E. T. Atkmson— Notes on Indian Rliynchota. [JTo. 1, 



coutigiious before it : anteunfe 4-jointod, 2-3 joints much compressed: me- 

 Bostettinin deeply furrowed : bucculaa much elevated, rounded : spiracula 

 of the first ventral segment visible. 



Stal distributes the species of this genus amongst the subgenera 

 Pseiidaradus, Megymenum, Anoplocephala and Pissistes. The two first 

 are found in India, the third in the Eastern Archipelago and the last in 

 China. 



Pseiidaradus : — Head with the sides tumid at the eyes, unarmed : 

 pronotum anteriorly with a tubercle in the middle : lateral margins of 

 the abdominal segments distinctly produced posteriorly in a lobe or 

 tooth ; prominulous before the middle, or almost in the middle, in a tooth, 

 or small very obtuse lobule ; 2-3 joints of antenuEe amplified on both sides. 



Megymenum : — Head furnished before the eyes on both sides with a 

 tooth, or, of tenest, a very distinct spine : pronotum anteriorly in the mid- 

 dle not, or only very slightly, tumescent : lateral margins of abdominal 

 segments posteriorly distinctly produced in a lobe or tooth, prominulous 

 before the middle, or, in the middle, in a tooth, or very obtuse small 

 lobule : 2-3 joints of the antennse amplified on both sides.

Ovate, obscurely cupreous or brassy-black : head black, much canali- 

 culate ; antennte short, compressed : pronotum with the sides expanded, 

 spine anteriorly acute: scutellum and hemelytra obscurely cupreous, 

 immaculate: wings sordidly whitish, abdomen above black, beneath 

 cupreous: feet blackish, first pair of femora dentate inwards (Fabr.). 

 Closely allied to M. inerme, Herr. Schiiff., differs in having the 2-3 joints 

 of the antennfe broader, the former shorter, the latter longer, and the 3-4 

 joints together longer than the second. The pronotum is unarmed, 

 margins bisinuate ; margin of abdomen somewhat dentated. Lono- 15
