The insects of this section are distinguished 

 from the preceding by two principal circumstances, 

 the interior laciniae are much shorter than the ex- 

 terior with tops not involute, and the antennae of 

 the males are not so long as the thorax. The spe- 

 cies that enter into the present subdivision of the 

 section, differ from those of the next, in the form 

 of their proboscis, which is subulato-conical; in 

 the substance of the apex of the valvulae, which is 

 coriaceous J in the figure of their lip, which is 



square ;
