these observations it was evident that the insect could pass a con- 

 siderable period in an inactive state. The same date the above 

 experiments were begun, a quantity of seeds from fallen man- 

 goes from the infested district was placed in a breeding cage. 

 The idea was to determine the length of time the adults would 

 continue to appear from within the seeds. After making an 

 exit through the husks the beetles showed no tendency to remain 

 within the seeds. Apparently nearly all the weevils had left : 

 however, on October 4th, four specimens were found on the wire 

 screen above the seeds. One specimen appeared on October 15th 

 and on November 16th the seeds were all taken out and ex- 

 amined and two dead specimens were found out of the seeds on 

 the floor of the breeding cage, having issued from the seeds be- 

 tween October 15th and the last date mentioned during the ab- 

 sence of the writer. Xo weevils were contained in the remain- 

 ing seeds. 



At this time a visit was made to the infested district and all 

 traces of the weevil had disappeared. Diligent search failed to 

 show where they were until January 30th when the writer found 

 them by the hundreds in the crevices of an old board fence and 

 stone wall beneath a group of neglected mango trees in a de- 

 serted kuleana in Moanalua Valley. ( See Plate II.) The writer 

 believes that the larger portion of the weevils went into hiber- 

 nating quarters in similar places during the latter part of August 

 and the first part of September. The weevils were found in a 

 state of hibernation in that particular locality up to May 16th. 

 An active beetle was observed on the foliage of a nearby mango 

 tree on that date. At this time the fruit crop was about one- 

 half grown. 



ITS EXTRAXCE TO THE SEED 



From May 16th on, hundreds of mangoes were sectioned in 

 halves to find, if possible, evidences of the larvae within the 

 seeds. May 28th one newly developed larva was found within 

 the seed of a nearly full-grown mango. In several instances 

 Thereafter newlv hatched larvae were found within the seed and
