cai)tured examples. In other species (e. g". i"itticolIis) yellow 

 hairs are sometimes substituted for white. 



18. I'lve examples of P. giffardi from a very long series 

 obtained on dying Suttonia (Myrsinc of Hillebrand's Flora) 

 agree entirely with those that I obtained at a rather higher 

 elevation and a few miles distant on the same tree. Mr. 

 (iiffard's great series, he informs me, exhibits no variation 

 except in the color of the hairs of the hind tibiae, which is 

 usual, and therefore no approach is made to the closely allied 

 P. sill pluir CSC ens.''' which is attached to Urcra. The species is 

 remarkably constant. 



11. Three examples from Olaa, 20 miles from Hilo on 

 the way to Kilauea, being part of a large series collected on 

 d\"ing trees of Pcrrottctia sand^vicciisis. are typical P. vitticolUs 

 (except that in one the pubescent sjiots are yellow) as also is 

 (9), one tak'cn at large in the same locality (8) is a very 

 unusual variety with the femora wholly red and (12) found 

 on a dead Pipfiinis tree, standing near those of Pcrrottctia 

 above mentioned, is a variety with the elytra to a large extent 

 yellowish brown and the antennae, excei>t the ajiical joints, 

 similarly |)ale. This example does not differ much from a 

 variety in the original scries of vitticollis, captured by me on 

 Riibiis at a considerably higher elevation, and now in the col- 

 lection at the Ilritish Museum. 



The original specimens described by Dr. Sharp were all 

 obtained from the native Ruhtis. on the stems of which they 

 were running, and several of them were in copula. Later I 

 took casual examples on the wing or settled on leaves or ferns 

 in the forest about a mile and a half below the volcano along 

 the liilo road. hTe(|uent search of the native Riibiis there 

 (imported species were not then evident) failed to yield the 

 beetle and almost certainly those that T caught were stragglers 

 from trees of Pcrrottci'ut. as Mr. (liffard's observations in the 

 same locality would show.
