from nuhigenus by the longer pronotum and by the different 

 venation of the membrane. 



It is apparently restricted to the Mountains of Kauai. 



6. niibigemis Kirkaldy. 



Reduznolns niibigenus Kirkaldy, 1908, P. Haw. E. S., I, 191. 



All of the R. nwrai recorded in the "Fauna Hawaiiensis" from 

 localities other than Kauai, belong to this, though "Oahu" re- 

 quires confirmation, as I have no specimens from this island 

 now to examine. T suppose that f. 39a refers to this species, 

 but I have no males now before me. PI. I, f. 15, shows the 

 characteristic membranal venation. 



7. koclciisis (Blackburn). 



A'abis koelcnsis Blackburn, 1888. Proc. Linn. Soc. N. S. Wales 

 (2), III, 352. 



In the "Fauna Hawaiiensis," I considered this to be a syno- 

 nym of R. suhriifu'S, but it seems to be constantly slenderer, and 

 scarcely, if at all, tinged with red, and the male hook seems a 

 little more rounded dorsally. This and the following long- 

 winged forms are easily distinguished by the lateral margins 

 of the hind lobe of the pronotum being considerably divergent 

 posteriorly, the hind margin being distinctly more than twice 

 as long as the collar (fig. 6) ; the first segment of the antennae 

 is distinctly longer than the head (except R. shar planus) . 



I have, since 1902, seen orjly some specimens taken by myself 

 in Oahu, from Koa {Acacia koa) in Nuuanu Valley (about 1000 

 ft.) and from Ohia lehua (Nani [Mctrosideros] polymorpha, one 

 of the Myrtaccae) on Tantalus (about 1750 ft.). Blackburn's 

 type was from Lanai^ Koele. 



8. fniciilcutiis Kirkaldy. 



Reduviolus truciiicntus Kirkaldy, 1908, Proc. Haw. Ent. Soc, 

 I, 191. 



R. suhrufns Kirkaldy, 1902, Faun. Haw., II, PI. V, f. 38. 



This species (whose membrane is shown on f. 13) can easily 

 be distinguished from R. koelensis by its greater bulk and much 

 heavier markings ; the pattern and colouring will separate it 

 at once from R. suhriifus. It seems to be restricted to Oahu, on 

 the Honolulu Mts.. and is found on Mamake (Piptnnts albidus, 

 one of the Urticaceae).
