 near the mesal edge and a short seta posteriorly. Labial palps 

 1-segmented; four microsensillae and a pair of short setae on the 

 glossa between the labial palps. 



Legs with tibiotarsus small, nearly twice as long as broad, bearing 

 a simple claw. 



Abdominal segments 1-8 each with three dorsal annulets, a pre- 

 scutum, a scutum, and a scutellum; each annulet with a transverse 

 row of setae except the last annulet of segments 6-8. Segments 7-9
