2 PENTATOMIDyE. 



British India. This view I have followed, especially as the four 

 excluded Neotropical divisions are those most open to controversy. 

 These subfamilies do not lend themselves with facility to the 

 requirements of a synoptical key. It is a consensus of general 

 characters rather than the prominence of a few peculiarities that 

 enables these divisions to be recognized and maintained. 



Syno2)sis of Subfamilies. 



A. Hemelytra longer than the body, folded in 



at the base of membrane ; head alvAays 



clypeated Plataspidina'. 



B. Hemelytra straight, not folded in at base of 



membrane. 



a. Primary and subtended veins of wings 



remote, including a central broad area ; 



haraus present, 

 rt. Scutellum covering the whole of the 

 hemelytra, excepting extreme base of 

 outer margin Scutelhrino'. 



b. Primary and subcostal veins of wings 



usually conterminal and diverging at 

 apex, somewhat parallel ; hamus usually 

 absent. 

 h, Scutellum large, but not covering the 



outer margin of corium GrajJiosowatino', 



c. Scutellum of moderate size, coi'ium 

 always exposed. 

 a. Basal ventral segment almost com- 

 pletely covered by the metasternum ; 

 scutellum variable in size and shape. Cydnino-. 

 v. Spiracles of basal ventral segment 

 hidden by posterior margin of meta- 

 sternum. 

 a^. Scutellum extending to about or 

 beyond middle of abdomen, 

 rarely shorter, if shorter the 

 apex narrowed and only slightly 

 or very slightly produced behind 

 the frena; membrane moderate or 

 small. 

 a\ Tarsi with three joints. 



a^. Eostrum of variable size, but 

 passing anterior coxte. 

 (v'. Eostrum slender ; basal 

 joint not incrassated, nor 

 inserted at labrum .... Pentatomino-. 

 h'. Eostrum robust ; basal joint 

 incrassated, inserted at 

 labrum Asoimuf.
