aa. Thorax with four carhue; maxillary palpi, awl-shaped; mandibles 

 toothed. PSEUDOPSIS. 



Pseudopsis columbica Fauv., reddish-brown, 2.5-3.5 mm. in 

 length has been taken in numbers near Detroit. 



Subfamily VII. EUAESTHETINAE. 



Small, rather slender species having the antennae inserted before 

 the eyes at the base of the labrum ; tarsi four-jointed ; eyes moderate 

 in size, convex, coarsely granulated, located very close to the base of 

 head; labrum usually denticulate in front; antenna?, mouth parts 

 and thorax much as in the subfamily Stenina?. Three genera repre- 

 sent the subfamily in the United States. Specimens of but one of 

 these have been taken in Indiana, though those of the others may 

 oci-iir. The only paper treating of the subfamily is by: 



Casey. ''Contributions to tbe Descriptive and Systematic Cole- 

 opterology of the United States," Part I, 1884 (published 

 privately) . The genera Euc&sthetus and Edaphus are treated 

 on pp. 18-31.

Ten species of this genus are listed by Casey, loc. cit. ; nine of 

 which he describes as new. Two of the ten have been taken in the 

 State.
