weakly 

 indicated ; remaining flagellar segments gradually becoming 

 longer and narrower outwardly ; verticils rather short. 

 Anterior part of the vertex densely golden-pollinose ; 

 between the eyes at the narrowest point a broad velvety- 

 black band enclosing an oval golden median area j 

 remainder of the vertex black, sparsely golden-pollinose ; 

 vertex with a small raised median area. 



Pronotum rather conspicuous, shiny chestnut-brown, 

 Mesonotal prsescutum reddish brown with two narrow, 

 indistinct, brown stripes, one on either side of the pale 

 median line ; remainder of the mesonotum reddish. Pleura 

 shiny reddish brown, darker brown on the dorsal edge of 

 the mesepisternum and on the mesepimeron, the latter 

 silvery-pruiuose. Halteres pale brown, the knobs darker 

 brown. Legs with the coxae reddish brown, the fore coxae 

 darker ; trochanters reddish brown ; femora dull yellow, 

 the tips narrowly dark brownish black ; tibiae dark brown, 

 the tips narrowly brownish black ; tarsi dark brown. 

 Wings dull grey, the costal region more yellowish, this 

 colour including cells C, Sc, and 2nd 1\\ ; outer end of cell 

 R 2 more infuscated ; costal cell with a series of about ten or 

 eleven cross-veins and spurs extending from costa, these 

 conspicuously seamed with brown ; dark brown spots at the 

 ends of veins Sc lt R u and R 2 ; paler brown seams at the 

 origin of Rs, along the cord, outer end of cell 1st M 2 , and 

 the fork of M 1+2 ; indistinct seams along veins Maud 2nd A, 

 and more distinctly along Cu ; veins dark brown ; those in 

 the costal region more yellowish. Venation : Sc x and ti x 

 ending rather close together at the wing-margin as in the 

 genus ; Rs strongly augulated at origin and here sending a 

 broken cross-vein to vein M as in C. multistriatus End. ; 

 7? 2 +3 shorter than the deflection of R A+b ; R 2 almost per- 

 pendicular at origin, r inserted at the bend ; R x beyond r 

 about equal to the basal deflection of 0% ; vein R 3 bent 

 strongly towards R i+5 near its tip, so cell R 2 is nearly as 

 wide at the margin as cell 2nd R x ; r-m nearly as long 

 as the deflection of R 4+5 ; cell Is* M 2 rather small, the 

 inner end not conspicuously produced and pointed ; cell M x
