9 . A fulvous species, with black markings, the wings apically 

 infumate and the stigma pale. Head fulvous, with the face 

 punctate throughout and flavescent above ; clypeus glabrous and 

 the mandibular teeth black. Antennce stout and bruimeous, be- 

 coming darker towards their apices, with the scape paler. Thorax : 

 niesonotum piceous with its sides aud two central vittae flavous, 

 the scutellar fovea aud lines near the tegulae black ; metathorax 

 basally black, widened laterally to the apex of the spiracles ; 

 areola deplanate and subquadrate, the external areae longer than 

 broad and apically constricted ; central carinae indistinct and the 

 lateral stronger ; pro- and meso-pleurae smooth and shining, with 

 the apex of the former narrowly, a longitudinal line beneath the 

 radix, and an oblique line extending to base of the coxae, black. 

 Scutellum fulvous, with its apex broadly black and the sides 

 flavescent ; postscutelluin flavous, with large basal foveae. Abdo- 

 men rufescent with the segmental apices flavous ; three basal 

 segmeuts basally black, the remainder broadly black apically ; 

 petiolar fovea shallow and extending to the apex ; second seg- 

 ment longitudinally canaliculate basally in the centre, and laterally 

 obliquely incised ; terebra 3 millim. Legs : anterior pairs flavous, 

 with their femora, and the intermediate tibiae and tarsi, fulvescent ; 

 hind coxae broadly black internally at the base, their trochanters 

 apically, femora broadly in the centre, and the tibiae, red ; their

Type in the Oxford Museum. 



" Comes near to T. areolata, but is smaller ; has the thorax and 

 abdomen marked with black, and otherwise may be known by the 

 central area on the base of the median segment [metathoracic 

 areola] being square and not hollowed" (Cameron, loc. cit.).

Theronia iridipennis, Cameron, Tijds. Ent. 1907, p. 99 (tf). 



d . A pale flavous species, smooth and shining, with " a broad 

 line on the centre of the apex behind black." Head with the face 

 densely covered with elongate white pubescence. Antennae ferru- 

 ginous, with the scape flavous beneath. Thorax : mesonotum with 

 three broad infuscate lines ; a black line throughout the meso- 

 pleurse immediately below the radix and a similar one, curving 

 forwards below, on the lower half of their apices ; metathorax 

 with a straight oblique slope and dense elongate white pubescence ;
