11. The Biology of Scleeoder^ius. 



Sir Sidney Smith Saunders bred adults of this genus 

 from twigo in which were enclosed the nests of Odynerus and 

 other wasps, the Odynerus nests containing caterpillars as 

 food for the wasp gTubs. Another investigator observed a group 

 •of Hymenopterous larvae upon a Cerambycid larva and later 

 lired from these some adult Sclerodermus. Mr. O. H. Swezey 

 bred an endemic Hawaiian species from the larva of a wood 

 Tjoring moth, Hyposmocoma chilonella. The writer has found 

 several other Hawaiian species associated with other similar 

 moth larvae and a supposedly immigrant species described 

 by him as S. immigrant, w^as found attacking the cocooned 

 larva <)f the Bruchid, Caryohorus goiuujra. 



The discovery of this species in association with NeocJy- 

 iarlus eupliorhiae Bridwell on the Ewa Coral Plain in June, 

 1919, and subsequently generally distributed over the low- 

 lands of Oahu associated with the larvae of other wood boring 

 beetles, has enabled me to work out in considerable detail the
