Order Hymenoptera. Fam. Ichneumonidas. 



Type of the Genus, Banchus pictus Fab. 

 Banchus Fab., Panz., Grav., Curt. — Ichneumon Linn., Fab. 



Antennae inserted near the middle of the face, as long as the 

 body in the female, shorter and more curved at the apex in the 

 male ; setaceous, composed of numerous joints, basal one robust 

 and ovate, truncated obliquely to receive the •2nd, which is stout, 

 3rd small, 4th the longest, the remainder decreasing in length 

 and size to the apex : (1, the base and apex). 

 Labrum triangular and hairy, the base horny, with a membra- 

 nous attenuated and pointed lobe attached beneath (2). 

 Mandibles curved, bifid at the apex, internal tooth the longest 

 and emarginate (3). 



MaxillcE terminated by an orbicular hairy lobe, with a smaller 

 one on the inside. Palpi not very long, pubescent and com- 

 posed of 5 joints, nearly equal in length, 2 basal joints stout 

 and clavate, 1st rather the longest, 3rd slender, 4th spatulate 

 and very much dilated in some species, 5th slender and linear 



(4)- 



Mentum oval, anterior angles emarginate to receive the Palpi, 

 which are not very short; hairy and 4-jointed; 2 basal joints 

 short and pyriform-truncate, 3rd not quite so stout, a little 

 longer and truncated obliquely, 4th the longest, slender and 

 linear. Lip semicylindric, slightly emarginate (5). 

 Head short transverse, face orbicular : eyes vertical, ovate : ocelli 

 large, 3 in triangle on the crown. Thorax gibbose, ovate (T, c the 

 collar) : scutellum, convex, trigonate-ovate, generally with an in- 

 curved spine towards the apex (s). Abdomen sessile, subftisiform, 

 compressed beneath and at the apex, somewhat scimeter-shaped in 

 profile, basal joint broad and transverse at the base (6, the same in 

 profile), the back most curved in the male, the belly more so in the 

 female ; ovipositor not exserted. Wings with a large submarginal 

 cell, the lower external nervure not angulated, areolet subtrigonate, 

 the base convex. Legs, hinder pair long and stout, with large coxce :

Nothing, I believe, is known of the oeconomy of these insects : 

 the males are distinguished by short antennae, spiral at the 

 apex; the abdomen is generally less dilated vertically at the 

 apex, and is often a little incurved.
