exserted, promin., rarely very short; areolet of fr.-w. pentag. or 
small quadr., often incompl. or wanting; apt. a. subapter. forms 
common. Subf. II. Cryptinae, 
Abd. usually depress. a. sess., never strongly compress., although sometimes 
compress. tow. apex. more rarely petiol., spir. of 1.sgm. placed at 
or a little before the middle, rarely slightly behind the middle. 
Abd. elong., subeylindr., most frequently sess,, rarely petiol. or sub- 
compressed at apex; ovipos. always promin., often very long; 
areolet in front wings, when present, usually rhomboid. or triang. 
very rarely pentag. Subf. III. Pimplinae. 
Abd. not, or rarely, very long, depress. and sess., fusif., clavate, ovate, 
or oval, more rarely distinetly petiol.; ovipos. hidden, never promin. 
at the most subexs.; areolet triang., rhomboid. or wanting, rarely 
pentag. Subf. IV Tryphoninae. 
Abd. usually long, wholly compress. or compress. along the post. half, 
rarely subeylindr.; in the latter case the petiole is somewhat 
abruptly dilated at apex; spir. of 1st sgm. most frequently plaved 
at or behind the middle, more rarely before; areolet in fr.-w. usually 
triang., rhomb. or wanting, often petiol.; ovip. either hidden or 
prominent Subfam. V Ophioninae. 
Subfam. I. Ichneumoninae. 
Hierher die Förster'schen Fam. Trogoidae (= Joppinae Kriechb.), Ichneu- 
monoidae, Listrodromoidae, Alomyoidae u. Phaeogenoidae, A. behandelt sie als 
Tribus, da sie kleine natürl. Gruppen bilden. 
Uebersicht über die Tribus: 
Metathoracic spiracles round or eire., more rarely broadly oval; claws 
simple, never pectinate. 3. 
Metath. spir. linear or long-oval, but very rarely rounded, if round. the 
claws are always pect. 
Mandibles not bident., simple, edent., acute at apex 2. 
Mandibles bident., head not broad. than long, 
Metanot. with a strong constriet. or furrow betw. it a. the postscut., the 
metan. usually short, with a med. elevat. toward base a. without the bas. or 
1st. med. area, or, if at all pres. open; areola often reduced to a tubercle, or if 
defined usually confluent with the petiol. area rarely distinet, horse-hoof shaped 
or broadly transv.: scutell. variable, frequently cone-shaped, pyram. or highly 
convex rarely very flat: sutures betw. the abd. sgmts. often strongly constrict.; 
areolet in front-w. tetrag., triang., or pentag. (rarely wanting). 
Tribus I. Jeppini. 
Metan. without such a constr. or furr., at most with only a weak furr. 
betw. it a. the postscut.; metan. rarely short always without a med. elev. at 
base a. with the bas. or 1st. med. are a distinet, usually complete, the 
areola a. petiolar are separeted, distinct, abd. norm. not or rarely strongly con- 
striet. betw. the sgmts. areol. in front w. pentag. 
Claws simple; 2nd a 3rd abd. sgm. with lunulae. 
Tribus I. Ichneumonini. 
Claws pectin.; 2nd a. 3rd abd. segm. most frequently without lun. or at 
least not present on both sgmts. Tribus III. Listrodromini,
