captured examples. In other species (e. g. z'itticollis) yellow 

 hairs are sometimes substituted for white. 



18. Five 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. 

 Giffard'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. siilphttrcscensr which is attached to Urcra. The species is 

 remarkably constant. 



11. Three examples from Olaa, 29 miles from Hilo on 

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

 dying trees of Pcrrottctia sandwicensis, are typical P. vitticoUis 

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

 (9), one taken at large in the same locality (8) is a very 

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

 on a dead Piptitnis tree, standing near those of Pcrrottet'ia 

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

 yellowish brown and the antennae, except the apical joints, 

 similarly pale. This example does not differ much from a 

 varietv in the original series of vitticoUis, captured by me on 

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

 lection at the British ^Museum. 



The original specimens described by Dr. Sharp were all 

 obtained from the native Ruhus. on the stems of which the)' 

 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 Hilo road. Frequent search of the native Rubus there 

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

 beetle and almost certainly those that I caught were stragglers 

 from trees of Pcrrottciia. as \lr. Giffard's observations in the 

 same locality would show. 



7. A single specimen taken in Olaa, 19 miles from Hilo. 

 on Bobea clatior, is P. vitticoUis var. longulus of the ordinary 



* The fig. in Fauna Haw. was, T believe, drawn from a (liffarcii 

 included in the series of fiulpliitri'scens.
