Ridge. Apparently the tree had been destroyed by the wind- 

 storm of December 2-3, 1918. The standing portion of the 

 trnnk had been invaded by this beetle. The larvae had eaten 

 the whole inner layer of bark and the outer part of the wood 

 slightly. Some of the larvae had burrowed into the wood 

 for pupation, but others had remained where they had been 

 feeding beneath the bark. 



A full grown larva of Chalcolepidius erythroloma was also 

 found under the bark. Being predacious, it had probably been 

 feeding on the other larvae. 



Dolichurus stantoni. — A pair of this Philippine roach 

 parasite was exhibited by Mr. Swezey, taken on Wailupe Eidge 

 May 30th. The wasp was introduced less than two years ago. 

 This is the farthest east it is known to have spread. It has 

 already been recovered on Mt. Tantalus, Lanihuli Ridge, Iva- 

 lihi, and in the cane fields as far west as above Pearl City. 



Aloha hirkaldyi. — A specimen was exhibited, and ^^fr. Swc- 

 zey reported collecting half a dozen of this Delphacid on Eu- 

 phorbia May 25th along the trail leading up to Lanihuli from 

 the upper part of l^uuanu Valley. This insect had previously 

 been collected at Punaluu and the eastern slopes of Mt. Kaala. 



Kelisia swezeyl. — Mr. Swezey exhibited a single male speci- 

 men of this Delphacid taken June 1st on Eragrostis variabilis 

 growing at an elevation of 2800 feet above Waianae Valley. 

 This extends the range of this insect, it having been previously 

 collected in Palolo, Manoa, IsTunanu and on the east slope of 

 Mt. Kaala. 



Dictyophorodelphax mirabilis. — Mr. Swezey exhibited a 

 specimen and reported collecting this strange Delphacid on 

 Euphorbia hillebrandi at an elevation of 2500 feet above Waia- 

 nae Valley. This extends the range of the insect farther to- 

 wards the northwestern extremity of the island. The previous- 

 ly known western limit was the east side of Mt. Kaala, where 

 it was collected in 1916. It has so far been collected but a lit-
