Genotype, Ichneumon pugillator, L. 



Head nearly always distinctly transverse, rarely subcubical ; 

 ■eyes internally emargiiiate next the scrobes ; clypeus laterally 

 foveate, and not discrete from the closely punctate and subde- 

 l^lanate face; mandibles broad, with equal teeth. Antenna 

 subfiliform, not longer than the body, and always somewhat 

 stout ; scape subentire. Thorax always coarselv sculptured dis- 

 cally, scabrous or rugulose ; inetathorax elongate and not apically 

 produced; metanotum usually impressed longitudinally in the 

 centre, rarely carinate, with more or less obsolete arege ;* spiracles 

 always elongate and often linear. Scutellum coarsely sculptured 

 and not deplanate. Abdomen strongly compressed throughout 

 and usually centrally red ; iirst segment not plicate beyond the 

 centre of the postpetiole; the two basal segments narrow, with 

 their spiracles beyond, very rarely in, their centre ; third at least 

 basally margined; tei-ebra very rarely elongate. Legs slender, 

 with the hind femora usually a little stouter ; tibia? obsoletelv 

 spiuulose; tarsi not dilated, and their claws always more or less 

 closely pectinate ; calcaria stout, with the front ones sinuate. 

 Areolet large, broad, always triangular and distinct, often petio- 

 late and never broadly sessile : stigma narrow ; radial cell not 

 broad, with the external radius usually bisinuate ; lower wing 

 with the basal abscissa of the radius and the recurrent nervure 

 strong and of variable relative length ; nervellus usually geniculate 

 or intercei)ted below, rarely in, its centre, but sometimes simply 

 a little cur\ed at its lower extremity. 



Bmir/e. PaL-earctic and Xearctic Eegioiis, India, Ceylon. 



With us this genus, easily recognised by its elongate meta- 

 thoracic spiracles and large triangular areolet, is almost confined 

 to the hill districts, and the very great majority are only known 

 from the Himalayas ; the mountains of Ceylon have five' species, 

 and both Poona and Calcutta but one. I regret that my know- 

 ledge of the European representatives is insufficient to enable me 

 to clear up all the synonymy ; but I have little hesitation in 

 saying that most of at least the nortlierii forms may prove to be 

 widespread Pahiearctic species; but it is better to allow Cameron's 

 names to stand provisionally until a more exhaustive comparison 

 with the European forms is ])os3ible. Cameron's descriptions are 

 somewhat superficial, and omit many of the more important 

 characters utilised by Holmgren and Forster to such an extent 

 that I cannot place his C. s/ieciosus, the type of which I have had 

 no opportunity of examining.
