SOME NOTES ON THE GENUS MYRMICA, LATR. 5 



I do not propose to give a full description of each species, but only 

 to point out the most important characters. 



1. Myrmica Isevinodis, Nyl., Acta soc. sc. Fennicre, ii., 3, 1846, 

 p. 927, ^ 2 ^. 



M}/rmica laevinodis, Curtis, Trans. Linn. Soc, xxi., 1854, p. 213. 



Myrnuca loni/israpus, Curtis, Trans. Linn. Soc, xxi., 1854, p. 218.

 1855, p. 122. 



Li the ^ and J the scape is cylindrical near the base and evenly 

 and gradually curved ; the club of the antennae more or less distinctly 

 four jointed ; the frontal area is smooth and shining ; the petiole is 

 somewhat rugose ; the post-petiole smooth and shining ; the spines 

 of the epinotum are not longer than their basal width, and the space 

 between is smooth and shiniiag. The rugosity of the body is less than 

 in all the rest of the genus. In the ^ the scape of the antennae is as 

 long as half the funiculus and is gradually curved near the base ; the 

 club is more or less distinctly five jointed ; the frontal area is smooth 

 and shining, or slightly shagreened ; the intermediate and posterior 

 tibife, especially the latter, are furnished with long suberect hairs. 



The distribution of this species, according to Emery''^'' is North and 

 Central Europe, further south in mountains ; North Asia to East 

 Siberia and Manchuria, also in Japan. Wheeler'-'' states it has recently 

 been introduced into the United States. In 1908 he found three 

 colonies in Massachusetts, and gives good reasons to show it is not 

 indigenous to North America. Smith'-'' describes and figures a 

 gynandromorphous specimen which combines characters of the male, 

 female, and worker. It was captured by Chappell in Dunham Park, 

 Cheshire, who presented it to B. Cooke'"', who also recorded it. 



Wasmann'^" describes an ergatandromorph, in which only the 

 colour of the head is that of the worker, and the ocelli are smaller 

 than is usual in the male. In other respects the species is a normal 

 male. I have found males in the nests in June, males and winged 

 females in August, and at large in September. 



The British distribution as far as is at present known to me, is as 

 follows : —

 mouth, Hereford, W^orcester, Warwick, Lincoln, Leicester, Notts., 

 Cheshire, Lanes. S., Yorks. N.E., Yorks. S.W., Durham, W^estmore- 

 land and L. Lanes.
