EXOCIIILUM. 411 



fulvous, with the second, fifth and sixth segments discally black- 

 lined, and the third to sixth laterally broadly black. Legs red, 

 with the anterior paler and subflavidous ; posterior coxae except 

 basally, and the apices of both the hind femora and tibiae, black 

 Wings unicolorous int'umate-fulvous ; stigma and costa fulvous ; 

 nervures infuscate. 



Length 17-22 millirn. 



PUNJAB : Simla, 7000 ft., v. 97, x. 07 (Col. Nurse, H. M. Lefroy) ; 

 UNITED PROVINCES : Mussoori (Rotlmey) : ASSAM : Shilloiig, 

 6000 ft., iv. 03 (Roivland Turner). EUROPE. 



The stout conformation, flavous scutellum, and conspicuously 

 black apices of both the hind tibiae and femora, render this hand- 

 some species easily recognised. 



Eatzeburg has traced the life-history of this species from the 

 egg in his ' Die Ichneumonen ' (i, pp. 80-87 ; cf. pi. ix, figs. 11-22), 

 and this ma} 7 well be consulted as a typical account of the deve- 

 lopment of IOHBBDMOFIDJB. 



There is a male in Col. Nurse's collection which Cameron had 

 named A. mussouriense. This circumstance has enabled me to 

 synonymise the latter's species with the Palaearctic variety 

 giganteum, Grav., as brought forward by Eatzeburg and "Wesmael. 

 The typical form of E. circumflexum is common throughout 

 Europe, but this variety, which averages larger and extends to 

 30 millirn. in length, occurs principally in the south. It prey. 8 

 upon the larvae of large Bombycid moths. 



303. Exochilum orbitale, Mori. 



E.vochilum orbitale, Moiiey, Rev. Ichn. Brit. Mas. ii, 1913, p. 78. 



c? 5 . A red species with the head and thorax, excepting the 

 flavous mouth, face, frontal and very broad external orbits, tegulae 

 and scutellum, black ; head not posteriorly buccate, antennae 

 slender and elongate. 



Length 22 millim. 



BUEMA : Karen Hills, 3000-3700 ft. (L. Fea). 



Type in the Genoa Museum. 



This is too closely allied to the last species to need a detailed 

 description ; therefrom it differs in its more slender and elongate 

 form, legs and antenna?, the posteriorly narrower head, with its 

 conspicuous flavous external and vertical orbits, the entirely pale 

 frontal cristula and scape, deplanate scutellum, and immaculate 

 red hind femora and coxae. 



I associate the male with some degree of doubt ; the sculpture 

 and all essential points are analogous, but the external orbits are 

 pale only below, and both the frontal cristula and scutellum are 

 immaculate black ; however, I greatly dislike erecting new species 

 on unsatisfactory evidence, and the only male I have yet seen is 

 a broken example from Shillong, Assam, GOOO ft., ix. 03 (Roivland 

 Turner).
