November, 1896.] 241 



posterior tuberosity bears two raised lines, the anterior one abruptly curved. There 

 are flavescent spots on the sides of the breast and abdomen. The legs are dark red, 

 strongly suffused with black. 



We are indebted for our unique example of this species to Brother 

 Matthias Newell, in recognition of whose kindness I have named the 

 species. He found it at Wailuku, Maui, in 1894. Mr. Perkins 

 believes it was brought down with timber from the mountains of West 

 Maui. Although the specimen is not in very good condition, there is 

 no doubt it belongs to a very distinct species. 



PlAGITHMTSUS CONCOLOR, 71. sp. 



Rufescens, elytris dilute brunneis, guttis albidis irregulariter positis ; 

 thorace vix perspicue quadrivittato ; pedibus elongatis, femoribus basiflavo. 



Long., 12 — 15 mm. 



Thorax slender, with a good deal of white pubescence which does not form 

 stripes, but, nevertheless, is so arranged as to be, as it were, beginning to be stripes ; 

 the anterior elevation abrupt, truncate, the two carinse on the posterior elevation 

 distinct. Elytra very densely punctured at the base, behind this with a patch of 

 dense minute punctuation, on which the delicate pubescence is slightly darker in 

 colour, behind this sparingly punctate, and somewhat shining ; the numerous flecks 

 of white pubescence are irregularly scattered, but are absent from the post basal 

 angular mark of finer punctures. Legs very long, red, the femora flavescent at base. 



Kaui ; three specimens, \ $ , 1 ? . This is a very easily distin- 

 guished species ; the only one at all like it is the Oahuan P. soUtariun. 



PlAGITHMTSUS SOLITABIUS, 11. sp. 



Rufus, prothorace vittis quatuor albidis ; elytris crebre punctatis, guttis 

 numerosis albidis irregulariter positis. Long., 10^ inm. 



Antennae entirely red, with very little setosity ; thorax dark red, with two 

 broad stripes of white pubescence on the middle, and with the flanks scantily clothed 

 with white pubescence, so as to give from above the appearance of a second pair of 

 stripes ; the two lines on the posterior callosity distinct. Elytra densely and roughly 

 punctured, the punctuation almost the same at the sides as elsewhere. Legs con- 

 colorous with body, hind tarsi with much white pubescence. 



Oahu ; a single example was found on the ridge bordering the 

 Nuuanu Valley on the south side, about 2000 ft., in October, 1892. 

 The individual appears to be a male, although the terminal joint of 

 the antennse is scarcely longer than the penultimate. 



PlAGITHMTSUS CUNEATUS, n. sp. 

 Robustus, dense punctatus, fere opacus, rufus, pirothorace abdomineque 

 nigris, elytris testaceis plaga magna communi nigricaute, densissime punctata, 

 m.inutissime albido-piibescente. Long., II LO mm.
