Three <£ , May 15th, in vineyard north of Silves. 



This species appears to me quite distinct from anything described. 

 I sent a specimen to Prof. Perez, who told me it was unknown to him. 



Panurginus montanus, Grir. — One ? , May 15th ; this rare little 

 species was taken in a vineyard north of Silves. 



Camptopceum frontal e, Fab. — One J, June 9th, Sao Eomao, at an 

 elevation of over 1790 feet ; this is also a rare species in collections. 



Osmia nifa, L. — One ? , hillside near Sao Marcos de Serra. 



O. coemilescens, Latr. and Giraud {nee Kirb} r ). — One $ , one $. 

 Giraud, in his paper on the Symenoptera which infest the brier-stems 

 (Ann. Soc. Ent. Fr., 4, ser. vi) has carefully distinguished two very 

 distinct species, which are mixed in many collections under the name 

 of either cenea or coerulescens, but he refers to coerulescens, Kirby, the 

 Bpecies whose <$ has the apex of the abdomen 3-dentate and the $ the 

 thorax black ; certainly, Kirby in his description says corpore femineo 

 atro, but we have only found one species in England, and that 

 certainly is the one with the 2-dentate $ and the blue-black ? . I 

 say this after a careful examination of Kirby's types. 



O. fulviuentris, Latr. — One $, June 3rd, between Coitnbra and 

 Sao Antonio. 



O. adunca, Panz. — One £ , May 18th, road from Silves to Mon-
