16 E. T. Atkinson — Notes on Lidian Rhynchota. [No. 1, 



(Dallas). No portion of the inner or apical margin of the corium is 

 covered by the scutellum. Long, 6 — 7| mill. 



Reported from Hong-Kong, Assam, Sikkim (mihi). 



Following Stal, T place in the sub-family Pentatomina those genera 

 of Dallas' Pentatomidcs found in India which Stal distributes amongst the 

 following divisions, and which are distinguished by having the tarsi 3- 

 jointed and the scutellum extended to a distance behind the frena. The 

 species are rather numerous and difficult to arrange, but I have no doubt 

 that we shall, in a short time, be able to give a more exact distribution. 



Group A. 



a. The first group of these divisions includes those genera in 

 which the venter is unarmed at the base, second segment without a 

 spine or tubercle prominulous forwards and reaching, or somewhat so, 

 the metastethium, and sometimes furrowed ; margins of furrow, however, 

 neither callously elevated, nor levigate : anterior margin of the prono- 

 tum very rarely somewhat elevated, levigate or callous : tibiae above 

 generally furrowed or flat and margined, except Agonoscelis, in which 

 they are without a furrow and rounded : second joint of the antennae 

 sometimes not extending beyond the apex of the head : orifices entirely 

 margined, or auriculated, or continued in a furrow. 



6. Corium anteriorly generally confusedly punctured between the 

 costal margin and the intracostal vein, the costal margin anteriorly 

 generally acute or flattened and somewhat laminated, the space between 

 the margin and the vein therefore somewhat broad ; this space rarely 

 very narrow (as in Bi^loxys) with a single row of points : orifices 

 generally continued outwards in a long or somewhat long furrow ; 

 basal angles of the scutellum rarely with a spot or levigate, callous 

 streak : juga sometimes much longer than the tylus and acuminated : 

 anterior lateral margins of the pronotum rarely obtusely rounded : 

 second joint of the antennae sometimes not, or barely, extending beyond 

 the apex of the head. 



c. Head flat or somewhat so, lateral margins acute and laminated 

 or prominulous before the middle in a straight, tooth-shaped angle ; 

 juga generally longer than the tylus, often much longer and contiguous 

 before the tylus : anterior lateral margins of pronotum generally acute, 

 or somewhat so, sometimes laminated ; bucculae not prominulous posteri- 

 orly in a lobe : scutellum posteriorly narrow, or somewhat so : frena 

 extended to rather a distance behind the middle of the scutellum : body 

 never greenish : venter not, unless in the second segment, furrowed.
