[The sexes are so unlike in size and appearance as to have long 

 been mistaken for species. The color of the integument in either 

 sex may be entirely ferruginous, or entirely piceous above ; the legs 

 pale to ferruginous, with the tibiae and tarsi frequently dark ; the 

 punctuation of the thorax and elytra is coarse and deep. Male : pu- 

 bescence above inconspicuous, grayish when the integument is pice- 

 ous, yellowish when ferruginous, that of the underside is denser, long 

 and silvery ; thorax with a denuded line each side of a more dense 

 pubescent median stripe; antennae not annulate, brown or ferrugi- 

 nous. Female : the pubescence is grayish yellow, according to the 

 surface color ; head, thorax, scutellum, sides and apical region of 

 the elytra and a broad irregular fascia at middle of more condensed 

 pubescence sometimes trilineate on the thorax ; underside piceous to 

 rufous, pubescence dense. This species breeds abundantly in hickory 

 (carya) and butternut {Juglans ciuerea) and may be taken during 

 June and July.] " Ham."

 [Piceous, densely clothed with very fine inconspicuous gray pubes- 

 cence above, longer beneath ; the stripes on the elytra are submar- 

 ginal, from, which proceed obliquely backward three bands which 

 may be mere dents or prolonged to the suture meeting those of the 

 opposite side. The thorax has often two black spots on each side and 

 each elytron three. The larvae frequently destroy the white elm 

 ( JJlmiis aviericana) when planted as a shade tree, and have been 

 found under the bark of the slippeiy elm ( U. fulva) Fitch, and under 

 that of majjle (Acer) Harrington.] " Ham."
