includes 13'6 mm, ; ^Ying 12 mm. ; hind leg, femur 9 mm., 

 tibia ll'-i mm. 



Rostrum and palpi dark brown. Aiitennse dark brown, 

 the l^ase of the elongate first sca[)al segment sparsely golden- 

 pollinose ; second scapal segment obliquely subglobular ; 

 three basal fl;igellar 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-poUinose ; 

 between the eyes at the narrowest point a broad velvety- 

 black band enclosing an oval golden median area ; 

 remainder of the vertex black, sparsely golden-pollinose ; 

 vertex with a small raised median area. 



Pronotum rather conspicuous, shiny chestnut-brown. 

 Mesonotal prfescutum reddish brown with two narrow, 

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

 median line ; lemainder of the mesonotuni reddish. Pleura 

 shiny reddish brown, darker brown on the dorsal edge of 

 the mesepisternum and on the mesepimeron, the latter 

 silvery-pruinose. Halteres pale brown, the knobs darker 

 brown. Legs with the coxae reddish l)rown, the fore coxae 

 darker : trochanters reddish brown ; femora dull yellow, 

 the tips narrowly dark brownish black ; tibiae dark Ijrowu, 

 the tips narrowly brownish black ; tarsi dark brown. 

 Wings dull grey, the costal region more yellowish, this 

 colour including cells C, Sc, and 2ncl R^ ; outer end of cell 

 R2 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 Sci, Ri, and R2; paler brown seams at the 

 origin of Rs, along the cord, outer end of cell Jst M2, and 

 the forkof ilij^g ; indistinct seams along veins ikf and 27id A, 

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

 the costal region moi'e yellowish. Venation : Sci and L\ 

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

 genus; Rs strongly angulated at origin and here sending a 

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

 i?2+3 shorter than the deflection of R^j^r, ; R2 almost per- 

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

 about equal to the basal deflection of Cui ; vein R^ bent 

 strongly towards Ri^-^ near its tip, so cell R.2 is nearly as 

 Avide at the margin as cell 2n(l R^ ; r-?/i nearly as long 

 as the deflection of ii'4+5 ; cell 1st il/g I'ather small, the 

 inner end not conspicuously produced and pointed ; cell Afj
