Pseudococcus Species Found on Sugar Cane in Hawaii. 



BY E. :\r. EITRHORX. 



For nianv years there has heen luit one species of PsnirJn- 

 rocrus or Mealyhng' reported as attackino- su2:ar cane in the 

 TTa^vaiian Islands. ' Mr. Alhert Koebele, I believe, determined 

 the species as Pseudococcus calceolariae Maskell, hnt I have not 

 heen aide to find any authentic record of it. In the Fauna 

 Hawaiiensis, a list of the Coceidae of the Islands is given hy 

 the late Mr. G. W. Kirkaldy, and Pseudococcus calceolariae \^ 

 quoted as infestino; sugar cane (Koehele and Maskell). 



Again, in the Hawaiian Forester and Agricnltnrist, Vol. T, 

 Xo. 6, June, 1904, Mr. Kirkaldy lists P. calceolariae under 

 the genus Tr<'chocorys and calls it Sngar Cane Mealybug, 

 stating that it formerly caused considerable destruction to sugar 

 cane, but is of little importance now, being controlled by CJryp- 

 tolaemus uionirouzieri and Scymnus del) His. Unfortunately 

 nothing in the above papers gives us a clue as to the size and 

 color of the insect and we are at a loss to know if it is the same 

 species we find today on sugar cane. 



The only attempt to clear up the mealybugs of sugar cane 

 was in a fiapev read at the l^ovember meeting of the Hawaiian 

 Entomological Society in 1909 by Mr. Jacob Kotinsky. At 

 that time another species of Mealybug had been found by the 

 late Mr. F. W. Terry, at Hilo, and the whole subject w-as taken 

 up by Kotinsky, who after careful work settled on the two 

 species as follows : 



The large pink species which is found at the leaf bases on 

 sugar cane he determined as Pseudococcus calceolariae, "The 

 Pink Sugar Cane IMealybng". The small gray species which
