Black ; legs from femoi-a red ; basal half of hind tibiae black. 

 Wings brown, centrally darker ; hind wings with indications of 

 cubital and radial nervui'es. 



Length 22 mm. 



Habitat : Rubiana, New Georgia, Solomon Islands. Type in 

 the Hungarian National Museum, Budapest. 



Easily distinguished by the smooth petiole and red femora. 



This species closel}'^ resembles tS. ruhri2)es Morley, from which 

 it differs in the smooth petiole, propoi'tions of l)asal flagellar

(S . Head semicircularly rugose in front, trans- suloate below 

 scrobes. Tubercles small and transverse ; vertical carina 

 prominent ; occiput trans-striate ; posterior margin of head 

 truncately bordered. Antennae very slender and elongate, 

 21 mm., second flagellar joint half as long again as first, third 

 half as long again as second, shorter than first and second 

 together. Thorax superficially but confluently punctate, the 

 rather short prothorax transcarinate, its posterior margin smooth. 

 Scutellum smooth, the basal sulcus crenulate. Mesopleurse 

 longitudinally bisulcate ; metapleurse rugulose, bisulcate above. 

 Petiole minutely transaciculate and apically explanate, shorter 

 than rest of abdomen, which is finely alutaceous and somewhat 

 shining. Hind coxfe (4 mm.) rather shorter than femora (5 mm.), 

 which are bidentate, with four small teeth before the central tooth 

 and another beyond it. Lower nervure of external median cell 

 in fore wing deflexed in the form of a comma at base, apically 

 wanting ; hind wing with costal nervure only, emitting a slight 

 spurious nervure from its apex below the three f renal hooks. 



Black : head except apices of mandibles, the tubercles and the 

 occiput centrally, base of antennae, second and fourth segments 

 la,terally basally, whole of third segment, anterior legs except 

 coxse, and apical third of hind femora including the teeth bright

 covered with dense white pilosity, and on the legs, the hairs, 

 though less dense, are longer and more conspicuous. Frons,
