 Placostermim alces, Stal, En. Hem. v, p. 107 (1876). 



2 . Very like P. taurus ; differs in having the lateral process of 

 the pronotum longer, truncate at apex, with the apical angles promi- 

 nulous in a small tooth : scutellum convex at the base, depressed behind 

 the posteriorly rounded and gradually inclined convex part (Stal). 

 Long, 21 ; broad, 12 ; exp. horns, 16 mill. 



Reported from Ceylon, Calcutta (?).

f?, ?. Sordid yellow-whitish, punctulate ferruginous-fuscous: 

 1 — 3 joints of antennae also basal half of fourth joint, sprinkled fuscous- 

 ferruginous, last ferruginous, pallid at the base : membrane grey, veins 

 fuscous : feet sprinkled ferruginous : anterior lateral margins of the 

 pronotum somewhat sinuated, obtusely crenulated, lateral angles ob- 

 tusely produced, obliquely truncated at the apex and anteriorly sinuate ; 

 apical margin of the corium very slightly sinuated outwards. The d* 

 has the anal segment deeply subsemicircularly sinuated at the apex, 

 apical angles acute. Close to P. taurus, Pabr., but is smaller, lateral 

 angles of pronotum not so long and less deeply produced, more obliquely 

 truncated at the apex and unisinuate, anterior lateral margins some- 

 what straight before the middle, scarcely rounded, more obsoletely and 

 more obtusely crenulated (Stal). Long, 16 — 19 ; broad, 10 — 11 mill. 

 Reported from India : Dikrang (Assam) .

 produced part parallel : sterna not elevated ; posterior feet distant {Stal.),
