1903.] 247 



describing under the name of Liiffii, in honour of Mr. W. A. Luff, 

 who has done so much towards the investigation of the Channel 

 Islands fauna. I took females of it also in 1001, and at St. Briac iu 

 1899, but I did not notice its characteristics. This year, however, 

 when recording in the Ent. 8oc. Trantjactions (1803, ])p. 207, &c.) the 

 Hyme7ioptera Aculcata collected by the Rev. A. E. Eaton and others 

 in Madeira and Teuerife, I alluded to some specimens taken by T. V. 

 Wollaston, and named by Smith " Maderce,'' Dahlb., as not being ex- 

 ponents of that species, but being probably referable to the var. of 

 hirsufa with pale hairs on the propodeum, of which I had taken similar 

 specimens in Jersey and St. Briac in Brittany. Even then I did not 

 notice the structural peculiarities which separate the species. When 

 at St. Ouen's Bay this year, however, I succeeded iu catching a ^ 

 and ? in cop., and a careful comparison of the two forms at once 

 revealed excellent differential characters, of which 1 give the result in 

 this paper. Altogether in this visit about GO species were noticed, of 

 which the following are additions to my 1901 list.*

 (probably the atra of Ansted) ; Osmia rufa , L., St. Brelades (proba-
