Very like the preceding, from which it may be known by its truncate 

 clypeus and flavous markings, as well as by the following points. Head 

 concave behind the eyes; facial, genal, and vertical orbits broadly fulvous, 

 often entirely black in c? ; clypeus apically truncate; mandibles rufescent 

 throughout in ? , at base in 6 , distinctly bidentate ; joints of maxillary palpi 

 sub-cylindrical. Antennae of? with joints 11-15 stramineous; usually red 

 beneath in $. Thorax black in ? ; c? with pronotum, lines before and 

 beneath radix, and two distinct dots before scutellum, flavous; areola 

 represented by a tubercle, posterior area with strong lateral costae. 

 Scutellum finely punctate, black, its posterior face stramineous; acuminately 

 arcuate. Abdomen black; c^ with metallic violet reflection; the petiole 

 not usually explanate apically; its central area aciculate in both sexes; 

 gastrocaeli broad and deeply impressed; terebra slightly exserted beyond 

 pygidium. Legs bright fulvous, coxae and trochanters almost entirely 

 black ; anterior femora and tibiae infuscate above ; the ? has all the tarsi 

 entirely fulvous. Wings sub-hyaline, with a slightly darker apical fascia ; 

 all the nervures piceous ; areolet sub-deltoid, not petiolate. Length, 

 10-14 n^™- 



The $ above described differs from the type form in the immaculate 

 scape, mesopleurae, coxae and trochanters, and in having the hind femora, 

 tibiae and tarsi unicolorous. 



A single female was bred from a pupa oi Apatura Iris on July 12th, 1901, 

 by Mr. J. F. Musham; the larva was taken in the New Forest. The 

 parasite emerged through a " circular hole one-eighth inch diameter in the 

 upper left half of the thorax, not quite in the centre ; the pupa was only 

 slightly discoloured, much less so than when the host emerges. The larva 

 before pupation was very small and sluggish, and its right process was only 

 half as long as the left; oviposition of the parasite took place in tlie 

 autumn, before hibernation, when the larva was in its earliest stages."

It is very rare on the continent ; M. I'Abbe Berthoumieu records it 

 only from Hungary ; Tischbein bred it from the above host. 



3. spinosus, sp. n. 



Smaller and more finely sculptured than the preceding. Head somewhat 

 coarsely but not deeply punctate, black, strongly narrowed behind the eyes ; 

 frons deplanate, with large glabrous scrobes ; cheeks longer than base of 

 mandibles ; face not protuberant, pilose ; clypeus elongate, slightly convex, 

 apically truncate and indistinctly discreted from the face ; labrum strongly 

 exserted ; mandibles small and inconspicuous ; palpi testaceous ; facial 

 orbits broadly, and frontal narrowly, flavous. Antennae long, setaceous, 

 sub-nodulose towards the attenuate apices ; black, ferrugineous beneath ; 

 seventh flagellar joint quadrate. Thorax finely punctate ; black, witli whitish 

 pubescence ; pronotum laterally, and a small callosity beneath the radix, 

 indistinctly flavidous ; notauli and sternauli distinct, though small ; metano- 

 tum rugose, sub-regularly transcostate below the large and acute apophyses ;
