Mr. W. W. Saunders on Ceria. 67 
XII. Description of an additional Species of Ceria. 
By W. W. Saunvers, Esq., F.L.S., &e. 
[Read 7th August, 1843.] 
Art a recent meeting I laid before this Society descriptions of 
several new species of the interesting Dipterous genus Ceria. To 
the paper which was then read I beg now to add another fine spe- 
cies which I have detected in the rich entomological collection of 
the Rev. F. W. Hope, after whom I take the liberty of naming 
it. This species will range in the division with the first joint of 
the abdomen much attenuated, and next to Ceria Gambiana, 
W. W.S., adding one more species to the African group of this 
genus. 
Ceria Hopei, W. W. Saund. (Plate IV. fig. 6.) 
Head yellow with the vertex, a broad line down the centre of 
the face, and two lateral patches just beneath the eyes, dark 
chesnut. Antenne and pedicle of the same colour. Eyes black- 
brown. Thorax dark chesnut, with a broad longitudinal yellow 
band on each side, extending from the base of each wing to the 
anterior margin, and another broad band of the same colour 
reaching downwards from a little before the base of each wing. 
Scutellum yellow. Abdomen with the first joint much attenuated, 
long, of a dark chesnut, becoming nearly black towards the base, 
on each side of which there are two yellow lobes ; second, third and 
fourth joints black-brown, with an ashy tint. Wings sandy, with 
a broad rufous brown band along the anterior margin, growing 
blackish towards the apex. Legs dark chesnut, with the tarsi 
somewhat darker. 
Length seven-tenths inch, expan. 1 inch and 3-tenths. 
Inhabits Sierra Leone. 
In the Cabinet of the Rev. F. W. Hope. 
This species is nearly allied to C. Gambiana, but a marked 
difference exists in the three terminal joints of the abdomen being 
concolorous.
