78 AUSTKALIAN BUG. 



Crawford,* of Adelaide, S. Australia, who for some years 

 has devoted special attention to the habits of this pest, 

 with the two preceding sketches, giving very greatly 

 magnified representations of the larva and adult 

 female of the I. purchasi from photographs taken by 

 himself. 



Mr. Crawford's figure (see page 77) is of especial 

 interest, from showing the striated nature of the egg- 

 sac, and the long glassy filaments, which are character- 

 istic distinctions of the adult female of I. purchasi. 



I am not aware whether up to the present date the 

 male insect has been observed with identification in 

 S. Africa, and therefore I subjoin a description abridged 

 from that given by Prof. Eiley, and taken by him from 

 numerous specimens, both mounted and living, of the 

 Icerya purchasi Maskell, and likewise a copy of Prof. 

 Eiley's figure.f

t For above see paper, noted p. 70, on I. purchasi, by Prof. Biley, in his 

 Report as U. S. Entomologist, published by the Commissioner of Agri- 

 culture of the United States of America, and figure of the male insect 

 in the plates of illustration to the same ; and further, I must add that, 

 once again in this re-publication of my pamphlet, I desire to offer my 

 thanks to Prof. Biley for his kind courtesy in permitting me to see his 

 proof-sheets before publication and to benefit by the above observation. 

 Those who desire to study the subject in extenso cannot do better than 

 avail themselves of the immense amount of practical and scientific 

 information embodied in his paper above quoted.
