 thus far been of rather rare occurrence.

This is the North American analogue of the European Lygus cam- 

 pestris Linn., if it be indeed anything more than a local race of that 

 species. It is quite as variable here as the L. campestris is in Europe 

 and is distributed over the greater part of North America, including 

 the more temperate parts of the sub-arctic regions. In North Caro- 

 lina .and Tennessee it extends to the summits of the peaks more than 

 7000 feet above the level of the sea.

Capsus invitus Say, Heteropt., 24, No. 21.

 legs lighter yellow, the venter finely pubescent, shining, and more or 

 less embrowned about the disk. Length to tip of hemelytra, 6 mil-

Specimens in my own collection from Massachusetts and Illinois 

 are entirely pale soiled yellow, with the cranium, fore part of thorax 

 and sides of hemelytra brighter yellow ; while others have a dark
