(7) Rediiviolns riihrituictits, Blackburn. 



Nabis riibritiiictits Blackburn, 1889, Proc. Linn. Soc. N. S. W. (2) iii. p. 351. 



Plate V. fig. 2,1. 



Distinguished in both se.xes by the incrassate basal segment ol the antennae. Very 

 variable in colour and pattern. 



Hab. Honolulu, 2000 to 3000 ft. (June, December) ; near Waialua, Koolau range ; 

 N. Koolau (August) ; Halemano, 2000 ft. (December). I have seen 15 examples.

In a series of 55 examples, I cannot separate A', lusciosus from curtipennis. 

 A specimen of the former, donated probably by White, is in the British Museum, and 

 the type of the latter was kindly lent me by its describer. Between the two forms 

 I have before me every gradation, the different variations occurring in both sexes ; 

 there is also considerable diversity in the reduction of the elytra, one specimen being 

 almost apterous. The male hooks vary a little, but not more I think than occurs in 

 R. fcnis (Linne). R. Insciosns is remarkable for the fact that the ocelli are absent, even 

 in the most developed forms. Whether it is the brachypterous form of one of the other 

 macropterous species, I am not able to decide definitely, but I think not. 



Hab. Hawaii, Olaa (September, November) ; Kona, 2000 ft. (July, September) ;

 Valley (March); Haleakala, 4000 to 5000 ft. (March, April, October); West Maui,

 (January, February, August, September, November); Waianae, 2000 ft. (February); 

 Pipturus, back of Tantalus (December).
