HEMIPTERA i6 



o 



bucculae, second reaching to apical margin of mesosternum, third to apex of intermediate 

 coxae, fourth to apex of posterior coxae. Eyes prominent, not touching pronotum. 

 First segment of antennae reaching a little beyond apex of head, half the length of the 

 second which is subequal to the third and to the fourth. Mesosternum sulculate, 

 scutellar carina scarcely callose. Eyes and head a little wider than pronotal apical 

 margin ; base of pronotum truncate, three-fourths wider than apical margin, which is 

 about as wide as the length of the pronotum. Vertex three times as wide as one eye ; 

 pronotum two-fifths longer than the head. 



t. Sixth and seventh abdominal sternites slightly roundly emarginate, eighth 

 rounded posteriorly. 



$. Sixth and seventh angularly emarginate. 



Long. 4-|^ — 4f mm. ; lat. -^ mm. 



W\v,. Hawaii, Kilauea (August) ; Hualalai, 8000 ft. (August). I have seen eight 

 e.xamples of this very distinct species. 



(2) Nysins saniidersiamts, sp. nov. 



Head smooth, shining, black (except sublaterally beneath) ; an interrupted stripe 

 narrowing from vertex to clypeus, the pedicillate part of the eyes, etc., pale flavous. 

 First segment of antennae pallid, more or less black medianly ; second black basally 

 and subapically, pallid apically and subbasally ; third and fourth more or less fumate or 

 black, the former clothed with pallid hairs. Pronotum, scutellum and elytra pale cinereo- 

 flavous, the last subhyaline ; the first sparingly brunneopunctate except on the callosities 

 and on the subcallose laevigate basal margin and also along the medio-longitudinal line. 

 Scutellum posteriorly black ; apical margin of corium irregularly nebulose-fumate. Pro- 

 sternum and propleura pallid, except a black spot on the latter ; the former more or less 

 narrowly medianly black except laterobasally. Orifices and ambulacra pallid. Legs 

 pallid, femora sparingly punctured with brown. Connexivum spotted with black 

 beneath. Tibiae sometimes banded brown and pallid. Bucculae as in A^. oc/iriasis, but 

 the elevated part a little shorter. Rostrum not reaching to apex of intermediate coxae. 

 Head with eves one-third broader than lonsj'. Vertex slig-htlv narrower than the two 

 eyes together. Second segment of antennae 2^ times as long as the first, a trifie longer 

 than the third, which is subequal to the fourth. Pronotum not carinate longitudinally, 

 twice as wide at base as at apex, mediolaterally subreHexed, distinctly roundly emargi- 

 nate apically, base distinctly rounded, lateral margins sinuate. Pronotum and scutellum 

 sparingly punctured, pleura more or less punctured. Lateral margins of elytra not, or 

 only very slightly, roundly arched. 



$. Abdominal sternites blackish-brown, laterally more or less pallid, base of 

 posterior femora and tibiae black-brown. Black encroaches often on to the elytra. 

 Seventh sternite apically straight.
