 the la;ter enlarged as in Cit/wirt^i. Mandibulary combs 6 (5), Guathochilariuni 

 -om.^what spatulate, stipes separated attennaied at the lKise,mcntum cntire,f.\po<^'d. 

 l)romentum divid-^l almost as in Camhala or Iid</morph(i\ lingunl lobes denticulated. 

 Segments constricted in the middle, the anterior ten segments striate from the feet t>' 

 the pore, striae diminishing on the otlier>: at the junction of the anterior and posit 

 lior part", of almost every segment are round impressions, larger than the lepugtia-
