A CONTRIBUTION TO THE KNOWLEDGE OF 



pressions nearly or quite obsolete, their position indicated merely by the 

 pores of the stigmatic furrows. Marginal spines (Fig. 18D) quite large 

 and stout but sharply pointed, set quite close together and arranged in a 

 very definite, single row. Anal cleft of ordinary depth. Anal plates (Fig.

 plates, left half dorsal, right half ventral; C, foot of adult; D, marginal 

 spines in region of stigmatic depression. 



18B) of ordinary form, each with four apical setae, three subapical setae 

 and with a single long fringe seta on each side. Antennae (Fig. ISA) 

 long and slender, eight-segmented. Legs well developed, the tarsus (Fig. 

 18C) somewhat curved and slightly narrower than the tibia. Digitules 

 of the claw slender, not greatly expanded at the tip. 



Notes: This determination is based upon general resemblance and com- 

 munity of host. Unfortunately none of the eggs contained in the ovisacs hatched 

 and the first stage larva cannot be described.
