 brown ; ocelli minute, reddish, in rear of eyes. First segment of 

 antennje short, blackish outwardly, scarcely projecting beyond the 

 lateral margin of head ; second segment spread over with black, 

 slender, dilated at apex, about four times as long as first ; third 

 segment a little over half as long as second ; fourth segment two-

 acute, but not spinose, often slightly curved backward ; on the

 specimens there is a small bald whitish spot. Corium more 

 densely punctate than embolium ; membrane bronzed, with a dark
