 sideratur ut varietas sola I. lineatoris (Grav.), sed differt corpore semper 

 majore et abdomine apicem versus castaneo, capite pone oculos magis 

 angustato, fronte supra antennas profundius excavata, notacuis fere 

 obsoletis, areola metathoracis longiore, feminœ Iatitudine paullo longiore, 

 costa laterali postice magis extrorsum flexuosa, femina prseterea anten- 

 nis annulo albo 8-articulato , coxis intermediis punctis grossis parce 

 obsitis, posticis scopula breviore, apicem tantum internum occupante. 



10. I. impressor (Zett.). — Obs. Ita liane speciem spectet forsitan 

 /. inquilinus (Holmg.), sed vix I. nigricornis (Wesm.), qui major (long. 

 7-8 lin.) a suo auctore describitur. 



11. I. truncatulus mini, — Niger, antennis $ annulo albo, abdomine.
