determined by Mr Blackburn, are of a quite different species, and not allied to the true 

 P. detrihis^. The species is remarkable for its red or pitchy red colour, very elongate 

 elytra, the abrupt narrowing of the prothorax in front, whereby a more or less distinct 

 angle is formed on each side, the very short second joint to the antennae, and the 

 deep sulci of the rostrum of the $. The squamosity has not a maculate arrangement, 

 and is very scanty on the elytra, less so on the thorax, and dense on the face, and is 

 of a golden colour in fresh examples, in which the erect flavescent setae on the elytra 

 are quite conspicuous. 



Hab. Lanai, 2000 ft. and upwards ; a very scarce species.

Elongatus, ferrugineus, setis erectis sat conspicue vestitus. Antennae ferrugineae, 

 articulo secundo minus brevi, plus minusve elongato. Pronotum minus latum, saepe 

 subelongatum, setis appressis, aliisque curvatis et suberectis vestitum, 3-impressum. 

 Elytra elongata, grossissime punctata, setis elongatis, erectis, et gracillimis vestita, 

 dorso parum vel baud convexo, angulis humeralibus productis et acutis. $ $. Long.

On account of the character of its clothing, form, and colour, this species could 

 only be confused with P. detritus Shp. of those species found in Lanai, but it is 

 distinct from that species by the form of the prothorax, less short second antennal joint, 

 and finer and longer erect setae of the elytra, as well as by the smoother and less 

 strongly grooved rostrum of the $, &c. P. epitretus on Lanai represents the P. longiilus 

 of Oahu, from which it differs in the more extremely coarse puncturation of the 

 elytra, and the longer and finer erect setae, and the former character will also readily 

 separate it from P. ferrugineus of Hawaii. The species varies greatly in size, and 

 considerably in the length of the antennae. Mirmte examples are only one-half or 

 one-third the size of the well-developed individuals. 



Hab. Lanai, mountains (2000 — ^3000 ft.) ; attached to the stems of the fronds 

 of the tree-ferns.

 et femoribus rufis, elytris maculatim squamosis. $ antennae fortius elongatae et 

 graciles, clava elongata 3-articulata. Pronotum latissimum, antice sat abrupte angus- 



' Since writing the above I find that three insects were sent by Mr Blackburn to Dr Sharp under the 

 number 449, and are marked A, B, and C. One of these is the true F. detritus, the other two are examples 

 of what I consider to be the commonest form of P. angularis, the type specimens of that species being an 

 unusual variety. These two examples are very different to one another, one being very narrow in form, a 

 variety which I have taken on several islands in company with the more usual one of P. angularis. The 

 British Museum examples under P. detritus are also vars. of P. angularis.
