300 BRITISH ICHNEUMONS. lExetastes. 



in July (Charbonnicr) ; Alderney (Luff) ; common at Shere, in Surrey 

 (Capron) ; in Lyndhurst garden, in July (Adams) ; Ripple, near Dover, in 

 August (Sladen) ; Guestling, near Hastings (Bloomfield) ; Felden, in 

 Herts (Piffard) ; Bovey Tracey, in De\'on, in August (Hamm) ; Kings 

 Lynn (Atmore) ; Eastbourne (Nurse) ; Arousehold Heath, Norwich 

 (Bridgman) ; Bungay and Tostock, in Suffolk, in autumn (Tuck). It is 

 usually found in August on the flower-tables of Angelica sylvcstris and 

 Heracleiim sphondylium, though sometimes swept from the herbage in 

 woods. I have taken it in the Bentley Woods, near Ipswich, in 1894; in 

 the Havenstreet Woods, in the Isle of Wight, at the end of June, 1907 ; 

 and on flowers in Finborough Park, near Stowmarket and at Lyndhurst, 

 in the New Poorest, in August. It does not appear to have been bred in 

 Britain, though on the Continent it has been raised by Snellen in Holland 

 from Noctiia Alsincs, and in France by Dr. Giraud from Toxocampa 

 pastinum.

Exetastes femorator, Desv. Cat. 94, <? ? ; Holmgr. Sv. Ak. Handl. 1858, n. 8, 

 p. 152 ; Voll. Pinac. pi. xvii, fig. 6 ; Thorns. O.E. xxii. 2415, ? . 



A black, shining and punctulate species with the abdomen centrally 

 broadly red and the nervelet elongate. Head punctate, a little broader 

 than the thorax and somewhat narrowed behind the eyes ; clypeus de- 

 planate and apically rounded ; mouth produced. Antennae setaceous and 

 longer than half the body; immaculate. Thorax stout, gibbulous and 

 punctate ; metathorax with the upper areae strongly incomplete. Scutellum 

 black. Abdomen glabrous and nitidulous," longer than the head and 

 thorax, and apically compressed ; red with the basal half of the first seg- 

 ment, apex of the fourth and whole of the remainder, black ; basal seg- 

 ment slightly curved and subdilated towards the apex ; the second and 

 third subequal in length ; venter of 9 rufo-testaceous, with the apical 

 segments produced and somewhat compressed ; terebra two-thirds the 

 length of the basal segment. Legs black or nigrescent ; anterior slender, 

 of $ with the base of their tibiae and apices of the front femora paler, 

 of $ with the tibiae and tarsi red ; hind ones not slender with their 

 femora, except apically above, sanguineous. Wings infuscate Mith the 

 ner\elet extending nearly to the centre of the first cubital cell ; stigma 

 fulvescent or piceous, and tegulae black. Length, 8 — 10 mm. 



This species is said to be at once recognised by having the second and 

 third segments entirely, the first broadly at the apex, the base of the 

 fourth, and nearly the whole of the hind femora, red ; the anterior femora 

 apically, and the front tibiae in front, rufescent ; and by the basally 

 serrate claws which extend beyond the pulvilli.
