~ The following paper is the result of the study of material recently received by 
the Entomological Research Committee, by which the types of two of the species 
described below have been presented to the British Museum (Natural History) : 
the type of Chrysops centurionis has been handed over to the National Collection 
by its discoverer, Captain A. D. Fraser, R.A.M.C. 
Genus Curysops, Meigen. 
Chrysops magnifica, sp. n. (fig. 1). 
O—Length (5 specimens) 6°75 to 9 mm.; width of head 2°5 to 3 mm. ; 
width of front at vertex 1 mm. to just over 1 mm.; length of wing 7 to 8°5 mm. | 
General coloration of dorsal surface of head and body chrome-yellow, saffron- 
yellow or cadmium-yellow,* with dark markings as shown in fig. \—Head saffron- 
yellow or chrome-yellow, frontal callus and facial tubercle shining black, ocellar spot 
dull clove-brown ; antenne black, first joint not swollen ; thorax black, dorsum on each 
side of middle line with a lateral and an admedian saffron-yellow or chrome-yellow, 
pollinose, longitudinal stripe, the yellow stripes on each side of the middle line confluent 
in front and behind ; dorsum of abdomen cadmium-yellow or saffron-yellow, with a 
pair of black, longitudinal stripes, each composed, as shown in fig. 1, of a series of 
elongate blotches somewhat irregular in outline ; wing-markings as shown in fig. 1 ; 
legs in normal specimens entirely black, except bases of first joints of middle and 
hind tarsi, which are faintly tinged with cinnamon. 
Head (except on ocellar spot, frontal callus, and facial tubercle) clothed with 
short, saffron-yellow or cadmium-yellow hair ; frontal callus nearly twice as wide 
as deep ; face with a single, median, facial tubercle, showing no trace of a division 
except (in certain specimens) a slight indentation in the centre of its upper margin ; 
palpi greyish clove-brown or blackish, clothed on outer surface with chrome- 
yellow or saffron-yellow hair, terminal joint large, lanceolate ; antenne moderately 
stout, but first jot not incrassate and second joint not short, first and second 
joints clothed with short black hairs, which, on the inner and upper sides 
of the first joint are occasionally mixed with saffron-yellow hairs. Thorax: 
pleure each with a broad, saffron-yellow or chrome-yellow, pollinose stripe, 
including humeral callus on each side and running below root of wing to 
base of halter ; a second and shorter stripe below the one just mentioned, and 
between imide coxa and root of wing ; pectus partly covered with Seger elles 
or saffron-yellow pollen; scutellum saffron-yellow or chrome-yellow pollinose, 
clothed, like the saffron-yellow or chrome-yellow thoracic stripes already described,
