SUBFAMILY I. — MIRING. 665 



Subfamily I. MIRIN^E Reuter, 1910, 128, 155. 



Species above the medium in size and of an elongate form 

 having the head porrect, its front portion usually strongly 

 declivent ; pronotum longer than wide, narrowed in front, im- 

 pressed above near apex but without a distinct collar, the 

 lateral carinse entire ; scutellum large, triangular, with basal 

 half usually swollen and in part concealed ; elytra often di- 

 morphic, when entire the clavus distinct, corium with a central 

 nervure ; membrane usually with only one distinct cell, the 

 smaller one vague or obsolete ; cuneus elongate, its suture often 

 indistinct ; hind coxae almost contiguous ; hind femora elongate, 

 not much swollen ; basal joint of tarsi as long as or longer than 

 the other two united ; arolia large, free, often clavate. To this 

 subfamily, as thus characterized, belong ten of our eastern 

 genera.
