111 the table of Halictm two supposed British species are sunk, 

 longulus Sm. and avnoldl E. Saund. The former appears to me merely 

 a small slender variety o£ malachiwiis, far less remarkahle than some 

 variations that occur in other species. The two forms as a rule are 

 recorded from the same localities, where these have been much investi- 

 gated, and, although longulus 5 has been taken by several collectors 

 in numbers at the end of Jvily and in August, no S distinct from 

 mala cJi urns seems ever to have occurred. The genital armature hgured 

 by Saunders as that of longulus is clearly that of H. jjauxillus v. 

 iminarginafus, very large males of which are frequent. Smith's sup- 

 posed males of longulus were merely fulvicornts K. On the Continent 

 a c? has been assigned to longulus, but, although the $ is common, this 

 c? is so rare that I have been unable to procure one, and I suspect that 

 it will prove to be either a variety of malachurus or to belong to some 

 other species more rare than longulus. As we noticed on one occasion 

 that a colony of K. maculatus produced a second brood in September, 

 of larger size than the fresh individuals that emerged in July, it may be 

 that a similar case is presented by malacliurus in some seasons. As to 

 S. arnoldi the S , in my opinion, is at most a slight variety of mimi- 

 fissumcs K., while the 5 type belongs to a different group (sensu restr.) 

 of Halictus, and has no connection with the 6 . But for the supposi- 

 tion that these were sexes of one species, I do not think that Saunders 

 would have described it. 



Although I have not seen British specimens agreeing with recent 



descriptions, made after examination of Schenck's types, of pauxillus, 



ours being the species called inimarginatus Sch. on the Continent, yet 



the characters supposed to separate the two are so slight, and Bi-itish 



specimens of imniarginatusare so variable, sometimes closely approaching 



pauxillus, that I have considered the two forms as mere varieties of 



one species.
