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

 der than those of Sclevodermus manoa, and S. immigrans. 



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 CryptopMehia larvae in the pods. Much 

 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 kakeanar 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 Oaliu. 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 

 who is revising the Hawaiian species. 



3. Sct.erodee:mus immigeaxs Bridwell. 

 One 9 was found on June 11, 1918, at the tyj^e locality 

 and on being placed with Caryohorus larva showed much in- 

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

 attack were not noted at the time but the Sclerodermus 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. Though eggs were seen laid up to June V?., bur 

 some were laid after that date and the larvae reached full 

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

 was kept alive until July 24, being fed exclusively upon the 

 juices of the larvae of Caryohorus and other larvae. 



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

 Swezey bred Thyrocopa sp. and Keclysia sp. ; he has also bred from sim- 

 ilar material Opogona aurisqiiaiitosa (Butler).
