Pedicel five times the length of funicle joint 1, which is abruptly short and narrow, 

 circular or semihemispherical, not more than twice the size of the single ring-joint 

 and of the same shape nearly, and one-third the size of funicle 2; the latter much 

 larger, hemispherical (cephalic end truncate); all funicle joints hemispherical, be- 

 coming gradually more wide and short toward the club, so that the 7th or last funicle 

 joint is somewhat lozenge-shaped; club conical, the segments less distinct, about 

 equal in length to the last 3 funicle joints combined, or shorter. In dead specimens, 

 genitalia exserted.
