312 Drs. Dixey and Longstaff’s Observations 
were seen, two were secured, both males, but a third 
managed to get out of the net; they flew strongly. The 
proboscis of this butterfly when fresh is of a bright green 
colour like its eyes. On the other hand, Colias electra, 
Linn., was more restrained in its movements, and two 
males were taken. Of Pinacopteryx charina, Boisd., 
several were seen, also two or three individuals of an 
orange-tipped Z'eracolus, probably omphale, Godt. 
On the lee side of bushes which afforded a slight shelter, 
the Lycenid, Leptomyrina lara, Linn., was common, taking 
short flights and settling on the ground or on low plants. 
Nearer the sea on a sunny bank under the lee of the sand- 
hills, the very beautiful and singular Lycenid Phasius 
thysbe, Linn., was not uncommon, though apparently very 
local; it has a quick skipping flight and time allowed the 
capture of but two males and a female. In the same 
locality a pretty little rose-coloured Geometer, Stervanthia 
plectaria, Guen., was fairly common, but unfortunately 
only two specimens were brought away. On the open 
plain the familiar and cosmopolitan Nomophila noctuella, 
Schiff., was often disturbed and two were taken, as well 
as a specimen of the scarcely less widely distributed 
Phiyctenia ferrugalis, Hiibn. 
A piece of rough heathy ground near the railway-station 
yielded two Satyrids, Psewdonympha sabacus, Trim., and 
others were seen near the same spot; the genus is 
characteristic of South Africa. Close by a small Blue 
Zizera lysimon, Hiibn., was netted, as well as a fine 
variety of Sterrha sacraria, Linn. 
Under some planks lying on the sand of the river bank 
we found among smaller bugs, our first specimens of 
Physorhynchus crux, Thunb. ‘his large Reduviid, whose 
wings are so closely appressed to the abdomen that we for 
some time took it to be apterous, is very conspicuous when 
alive, the pale testaceous thorax and margins of the 
abdomen showing up the black cross upon its back, but 
the pale portions soon darken and the insect is dingy in 
the cabinet. 
Turning over stones produced a few beetles: single 
examples of Lycanthropa synwcoides, Ques., Harpalus 
exiguus, Dej., and Blenosia [Llacodes] sp., as well as two 
Trigonopus sp., the last two both represented at South 
Kensington, but unnamed. With the beetles were several 
Blattidx, Deropeltis erythrocephala, Fabr., 2, an immature
