is also an Ammophilus. Black and hairy; pedicle of the abdo- 
men 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 *. 
Those species in which the mandibles and palpi still preserve a 
similar form, but where the maxille and labium are much shorter, 
and, at most, flexed at the extremity, are comprised by Latreille in 
the genera SpHEx, Pronmus, Cutorion. In 
Pronazus, Lai., 
As in Ammophilus, the second cubital cell receives the two recur- 
rent nervures ft. 
SPHEX, proper. 
That cell only receives the first; the third is inserted under the 
other}. In 
Cutorion, Lat., 
The first recurrent nervure is inserted under the first cubital cell, 
and the second under the third. ‘ 
C. Compressum, Fab. Very common in the Isle of France, 
where it wages war against the Kakerlacs, provisioning its 
larvee with their bodies. It is green; the four posterior thighs 
red. 
C.lobatum. Entirely of a golden-green. In Bengal § 
Other species, in which the mandibles are still dentated, but where 
the maxillary palpi are much longer than those of the labium, and al- 
most setiform, compose the genus 
Douicuurvs, Lat. || 
The last Fossores of this third division have no dentations in the 
mandibles, and are comprised in the genera Pelopzeus, Podium, and 
Ampulex. These organs are striated. 
AMPULEX, Jur. 
Similar to Chlorion in the insertion of the recurrent nervure of 
the superior wings 4. 
Im the two other subgenera, the second cubital cell receives these 
two nervures. The clypeus is usually dentated.

§ ipid., p- 57. In this species, the first recurrent nervure is insulated at the junc- 
tion of the first cubital cell with the second. For the habits of the C. compressum, 
Fab., see Sonnerat, Voy. aux Indes Orientales. 
|| Lat., Ibid., 57, 387; each of the second and third cubital cells receives a ree
