podial shields, but here too the nientum is planted between an 

 anteriorly directed prolongation of the sternal part and the jugular 

 region. The geniti-ventral shield is nearly hexagonal; its three 

 fore-inargins follow the margins of the metapodial and sternal 

 shields; its three hind-margins form distinct angles. The anal 

 shield is nearly triangular. There are 8 hairs on the sternal shield, 

 2 between the genital and metapodial shields, 2 on the hinderhalf 

 of the genital shield, two on the anal shield one on each side of 

 the anus, and two between the genital and anal shields. Epistoma 

 about the same (Fig. 28) as that of the male. Hypostoma (Fig. 29) 

 with exterior malae abruptly broken distally, and sharp, nearly 

 triangular inner malae. The bases of the maxillae leave a broad 

 split, through which the base of the ligula is visible.
