])lant have two or more forms. At Kilaiiea, Hawaii, Ncso.sydiw 

 ipuniocicoht is very common on Li/lliriiin tiKinlnniim 11. Ti. K. 

 and Sadleria sj). ; speeimcns from the foi-mcr ])lanl arc on the 

 average much darker than specimens from the hitter. In \\w, 

 same locality N. I)1(i(h-hunii from Clcntioiilid pa mf lorn and 

 Sfcriogyne has a distinct ,<2,reen tint when alive whicli is absent 

 from s])ecimens off of Piphn-iis. 



Dnring a recent trip to Kilanea, Hawaii, ah)ni:' with .Mr. 

 W. ]\r. Giffard, we hatched ont several liuiidred nymphs of 

 Xcsosifdne Iroae Kirk, withont o-ettina; a single egg- parasite. 

 We also fonnd evidence that indicated that X. hjoe only ovi- 

 ])osits in the yonng shoots hearing leaves and N. nihcscciis only 

 in the edges of the leaves and ])hyllodia. Mr. Swezey took the 

 eggs of N. l-oae-j)]n/Jlodii in the edges of ])hyllodia. The ovi- 

 positor of X. l-oac and A', nihesccii.s are <piite distinct, the for- 

 mer being smaller, very slightly cnrved, with ahont 25-^)0 fine 

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

 slightly cnrved and recnrved, with about the same nnmher of 

 larger, square teeth along the dorso-apical half. 'I'he ovijtositoi- 

 of .V. riiJx'sreii.^ 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 previous paper,'" have been dejxis- 

 ited in the collection of the IIaw;iiian Sngar Planters' .Vsso-

L. h'liiKic hiiKiiciisix snl)S]). nov. PI. \, 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 kaiKiitiiNis, the 

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

 Length 2S> mm.; tegmen 3.6 mm.

 This snb-species is closely related to L. Icliiiac Iraiiniois'is.
