Order Hymenoptera. Fam. Ichneumonidae. 



Type of the Genus, Leiophron pallipes Curt. 

 Leiophron Nees, Curt., Hal. — Cryptus Fab. 



Antennce inserted in front of the face, as long as the wings in 

 the male, and composed of from 26 to 17 joints ; shorter in the 

 female, and composed of from 21 to 16 joints, filiform and pu- 

 bescent, basal joint the stoutest, 2nd globose, 3rd slender, longer 

 than any of the following, which decrease in length until they 

 become nearly cup-shaped, the apical joint ovate-conic (1). 

 Labrum transverse-oval, with a membranous ciliated margin and 

 an elongate-trigonate pubescent lobe in the middle (2). 

 Mandibles curved, slender, cleft at the apex, slightly pilose ex- 

 ternally (3). 



Maxillee terminated by a rounded hairy lobe with a minute one 

 on the inside. Palpi long pilose and 5-jointed, 1st 3rd and 5th 

 joints the longest, 2nd the broadest, very pilose, 4th the shortest, 

 5 th slender subfusiform (4). 



Mentum oblong, rounded at the base, truncated before. Lip 

 short pubescent subcordate. Palpi as long as the mentum, pi- 

 lose, triarticulate ; basal joint slightly clavate, 2nd subovate, 3rd 

 a little longer subfusiform (5). 

 Head subglobose, transverse. Eyes large and lateral. Ocelli 3, large 

 and prominent on the crown of the head. Thorax elongate-ovate ; 

 neck narrowed: scuteUum semiorbicular. Abdomen ovate-conic,

Apicalis Curt. Guide, Gen. 549. 7. 



In the Cabinets of Mr. Walker, Mr. Haliday and the Author. 



This genus was established by Nees von Esenbeck, who placed 

 it between Perilitus (which follows Aphidius) and Bracon; and 

 Mr. Haliday, in his learned Essay on the Parasitic Hymeno- 

 ptera, locates it between the same groups. Our Leiophrons 

 are easily distinguished from the other IcJmeumones minuti, by 

 the extremely short and sublunar marginal cell, although they 

 are undoubtedly closely allied to the Braconidae.
