dense and sliort pale pilosity. Wings hyaline throughout, with 

 the stigma testaceous and the nervures darker ; apical abscissa of 

 radius basally curved, the basal straight and double the length 

 of the areolar petiole.

No remark is made by its author upon the possibility of any 

 sexual relation between this species and the last ; the distinctions 

 between them appear to consist principally of colour, and it is 

 strange that two so closely related insects, from the same district, 

 should have been at first kno\\n only in opposite sexes. 



A single pair in the Indian Museum, from Tenasserim, has 

 passed through my hands ; both sexes agree with Cameron's some- 

 what superficial description, given above, in every respect, with 

 the exception of the relative length of the basal radial abscissa 

 and areolar petiole, which is not more than one-fourth or one-filth 

 of tlie length of the former ; the scutellum is peculiarly broad and 

 dull, the metanotum polislied and strongly nitidulous, with its 

 spiracles elongate and impressed -. the abdomen is sublinear and 

 shining, with the third and fourth segments strongly emarginato 

 apically ; the hind tibiic are unusually stout, basally jjlackish, and 

 the front ones are basallv constricted.

Head narrow and not at all dilated behind ; face elongate and 

 broadly developed below ttie eyes ; clypeus narrowly discrete 

 basally and broadly rounded apically, hardly shorter than the 

 face ; labrum strongly exserted ; upper mandibular tooth the 

 longer ; eyes prominent, internally strongly emarginate, subcon- 

 vergent apically, leaving the cheeks broad. Antemuc not pale- 

 jjanded, but elongate and filiform, with the basal flagellar joints 

 elongate, antl, in J , very strongly nodose at the base and apex ; 

 scape externally excised throughout. Metathorax with no trace 

 of area?, basally punctate, with elongate and very large s[)iracles. 

 Scutellinn and postscutellum distinctly convex. Basal abdominal 

 segment as long as the second and not strongly impressed basally; 

 central segments obliquely incised in their basal angles, with the 

 lateral tubercles obsolete ; terebra shorter than the abdomen. 

 Legs somewhat stout, with the front tibite half the length of their 

 basally incised tarsi ; claws large and strongly curved, though 

 neither pectinate nor basally lobate ; hind femora simple and 

 centrally impressed above. AVings hyaline, nearly al\\ ays with a
