siderably stouter than the egg of PerisieroJa but are more slen- 

 der than those of Sclerodennus manoa, and S. luiinigrfuis. 



While four species of Sierola were represented in the mate- 

 rial secured from the koa, only one of these has been surely 

 associated with the Crypto phi ehia larvae in the pods. ]\Iuch 

 of the material taken from the foliage of the koa belonged to 

 another species which was taken frequently enough to assure 

 its association with some koa insect but no indication was 

 found as to which one. 



Another species of Sierola was bred (2 9 and 1 5 ) on 

 June 5, 1918, from a lepidopterous larva living within the 

 hollow twigs of recently dead Clermontia kakeana." The 

 material was taken as full fed larvae on May 26, along the 

 Manoa cliffs trail on the side of Tantalus in the S. E. Koolau 

 Mountains of Oahu. These spun their coccoons on May 27. 

 The coccoons are elliptical rich brown in color and are rather 

 closely woven. They lie nearly touching attached to the inner 

 surface of the wood in the pith cavity. 



These species of Sierola are in the hands of Mr. Fullaway 

 w^ho is revising the Hawaiian species.

 One $ was found on June 11, lOlS, at the tyj)c locality 

 and on being placed with Canjohorus hirva showed much in- 

 terest and attacked it with its mandibles. The details of the 

 attack were not noted at the time but the Sclrrodermus was 

 seen to gnaw at the larva in the mid-ventral region apparently 

 with the object of starting a flow of juices. There was a 

 marked preference for the active, full-fed larva over the pre- 

 pupal stage. Thottgb eggs were seen laid up to June 13, bur 

 some were laid after that date and the larvae rc^iched full 

 growth, but no adults were bred out from them. This female 

 was kept alive until July 24, being fed exclusivelv ujv-tu the 

 juices of the larvae of Canjohorus and other larvae. 



* From material of the same origin brought down at tlie time Mr. 

 Swezej' bred Thyrocopa sp. and Xeelysia sp. ; lie lias also bred from sim- 

 ilar material Opogona aurisquamosa (Butler).
