On some South African Iclmeumonidae. 



STENARAEUS (MESOSTENUS) LISSONOTUS, Cam., var. NIGRIPES, 



var. u. 



$ . A very slender and strongly elongate black species, with the 

 thorax and ? basal segment brick -red ; the labruin or in $ whole 

 front of head aud the frontal orbits, anus, apices of second and in ? 

 first segments narrowly, and centre of flagellum and hind tarsi broadly, 

 white, as in $ also are the anterior legs, hind trochanters and the 

 petiolar nietathoracic area ; terebra much longer than whole body. 

 Head strongly nitidulous with face dull aud clypeus glabrous, its apex 

 reflexed aud centrally depressed. Antennae nearly as long as body ; 

 basal joints strongly elongate and, in ? , apically subnodulose. Thorax 

 very finely and closely punctate, mesonotum glittering and subglabrous 

 with deep and creuulate notauli ; metathorax elongate, gradually 

 declivous throughout and apically a little produced between the coxae ; 

 basal carina, entire ; basal area and apophyses wanting, spiracles 

 elongate, petiolar area trans-strigose. Scutellum shining, sparsely 

 punctate aud not margined. Abdomen dull with basal segment linear 

 and shining throughout, sulcate, black and sparsely punctate before its 

 white apex ; terebra apically a little renexed, five-thirds longer than 

 the whole body. Legs slender and strongly elongate, with the ? 

 anterior tibiae and disc only of their femora fulvidous white ; <$ hind 

 femora red. Wings broad and hyaline, stigma and nervures black ; 

 areolet quadrate and very small, emitting the centrally broadly 

 fenestrate recurrent from near its apex ; radius apically straight ; 

 nervellus intercepted but slightly below its centre. Length, ^ 10, 

 ? 12, terebra 20 mm. The association of the sexes is purely 

 arbitrary. 



The type occurred at Pilgrim's Best in the Transvaal to Miss 

 Schunke ; and the co-typical male at Durban to W. Haygarth during 

 April, 1913. 



This form differs from the type, which I have examined in the 

 South African Museum, in nothing but the black hind legs with no red 

 markings at all and its much brighter red basal segment.
