Mr. Terrj found at Hilo and which Mr. Swezey says he now 

 finds at many other places on all the Islands, Kotinsky deter- 

 mined as Pseudococcus sacchari, 'The Gray Sugar Cane Mealy- 

 bng". I have always been in donbt about his determinations, 

 especially about P. calceolariae, as I have specimens of material 

 found on N'ew Zealand flax in California which was determined 

 for me by Professor T. D. A. Cockerell. Mr. Kotinsky had the 

 loan of my slide of this species and says that on account of 

 finding my species on K'ew Zealand flax I took it for granted 

 that it was P. calceolariae. However, he misunderstood me, 

 for I told him that Mr. Cockerell was responsible for the deter- 

 mination. Again, the chaotic condition of all Pseudococcus 

 species and the scattered literature prevented me from working 

 over the species found here. 



A short time ago while inspecting sugar cane at the H. S. 

 P. A. grounds in company with Mr. O. H. Swezey, I found 

 still another species attacking the sugar cane and I got inter- 

 ested and determined to settle the question if possible. After 

 working over the difi^erent species for a few weeks T came to the 

 following conclusion : 



The large pink species determined by INIr. Kotinsky as 

 P. calceolariae (Mask.), I determined as P. sacchari (Ckll.). 

 The oblouQ- gray species determined by Mr. Kotinsky as P. sac- 

 chari (Ckll.), T determined as P. saccharifolii Green, and the 

 third species found by Swezey and myself T determined as 

 P. hromeliae (Bouch.) although it would also fit Mr. Kuwana's 

 Pseudococcus ananassae Kuw. of which I have no specimens 

 but a copy of the descri]ition and figures. Tt might prove to be 

 a synonym of P. hromeliae. 



ISTot being satisfied with my own determinations I sent speci- 

 mens of the three species to Mr. E. E. Green of Ceylon with a 

 request to carefully go over the material. He has done so with 

 the following remarks under date of November 20, 1912 : ''I 

 determine your '^o. 1 as Pseudococcus sacchari (Ckll.). Cock- 

 erell's description of the species is, as you remark, very insuffi- 

 cient. But, so far as it goes, it fits your specimens well enough. 

 Some of your samples show an eighth joint in the antennae, 

 but this extra joint can be seen, in the making, from a trans- 

 verse lacuna in the darker chitin of the normal 4th joint, to 

 a fully developed division. The same variability occurs in the 

 Indian examples that I have identified as sacchari. I have, un- 

 fortunately, no typical examples from Cockerell himself, for
