 short, 11-jointed, the iirst and second joints enlarged; prosternal

II. Dryops. 



Lulrochus Ixiteiis Lee, oval, bron/.ed, densely clothed with clay- 

 yellow hairs, has been recorded by T)\\vy from Cincinnati. 



Tvlonomus obscunis Lee, subcylindric,-il, piceous. densely clothed 

 with erect hairs, length 6.5 mm., is recorded from the "Southern

 sternum; joints 4 to 11 of antenna' disti nelly lamellate; prosternal 

 spine wide. Five species arc known from North America, two of 

 which ha\'e been taken in Indiana, while a third probably occurs.
