I cannot apply Biirmeister's description, or a more explicit 

 account of the characters of the insect received from Dr. Ilagen, 

 to any species I have seen, with absolute certainty. Neverthe- 

 less I think the species probably identical with the next-noticed, 

 S. injurius. Burmeister states he had seen several males. How- 

 ever, I believe he did not know the male of either costatus or 

 subcostatus. His types possess no prothoracic valve ; neither does 

 any specimen of Ilaploglenius in Ilagen's collection, as he in- 

 forms me ; hence I doubt not that all are females.
