Keljsia eragrosticola Aluir. 



lao Valley, Maui (Giffard, Fullaway, Bridwell), Kalilii 

 Valley, Oahu (Timberlake and Bridwell). 



• Kelisia sporoboricola Kirklady. 



Taken on Erayrostls atr opt aides at an elevation of 7500 

 ft. on Haleakala, Mani (Bridwell). This has otherwise been 

 fonnd on Oahn, Mani and Hawaii near sea level on Sporo- 

 bolus virginicus. 



CICADELLIDAE. 



Three undetermined species of Xesosteles ha^e been taken. 

 One is abundant everywhere on Oahu where the bunch 

 grass grows. One was taken in lao Valley, Mani, and another 

 on E. atropioides oil Haleakala, Maui (Bridwell). 



Messrs. Griffard and Fullaway found a Cicadellid on 

 Eragrostis on Diamond Head, supposedly immigrant. The 

 genus and species have not been determined but it certainly 

 is not any of the described genera known from the Islands. 

 The recent discovery by Mr. Giffard of this species in the 

 mountains of Hawaii j)robably indicates that it is endemic. 



COCCIDAE. 



The bunch grasses are commonly infested with mealy bugs 

 supposed to be Trionymus insularis Ehrhorn. Whether other 

 «pecies occur is unknown, but the diverse species of mealy 

 bug parasites found suggests the desirability of a further in- 

 A^estigation of the Coccidae. 



A species of Pseudococcus has also been taken on Diamond 

 Head which has received a manuscript name by Mr. Ehrhorn. 



Heteeopteka. 

 LYGAEIDAE. 



A species, Nesocymus sp., has been found abundant at 

 the Nuuanu Pali. 



Two specimens of a different but closely related Lygaeid
