THE ENTOMOLOGIST S RECORD. 



new locality in Scotland for this species. I am pleased to say there 

 are still plenty of nests in Parkhurst Forest, Isle of Wight. 



i<. fmra, Li. — On July 7th a $ was captured on the wing at 

 Weybridge, and on the 18th naked $ pupjB were found in a nest under 

 a stone in the same locality. Colonies of this ant were found on the 

 Isle of Mull on April 26th, and in plenty on the Isle of Tiree. This 

 species and M. riKjiwidix, recorded above, were the only ants I found 

 in the latter island, although I was there from April 28th to May 2nd. 



My friend Mr. Mitford gave me ^ ? and dejilated 2 J which he 

 had taken at Rothes in Morayshire, one of the latter being a microgyne 

 not much larger than a medium sized ^ . 



All the races of fm^ca which have been recorded for Britain were 

 found this year, though one will now appear under a new name. 



F. fusca var. (licharia, Nyl. — -First recorded for Britain by Crawley.^" 

 Crawley and I found a number of mound nests in the New Forest in 

 July, (J S , one deiilated $ , and one winged 2 being secured. I found 

 an incipient colony in the top of a mound on July 22nd, which con- 

 sisted of the deiilated $ and some twelve ^ ^ . According to Forel 

 the ants from a colony we found at St. Issey, Cornwall, in April, 1911, 

 also belong to this var. 



7^ fiisca var. riibencens, Forel. — First recorded for Britain by the 

 writer^". Colonies were found in July in the New Forest, and at Seaton 

 in Devon, which contained many J^ ^ , but neither winged nor deiilated 

 $ 2 were obtained. 



F . fiisca var. fiixco-nifibarbiti, Forel. — First recorded for Britain by 

 the writer'-^^ Colonies were observed by Crawley at Seaton, and 

 subsequently by myself when I was with him. I found others at 

 Sandown and Blackgang Chine in the Isle of Wight, in September. 

 When we have obtained more material and <? ^ and ? 2 of all the 

 forms, we intend to work out and publish, if possible, more satisfactory 

 distinctions for all these races. It is clear that in the ^ of riibencens 

 the scale is deeply cut out, more so than in any of the others, in fituco- 

 rutibarhia it is widely but not deeply emarginate, and in fimca scarcely 

 emarginate. 1-^^ have pointed out before that fnnco-riitibarbin lives 

 chiefly in the sand on the borders of rivers, lakes, and by the sea, and 

 f/lebaria in the earth on the plains, fusca being more common in woods. 

 This, however, is not sufficient to go by, since as we have seen t/lebaria 

 occurred with finico-rKfibarbis at St. Issey, and rubesrens with fusco- 

 rutibarhis at Seaton, and ijlebaria and rnbescens both occurred in the 

 New Forest. 



F. fiisca sub-sp. ni/ibarhis, F. — ^This sub-species is very distinct, 

 the greater number of the ^ § in a colony being partly bright red in 

 colour, and might easily be mistaken superficially for ^ ^ of sanr/iiinea
