STRUCTURAL CHARACTERS 

 Plate 25, Figures 19-21 



Head and body with only the normal primary setae. 



Head, viewed from above, as long as wide ; widest part well behind 

 middle ; adf rontal sutures extending to incision of dorsal hind margin ; 

 frons reaching to middle of dorsum; longitudinal ridge almost as 

 long as frons ; setae A 1 , A 2 , and P 1 lying in a straight line ; A 1 and A 2 

 closer together than A 2 and A 3 ; A 2 and A 3 and L 1 well separated (A 3 

 almost equidistant from A 2 and L 1 ) and lying in a nearly straight line ; 

 setae Adf 1 , P 1 and P 2 also lying in a straight line. Ocelli all present ; 

 3, 4, and 5 lying in a line and very close together. 



Prothoracic shield extended laterally to include the prespiracular 

 setae. These setae three in number and situated in a line along the 

 lateral margin of the shield ; IV and V closely approximate and near 

 the anterior lateral angle of the shield, III well back of the other two. 

 Setae IV and V closely approximate and under the spiracle on ab- 

 dominal segments 1 to 6' inclusive, slightly separated on abdominal 

 segment 7, and well separated and lying in a longitudinal line 

 on abdominal segment 8; seta V very short on all the abdominal 

 segments. On the ninth abdominal segment seta I well separated 

 from II and III, anterolaterad of II ; IV and V approximate but not 

 on a single pinaculum. VI well separated from IV and V. Crochets
