Notes OH three species of Microglossa. — Micro(jlossa maryinalls, Gyll. : I took 

 two specimens near here in April last from an old woodpecker's hole in the trunk 

 of a beech tree recently blown down. The hole had evidently been used by 

 starlings for some years, and 1 think, since it had been blown down, by a mouse, 

 as it contained a quantity of fine grass. JJendrophitus punctatus, Herbst, a common 

 starling's nest species, was accompanying the Microglossa. I feel quite confident 

 that a specimen of this species also occurred in the old bat's nest out of which 

 I took Neuraphes carinatns, Muls., Choleva colonoides,J^r., &c., last year (Ent. Mo. 

 Mag., ser. 2, xv, 255), but unfortunately Mr. Tomlin, who took the specimen, has 

 mislaid it. 



Microglossa pulla, Gyll. : 1 have found this species in every fresh titmouse's 

 nest I have examined this year, and it has sometimes occurred in abundance, but 

 1 have failed to find it in one or two old nests. I have also taken it in the fresh 

 nests of the flycatcher and starling. 1 have never discovered it in the nest of the 

 sand-martin, although 1 have searclied ior it carefully. 1 should suspect it inhabits 

 the fresh nest of any species of bird that builds in a hole in a tree. 



Microglossa nidicola, Fairm. : very abundant in the fresh nests of sand-martins ; 

 it seems to disappear as soon as the birds desert their nests in the autumn. 



These three species can be distinguished at once in life by the colour of the
