the somite, the whole of the spots enclosed by a light brown line; two 
indistinet brown median lines joining the first and third pair of dots; 
furthermore two sub-dorsal but smaller dots in same aligment as second pair. 
On second segment near front margin two black dots connected by a 
crescent-shaped black line (opening forward). First and second segments 
reddish-brown; rd. to 10th. segment included greenish laterally, but 
from 3d. to 8th. segment included, more reddish-brown dorsally; on 
4th., 5th., 6th., 7th. and Sth., segment an 8-shaped greenish dorsal line; 
on 9th. and 10th. segment the green nmıore distinct, on 11th. segment 4 
sub-dorsal black dots, and on 12th. segment one median black dot. 
Whole body sparsely covered with stiff short black hairs, those on the 
two last segments being the longest. 
The caterpillar left the pod and suspended itself nearly horizontaly 
in a corner of the box, attached by the tail and a thoracical eirth. 
Pupa: pupa blunt, thick, rounded, tail considerably incurved, brown 
with yellow dorsal marks. 
Length of caterpillar 15 mm, of pupa about S mm. Imago was 
a female. Time of change about 3 weeks. 
Ptegryospidea mokeezi Wllgrn. 
I am indebted for the knowledge of this caterpillar to the kindness 
of Mr. E. Clark, Smithstreet Durban, who, having found it near Con- 
gella on the plant vulgarly called buckweed (Justicia Woodii ÜOlake) 
presented this single specimen to me. 
The caterpillar had tied the outer edges of a leaf together and 
formed a tube which served as shelter when not feeding, this was done 
by means of a few strong silken threads from the middle of one half 
to the other half of the leaf. 
Caterpillar: The larva is rather thick, smooth; body thickest in 
middle and attenuated to both ends, but more so to the tail, where it 
forms almost asharp point; head being very large and first somite rather 
thin the head looks, as if separated from the body by a deep constriction. 
Furthermore the head is provided on top with two prominent lobes, its 
colour is dark-purple, in great contrast to the body which is of a trans- 
parent green colour; two dorsal purple spots on first segment; a longi- 
tudinal double line of thin white streaks from head to tail and similar 
single but wider streaks above true legs and claspers; joints between 
segments slightly lighter green. Length from 32—838 mm. 
The larva attached itself in the same tube by the tail and by a 
throaeical girth fixed above on the leaf, but the underside resting on the 
midrib of it. This happened on the 6th. of November, but it shed its 
larval skin on the 9th. of the same month. 
Pupa: The pupa is bright transparent green like the caterpillar; 
oblong with a small blunt projeetion in front of the square head; two 
black minute spots above eyes, two larger black spots at beginning of the wing 
sheaths, and black spiracles on öth., 6th., Tth., Sth., 9th. and 10th. seg- 
ment; a minute sub-dorsal black streak above each. From the abdominal 
end of wingsheaths rotracts a fine thorn longer than abdomen and parallel 
to it with point slightly pinkish; point of last segment equally pinkish. 
Length of pupa 32 mm. 
A peculiarity of the chrysalis is that the attachment of the tail is
