It would probably be utterly impossible accurately to separate 

 most of the older writers' synonyms for this and the following spe- 

 cies (L. tarsalis Westr.), which seem to have been everywhere con- 

 founded with each other, until they were in Kec. crit. Ar. separated 

 and characterized. The reasons, which lead to the conclusion, that 

 the species here described by Westring ought to retain the specific 

 name monticola, I have set forth loc. cit., p. 50; and that name has 

 since been accepted by Westring, L. Koch and Cambridge. Some 

 synonyms from non-Swedish writers, which might have been taken up 

 under this species, I have considered it best to place under L. tar- 

 salis Westr., which seems to be, at least in Germany and England, 

 the more common of the two species. I have myself met with both 

 as well in south as in north Germany. In Sweden both species 

 seem in many places, for example in the vicinity of Goteborg, to 

 be equally common; in others, as for instance here in Upland 

 (Clerck's place of residence) and in Gotland, L. monticola appears to 

 be the more common; but in some places I have found L. tarsalis 

 more plentiful. L. monticola is usually met with in dry and sunny 

 localities (conf. Clerck, loc. cit.), whereas L. tarsalis Westr. fre- 

 quents more grassy and damp places. 



In order accurately to ascertain whither to refer L. monticola 

 C. Koch and L. exigua Blackw., I sent specimens of both L. monti- 

 cola Westr. and L. tarsalis id. to Dr L. Koch and the Rev. 0. P. 

 Cambridge. The latter in L. tarsalis recognized L. exigua Blackw., 

 the former declared L. tarsalis to be identical with L. monticola C. 

 Koch. I have also received from Cambridge specimens of L. tarsalis 

 under the name of L. exigua Blackw., and Bavarian specimens of 

 the same species from L. Koch under the denomination of L. mon- 

 ticola C. Koch. But both L. Koch and Cambridge, on closer examina- 

 tion, have found L. monticola (Clerck),Westr. in their own collec- 

 tions confounded with L. tarsalis, and there can therefore hardly 

 be a doubt, that both C. Koch and Blackwall had seen the right L. 

 monticola, although they overlooked the specific difference between 

 it and L. tarsalis. Among C. Koch's figures of his L. monticola 

 loc. cit., figg. 1446 and 1448 probably represent L. monticola (Clerck), 

 Westr. — L. saccigera Walck., which in contradistinction to L. 

 monticola Walck. and L. saccigera Westr. is stated to have annu- 

 lated legs, we have already above treated (see preced. spec). 



The female of L. monticola (Clerck) is easily distinguished 

 from L. paluslris (Linn.) or tarsalis Thor., as also from (L. agricola
