A. Zimmerman S. (Nr. 9). 
The puparia of these examples are quite typical in colour though in a few 
instances the immature specimens are pale in colour or almost white. 
A single female was also found associated with Aspidiotus destructor Sign. from 
the same locality, but the food plant in this instance was Agave mewicana. Prof. 
A. Zimmermann S8. (Nr. 12).

A few females only. 
Chionaspis lutea n. sp. (Newstead). 
Puparium of male. Smooth and flat, without any trace of carinae. 
Puparium of female. Narrowly pyriform, sometimes slightly eurved; exuviae 
and secretionary portion yellow, thin and semitransparent, revealing the sublying 
effete skins. Length 1,50—1,75 mm. 
Fig. 9. Chionaspis lutea. 
Female adult. Shape normal. Free abdominal segments protuberant. Antennae 
with a strongly curved and bifurcated spine. Pygidium (fig. 9, fringe) with two 
bilateral and one anterior groups of eircumgenital glands; formula of two examples: 
7 8 
12—10 14—11 
8—11 10—10. 
Median lobes much the longest; deeply recessed, inner free margin coarsely 
serrate; second and third pairs of lobes duplex, broad and strongly dilated, these 
are slightly longer than any of the other marginal appendages. Squames 
small; those between the lobes are more or less rudimentary and lobate in form; 
there is a similar one just beyond the third pair of lobes and immediately anterior 
to this a very broad but also very short one with an irregularly and faintly serrated 
edge. Spines all short and rather strong; one median pair; one immediately lateral 
to each pair of lobes and one or more towards the base. Sexual orifice opposite 
the lower lateral groups of circumgenital glands. Dorsal pores on abdominal segments 
small, and few in number; those at the margin of the pygidium as indicated in 
the figure.
