9, 11, '20 and 30 respectively per budworm) scattered on the 

 surface. These were allowed to hatch and grow to maturity. 

 The sixth cocoon contained 35 pupae of Melittohia which had 

 consumed a budworm within its cocoon, and were lying in con- 

 tact with its driedup remains. 



Apparently the female Melittohia enters the budworm's co- 

 coon before it is entirely completed, stings the worm and de- 

 posits eggs upon it. Or it may be that after entering the 

 cocoon, she waits till the budworm is assuming the inactive 

 condition previous to the transformation to pupa, and then 

 deposits her eggs upon it ; either stinging the budworm to pre- 

 vent further transformation, or else the young larvae hatch and 

 begin eating so quickly that further transformation is pre- 

 vented. 



The egg is white, cylindrical, slightly- curved, ends rounded, 

 0.3mm. long by 0.12mm. wide. They are laid indiscriminately 

 on the surface of host, singly or several together. They hatch 

 very quickly and the young larvae feed externally upon the 

 budworm, becoming full grown in about a week. They are 

 footless grubs just a little more than Im. in length, and trans- 

 form to pupae in two or three days. They rest in the pupal 

 stage about two weeks. So many of this parasite develop upon 

 one host, that it should be a very valuable parasite upon the 

 budworm. I have not as yet ascertained whether it is generally 

 distributed throughout the Islands or not. 



The known hosts of this parasite now include Megachile, 

 Sceliphron, Pison, Odynerus of Hymenoptera; and Ereunetis 

 of Lepidoptera.

In January, 1908, a single Ceraphronid bred out of a cocoon 

 of Haplogonatopns vitiensis, collected in growing sugar cane at 

 the Experiment Station of the Hawaiian Sugar Planters' Asso- 

 ciation, Honolulu. At first it was a matter of surprise and 

 considerable doubt as to whether the cocoon from which it
