SUBFAMILY IX. — ZELIN^E. 575 



Frequent in the southern half of Indiana, not taken north of 

 Marion County, April 10— Oct. 11 (IF. S. B.) . Springfield, Mo., 

 April 5 (Davis). Raleigh, N. Car., Oct. 29 (Brimley). In In- 

 diana it is occasionally taken by sweeping herbage in dense 

 woodland during the summer, but in April is often found mat- 

 ing and in small colonies in the crevices of the bark of living 

 black-oak and elm trees, and in autumn is gregarious beneath 

 cover along fence rows and in high open woodlands. The 

 known range extends from Maryland and Virginia west to 

 Kansas and southwest to North Carolina and Texas. A little 

 experience will soon enable one to separate this form from 

 ductus by color alone, but the other characters given in the key 

 and descriptions are stable and easily seen. Regarding the 

 North Carolina specimens at hand Brimley wrote : "Mr. Sher- 

 man took over 100 under the bark of a dead pine near here on 

 Oct. 29, 1900, and we have not seen one since."
