and extreme base) and palpi pale flavous ; face and clypeus closely 

 and uniformly punctate ; frons and vertex nearly as strongly, 

 though less closelv, punctate. Antennce as long as the bodv, 

 black, with the scape centrally flavous beneath. Thorax closely 

 and subunifonnly punctate ; metanotum with dense long silvery 

 pubescence ; its basal area short and subtriangular, strongly 

 constricted apically, areola extending to the petiolar area, obliquely 

 constricted basallv and gradually contracted to the excarinate apex ; 

 propleura3, centrally and apically, irregularly striate ; mesopleura3 

 linely and closely striate before the glabrous speculum. Abdomen 

 ferruginous, with the basal segment and the basal two-thirds of 

 the second, black. Leys testaceous, with the anterior flavidous ; 

 coxae, posterior trochanters, base of their femora broadly, hind 

 tarsi and apices of their tibiae, black. Wings hyaline, with the 

 tegulae pale flavous, the stigma and nervures black.

This species is said to differ from H. spinipes in not having the 

 frons carinate, and in the more sparsely spinulose tibiae and tarsi ; 

 from //. pilosella we are told (Entom. 1906, p. 250) that it is 

 distinct in its basallv acuminate petiolar area, the basally strongly 

 constricted metanotal areola, and in having the apical half of the 

 hind femora and nearly the whole of their tibiae red.

GEXOTYPE, T. striata, Cam. 



Head not dilated behind the glabrous eyes ; clypeus discrete^ 

 apically rounded and laterally strongly foveate ; mandibles large, 

 with subequal teeth : cheeks distinct. Xotauli indicated, but very 

 short; metathorax distinctly areated, with oval spiracles. Scu- 

 tellum convex, coarsely striolate laterally and apically. Abdomen 

 elongate and compressed, with the spiracles of the basal segment 

 small, circular, and behind the centre; terebra very strongly 

 exserted. Tarsal claws pectinate. Wings short, with no areolet ; 

 second recurrent emitted from the external cubital beyond the 

 submarginal nervure ; basal nervure continuous through the 

 median.

Cameron says this genus is allied to Campoplev, but I consider 

 the absence of an areolet places it much closer to Charops, Holmg., 

 from which it would appear to differ in little but its discrete 

 clypeus, distinct metanotal area?, and apparently internally entire 

 eyes. Schmiedeknecht (Opusc. Ichn. p. 1524) places it next to 

 Nepiesta, Forst., by adding the supposititious characters : hind 

 metatarsus more than a third of the tibial length and not dilated, 

 the parallel nervure not interstitial, and the eyes not internally 

 etnarginate.
