The Setze of the anal lobes are 128 uw and 134 wu long while those of 
the anal ring seem to vary between 98 pw and 104 yp. 
Host Plant: Muraltia heisteria, D. C. 
Remarks: As far as is known this small species has only the 
one host plant. It was found by the writer on the Cape Flats 
east of Newlands and Rondebosch. 
Pseucdooccus fragilis n. sp. 
This material was collected on oranges at Gonna by 
Mr. C. P. Lounsbury on October 19, 1910. Unfortunately, 
I have no notes with me concerning the living insect, and 
have no particulars of the ovisac, etc. The insect is so dis- 
tinct from the other species collected in the district, however, 
that I will give the measurements from the slide material, 
and hope to complete the description on my return to the Cape. 
Adult 9: Size of largest mounted specimen 4 mm. long and 2.4 
mm. broad. The integument appears exceptionally delicate, the 
antenne unusually long, (Plate XV, Fig. 4) and the spines and sete 
unusually thin and fragile, and, in mounted specimens, very much bent.

Sete of Anal Lobes are about 230 p long. 
Sete of Anal Ring are about 192 yp long. 
Plate XVI, Fig. 6, shows the distribution of spines, etc., round 
the anal lobes. 
Type: Size mounted 4.0 mm. by 2.4 mm. 
The pores and hairs on the dermis are scant and the latter are very 
thin. Near the anterior end, on the dorsal surface are a number of long 
delicate hairs, some of which reach a length of 160 u or possibly more. 
The Antennal Segments measure: Right—64, 84, 96, 58, 74, 54, 51, 
118 wp. Left—64, 80, 96, 60, 80, 50, 56, 116 xu. 
The Sete of the anal lobes measure approximately 224 yw long, 
while those of the anal ring probably average about 196 in length.
