2 28 FAUNA HAWAIIENSIS 



saepe nitida, grosse punctata, plus minus irregulariter vel maculatim squamosa, setis 

 erectis gracillimis perconspicuis crebre vestita, basi scutellum juxta utrinque tuberculata, 

 humeris fortiter acute productis, lateribus saepe fere parallelis. ^ %. Long. 3 — 4 mm. 



When in fresh condition this species is readily distinguished by the distribution of 

 its squamous covering, and the very conspicuous and extremely fine erect setae, with 

 vi^hich the elytra are clothed, combined with the characters afforded by its shape, 

 the elytra being generally of more than usually parallel form, the distinct ridge formed 

 between the vertex and front of the head, the conical prominent eyes, the coarse 

 puncturation, and sometimes the shining surface of the elytra. I'here are on these, 

 in some examples, traces of longitudinal ridges, but they are generally indistinct. 

 Most closely allied, I think, to P. haleakalae, but certainly distinct. The rostrum 

 in the % of that species is quite dull, while in P. lanaiensis it is, at least to a con- 

 siderable extent, shining. 



Hab. Lanai, 2000 — 3000 ft. Not common.

An extraordinarily variable species, of which P. integer Sharp is no doubt a narrow 

 and highly-developed variety. The prothorax is very variable in length and roundness, 

 and the size of eyes, tarsal lobes, length of the antennae are all variable characters. 

 Many of the varieties of this species occur quite constantly, and it is quite probable 

 that some of these are in the process of becoming distinct species, but between such 

 forms as P. ineptus and P. integer intermediate varieties certainly occur. The larger 

 individuals attain a length of about 4 mm., the smallest I have seen is less than 2 mm. 

 in length, but the latter is quite exceptional. 



Hab. Lanai, throughout the forest, from 2000 — 3000 ft. Many examples (from 

 one to two hundred) examined.

Of this species I have seen very few examples, the type (j") in Dr Sharp's 

 collection, and four or five examples taken by myself The former is in very abraded 

 condition. The examples in the British Museum, which are placed under this name, as
