My specimen is more mature and dai-ker, being of a brownish 

 red with paler markings, the thoi-ax also is distinctly punctulate. 

 I regard it as a variety of M. hiiaris. 



Mycotretus sestuans. 



Mycotretus cestuans, Lac. Erot. 170. 



Brazil. 



I have not seen the type, but identify a specimen communi- 

 cated by Mr Sheppard with this species. Further material would 

 in all probability unite it with M. hiiaris.
