the second pair sirailar to the median pair, the third the smallest; all are distinctiy striated, longitudinally. 

 Squamae broad and rather coarsely divided. Spines very shorL Tubulär spinnerets long' and slender, some 

 of them reaching almost to the base of the pygidium. 



Resembles Aspidiohts articulatus Morgan, but may be readily distinguished by the absence of the 

 long serrated squamae at the raargin of the pygidium.

This is a common and widely distributed coccid. It feeds upon a number of different kinds of 

 plants, but it is partial to various species of Citms and Rosa, to which it is very destructive. 



Chioniaspis mytilaspiformis n. sp. (Newstead). 



Puparium of female. Form closely resembling that of the common MjfiRaapis pomonm, when 

 fixed to the slender stem of its food plant; a few forms are, however, more or less straight, but all are 

 highly convex. 



Length 2 — 2,25 mm. 



Female, adult, very elongate, narrowest in front. Antennae with two long, stout, curved spines 

 and a minute central one. Anterior Stigmata with 4 — 5 parastigmatic glands ; posterior pair without glands. 

 Abdominal and thoracic segments with large groups of dorsal glands. Pygidium with five groups of 

 circumgenital glands, the anterior group represented generally by a few isolated spinnerets. Formula of 

 three examples:

Anal orifice opposite the anterior group of spinnerets. 



Margin of pygidium ( PI. III, Fig. 8): median pair of lobes generally well developed, anterior edge 

 irregularly and coarsely serrate; second pair quite rudimentary or sometimes obsolete; third pair absent. 

 Squamae spiniform, long. Spines long, slender. Dorsal glands in large and well marked groups or bands. 



I had, at first, thought that this insect might prove to be Maskell's^J C. natalensis. It certainly 

 bears no resemblance to his estremely poor figure, neither does it agree with his diagnosis. It evidently 

 belongs to the African group and is nearly related to C. nerii Newstead. The latter has, however, a 

 much larger second pair of lobes, and the anterior group of circumgenital glands are much more numerous.

Chionaspis africana n. sp. (Newstead).

 white and faintly but irregularly striated; pellicles yellow.
