iiie it cavefully. On November 23, while examiiiiiig pods of 

 Acacia farnesiaiia infested bj Caryohorus gonagra along the 

 J)iaiii()ii(l Head road on the southeastern side of Diamond 

 Head, 1 fonnd several females of the same species without 

 being able to note anj indication of host i-elations. Since all 

 of onr 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 {Cryptoplilebia illepida). How^ever when a 

 lai'va of this species had been found and placed with the Sclero- 

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

 cocoon of Caryohorus gonagra was fonnd containing the Caryo- 

 horus larva, a female Scleroderma, and three hymenopterons 

 larvae. After this, two Caryohorus cocoons were fonnd each con- 

 taining remains of the Caryohorus larva, a female Scleroderma, 

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

 opterons cocoons, p(>rhaps a dozen in a clnster. From one of 

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

 Several of the Sclerodcnua were placed with the cocoons of 

 Caryohorus and the pupal chambers of Bruclius prosopis and 

 they inunediately became interested in affecting their entrance 

 into them by tearing away the wall with their mandibles. 

 One cocoon of Caryohorus opened sixteen days later contained 

 the Caryohorus 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 wdth 

 the endemic species. There would seem to be some approach 

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

 to the slow maturing of the eggs. 



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

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