244 insecta. 



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 Avhcre the maxillae and labium are much shorter, 

 and, at most, flexed at the extremity, are comprised by Latreille in 

 the genera Sphex, PronjEus, Chlorion. In 



Pron^us, Lai., 

 As in Ammophilus, the second cubital cell receives the two recur- 

 rent nervures t- 



Sphex, /)roper. 

 That cell only receives the first ; the third is inserted under the 

 other \. In 



Chlorion, Lat., 

 The first recurrent nervvire 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 

 larvae 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 



DoLiCHURus, Lat. || 

 The last Fossores of this third division have no dentations in the 

 mandibles, and are comprised in the genera Pelopseus, Podium, and 

 Ampulex. These organs are striated. 



Ampulex, Jur. 



Similar to Chlorion in the insertion of the recurrent nervure of 

 the superior wings ^. 



In the two other subgenera, the second cubital cell receives these 

 two nervures. The clypeus is usually dentated.

 Where the antennae are inserted beneath the middle of tlie anterior

§ Ibid., 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 Oricntales. 



II Lat., Ibid., 57, 387 ; each of the second and third cubital cells receives a re- 

 current nervure.
