plant have two or more forms. At Kilaiiea, Hawaii, Nesosydne 

 ipomocicola is very common on Lythruni maritininm H. B. K. 

 and Sadleria sp. ; specimens from the former phmt are on the 

 average mnch darker than specimens from the latter. In the 

 same locality N'. hlackhurni from Clcvmontia parviflura and 

 Stenogyne has a distinct green tint when alive which is al)sent 

 from specimens off of PiptKni,'^. 



Dnring a recent trip to Kilanea, Hawaii, along with Mv. 

 W. M. Giffard, we hatched ont several hundred nymphs of 

 Nesosydne koae Kirk, without getting a single egg ])arasite. 

 We also found evidence that indicated that N. l-oae only ovi- 

 posits in the yonng shoots bearing leaves and X. nihescens only 

 in the edges of the leaves and phyllodia. ^Ir. Swezey took the 

 eggs of N. koae-pJiyUodii in the edges of phyllodia. The ovi- 

 positor of N. I'oae and N. nihesceiis are quite distinct, the for- 

 mer being smaller, very slightly cnrvcd, with about 25-30 fine 

 teeth along the dorso-apical half, the latter is larger, stonter, 

 slightly curved and recurved, with about the same number of 

 larger, square teeth along the dorso-apical half. The ovi])ositor 

 of N. ruhcseens var. pulla is similar to that of the species. 



The types of the new species described in this paper, as 

 well as those described in a previons paper,* have been depos-

Genus Leialoiia Kirk. 



L. lehuae Janaiensis snbsp. nov. PI. V, fig. 1. 



^ Dark brown, antennae, legs and base of abdomen lighter. 

 Tegmina dark fuscous, more intensely so down the middle; apical 

 two-thirds of costal cell (except a dark spot about one-fourth from 

 apex), subcostal cell and a mark in first two apical cells nearly color- 

 less; the clavus, a spot at fork of cubital veins and over the fifth 

 and sixth apical cells lightly fuscous; veins concolorous with mem- 

 brane, beset with very minute dark granules; wings light fuscous, 

 veins darker. 



The genitalia are near to those of the subspecies kdiidicnsix, the 

 crook at apex of aedeagus large, with its apex curved outward. 



Length 2..") mm.; tegmen 3.6 mm.
