5. Dorsum with a median percurrent band extending forward, including tiie head, 

 colored a conspicuous yellowish white, and a similar colored band transversely arranged 

 on the femora: no black spots present. 



6. 7. and 8. Pronotum reddish yellow conspersed with darker fuscous; no triangular 

 black spots visible.— Near the shore of Lake Michigan, Cheltenham (Chicago), October 

 25. 1896. 



Near the Lake Shore at Cheltenham the author visited a point where in the preceding 

 fall some Tettix were found. May i8th, after searching carefully, only six Tetlix ornatus 

 were taken, one triangularis and one Tettigidea. h. fresh growth of green clover with 

 areas of lichens, mosses, and grasses, with various weeds, covered the ground, yet the 

 ground was so light that there was a sprinkling of gravel showing. The power of flight was 

 well developed in ornaius, and the color markings were as follows: 



1. Grayish fuscous, a yellowish white narrow band running the entire length of the pro- 

 notum through the middle, and including the head, widening and including the apical pro- 

 cess behind. Femora externally lichen marked, obscure gray. Black spots on the prono- 

 tum not distinct. 



2. Pronotum with distinct white line on each side of the disc, with two triangular velvet 

 black spots distinctly marked: posteriorly, the pronotum reddish gray. Femora with trans- 

 verse light band on upper margin. 



3. 5. body grayish. 



4. Body grayish marmorate. lichen colored: with indistinct dark spots on the pronotum. 



5. Similar to preceding. 



6. Body conspersed with dark fuscous. This is triangularis. 



7. Young pupa, brightly marked like No. 4 described above. --Cheltenham (Chicago) 

 May 18. 1897.
