to the Pacific coast, or are more abundant there. Lady¬ 
birds both in their larval and in their perfect state devour 
Scale-insects, Mealy Bugs, and Aphides.”* 
Whether the Rodolia iceryoe could be moved from its 
own country has } r et to be seen, but in its native land its 
spread by transmission to infested districts is mentioned 
by Mr. Bairstow as being very satisfactorily carried out. 
On Aug. 21st, 1886, he noted that he had forwarded 
“ scores of detachments of this Ladybird to different 
people,” and the information he was receiving from many 
quarters of the effect of this predaceous insect in thinning- 
off the numbers of the bug was most satisfactory. On 
Sept. 25th requests had become exceedingly numerous 
for transmission of live specimens of the Ladybird and 
another Bug-destroying insect, to be presently alluded 
to ; and Mr. Bairstow remarked that he found the Rodolia 
the best of all remedies, and on Oct. 30th he reported 
that the “Australian Bug is quite cleared out of my 
garden b}^ Rodolia.” 
Another of the enemies of the Australian Bug by which 
the increase of this pest in S. Africa is materially checked 
is a species of Chrysopa or “ Golden Eye,” one of the 
Hemerobiidce or “ Lace-wings,” a family of which the 
grubs or larvae are sometimes known, from one large 
item of their food, as Aphis Lions. Of these grubs Mr. 
Bairstow says :—“I do not wish it to be understood that 
this singular larva preys solely upon Dorthesia ” (Aus¬ 
tralian Bug.—E. A. O.). “.But that the larva 
decidedly prefers Dorthesia , if it can be obtained, I rest 
assured, both from out-of-door observations and practical 
experiments. As the insect appears to be as yet un¬ 
described, I have suggested that the specific name of 
ieeryce should be bestowed on it (provisionally at least) 
as well as on the Rodolia , with reference to the special 
article of its food. In common with other species of the 
Hemerobiidce or Lace-wings the perfect insect flies in the 
daytime, but is not readily disturbed when at rest. It is 
short-lived.”
