130 INSECTA. 
LXV, 16. Deep black; abdomen red, intersected with black 
circles. 
The second family of the genus Misque of Jurine is composed of 
true Pompili, but in which the third cubital cell is small and petio- 
late(1). 
That of Salius, Fabricius, was established on the males of certain 
species in which the prothorax and metathorax are proportionally 
longer than those of the Pompili, and the mandibles present no den- 
tations(2). 
Prianicers, Lat., Van der Lind. 
Closely allied to Salius in the general form of the body; but the 
head is flat and its posterior margin concave, its ocelli are very 
small and distant, and the eyes elongated and occupying its sides. 
The antennz are inserted near the anterior margin. The two ante- 
rior legs are distant from the others, short, curved underneath, and 
have large coxz and thighs. There are but two complete cubital 
cells in the upper wings, the second of which receives the first re- 
current nervure; the incomplete or terminal cell receives the other 
nervure at a short distance from its junction with the second cell. 
A second species, besides the one on which this subgenus was 
founded(3), has been discovered in Brazil by M. de la Cordaire, 
who was kind enough to give it to me, and whose name it will 
bear. In

There are also but two complete cubital cells; but the second re- 
ceives the two recurrent nervures. The Apori, in all else, resemble 
the true Pompili(4). 
In the others the first segment of the thorax is narrowed before in 
the form of a joint or knot, and the first ring of the abdomen, some- 
times even a part of the second, is narrowed into an elongated pe- 
dicle. Their superior wings always present three complete cubital 
cells and the commencement of a fourth. 
Those in which the mandibles are dentated, the palpi filiform and
