 wax except at the articulation of the segments where the yellow 

 colour of the body shows through. The margin bears a series of 

 white appendages equal in length, short, and equidistant. The caudal 

 extremity carries a pair of appendages about ten times as long as 

 those of the margin. The female is active up to the time of ovi- 

 position.

HOST PLANTS. 



Marantaceae Cannaap. 



Solanacese Solatium tuberosum (Potato). 



S. mdongena (Egg-plant). 



PART OF PLANT ATTACKED. 



On the Canna it was found low down between the leaf stalks, 

 whereas in the other two cases it was both on the aerial and sub- 

 terranean parts of the plant. 



REMARKS. 



This species has only been collected on three or four occasions, 

 but 1 think it will be found to be of much wider distribution than 

 our records show at present. It is not a pest in this country.
