70 SPOLIA ZEYLANICA. 
APHIDIDA: OF CEYLON. 
By P. vAN DER Goot. (Salatiga, Java.) 
(With two Illustrations.) 

P to the present time but little has been recorded about 
the Aphidide which occur in Ceylon. The most 
important Ceylon publication on this interesting group of 
insects is a paper by Mr. H. Schouteden, of Brussels, entitled 
** Notes on Ceylonese Aphides’”’ (“‘ Spolia Zeylanica,”’ Vol. IT., 
Part VIII., 1905, pages 181-189). This paper gives us a 
fairly good description of four Ceylonese plant lice, namely, 
Greenidea artocarpi, Westw., Lachnus greeni, Schout., Oregma 
bambuse, Buckt., and Ceratopemphigus zehntnert, Schout. 
Since then little or no further systematic work has been 
done on this group of insects in Ceylon. In the course of 1913 
and 1914 a number of Aphidide, collected by the late Mr. A. 
Rutherford, the Government Entomologist of Ceylon, were 
submitted to me for determination. Most of them were either 
well-known species, or had already been previously collected 
by me in Java ; two of them appeared to be new to science. 
A list of the plant lice in this collection may, perhaps, be of 
some value in increasing our knowledge of Ceylonese insects ; 
with the kind permission of Mr. Rutherford I therefore give 
a list of the plant lice observed, together with a description of 
the two new species.
