Morphological characteristics. Adult female (Fig. 35A) about 2 

 mm. long, the derm membranous throughout or with the cephalothorax 

 tending to be somewhat chitinized. Cephalothorax not divided by in- 

 tersegmental constrictions and not sharply separated from the abdomen. 

 Margins of the abdominal segments projecting somewhat, each with 

 several small ducts, several gland spines and with a rather conspicuous 

 chitinous spur (Fig. 35C) which bears one or two ducts which open near 

 the apex. 



Pygidium (Fig. 34) somewhat acute, with two pairs of lobes. 

 Median lobes prominent, close together, their apices sloping and crenu- 

 late. Second lobes of the same shape as the first but smaller, not bilobed. 

 Between the first and second lobes are two very small gland spines and 

 at the base of the second lobe there is at each angle a large pore with 

 a heavily chitinized rim. Beyond the second lobe are two large gland 

 spines followed by three large pores with chitinous rims, a spine, two 

 large gland spines, a large pore, three gland spines and a spur. Dorsal 

 ducts somewhat smaller than those of the margin, arranged in rather 

 definite rows as indicated in the figure. Microducts very small. Anal
