and 15 molted skins of this larva, all of which had l>een east 

 between ]\Iay 2, 1913, and Oct. 1, 1914. The larva was appar- 

 ently full-grown in May, 1918, when observations began, and 

 was confined flnring the entire period between two watch glasses, 

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

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

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

 beetle, Tribolium ferrugineum. feeding npon the paste in newly- 

 bound books at the College of HaAyaii. 



Prof. Illingworth further stated that he had ol)servod the 

 nymphs of three species of cockroaches to lie comju-essod later- 

 ally wdien first hatched, but that the dorso-ventral flattening 

 takes place in a short time, the lateral comi^ression being due to 

 the position of the young uym])lis while crowded together in the 

 egg-mass before hatching. 



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

 )i apsis fjeininnta. apparently not as abundant as formerly, ^fr. 

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

 his home in Kaimuki. 



Mr. Ehrhorn exhibited several living specimens of tlu^ wasp, 

 Polistes aurifer, which were parasitized by Stylopids. Tu one 

 case there were as many as three Stylopids between the al)d()m- 

 inal segments of one wasp. These wasps were taken l)y 'Slv. 

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

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

 tion ; five of the parasitized wasps were taken from one nest, 

 an unusual proportion of the wasps being parasitized. 



Mr. Swezey exhibited a specimen of Coniocompsa rcsinili- 

 f/cra (End.), this being the first record of any member of the 

 family Coniopterygidae in the Hawaiian Islands. 



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

 taken from a packing box under his house, in the folds of which 

 were several cells of a nest of a wasp resembling 

 Trypoxylon hirolor but somewhat smaller. Some of the cells 

 contained cocoons of the wasp, other cells contained vciw small 

 spiders. 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 ])apers which 

 had been attacked by the termite, Calotermes marglnlppunls. 

 The books were ruined, there being large cavities and galleries 

 that had been eaten out bv the termites.
