usually to be found in drier situations. I have found them in 

 dead and decaying branches of ''mamake." 



Philodoria micropetala Walsm. — ^This .pretty little leaf-

 FAMILY CERAMBYCIDAE. 



Sub-family Cemrnhi/cini. Group Plagithmysides. 



PlagitJimysus lamarhianus P. — Males and females taken in 

 situ at 4000 feet elevation, Kilauea, Hawaii. Not uncommon. 



Callithmysus I'ohelei P. — Taken in situ on Tantalus, Oahu, 

 at 1800 feet elevation. Both sexes in numbers bred from dying 

 and wholly dead limbs gathered in same locality at 2000 feet 

 elevation. ISTot at all common. 



FAMILY CURCULIOISriDAE. 



Tribe Cryptorhynchini. 



Acalles humeraUs P. — Taken singly and in cop. under the 

 dry bark at 1800 feet elevation on Tantalus, Oahu. Both sexes

Dryopthorus crassus Shp., D. gravidus Shp., D. squalidus 

 Slip., D. distingue ndis, P., D. decUvis Shp., D. modestus Shp., 

 D. iitsignis Shp., D. insignoides P., D. oahuensis P. — Both 

 sexes of each of these species excepting oahuensis, taken in situ 

 under decaying bark of Pipturus on Tantalus at 1300 to 2000 

 feet elevation. The same species also bred from half dead 

 branches and trunks of Pipturus. Many of the species may be 

 considered ubiquitous and are by no means confined to Pipturus, 

 unless it be oahuensis, which itself is somewhat uncommon and 

 not at all abundant on this tree. Only half a dozen specimens of

 Giffard. They were obtained on his collecting trips since 1904. All 

 breeding was done at his Tantalus bungalow, at 1350 feet elevation.
