and rubbish. It varies much in the breadth of its outline, and has 

 the hemelytra and wings of at least three dimensions. Most com- 

 monly in the vicinity of Baltimore the hemelytra are shorter than the 

 abdomen.

Determined as M. petiolata by Mr. Say. 



This is an extremely common species, often found in company with 

 the preceding. Occasionally common in stubble fields after the 

 wheat and oats have been reaped and removed; sometimes, also, in 

 the straw stored in the barns. It may be found hibernating in win- 

 ter beneath stones, logs, and leaves, or in stumps of trees behind the 

 loose bark.

No. 103, Harris' Collection. " New Hampshire, Mr. Leonard." 

 Dr. Harris (upon Mr. Say's own determination) refers this species 

 to Pamera bilobata Say. It does not, however, agree with the descrip- 

 tion of that insect, and upon comparison with specimens is seen to 

 be widely different from it. The P. bilobata is an inhabitant of the 

 Southern States, being quite common in Florida, South Carolina and 

 Louisiana. Its most northern limit thus far observed is in the Caro- 

 linian district of Maryland.
