Habit. Occurring in cracks in the bark. But a few specimens 

 were found and in each case the scale was destroyed in searching for it. 

 The second exuvium is very large but does not inclose the adult.

 first stage ; C, extremity of microduct ; D, antenna of first stage. 



Morphological characteristics. Adult female (Fig. 38 A) about 

 .75 mm. long, elongate oval, tapering posteriorly, derm membranous 

 throughout except for the pygidium, the greater part of the body oc- 

 cupied by the cephalothorax. Margins of the abdominal segments pro- 

 jecting but little, without gland spines but with numerous small ducts. 

 Dorsum of the abdomen without ducts. 



Pygidium (Fig. 37) rounded, bearing two, or perhaps three, pairs 

 of lobes. Median pair quite large with a deep notch on the outer margin, 

 separated by a small space in which are two small gland spines. Second 

 pair very small, low and rounded. Between the first and second pairs 

 is a small gland spine and a pore prominence. Beyond the second lobe 

 is a rather large gland spine, a pore prominence, and a sharply pointed, 

 chitinous prominence, a small chitinous tooth, a spine and two gland 

 spines. Ducts few, those of the dorsum smaller than those of the margin, 

 their arrangement as indicated in the figure. Microducts very long and 

 slender, terminating in a structure of the type indicated in Fig. 37C. 

 Anal opening moderately large, somewhat cephalad of the center of the 

 pygidium. Ventral side with three rows of small ducts. Circumgenital 

 pores lacking. 



Second stage resembling the adult but without dorsal pores.
