 optera) With the Description of a New Genus and Species. 



2nd Paper. 



BY JOllX COLBURX BRIDWELL. 



11. The BioLoci^Y of Sclerodermus. 



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 grubs. Another investigator observed a group 

 ■of Hymenopterous larvae upon a Cerambyeid h.rva and later 

 bred from these some adult ScJerodennus. Mr. O. H. Swezey 

 bred an "endemic Hawaiian s])ecies from the larva of a wood 

 boring moth, Hyposmocoma cltilonella. The writer has found 

 several other Hawaiian species assoc'uiTcd wirli other siuiihir 

 moth larvae and a supposedly immigrant species described 

 by him as S. immigrans, was- found att:icking the eoeooued 

 larva of the Bruchid, Caryohorus (/oiKK/ra. 



The discovery of this species in associatiou with XcocJy- 

 iarhts eupliorhiae Bridwell on the Ewa Coral Plain in June, 

 1010, 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 cousidcraMc detail the
