 Waihiku and at 1200 feet elevation in lao Valley. The latter 

 species is now known on three Islands : Oahn, Kauai, and Maui. 



Mr. Giffard also exhibited 5 specimens of Formicaleo luilsoni 

 taken in Kau, Hawaii, December, 1911. 



Mr. Kershaw told of seeing Formicaleo perjurus near Dia- 

 mond Head, Oahu, when in company with Dr. Perkins one day 

 last May. This species had not been seen for many years. 



Mr. Swezey told of seeing a specimen of Formicaleo wilsoni 

 just below Pahala Mill in Kau, Hawaii, in 1905, but was unable 

 to catch it. 



Mr. Giffard exhibited a large weevil (Sipahis gigasi) taken 

 by Mr. Kuhns on a kiawe tree at the Immigration Station 

 grounds March, 1910 ; also a large "horntail" taken by Mr. 

 Kuhns on shrubbery at Palama, May, 1910. Mr. Ehrhorn con- 

 sidered the latter the other sex of a 'horntail" exhibited by Mr. 

 Giffard, July, 1908, and was probably the American species, 

 Tremex columha. 



Mr. Ehrhorn i-eported having taken a ''harlequin" cabbage 

 bug on merchandise on dock.

 cucumber stems; Crossotarsus cxternedentatus from avacado;

Mr. ]\ruir exhibited a dead branch of Koa from Mr. Frank 

 Atherton's grounds in Manoa, that had been killed by a scale, 

 Aspidioius rapax. Some of the scales were parasitized, and the 

 following species were bred out; Aphelinus diaspidus, Cocco- 

 phagus orientalis, and Thysanus sp. 



Mr. Muir also exhibited specimens of new species of leaf 

 hoppers, to be described in a forthcoming paper.
