Ichneumon puyillator, L. 



Head nearly always distinctly transverse, rarely subcubical ; 

 eyes internally emarginate next the scrobes ; clypeus laterally 

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

 planate face ; mandibles broad, with equal teeth. Antennae 

 subfiliform, not longer than the body, and always somewhat 

 stout ; scape subentire. Thorax always coarsely sculptured dis- 

 cally, scabrous or rugulose ; metathorax elongate and not apically 

 produced: inetanotum usually impressed longitudinally in the 

 centre, rarely carinate, with more or less obsolete arese ; spiracles 

 always elongate and often linear. Scutellum coarsely sculptured 

 and not deplanate. Abdomen strongly compressed throughout 

 and usually centrally red ; first 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 ; terebra very rarely elongate. Legs slender, 

 with the hind femora usually a little stouter ; tibiae obsoletely 

 spinulose ; 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 intercepted below, rarely in, its centre, but sometimes simply 

 a little curved at its lower extremity. 



Range. Palsearctic and Nearctie Begions, 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. 1 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 northern forms may prove to be 

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

 names to stand provisionally until a more exhaustive comparison 

 with the European forms is possible. 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. speciosus, the type of which I have had 

 no opportunity of examining.
