" A smaller and more slender species than T. nic/robalteata, with 

 which it agrees in having the abdomiual segments banded with 

 black ; but it differs in liaving the central area on the base of the 

 median segment [metatlioracic areola] open at the apex ; the lateral 

 area shorter and broader at the apex ; the petiole longer compared 

 with the second segment ; the wings not infuscated at the apex ; 

 the areolet slightly larger and receiving the recurrent nervure in 

 the middle .... if anything, before the middle" (Cameron, loc. 

 cit.).

(^ 5 . A pale flavous species, smooth and nitiduloiis, with black 

 markings and short white pubescence. Head with only the ocellar 

 i-egion, and a curved occipital line, black. Antennce stout and as 

 long as the body, black, with the flagellum basally infuscate and 

 the scape beneath flavous. Thorax: mesonotum black, with two 

 discal stripes and the lateral margins flavous ; metanotum flavous, 

 with its base, centre nari'owly, sides broadly, and a large apically 

 constricted and basally incised mark at its apex, black ; lateral 

 areas longer than broad and apically constricted, basal area wanting, 

 lateral carinaj straight and oblique, the spiracular curved, extending 

 to apex and forming a single area from base to apex of metathorax, 

 which is basally constricted by the lateral arese. Scuielhim 

 flavous, with or without a central apically dilated black mark. 

 Abdomen with all the segments broadly black basally ; terebra 

 fully a quarter the length of the body (3 millim.). Legs with all the 

 femora broadly black-marked above ; intermediate tibia) infuscate 

 behind, the hind ones with their base and a broad band nigrescent ; 

 posterior tarsi also nigrescent. Wings clear hyaline, with the 

 nervures and stigma black. 

 Length 10 millim.

This is said to be a variable species, with respect to tlie extent 

 of the black markings. " The scutellum may have no black mark ; 

 the size of the black lines on the legs varies, that on the hind 

 femora may be cleft, wholly or in part ; the pleurae may be marked 

 with black and, as is the case with many Pimplides, there is a 

 considerable variation in size," which is not indicated. This 

 species closely resembles my Orientotheronia macidijjes, but may at 

 once be distinguished by its lack of metatlioracic apophyses.
