In the original description of thig species, very little 

 was given which would distinguish it from others in this 

 same genus. Eiley and Howard in Insect Life, Yol. Y, p. 

 314, described it very fully, and later in Psyche, June 

 1898, Dr. T. D. A. Cockerell described the same species 

 as Aleurodicus iridescens. Quaintance and Baker in the 

 Proceedings of the U. S. National Museum, Yol. 51, pla- 

 ced the species as Aleurodicus cocois and gave all three of 

 the early descriptions. With Piley and Howard 's speci- 

 mens, Cockerell's types and plenty of Burean material, 

 they had little doubt that the forms represented one spe- 

 cies. We have two lots of material from South America in 

 the Burean coUectiou, one taken in Yenezuela on guava 

 by Dr. A. Ernst, the other taken iu British Guiana on 

 cocoanut by G. E. Bodkin. The adult pupae vary greatly 

 in size, depending on locality and food plants. The adults 

 vary alsoin wing markings andin size. The wax secretion, 

 which is very abundant, is made up of clocculent, cottony 

 filaments, which completely covert he light yellow pupa 

 ■case. The pupa cases are placed in regular rows on either 

 side of the ribs of the leaf, and the wax secretion reaches 

 from rib to rib.
