The above description is, in one or two respects, 
imperfect. The specimens were received by Prof. Bolivar 
somewhat damaged, with the result that the structure of 
the antenne could not be made out. The antenne ditfer 
somewhat in the two sexes. In both sexes, they have 
usually eighteen segments, but there is variation in ‘this 
respect An examination of twenty females showed seven- 
teen with eighteen segments and three with only seventeen 
segments. Anexamination of ten males revealed five with 
eighteen segments and five in which the third segment 
from the base showed a very distinct, though apparently 
not complete, division into two. This would give nineteen 
segments, but, as already stated, the division is not quite
