Pseudococcus Species Found on Sugar Cane in Hawaii. 



BY E. M. EIIRirOR>f. 



For many years there has been but one species of Pseudo- 

 coccus or Mealybug re]iorted as attacking sugar cane in the 

 Hawaiian Islands. Mr. Albert Koebele, I believe, determined 

 the species as Pseudococcus calceolariae Maskell, but I have not 

 been able to find any authentic record of it. In the Fauna 

 Hawaiiensis, a list of the Coccidae of the Islands is given by 

 the late Mr. G. W. Kirkaldy, and Pseudococcus calceolariae is 

 quoted as infesting sugar cane (Koebele and Maskell). 



Again, in the Hawaiian Forester and Agriculturist, Vol. I, 

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

 the genus Tr-echocorys and calls it Sugar Cane Mealybug, 

 stating that it formerly caused considerable destruction to sugar 

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

 tolaemus montrouzieri and Scymnus debilis. 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 paper read at the N"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 Avhole subject w^as taken 

 up by Kotinsky, Avho 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 IMealybug". The small gray species which
