observation if placed in fine glass tubes with their prev. So> 

 fine glass tubes were drawn out from the glass tubing of al»out 

 one-fourth inch which had been used to contain the twius and 

 larvae placed with these, the larger ends serving as entrance 

 chambers. These tubes were a little larger than the Hypothec 

 nemiis tunnels. Larvae placed in these tubes with the Ci-pha- 

 lonomia alone interested her, luit she seemed disturbed. On 

 adding the fine debris from the llypothnemus tunnels condi- 

 tions were more nearly normal and I was able to observe her 

 at work making her way slowly through the debris. When she 

 encountered a larva she would examine it for a moment, then 

 proceed to sting it in the head without much of an ctl'ort 

 and pass on with little consideration for her victim and no> 

 evidence of any fear of injury from its mandildes. AVhen 

 a ])iipa was encountered, the apex of the abdomen was the 

 part attacked. In this way in a very few moments all the 

 larvae and a pupa were attacked and quieted. By the next 

 morning all the larvae and pupae (six in all) were paralyzed, 

 Inil no eggs had been yet laid on the second day. 



My observations upon this species were unfortmiately 

 cut short owing to my preoccupation with the Sclerodermus^ 

 It was found possible in this way to breed the species but the 

 time recpiired to find the minute larvae necessary for l)rcc<liiig 

 the species made is ]^ossible to do only desultory work (m 

 this species. Kewly hatched Ncoclytarlus larvae, suuill Siii- 

 o.rylon larvae and Froterhinius larvae and pupae were 

 however utilized liy the adults foi- food and eggs laid 

 upon them. The larvae of a Scolytid breeding in wiliwili 

 wood (ErytJiriiia monosperma) supposed to belong to Xyle- 

 horus were somewhat slimy upon the surface and were at first 

 rejected, l)nt later upon being forced to it by necessity were 

 utilized for both feeding and breeding purposes. 



This colony at length died out through neglect after about 

 twenty adidts had been bred and the species has not since 

 been encountered. 



It is evident from the notes above that CepJialononiia re-
