Mr. Green lias sent me 

 a dozen specimens of this 

 distinct species, unfortu- 

 nately in none too good 

 condition (the females have 

 no antennae), which he bi'ed 

 from a decayed Folj/porus- 

 f ungus at Peradeniyaduring 

 June, 1905. They were 

 obviously preying in it upon 

 some species of fungivorous Coleopteron, just as tlie common 

 Palsearctic Ophionid, Thersiloclms moderator, L., preys in Boletus 

 iqniar'ms upon the Heteromerous beetle, Orchesia micans, Pz. 

 (cf. Trans. Ent. Soc. Loud. 1007, p. 38).
