From a study of specimens from various places in the West, I am 

 convinced that the species described by Thorell from Colorado as 

 Tarentula modesta is the same as the Eastern L. frondicola, and Thorell's 

 name would have to be used except that it is preoccupied by Keyser- 

 ling's species. In 1890 Marx proposed the name pudens to take the 

 place of modesta; but as the species had been described by Emerton in 

 1885 as frondicola, the latter name must stand. A study of the male 

 specimen upon which L. nigroventris was based convinces me that it 

 is the same as frondicola. 



L. frondicola is a widely distributed species, conmion especially in 

 the central, northern and mountainous parts of the United States. It 

 is found most frequently in and at the edges of woods, among fallen 

 leaves and sticks. Specimens from the dryer parts of the West, as 

 with various other species, show a tendency to lose the dark coloration, 

 especially that of the venter. Some specimens have the venter entirely 

 pale.

(Trans. Conn. Acad., VI, p. 483, PI. XLVI, figs. 4, 4a, 4b.) 

 Female. — A wide median light band, widest between third eye row 

 and dorsal groove, and from there narrowing backward to end of 

 cephalothorax, commonly constricted or indented at groove, also 

 narrowing and passing forward between eyes of third row and reaching 

 those of second row. Tegument of middle band light reddish brow^n
