6o 



Pale greyish or yellowish-testaceous, with two or three small spots 

 along or near the apical margin of the corium. Tlie dark markings 

 on the head, pronotum, legs and underside are very variable in hue 

 and extent, but are nearly always comparatively slight. The forms 

 living in dry, lower localities, near the coast, are very light coloured, 

 with more elongate, flimsy tegmina, but those occurring at higher and 

 wetter elevations are darker, and the tegmina are shorter and stouter; 

 these last approach koelensis somewhat, but the latter is at once dis- 

 tinguished by the much broader hind lobe of the pronotum, and the 

 species is arboreal. The dark forms of capsiformis also approach the 

 light forms of blackburni, but the male hooks are very different. (PI. 

 I, f. 1). 



R. capsiformis is practically cosmopolitan and is apparently 

 distributed over all these islands at all elevations I have also 

 seen specimens from Laysan. Superficially it is not unlike the 

 immigrant Mirid Oronomiris hawaiiensis and is found in the 

 same situations, viz : grasses, sugar-cane, etc. 



2. blackburni (White). 



Nabis blackburni F. B. White. 1878, A. M. N. H., (5), I, 373. 

 Reduviolus id. Kirkaldy, 1902, op. cit. 155 (pt.). 



This species, as above remarked, is very much like dark capsi- 

 formis, but is darker, ashy-grey, and while in capsiformis the 

 urotergitcs are pale, (perhaps a little fuscous in part), in black- 

 burni they are blackish with red or yellowish pletirites. Some, 

 specimens from Hawaii, Lanai and Maui, at higher elevations. 

 are redder and much darker and have a superficially very dif- 

 ferent habitus, but I can find no specific differences. 



At the higher elevations, are found forms with much shorter 

 tegmina (f. 17 representing the tegmen of a female I found at 

 Kilauea, Hawaii ; the membrane of the longer form of tegmen 

 is shown at f. 16). This form tends to bridge over the dis- 

 tance towards lusciosus. In all, the male hook is very character- 

 istic (f. 2). The wing is shown at f. 11 ; that of the short- 

 winged form is not very different, beyond the shortness. 



R. blackburni is distributed over all these islands at all eleva- 

 tions, more commonly perhaps, at 2000 ft. and over; I do not 

 know it from any other country, but I am not convinced that 

 it is endemic. It is to be found in grasses, sugar-cane, stag-horn 

 fern, etc., and may be beaten from low Ohias and other trees, 

 but I think that it is in the trees only accidentally. 



The nymph, when living, is dark purplish-brown above, more or 

 less variegated; scutellum yellow behind. Beneath pale yellow, abdo- 

 men apically more or less fuscate. Femora annulate near the apex. 

 Pleurites spotted with reddish.
