k'cted it lit Waiinea, Kauai, in February, 1915, where it was 

 also found on Liporliacht. 



O.racis cuUarls. — Mr. liridweil called attention to the 

 abundance of this Oedenierid beetle lately. He liad collected 

 them by the dozen at the lights at the Pawaa Junction waiting 

 station. Tie said that Mr. Tiniberlake had also mentioned 

 noticing them at lights at the Hotel Macdonald. 



Dlstrlhuiiun of inserts per eJevatiu)i. — Professor Bryan 

 asked how the different members had found the distrilnition 

 of ins(H'ts to be influenced by the elevation. Mr. Swezey dis- 

 cussed tliis with regard to the Lepidoptera, sliowing that their 

 distrilnition is chiefly influenced by the food-plant, whose dis- 

 tribution is in turn influenced by elevation, and depending on 

 climatic conditions. Mr. Bridwell discussed the (juestion as to 

 Hymeno])tera, especially wasps. The latter being limited l)y 

 their habits of nesting, whether in the ground, in holes in rocks, 

 in hollow stems or excavations in rotten wood. The selection 

 of cater])illars by the sjx'cies of Odjinenis was discussed at some 

 length. In the main they took whatever was available, al- 

 though some species had favorites. Mr. Bridw(>ll mentioned 

 having observed a Crahro in California which had supplied its 

 nest with Chalcids instead of flies as the s]:)ecies of that genus 

 usually do. The nests were in galls on willow. 



ClirysUUd. — Mr. Ehrhoni reported this insect now quite 

 alumdant in Manoa Valley. He had observed one enter the 

 open cell of a ScelipJiron nest. Others reported having captured 

 it lately. Mr. Swezey i'e])orted seeing one at Wai])io the pre- 

 vious day. This is ihe farthest from Honolulu that it has been 

 observed. 



C'erapaclij/s sllresi fii. — Mr. Ehrhorn, experimenting on this 

 ant, found that tliey clustered among aphids on Purslane in his 

 bi-eeding jar. They have a peculiar habit of carrying their 

 larvae longitudinally underneath, between the legs. 



Solenopsis fjeniiinihi. — Mr. FuUaway reported fin<ling the 

 fii'e ant eating out the eggs of the melon fly in IManila. jMr. 

 Osboi'u re])oi'ted this ant as also eating out the eggs of the 

 corn leat'hopper in Manihi.
