The upper labrum (fig. 5, Nos. 1 and 2) terminates in an acute and 

 robust point. The rostrum extends with its extremity as far as the 

 base of the third pair of legs; it has three joints, the second joint 

 longer than the third and somewhat enlarged toward the apex. The 

 third is narrowed at the apex and has the shape of a nipple. 



The wmgs have the simple and straight venation characteristic of 

 this genus, as can be seen in figure 6, Nos. 1 and 2. Their margin

(fig. 6, No. 3) is finely crenulate and furnished with very short and 

 very slender cilia. 



The legs (fig. 6, Nos. 4 to 8) are rather long, the tibiae longer than 

 the femora, cylindrical, furnished with a row of very short bristles 

 along the iimer upper margm and with six short bristles at the apex, 

 two of which are superior, two internally lateral, one external, and 

 one inferior. The tarsus is cylindrical, with its first joint longer than 

 the second. The pretarsus is composed of two lateral claws and of 

 one median appendix as long as the claws. This appendix is a little 

 wider than the claws and not straight, but in the middle more or 

 less curved in the shape of an arc.
