the dorsal lines; indeed, there may be indistinctly discerned two or 

 tbree lateral series of alternating- blotches. 



Ill larger specimens Irom the West, this tendency in the spots to 

 aggregation is still more distinct. The back is crossed by these dotted 

 lines of the number and relation indicated, at intervals of four or five 

 scales; the spots on the intervening space being obsolete. These lines 

 bifurcate at about the ninth outer row, the branches connecting with 

 those contiguous, so as to form hexagons, and these extending toward 

 the abdomen again, decussate on about the third outer row, thus inclos- 

 ing two series of square dark spots on each side. These lateral mark- 

 ings are, however, not very discernible, owing to the confusion produced 

 by the greater number of yellow spots. On the edge of the abdomen 

 are dark blotches, one opposite each dorsal dark space, the centers of 

 the scutelhe being likewise blotched, but so as rather to alternate with 

 those just mentioned. 



Specimens from Indianola exhibit all varieties of coloration.
