For this interesting species, very remarkable for the shortness 
of the scape of the antenne, I am indebted to Mr. Thwaites of 
Bristol. ‘The specimen had been preserved in spirit, the colours 
are therefore probably somewhat faded, or perhaps altered from 
their original hue. 
P.S.—M. Macquart has also published the following descrip- 
tion of a new species of this genus, nearly allied to C. conopsoides, 
from Algeria. 
Ceria scutellata, Macq. Dipt. Exot. Nouv. tom. ii. part 2, p. 10, 
pl. 1, fig. 1 
Petiolo antennarum elongato, pedibus rufis, femoribus annulo 
fusco, scutello flavo. 
Long 3} lin. ¢. 
** Semblable a la C. conopsoides, excepté une petite bande trans- 
versale noire a la base des antennes au lieu des deux petites 
bandes obliques qui descendent de cette base vers les cétés. 
Front; point de ligne noire qui de la base des antennes 
s’étend jusqu’a la partie linéaire du front. Pétiole des 
antennes brundtre en dessus, fauve en dessous. Thorax; 
point de petite tache jaune en avant de la base des ailes au- 
dessus de la bande jaune des flancs, écusson entiérement 
jaune.” —D’ Alger, Museum du Jardin des Plantes, Paris. 
Note.—This is the only exotic species known to M. Macquart, 
except Wiedemann’s two species, which he does not apBeas to 
have ever seen in nature.
