T/ieronia clathratd, Kviegar, Ber. Nat. Ges. Leipzi-r, 1899, p. Ill ( 9 )• 

 Theronia areolata, Cameron,* Mauch. Mem. 1«99, p. lo2 ($). 



5 . Head flavesceut, with the fi-ons centrally and tlie occiput 

 (except near tlie eyes) brunneous ; face centrally sparsely punc- 

 tate, with the clypeus smooth ; mandibular teeth black and palpi 

 apically fulvous.' Antenmn as long as the body, brunneous and 

 becoming darker apically; scape flavescent beneath, \\ ith a lateral 

 black Une, sparsely punctate and with elongate pale pilosity. 

 Thorax luteous, with the mesonotum brunneous, its sides and two 

 central vittse flavescent ; metathorax uitidulous and impunctate ; 

 areola pyriform with its lateral carinae basally broad and flat and 

 apically acute and deeply excavate ; the external areaB large, 

 shallow and broader than "long ; petiolai area deeper, shorter and 

 obliquely constricted towards the sinuate basal carina), distinctly 



discrete pro- and meso-pleura3 

 glabrous and nitidulous ; meta- 

 pleurae also smooth and sharply 

 carinate below the spiracles. 

 iScaieUum luteous, with its sides 

 and apex flavous, impunctate and 

 densely clothed with elongate, 

 black pilosity ; its basal fovea 

 black and deeply impressed ; 

 postscutellum smooth and sub- 

 glabrous, basally deeply bifoveate, 

 laterally obliquely and acutely 

 carinate, with the central parti- 

 tion triangular. Abdomen brun- 

 neous, with the base and apex of 

 the first segment broadly, the 

 apices of the second and third 

 broadly, and of the fourth and fifth narrowly, flavous ; basal seg- 

 ment acutely carinate laterally to a little beyond its centre, witli 

 the base and sides depressed obliquely beyond that point ; terebra 

 ;5 millim. Legs stout, the biiid coxse and femora suffused with 

 fulvous and their tarsi red. Wings f ulvo-hyaline, witli the stigma 

 fulvous and nervures black ; areolet oblique and emitting the re- 

 current nervure at its apical fourth. 

 Length 12-13 millim. 

 Assam : Khasi Hills {Rothneg). 

 Type of Cameron's species in the British Museum. 

 No doubt, I think, can be entertained resiiecting the synonymy 

 of these two species, although Krieger describes the metanotal 

 areola as twice as long as broad, laterally parallel, and emitting 

 the costula) distinctly beyond the centre ; he adds that the face is 

 broadly and longitudinally impressed, the frons centrally de- 

 ])ressed, the scutellum somewhat convex, the notauli short and 

 the terebra as long as the hind tibiae.
