and 15 molted skins of this larva, all of which had been east 

 between IMay 2, 1913, and Oct. 1, 1914. The larva was appar- 

 ently fnll-gTown in May, 1918, when observations began, and 

 was confined dnring the entire joeriod between two watch glasses, 

 and having nothing for food bnt dried insects. He also exhib- 

 ited a bottle of cayenne pepper badly infested with the beetle, 

 ('(ifoimna mexicana. He also stated that he had fonnd the 

 beetle, Trlholnnn feynig'tneiDn, feeding npon the paste in newly- 

 bonnd l)ooks at the College of Hawaii. 



Prof. Illingworth further stated that he had observed the 

 nyni])hs of three species of cockroaches to be compressed later- 

 ally when iirst hatched, bnt that the dorso-ventral flattening 

 takes place in a short time, the lateral compression being dne to 

 the position of the young nym])hs while crowded together in, the 

 egg-mass before hatching. 



Mr. Ehrhorn stated that he had noticed the fire ant. Sole- 

 no psis r/eminata, apparently not as abnndant as formerly, ^fr. 

 Swezey said that he had noticed them as prevalent as nsnal at 

 his home in Kaimnki. 



Mr. Ehrhorn exhibited several living specimens of the wasp, 

 Polisfes aurifer, which were parasitized by Stylopids. In one 

 case there were as many as three Stylopids between the abdom- 

 inal segments of one was]i. These was]')S were taken by ^Iv. 

 Ehrhorn and Mr. Swezey from nests on the nnder side of ])alm 

 leaves at the grounds of the Sugar Planters' Experiment Sta- 

 tion ; five of the parasitized was])s were taken from one nest, 

 an unusiuil proportion of the wasps being parasitized. 



^fr. Swezey exhibited a specimen of Conlocompm vr-^iciili- 

 (jcra (End.), this being the first record of an_y member of the 

 family Coniopterygidae in the Hawaiian Islands. 



Mr. Swezey also exhibited a portion of corrugated ]^ai>er 

 taken fi-om a packing box under his house, in the folds of which 

 wei-e several cells of a nest of a wasp resembling 

 Trijpo.vi/lon hirolor bnt somewhat smaller. Sc^ne of the cells 

 contained cocoons of the wasj), other cells contained very small i 

 sjuders. The nest was accidentally found by observing the wasp- 

 going to it with spiders. The wasp is an undetermined species « 

 not hitherto recorded in the Hawaiian Islands. 



Prof. Illingworth exhibited some books and old papers which 'il 

 liad ]»('en attacked by the termite, Calotermes marrjinipciDiis. . 

 I'bc Itooks were ruined, there being large cavities and galleries 

 that had lieeu eaten out liv the termites.
