126 ASPIDIOTUS CYANOPHYLLI. 



Puparium of the male (PL IX, fig. 3) circular, with 

 a slight posterior extension. Exuvire approximately 

 central ; secretional covering with a central boss and 

 concentric ring. Colour dull ochreous. 



Eggs and larvse yellow, or greenish yellow. 



Habitat. I have met with this species in Cheshire 

 only in two localities. At Eaton it occurred very 

 sparingly upon palms and orchids ; at Upton abund- 

 antly on two or three species of Aralia and Ipomaw, 

 sp. ; from Dublin (Burbidge) I have it on Cynis re- 

 voluta. It does not appear to have extended its dis- 

 tribution in this country, but is a persistent pest, and 

 when once established will continue for years upon 

 the same plants. 



Signoret's types were from a colony found in the 

 Luxembourg Gardens on Cyanophyllum r mn<jirific/urn, a 

 Venezuelan plant. Professor Comstock has met with 

 the species in the United States on various species of 

 Ficus. Mr. Green records it from Ceylon on tea, 

 cinchona, and palm plants.
