wings hyaline, the nervures and stigma black ; the tegulte whitish 

 testaceous. J . 



Length 5 mm. ; terebra 1 mm. 



Cape Colony. Stellenbosch. 



Pace closely punctured ; the clypeus smooth and shining. Man- 

 dibles and palpi rufous. Front and vertex smooth, the former 

 thickly covered with white pubescence. Antennae 19-jointed, stout, 

 the third joint slightly longer than the fourth. Thorax smooth 

 and shining ; the metanotum largely, obliquely depressed at the 

 base ; the areola large, the base not clearly closed ; the middle 

 widened, 4-angled, the apex transverse ; the base slightly, obliquely 

 narrowed ; the apical slope depressed in the centre, the sides 

 obliquely sloped ; the sides, at the top of the apical slope, toothed. 

 Abdomen smooth and shining. Transverse median nervure in hind 

 wings received distinctly beyond the transverse basal. Stigma 

 large. 



The petiolar area large, almost square ; the median segment 

 regularly areolated ; the lateral apical area is somewhat strongly 

 transversely striated. 



LIENELLA, Cam. 



This genus of Hemiteliui was described by me in the Transactions 

 of the South African Phil. Soc, xv., 196, 1905. In the collection of 

 the Cape Museum are some specimens which throw some light on the 

 genus, but not enough to properly elucidate the generic distinctions. 

 There seems to be two groups : one, represented by L. nigriceps, with 

 a long, narrow abdominal petiole and sharply defined metanotal keels 

 and arege, of which I have only males, and, unfortunately, all of 

 them have the apical joints of the antennae broken otf. Of this 

 group I have to describe another new species, which differs consider- 

 ably in the structure of the areas on the median segment. 



LlENELLA CANALICULATA, sp. nOV. 



Black ; the pronotum, mesonotum with scutellum, and pro- and 

 mesopleurae, red ; the sides of the second and third abdominal seg- 

 ments, the apex of the second broadly and of the third narrowly, 

 testaceous ; legs black ; the anterior tibi® and tarsi obscure testa- 

 ceous ; the hind tibiae with a white band at the base, the white 

 colour obscured with testaceous. Wings fuscous- violaceous, a clear 

 hyaline cloud on the basal fourth of the anterior and on the basal 

 half of the posterior, a squarish cloud at the stigma and a more
