Descriptions of Neiv Species of Parasitic Hymenoptera. 105 



segment, if anything, longer than usual ; it is completely areolated ; 

 the areola is three times longer than wide, obliquely narrowed at the 

 base, transverse at the apex ; the spiracles are separated from the 

 pleural keel. Second abdominal segment closely, longitudinally 

 striated. Antennae about 34-jointed, shorter than the body. Parap- 

 sidal furrows distinct. First abdominal segment spiracles minute, 

 placed near the base of the apical third. Clypeus separated from 

 the face. Malar space distinct. Occiput margined, but not strongly. 

 Ocelli large, more prominent than usual. Hinder metatarsus shorter 

 than the following two joints united ; claws small, simple. Palpi 

 slender, of moderate length. 



In the Foersterian-Ashmeadian system this genus would come in 

 near Dolichopselcplius and Temeliicha. From the very large size (as 

 in Ophion) of the ocelli and from the colouration I should think the 

 type of this genus is of nocturnal habits. The wings have a slight 

 milky tint. 



* ElCRENA PALLIDIPENNIS, Sp. nOV. 



Eufo-testaceous, the flagellum of antennae, a line uniting the 

 posterior with the anterior ocelli, the parts at the sides of the 

 scutellum, the base, apex and middle of metanotum, mesosternum 

 and base of first abdominal segment, an oblique mark on mesopleurae 

 below the tubercles and the lower side of the metapleurse, black. 

 Wings hyaline, with a slight naiiky tint ; the nervures black, the 

 stigma dark fuscous. ^ . 



Length 7 mm. 



Cape Colony. 



Face minutely punctured, the inner orbits, malar space and base 

 of mandibles pale yellow. Mandibular teeth black. Ocelli amber- 

 coloured, the hinder are separated from each other by a distinctly 

 greater distance than they are from the eyes ; the anterior has a 

 semicircular keel in the middle. Thorax closely punctured, shining ; 

 the lower part of the propleurae, the parapsidal furrows and tegulae 

 are yellow ; the median segment is more irregularly and not so 

 strongly punctured ; the posterior median area is closely, transversely 

 striated. Legs slender, the tarsi longer than the tibiae ; the anterior 

 more than twice their length ; the basal two joints united being 

 longer than them. The disco-cubital nervure near the apex and the 

 upper half of the recurrent nervure are bullated ; the short, trans- 

 verse cubital nervure is much thickened ; the costa between the 

 stigma and where it receives the transverse basal nervure is 

 thickened.
