projecting 2 



Apical lateral angles of abdominal segments acuminate, slightly 

 projecting ; color brown sordida 



2. Third antennal segment about twice the length of the second ; head 



not narrowed in front dimidiata 



Third antennal segment shorter; head distinctly narrowed ante- 

 riorly calva
