through the anal opening. Circumgenital pores entirely lacking. In the 

 early second stage female the derm is membranous, except for the pygid- 

 ium. Pygidium (Fig. 31C) with two pairs of prominent, spatulate lobes 

 and outside of these a third pair of lobe-like projections with the mesal 

 margin perpendicular and the lateral margin sloping and slightly crenu- 

 late. Between the first and second, and second and third pairs is a small 

 gland prominence at the base of which a large, tubular duct opens. In 

 the late second stage the derm of the dorsum becomes very heavily chi- 

 tinized and deeply pigtnented (that of the venter remaining thin) and the 

 characters of the pygidium are entirely obscured. 



The first stage larva is of the ordinary Diaspine type ; with one pair 

 of small lobes; with the antennae (Fig. 3 ID) five-segmented, the last 

 segment somewhat elongated but not annulate.
