found at Moanahia, Oahii. On January 29 I visited ]\roanalua, 

 and in company with Mr. Maclntyre, examined some of the 

 Mango trees, one of which was badly infested with what Mac- 

 lntyre said was that terrible Indian scale. When I looked at 

 specimens through my pocket lense, I said to him that it was 

 our common Coccus acinninfitns, and I asked him if he were 

 sure that it was the same scale which compelled them to fumi- 

 gate when it was discovered, and he thought it was. On re- 

 turning to the office I looked up the record and material, the lat- 

 ter consisted of two microscope slides, one marked Coccus 

 mangiferae, Green on Mango leaves, "Moanalua, and the other 

 Coccus mangiferae. Green on Mango trees from Moanalua, at 

 Dr. Baldwin's place, Honolulu, February 13, 1907, both de- 

 termined by J. Kotinsky. Having in my collection specimens 

 of Coccus mangiferae which Mr. E. E. Green sent me, I made 

 microscope slide-mounts for comparison, and found that Mr. 

 Kotinsky's identification was wrong and that he had mistaken 

 C. acuminatus for C. mangiferae. The two species resemble 

 each other very closely, but the microscope brings out the dark 

 zone with numerous oval pores surrounding the anal plates of 

 C. fnangiferae, which is wanting in C. acuminatus. Also the 

 antennae of C. mangiferae are eight jointed, while those of C. 

 acuminatus only six or seven jointed; when six jointed the third 

 is the longest and is as long as the terminal three together. This 

 of course will remove the species from the list of Hawaiian 

 Coccids as recorded in a paper read before this Society by Mr. 

 Kotinsky on December 2, 1909. 



On January 30, while collecting on the Pauoa ti-ail, Messrs. 

 Fullaway, Kuhns and Terry found a remarkable and interest- , 

 ing Coccid. Mr. Kuhns, who found the gall infested leaves, be- 

 lieving them to be those of a Psyllid, left his material on the 

 trail, and when Mr. Teri-y followed a little later and saw the 

 leaves on the trail thought they were galls of some Coccid, and 

 ])acked them home. While examining material the next day 

 he found that his supposed Coccid was in reality a Coccid, and 

 he kindly turned the material over to me for study. 



This is the first definite record of a gall Coccid found in 

 the Hawaiian Islands, and there is no record in the checklist of 

 Coccidae, although I find a mention of the occurrence of a gall 

 Coccid here, in Bulletin 7, U. S. Bureau of Entomology, U. S. 

 Dept. of AgTic. 1897, p. 76; where Dr. L. O. Howard 'mentions
