268 THE ENTOMOLOGIST. 



Of this very abundant species, which is found in all parts 

 -of the country, I have examples from Denmark and Sweden. 



23. Halictus minutissimds. 

 Melitta minutissinia, Kirbi/, Mon. Ap. Angl. ii. 61, male, 



female. 

 Halictus minutissimus, Smith, Brit. Bees, p. 44 ; Nyland. 



Revis. Apuni Boreal, p. 246. 

 This is the smallest bee found in this country : it is not so 

 common as the preceding, but is widely disti'ibuted. 



Div. II. — Sect. 2. The body more or less metallic. 



24. Halictus prasinus. 



Halictus prasinus, Smith, Brit. Bees, p. 33, female ; En- 

 tomol. Ann. (1865), p. 93, male. 



This species was first taken by Mr. Dale, many years ago, 

 at Bournemouth, but only a female or two, which were sent 

 to me, together with a number of unnamed Halicti : the 

 locality was carefully attached. On my visiting that spot in 

 1865, I fortunately took both sexes in great plenty ; I dis- 

 covered several large colonies. Last year 1 found the 

 females just making their appearance in June : not a single 

 male was then to be found. I expect it is extremely local, as I 

 could not find one a icvf miles distant from Bournemouth ; 

 I took a few at Poole, a distance of four miles ; and it also 

 occurs at Christchurch, which is about the same distance. 

 It is readily distinguished from all the other species ; the 

 female by its thorax being dark olive-green, and by its 

 having the apical segments very pubescent ; the pubescence 

 is short, fine and griseous : the male has the apical segment 

 of the abdomen rufo-testaceous, a character not occurring in 

 any other known British species. The size is that of the 

 common H. cylindricus, 4|- lines. 



25. Halictus Smeathmanellus. 



Melitta Smeathraanella, Kirby, Mon. Ap. Angl. ii. Append. 

 375, male, female. 



Halictus Smeathmanellus, Smiili, Brit. Bees,p.S6; Ny- 

 land. Revis. Apum Boreal, p. 247.
