iue it carefully. On November 23, while examining pods of 

 Acacia famesianu, infested by Caryoborus gonagra along the 

 Diamond Head road on the southeastern side of Diamond 

 Head, I found several females of the same species without 

 being able to note any indication of host relations. Since all 

 of our species hitherto found in the mountains under condi- 

 tions indicating their endemicity so far as their host relations 

 are known have been parasitic upon various lepidopterous 

 larvae, it seemed possible this species might be connected with 

 the kin tortricid (CryptopJilehia illepida). However when a 

 larva of this species had been found and placed with the Sclero- 

 deiina no interest whatever was shown. On further search, a 

 cocoon of Caryoborus gonagra was found containing the Caryo- 

 borus larva, a female Scleroderma, and three hymenopterous 

 larvae. After this, two Caryoborus cocoons were found each con- 

 taining remains of the Caryobor-us larva, a female Scleroderma, 

 and a compactly massed cluster of brownish, elliptical, hymen- 

 opterous cocoons, perhaps a dozen in a cluster. From one of 

 these, sixteen days later, the first female Scleroderma emerged. 

 Several of the Scleroderma were placed with the cocoons of 

 Caryoborus and the pupal chambers of Bruchus prosopis and 

 they immediately became interested in affecting their entrance 

 into them by tearing away the wall with their mandibles. 

 One cocoon of Caryoborus opened sixteen days later contained 

 the Caryoborus larva, the female Scleroderma,- and eight thick 

 elliptical eggs, very large in proportion to the Scleroderma and 

 scattered about indiscriminately in the cocoon. 



This finding of the female Scleroderma remaining within the 

 cocoons, not only until the eggs are laid but afterward until the 

 larvae have hatched and become full fed and pupated, is of con- 

 siderable interest and has also been observed in connection with 

 the endemic species. There would seem to be some approach 

 to maternal care of the larva. It may, however, be due merely 

 to the slow maturing of the eggs. 



In 1909, Mr. Swezey took the same Scleroderma upon a 

 Cvcad stem at Lihue, Kauai, and there are specimens of ap-
