HYMENOPTERA. 131 
almost equal, the maxille and ligula very long, in the form of a 
proboscis and bent underneath, and in which the second cubital cell 
receives the two recurrent nervures, have been separated from them 
by M. Kirby under the generic name of | 
AmmMopuHiLus, Kirby. 
To this division belongs the 
A. subulosus; Sphex subulosa, L.; Panz., Faun. Insect. Germ., 
LXV, 12. Black; abdomen bluish-black, narrowed at base into 
a long, slender, and almost conical pedicle, the second ring, its 
base excepted, and the third, fulvous; a silvery and silken down 
on the front of the head in the male. 
The female, with her feet, excavates a deep hole in the 
ground along the borders of roads, in which she deposits a 
caterpillar, killed or mortally wounded by her sting, laying an 
egg by the side of it; she then closes the hole with grains of 
sand, or even a small pebble. It would appear that she repeats 
the operation several times in succession in a similar manner, 
in the same nest. 
A. arenarius; Pepsis arenaria, Fab.; Panz., Ibid., LXV, 13, is 
also an Ammophilus. Black and hairy; pedicle of the abdomen 
abruptly formed by its first ring, the second, third, and base of 
the fourth, red. 
In some—the first family of Miscus, Jur.—the third cubital cell is 
petiolate superiorly(1). 
Those species in which the mandibles and palpi still preserve a 
similar form, but where the maxillz and labium are much shorter, 
and, at most, flexed at the extremity, are comprised by Latreille in 
the genera SpHEx, PRonazus, Cutorion. In 
Pronzvus, Lat. 
As in Ammophilus, the second cubital cell receives the two recur- 
rent nervures(2). 
SPHEX, proper. 
That cell only receives the first; the third is inserted under the 
other(3). In
