My specimen is a male ; it occurred on Oahu, but the particu- 

 lars of its capture have been lost. 



i\^. Mauiensis, sp.nov. Oblongas, nitidus, glaber, testaceo-ebur- 

 neus, nigro et fusco maculatus ; antennis brevibus, articulo ultimo 

 incrassato • capite obscure punctulato nee ruguloso ; pronoto trans- 

 verso parce fortiter punctulato, margine antico quam mai'go posticus 

 |- breviore ; scutello fortiter 3-radiatim carinato ; corii clavique 

 venis marginibus et macidis nonnullis magnis confusis fusco- 

 nigris; membrana, conspicue fusco-umbrata; corii marginis costalis 

 parte quarta basali recta. Long. 5 mm. 



This insect is allied to JV. arboricola, White, from which it 

 differs as follows. The antennae are evidently shorter with the 

 apical joint more thickened ; and they are much more conspicu- 

 ously variegated in colour, each joint (except the last) having several 

 strongly contrasted rings of colour, — black, testaceous, or ivory 

 white. The head is black, and very smooth as compared with that 

 of arboricola, a conspicuous line of ivoiy yellow runs down the 

 beak, and another suiTounds each eye. The thorax is so mottled 

 with colour as to be difficult to describe, but it does not much 

 differ from that of arboricola, except in having the limits of its 

 colours more sharply defined and the punctuation even more 

 irregular than in that species, for it consists of about five distinct 

 wavy lines of punctures somewhat interrupted here and there, 

 among which there are many shining glabi^ous spaces. The 

 cerium is considerably more strongly and extensively clouded with 

 fuscous than in arboricola, and the membrane bears a single very 

 conspicuous and broad dark fuscous stain which runs from the 

 base to the apex. [I may observe here that in some of my speci- 

 mens of arboricola the membrane is marked with five or six 

 obscure pale fuscous clouds of which none are entire and some are 

 much shortened, — a character not mentioned in Dr. "White's 

 description]. The elytra have the peculiar shape noticed in those 

 of N. JJlackhurni, White. The femora are very distinctly Ijlack- 

 spotted, and the tibiie and tarsi are conspicuously ringed with 

 dark fuscous.
