give the characters by which the different species seem to differ 

 from one another, than to describe them at great length and dis- 

 tinguish them from exotic forms. In some, I might almost say, 

 most, of the forms, I have had very insufficient material, and 

 there is still room for a good deal of work in collecting and 

 studying both adults and nymphs. 



TABLE OF HAWAIIAN SPECIES. 



This table wnll. I believe, aid considerably in determining the 

 species, but it is little use trying to work out these difficult forms 

 from single examples, in many cases, especially females (^^V 



1(24). Tegmina well developed; membrane wide, reaching well 

 beyond the apex of the abdomen; wings at least one-third of 

 the length of the abdomen; ocelli normal. 



2(7). Lateral margins of the pronotum only slightly sinuate, those 

 of the hind lobe not suddenly diverging, hind margin not 

 twice as wide as the collar 



3(6). Scuteilum with a median dark line down the middle; at 

 least the hind femora apically dark. 



4(5). Elongate, slender, pale testaceous, tegmina not lightly punc- 

 tured, nor specked with fuscous; fore femora obsolescently 

 marked with yellowish-orown; veins of median areas of mem- 

 brane usually simple; male hook witn dorsal margin (as seen 

 in profile at rest) of the blade strongly rounded, ventral side 

 strongly rounded, ventral side slightly emarginate. ...... . 



1. capsiformis (Germar). 



5(4). Less elongate and stouter, ashy-grey, tegmina lightly punc- 

 tured or specked with fuscous; fore femora more strongly 

 marked with fuscous; vein of median area of membrane 

 usually forked; male hook with the dorsal margin of the 



blade fairly straight, the ventral strongly bidentate 



2. blackburni (F. B. White) 



G(3). Scuteilum and legs immaculate [subg. Nesomachetcs] . . . . 

 3. kahavalu K*irkaldy. 



7(2). Lateral margins of the pronotum distinctly sinuate, those 

 of the hind lobe suddenly diverging; hind margin more than 

 twice as wide as the collar. 



8(9). Tegmina not or scarcely punctured, nor specked with fus- 

 cous; veins of the median area of the membrane scarcely 

 forked; pronotum with the hind lobe not raised strongly (as 

 seen in profile) 4. tarai Kirkaldy. 



9(8). Tegmina distinctly punctured or speckled with fuscous, es- 

 pecially near the exterolateral angle of the corium; veins of 

 the median area of the membrane shortly forked; hind lobe 

 of pronotum distinctly raised. 

 10(5). First segment of antennae shorter than ine head. 

 11(14). Colours of corium not sharply contrasted; length not more 

 than SVz mill. 



(24). 13 nesiotes is not included.
