ICHNEUMONIN^ IN THE BRITISH MUSEUM. 125 



Abdomen elongate-fusiform, deplanate, bright metallic blue, with 

 petiole alone (though to a vai'iable extent) rufescent ; postpetiole 

 broader than long, finely shagreened with deep apical and lateral 

 punctures ; second and third segments closely punctate, former 

 not basally striate, its gastrocoeli large and transverse ; venter 

 plicate throughout ; hypopygium remote from the subexserted, 

 black terebra. Legs stout and somewhat short, brick-red with 

 only the onyches black; hind coxse with stout scopulte. Wings 

 ample and evenly nigrescent, Avith stigma black; areolet trian- 

 gular, coalescent above; nervelet obsolete. Length, 20-22 mm. 

 $ only. — Apparently common in Central East Africa ; many 

 taken at Mlanje during May, June. September, and December, 

 1913; in the Ruo Yalley at 2000 feet in December 1913; and 

 to the S.W. of Lake Chilwa, during January 1914, in Nyasaland ; 

 as well as at Masongaleni at 3000 ft. in March 1911, in British 

 East Africa {Neave) ; and near Chirinda Forest in Gaza Land, 

 during March 1907 {Marshall). 



2. NIGKIPEDALIS, Sp. n. 



Dull, pale ferruginous with the abdomen blue and wings 

 evenly nigrescent ; base of mesopleuras sometimes black-marked. 

 Length, 19-21 mm. S $ ■ — This species is certainly distinct 

 from the last, yet the § differs solely in having the hind legs 

 (except usually their trochanters and disc of coxse) and the inter- 

 mediate tarsi, black ; the flagellum immaculate black and the 

 scutellum pyramidal with its disc acute. The S agrees there- 

 with, but the scutellar disc is subspinately produced, — Entebbe 

 early in September 1911, and on W. shore of the Victoria 

 Nyanza at Buddu at 3700 feet in September 1911, in Uganda ; 

 and at Mlanje, during the first half of June 1913, in Nyasaland.

Cameron, Ann. S. African Museum, v. 1906, p. 165. 



The deeply impressed basal metanotal sulcus places this genus 

 incontrovertibly in the Joppides.

This striking species was originally described from Cape 

 Colony; but it has a wide range. I have recently examined 

 examples of both sexes (Cameron knew only the $ , loc. cit., and 

 I brought forward the S in the Annals of the S. Afr. Mus, 1917) 

 from Bai-berton in the Transvaal, where P. Kendall found it 

 about 1890 (ex coll. Distant) ; from Mlanje on 25th February, 

 1913, in Nyasaland; from the Siroko River near the west foot 

 of Mount Elgon at 3600 feet in mid-August, 1911 ; on the west 

 shore of the Victoria Nyanza at 3700 feet near Buddu during the 

 following Septexnber ; on the Semliki Plains near the south
