STENOMETOPIIN^: 



Genus STENOMETOPIUS Matsumura 



Matsumura, Journ. Coll. Agr. Sapporo 5 (1914) 217. 



Type, Stenometopius formosanus Matsumura. 



Head broadly laminately extended but thick dorsoventrally ; 

 vertex between three and four times as long as interocular width ; 

 eyes deeply set in vertex; posterior margin of pronotum nearly 

 straight; sides of clypeus subparallel; pronotal lateral carinse 

 wanting; temples narrow; antennae inserted close to and be- 

 tween eyes; tegmina with two subapical cells; ocelli beneath 

 border of vertex and not visible from above. 



Through Pythonirvana and Jassonirvana, the relationship of 

 this genus to Nirvana is indicated. Whether or not Stenometo- 

 piellus Haupt 3 * has any close relationship with Stenometopius 

 I do not know. Of his genus Haupt described one species, 

 sigillatus, from Buchara.
