61. L. myops For^/. — Great Notch (Wheeler); HaHfax (Wheeler). 

 This is the American representative of the European L. fiavus, 



under which name it is sometimes recorded in the literature. The 

 bodies of the workers have a milky white appearance. According 

 to my observations this ant always occupies a definite station, pre- 

 ferring to nest under stones, or leaf-mould in damp, shady woods. 

 The colonies are rather small. The males and winged females may 

 be found in the nests during the first week of August. 



62. L. umbratus mixtus Nyl. var. aphidicola Walsh. — Caldwell 

 (Emery) ; Woodbury (Viereck) ; Fort Lee (Wheeler) ; Great Notch 

 (Wheeler). 



This ant forms much larger colonies than the preceding species. 

 It prefers damp, shady woods and in the Eastern States nests under 

 large stones and in and about old logs and stumps. In the Middle 

 West (Wisconsin and Illinois) it often builds considerable mounds of 

 earth (1-5 ft. in diameter and ,^-i ft. high) around or over decayed 

 stumps. These mounds are perforated with numerous openings and 

 shot through with living grass blades. During winter and early 

 spring, but especially during the latter season, the nests teem with 

 snow-white Aphides and coccids which are cared for by the ants. The 

 males and winged females appear Aug. 2-1 1. 



63. L. umbratus mixtus var. aflEinis Schenck. — This European 

 variety is recorded by Mayr from New Jersey. I have not yet been 

 able to recognize it among any of my specimens collected in the 

 United States. 



64. L. umbratus minutus Emery. — This subspecies was described 

 by Emery from specimens collected in New Jersey and Maine. In 

 my collection there are three workers marked New Jersey, received 

 from Mr. Pergande. 



65. L. speculiventris Emery. — The types of this species are from 

 Caldwell. I have taken it at Fort Lee and Great Notch. The 

 colonies are very large, like those of L. aphidicola, and are found under 

 stones or rotten logs in rich, shady woods. A populous colony found 

 in the early spring at Fort Lee in a pine stump contained thousands 

 of snow-white Aphides of all ages. The females of this species are 

 unknown.
