352 NOTES ON THE HEMIPTERA OP THE HAWAIIAN ISLANDS, 



the margins and apex, which are yellow. Of the under side the 

 central portion of the breast is black, the remainder clear yellow. 



A single male of this handsome insect occurred on Maui, but I 

 regret to find that I have no record of the exact circumstances of 

 its capture. 



iV. oscillans, sp.nov. Elongatus, obscure rufus, fusco et testaceo 

 variegatus ; antennarum articulo primo gracili ; femoribus anticis 

 capite prothoraceque conjunctis longioribus ; prothorace postice 

 quam longiori vix latiori, lateribus nulla parte parallelis; hemelytris 

 alisque abdominis apicem superantibus. ^ Long. 8 mm. 



This insect is somewhat closely allied to N. siihrufus, White, 

 but is differently coloured and has both the lobes of the prothorax 

 considerably and regularly contracted towards the front. The 

 colour is an obscure reddish-brown ; the antennae are pale testaceous 

 with no other markings than an obscure infuscation of the apex of 

 the first and second joints. The legs are testaceous, obscurely and 

 finely dusted with fuscous, the apex of the femora being obscurely 

 infuscate. The apex of the costa of the corium is only slightly 

 infuscate. On the underside only the central part of the sternum 

 is infuscate, its sides being red with blackish sutures. The upper 

 surface of the hind body is infuscate, and the membrane is paler 

 than in N. nuhrufus and less variegated. In other respects it 

 resembles it. 



A specimen occurred on IMauna Loa, Hawaii, at an elevation of 

 about 4000 feet above the sea : a second specimen taken near the 

 same spot, and somewhat smaller, is probably conspecific. 



N. innotMus, White. This appears to be a widely distributed 

 species. From widely separated localities on Oahu, from Maui, 

 and fi'om Hawaii I have specimens apparently identical, save that 

 in some of them the few markings are darker and better defined 

 than in others. In most of them there are a few fuscous spots 

 near the apex of the corium which do not appear to exist in the 

 specimen I sent to Dr. White, and on which his description was 

 founded.
