On new Shells from South America. 507 



narrowed anteriorly, the basal area centrally sulcately im- 

 pressed, on each side of which are two callosities making a 

 transverse series of four in all, the central ones largest; 

 scutellum callous at base; elytra longly passing the abdo- 

 minal apex; legs slender, pilose_, intermediate and posterior 

 tibiae almost equally wide apart. 



This very peculiar genus is to be readily separated from 

 Tribelocephala and Opisthoplatys by the long fleecy clothing 

 to the head. 



Apocaucus laneus. 



Head and pronotum castaneous brown, the long fleecy 

 clothing to the former pale brownish ; scutellum and elytra 

 fuscous brown, the latter with the marginal areas paler ; 

 body beneath and legs pale castaneous brown, the femora 

 paler and more brownish ochraceous ; abdomen beneath 

 smooth and shining ; legs and antennae finely pilose. 



Length 5^ mm. 



Hah. E. Himalayas ; Kurseong. 



Closely resembles a Monophlebus on the wing [N. Annan- 

 dale) . 



Postscript. — The title of this paper, " Oriental Rhyn- 

 chota," signifies Rhynchota from the Oriental Region as 

 generally understood in zoo-geography. The term, however, 

 appears to be sometimes used inexactly, as quite recently 

 (Ann. Soc. Ent. Belg. 1909, p. 184), under the heading 

 '' Hemiptera nova orientalia,^^ Bergroth describes species 

 from Australia, Tasmania, and New Caledonia.
