surface of postalar calli, with a narrower border of similar hairs, more closely set 

 and sometimes also somewhat paler than in front ; depth of hind border little 

 more than half that of fore border ; on each side of dorsum, occupying 

 presutural depression immediately in front of outer end of transverse suture, is a

 a little way along transverse suture ; remainder of main portion of dorsum 

 moderately shining, and clothed with appressed black hairs ; scutellum dull black, 

 clothed with appressed black hairs, and with its upper surface minutely granular ; 

 pleurae and pectus clothed with black hair, except that there is an oblique stripe

 dorsum of first segment, which is dull black ; dorsum, except hind border of 

 second segment, clothed with minute, appressed, black hairs ; band of silvery-

 depth in different specimens), but not quite reaching lateral margins ; ventral 

 scute of second (visible) segment with a large patch of shining silvery- white 

 hairs on each side, towards hind margin ; ventral scute of fourth segment with a 

 few yellowish hairs on each side. Wings : discal and certain other cells sometimes 

 each with a paler streak in centre ; first posterior cell either narrowly open or 

 else closed on wing-margin, in some specimens closed in one wing and open in the 

 other. Squamae dull waxen-white. Halteres dark brown, tips of knobs 

 ochraceous-buff. Legs : coxae black and clothed with black hairs ; femora,

Cadicera flavicoma, sp. n. 



Q.— Length (1 specimen) 15*5 mm. ; width of head 5 mm. ; width of front at 

 vertex just under 1 mm. ; length of proboscis 3*5 mm. ; length of wing 15 mm. 



Front and face cinnamon-rufous; antennae ferruginous ; terminal joint of palpi 

 orange-rufous ; body black or clove-brown, marked with patches of bright Naples- 

 yellow pile ; last two segments of abdomen cinnamon-rufous or orange-rufous, hind 

 borders of other abdominal segments {more or less distinctly) cinnamon-rufous ; wings

 Ric, in general appearance, but distinguishable at once by the front and face not
