52 POMPILID®. 
This species I have found at Highgate conveying a small 
sandy coloured larve; it does not appear so early as P. 
viaticus, being seldom to be found before the summer solstice. 
Mr. Walker has taken it in the Isle of Wight, and at Bar- 
mouth, in September.

Entirely black: head delicately punctured ; the clypeus with a 
few rufescent sete, as well as the exterior of the mandibles, their 
apex testaceous; labrum concealed. 
Thorax punctured ; metathorax gibbous, scarcely perceptibly 
punctured and shining, having sometimes a small variole at the 
centre of its base; the superior wings with their nervures pitchy, 
a narrow dark transverse fascia covering the transverso-medial 
nervure and the geniculation of the interno-medial, another, 
much wider, traversing the wing at the marginal and submarginal 
cells, which it nearly occupies, and a narrow dark edge at the 
apex of the wing in some specimens, leaving between it and the 
second fascia a milky spot; the legs without the cilia to the 
anterior tarsi, and the posterior tibize quite smooth, or having 
only a few lateral short hairs. 
The abdomen with the last segment covered with longish hair, 
and the apex slightly rufescent ¢. 
The ¢g differs in having the fascize of the wings less distinctly 
marked.
