known species. When at rest they lie lengthwise with 

 their flattened underside closely pressed against their 

 places of concealment. This habit, together with their 

 protective coloration, makes it very difiicult to detect 

 them. \Vhen disturbed they jerk themselves from side 

 to side and move ofif rapidly with the gait of a semi- 

 looper. They may be trapped by placing boards or 

 paper close to the trunk or on the ground at the base 

 of their food-plants. They leave their feeding places 

 about day break, but during their earlier stages do not 

 ■.vander far away. The Uxjvx of the following species 

 have been described, but additional notes are still 

 needed for most of these. Aholibah, amatrix, amestris, 

 arnica, antinympha, aspasia ( ?), badia, beutenmiilleri, 

 blandnla, californica, cara, ceroganm, clintoni, coc-

They are not general feeders and oak, hickory, 

 poplar and iviUoiv are the principal food-plants. A 

 paper on the same will soon appear in the Lepid- 

 opterist.

In re Mr. (jrinnel's article in June 15 number I look 

 a lot of Hepialus lenzi one year at Stockton. One
