glands close to the anterior margin of the orifice ; posterior pair similar, parastigmatic glands apparently 

 absent. Pygidium large; circumgenital glands in five groups, formula of one example:

Anal orifice opposite the lower lateral groups of circumgenital glands ; position of vaginal orifice 

 doubtful ; dorsal glands in two short series, the first the longest, reaching to the distal part of the lower 

 lateral groups of circumgenital glands. Margin of p\'gidium (PI. III, Fig. 9) with three pairs of very short lobes 

 of which the second and third^) are duplex. There are four bilateral spines; but the squamae are either 

 entirely wanting or quite rudimentary and not traceable in the preparations. 



Length 1,25 mm. 



The distinguishing morphological characters of this insect are the more or less rudimentary lobes 

 and the relativel}' few dorsal glands. 



Habitat: Südwestafrika, Steinkopf (Klein-Namaland), 1904, L. Schultze. The food-plant is not given, 

 but the puparia were attached to the slender stems of a grass-like plant. 



Cliionaspis submidata n. sp. (Newstead). 

 Puparium of female, broadly pyriform, faintly and irregularly striated transversely ; white 

 with a trace of pale slaty grey anteriorly; larval pellicles varying from yellow to dark grey or dark brown. 

 Length 1,75 — 2 mm. 



Puparium of male white, with a sharply defined median ridge, sides rounded. 



Female, adult. Subpyriform, w-idening considerably in the region of the free abdominal Seg- 

 ments; gradualh' and wndely rounded posteriori}'; narrowest in front. Rudimentary antennae with one long 

 curved spine and two very short ones. Anterior Stigmata with 4 parastigmatic glands; posterior pair 

 without glands. Circumgenital glands in five groups, formula of two examples:

Anal orifice opposite the lower lateral groups of spinnerets. Fringe of pygidium (PI. III, Fig. 10) almost 

 denuded of appendages; median lobes very short, broad, w-ith the inner margins touching so that in some 

 examples they appear as if fused. There is a single long spine on either side of the lobes and beyond 

 them one or two smaller ones. Dorsal pores numerous and extending to the margin. 



Closely allied to Chionapsis nudata Newst. but easily distinguished from this species by the form 

 and Position of the median lobes and also the shape of the adult female. 



Habitat: Südwestafrika, Groß-Xamaland, Brukkarossberg, August 1905, Dr. L. Schultze. On an 

 unknown plant called Idbarus. 



Fiorinia sp. 



The material sent was insufficient for diagnostic purposes. It was taken at Steinkopf, Namaland, 

 and bears the number 714.

I) The third pair are wanting altogether in one example.
