PEIULISSUS. XILGIDA. 317 



the hind coxae internally, and apices of their femora, black. 

 IVings slightly clouded ; areolet wanting, but with its outer and 

 lower nervures traceable, though entirely fenestrate, and the inner 

 continuous with the straight second recurrent ; radius sinuate 

 before apex ; nervellus extremely strongly postfurcal and inter- 

 cepted a little above its centre. 



Length 9 millim. 



BENGAL : PUSH, iii. 07. 



Type in the Pusa collection. 



The lack of an areolet places this species in the subgeuus 

 Spanotecnus.

 GEXOTYPE, T. albitarsis, Cam. 



Eyes very large, with the inner orbits slightly but distinctly 

 convergent below, vertical orbits striate ; clypeus small, apically 

 transverse and shorter than the labrum ; mandibles curved, basally 

 subtriangular, apically constricted and there obtusely bidentate ; 

 palpi somewhat elongate. Antennae elongate, slender, and with 

 a pale band. Thorax with pale markings ; mesonotum with its 

 discal depression extending beyond the centre to the strongly 

 elevated apical lobe ; inetathorax elongate, evenly convex through- 

 out, with no carinae ; spiracles oval and situated in a concavity 

 halfway between the centre and apex. Scutellum large, roundly 

 and but slightly convex. Abdomen elongate and slender ; petiole 

 long and neither stout nor apically curved ; the first longer than 

 the second segment, with spiracles small, circular and slightly 

 beyond the centre; gastrocceli small and indistinct though dis- 

 tinctly and deeply impressed. Legs elongate and slender, with 

 the hind coxae large; tarsi spinose, with their claws curved, 

 elongate and basally subincrassate ; front tarsi basally sinuate, 

 with their calcaria curved and pilose. Wings with no areolet ; 

 the single submarginal nervure incrassate and very short, one- 

 fourth of the length between it and the emission of the second 

 recurrent nervure ; lower basal emitted from the median a little 

 beyond the upper basal nervure.

This genus is at present known in the male sex alone. 



Its author says (loc. cit.) "In the form of the abdomen it does 

 not differ much from Mesoleptus,* but in other respects it differs 

 completely from that and from any known genus of the TIIY- 

 PHOXIDES. It is undoubtedly nearly related to Baliena, as is 



* This must be accepted with reserve, since Cameron was at that tii 

 describing species of Lissonota (PiMi'LiN.E) as Mesokptus '. C. M.
