96 THE entomologist's record. 



is not very detailed however. With the exception of the colour of the 

 legs (which he refers to as red-brown), as far as it went, this descrip- 

 tion tallied with my specimen. Not then having seen the original 

 description, the beetle was submitted to Captain Deville for verifica- 

 tion ; he returns it as S. fonnicetonn;}. It will be noticed that in 

 Mannerheim's original descripton, he says " pedes toti nigri," this 

 being quite in agreement with my insect and not so with Ganglbauer's 

 reference to red- brown legs. Of our British species it is most nearly 

 allied to »S. rratisns, Steph., and is a member of that section, having 

 the penultimate joints of the tarsi simple, and the hind-body not 

 margined. From S. crafixus it may easily be differentiated as follows: — 

 (a) Considerably smaller size ; from a long series of craxfuts I cannot 

 select one that is not considerably larger than fornncetormn. (6) The 

 difference in sculpture, giving the insect a much more dull appearance, 

 (c) By the shorter and more cordate thorax, {d) By the fovea near 

 the base of the thorax. (e) By the narrower elytra, the shoulders 

 being much less pronounced. 



My specimen was taken at Ditchling, Sussex, on August 2nd, 1910, 

 by sifting a faggot stack. Ganglbauer records the species as being 

 found with burnnca rafa : rare ; North and Middle Europe. 



Formica fusca, L, var. glebaria, Nyl., a form new to Britain. 



By CECIL CRAWLEY, B.A., F.E.S. 

 On April 18th, 1909, near Brockenhurst, New Forest, I found a 

 grass-covered mound occupied by a colony of what I took to be a race 

 of F. fusca. The nest was entirely different from the ordinary fusca 

 nest, and the ants were walking about and working on the surface of 

 the mound, showing none of the characteristic timidity of fusca. 

 They were very unlike fusca in general appearance, being duller and 

 more uniform in size. I could find no 5 s or brood in the nest. Last 

 winter I sent some of these ants to Mr. H. Donisthorpe, who found 

 them to correspond exactly with the specimens of [jlebaria sent him by 

 Dr. A. Forel. I have since compared the specimens in company with 

 Mr. Donisthorpe, and am satisfied that they are alike in every 

 particular. 



Nylander's description is as follows : — 



Operaria : nigra nitida valde cinereo-micans ; mandibulis anfcennarum scapis 

 flagellorumque basibus et pedibus vel totis vel tibiis tarsisque piceis seu piceo- 

 rufesceutibus ; ocellis parvis : squama sursum late subtriangulariter subrotundata. 

 Long. ciic. 2. lin. (Acta Sac. Sc. Fennic, ii., 3., 1846, p. 917, Pit. 18., fig. 23). 

 Per totam patriain valde frequens, sub lapidibus prsesertim habitans, cuniculos 

 vastos in terra fodiens. Helsingfors. 



Wheeler points out {Ants., 1910, p. 456) that in the valleys of 

 Switzerland, F. cinerea and the varieties of F. fusca, (jlebaria and 

 rubescens, are the commonest slaves of JF. saju/uinea. Mr. Donisthorpe 

 has recently added rubescens {Fnt. Rec, 1909, p. 258) to our list.
