On one of the onter ridges of the Waianae Monntains at 

 an elevation of about a thousand feet are some exposed ])Oul- 

 (k'rs. On a ])rotected side of one of these, beneath which a 

 ])rojection made a suitable place for them were found on June 

 15, 1918, some mud nests of Sccliplwo)!. ceincuiarin-s. some of 

 the cells having in them pu])ae or tenerous adults. From others 

 they had emerged and these Avere being utilized by Odijncil for 

 their nesting places. One female Nesodtjiients Rudolplil was 

 laken within one of the cells, while others contained Icpidopter- 

 ous larvae brought there by the wasps. Two contained Ody- 

 iierus larvae, one full fed and in the other were caterpillars 

 as well. One contained a single egg, elliptical in outline about 

 twice as long as broad and suspended by a thread not <piite 

 as long as the egg itself. These were brought in for study. 



The caterpillars used for larval food were all those oY 

 A)iioihia cinif/rateUa Busck which I found later feeding Ik'- 

 neath a wel) on the flower shoots of Dracaena. The nund)er 

 employed could not well be made out on account of the l)rcak- 

 age of the cells when they w^ere removed from the rock, |)rol)- 

 ably six or eight, however, were required for a single cell. 

 Each cell of the SceUpliron was divided by an earthen parti- 

 tion and served for two cells of the Odynerus. 



The larva which was still feeding, during the day and night 

 since being brought in, had eaten all it cared for of two cater- 

 ])illars. It sinks its head into the body of the caterj)illars in 

 fi'ont of the prolegs and feeds voraciously like a cater])illai' 

 upon the substance of the caterpillar within the skin, its man- 

 dibles being in constant motion. Two of tlieso larvae were 

 conqdetely devoured and the third was half eaten.
