XIX. On a species of Aphideous insects infesting the bread- 

 fruit trees in Ceylon. By Prof. J. 0. Westwood,

The almost universal prevalence of species of the plant- 

 sucking family, Aphidce, will cause no surprise to ento- 

 mologists in learning that another member of that 

 family should have been found to occur on the bread- 

 fruit tree in Tropical Asia. For a knowledge of this 

 fact we are indebted to Mr. E. Ernest Green, nephew 

 of Mr. Staniforth Green, of Colombo, Ceylon, who has 

 on various occasions supplied me with materials which 

 have enabled me to lay interesting matter before the 

 Entomological Society of London. 



SipJionophora Artocarpi. 



Lsete viridis (vivens et post ultimam exuviationem) vel postea 

 magis infuscata, thorace et fasciis transversis abdominalibus fuscis; 

 oculis sanguineis ; alis hyalinis venis gracilibus, anticis rainulo 

 2do venae post-costalis pone medium ejus valde arcuato ; corniculia 

 melliferis longissimis, divergentibus setosis, obscurioribus. Species 

 magnitudine mediocri. 



On the 21st June, 1889, Mr. E. E. Green found a 

 colony of these Aphideans feeding on the young leaves 

 of the Jack-tree {Artocarpus integrifolia) in Ceylon. The 

 following is Mr. Green's description, taken from the living 

 specimens, given in his communication to his uncle, and 

 forwarded by him to me : — 



" The larvae and pupae are of a bright pale green 

 colour (changing to dull buff when placed in spirits) ; 

 the honey-secreting tubes, cornicles, or nectaries are 

 pale brownish, and the eyes crimson. The imago-state 

 is also bright green immediately after the final moult, 

 but soon darkens to brownish green ; with the thorax 

 and bands across the abdomen brown ; the eyes are
